The asymmetric distribution of enzymic activity between the six subunits of bovine liver glutamate dehydrogenase. Use of D- and L-glutamyl alpha-chloromethyl ketones (4-amino-6-chloro-5-oxohexanoic acid.
A method for the preparation of D- and L-glutamyl alpha-chloromethyl ketones (4-amino-6-chloro-5-oxohexanoic acid) is described. These chloromethyl ketones irreversibly inactivated bovine glutamate dehydrogenase, whereas several other related compounds had no adverse effect on the activity of the enzyme. The inactivation process was shown to be due to the modification of lysine-126. The time-courses for the inactivation and the incorporation of radioactivity from tritiated L-glutamyl alpha-chloromethyl ketone into the glutamate dehydrogenase were biphasic. The results were interpreted to suggest the involvement of 'negative co-operative' interactions in the reactivity of lysine-126. From the cumulative evidence it is argued that the first subunit of the enzyme, which takes part in catalysis, makes the largest, and the last the smallest, contribution to the overall catalysis. It is emphasized that three of the six subunits of the enzyme may possess as much as 80% of the total activity of bovine glutamate dehydrogenase.

Guanylate cyclase. Subcellular distribution in cardiac muscle, skeletal muscle, cerebral cortex and liver.
1. Guanylate cyclase of every fraction studied showed an absolute requirement for Mn2+ ions for optimal activity; with Mg2+ or Ca2+ reaction was barely detectable. Triton X-100 stimulated the particulate enzyme much more than the supernatant enzyme and solubilized the particulate-enzyme activity. 2. Substantial amounts of guanylate cyclase were recovered with the washed particulate fractions of cardiac muscle (63-98%), skeletal muscle (77-93%), cerebral cortex (62-88%) and liver (60-75%) of various species. The supernatants of these tissues contained 7-38% of total activities. In frog heart, the bulk of guanylate cyclase was present in the supernatant fluid. 3. Plasma-membrane fractions contained 26, 21, 22 and 40% respectively of the total homogenate guanylate cyclase activities present in skeletal muscle (rabbit), cardiac muscle (guinea pig), liver (rat) and cerebral cortex (rat). In each case, the specific activity of this enzyme in plasma membranes showed a five- to ten-fold enrichment when compared with homogenate specific activity. 4. These results suggest that guanylate cyclase, like adenylate cyclase, and ouabain-sensitive Na+ + K+-dependent ATPase (adenosine triphosphatase), is associated with the surface membranes of cardiac muscle, skeletal muscle, liver and cerebral cortex; however, considerable activities are also present in the supernatant fractions of these tissues which contain very little adenylate cyclase or ouabain-sensitive Na+ + K+-dependent ATPase activities.

Properties of particulate, membrane-associated and soluble guanylate cyclase from cardiac muscle, skeletal muscle, cerebral cortex and liver.
1. Guanylate cyclase of washed particles and plasma membranes showed S-shaped progress curves when titrated with either GTP or Mn2+ ions; similar results were obtained with Triton X-100-solubilized enzyme preparation from washed particles. Hill plots of these data revealed multiple metal-nucleotide and free-metal binding sites. 2. Guanylate cyclase of supernatant fractions displayed typical Michaelis-Menten properties when enzyme required excess of (free) Mn2+ (over GTP) for maximal activities; Ka (free Mn2+) was about 0.15-0.25 mM at subsaturating concentrations of GTP. 4 MnATP, MnADP, and MnGDP were found to increase the activities of both particulate and superantant enzyme, when MnGTP concentration was below saturation and free Mn2+ ion concentration was low (less than 100 muM); MnATP (50muM-1 mM) inhibited both these activities at high free Mn2+ concentration (1.5 mM) and inhibition of the particulate enzyme was greater than that of supernatant enzyme. 5. Ca2+ ions stimulated supernatant-enzyme activity; the stimulatory concentration of Ca2+ ions depended on the concentration of Mn2+ and GTP. 6. A modest stimulation of particulate guanylate cyclase by pyrophosphate (0.02-1 mM) was observed; the pyrophosphate effect appeared to be competitive with respect to GTP. At a higher concentration (2 mM), pyrophosphate produced a marked inhibition of particulate enzyme; the nature of inhibitory effect appeared complex. 7. Inorganic salts (e.g. NaCl, KCl, LiBr, NaF) produced inhibition of particulate enzyme; the degree of inhibition of Triton X-100-stimulated activity was less than that of unstimulated activity. 9. Treatment of sarcolemmal or microsomal membranes with either phospholipase C or trypsin decreased, whereas phospholipase A increased, the activity of guanylate cyclase.

Changes in conformation of reduced cytochrome c in neutral aqueous solution.
In neutral aqueous solution, high concentrations of alcohols perturb cytochrome c in such a way that reduction by means of ionizing radiation results in the formation of abnormal conformers of ferrocytochrome c resembling those previously seen on reduction in alkaline solution. These relax to normal ferrocytochrome c in about 0.1 s.

The effects of diphenyleneiodonium and of 2,4-dichlorodiphenyleneiodonium on mitochondrial reactions. Mechanism of the inhibition of oxygen uptake as a consequence of the catalysis of the chloride/hydroxyl-ion exchange.
1. Increasing the substrate concentration only decreased the inhibition of mitochondrial oxidations by diphenyleneiodonium or by 2,4-dichlorophenyleneiodonium by a small amount. 2. Diphenyleneiodonium and 2,4-dichlorodiphenyleneiodonium lowered the amounts of succinate, citrate and glutamate accumulated in the matrix of mitochondria in the presence of Cl-, but not in its absences. 2,4-Dichlorodiphenyleneiodonium decreased the accumulation of substrates by mitochondria oxidizing glycerol 3-phosphate. 3. Diphenyleneiodonium caused an alkalinization of the medium with an anaerobic suspension of mitochondria, which was only partly reversed by Triton X-100. 4. The rate of proton extrusion by mitochondria oxidizing succinate was not altered by diphenyleneiodonium or by 2,4-dichlorodiphenyleneiodium, although the rate of decay of proton pulses was increased. 5. 2,4-Dichlorodiphenyleneiodonium shifted the pH optimum for succinate oxidation by intact mitochondria from pH 7.2 to 8.0, whereas there was no effect on that of freeze-thawed mitochondria, which was pH 8.0. 6. The concentration of 2,4-dichlorophenyleneiodonium required to inhibit respiration by 50% is less the higher the absolute rate of oxygen uptake. 7. EDTA, but not EGTA [ethanedioxybis(ethylamine)-tetra-acetic acid] increased the inhibition of respiration by diphenyleneiodonium, 2,4-dichlorodiphenyleneiodonium and by tri-n-propyltin. 8. It is concluded that diphenyleneiodonium and 2,4-dichlorodiphenyleneiodonium limit respiration in Cl--containing medium by causing an acidification of the matrix, and that there are pH-sensitive sites in the respiratory chain between NADH and succinate, and between succinate and cytochrome c.

Properties and developmental regulation of an alpha-d-galactosidase from Dictyostelium discoideum.
An alpha-D-galactosidase was detected in cells of the cellular slime mould, Dictyostelium discoideum, at all stages of development. Its specific activity was highest during early development (interphase), and this accumulation of enzyme appears to require protein synthesis de novo. Its subcellular distribution differs from that of other D. discoideum glycosidases, since most activity was recovered in the soluble fraction. No evidence was obtained for more than one isoenzymic form after subjection of extracts to electrophoresis and various chromatographic procedures. It is excreted from the cell during development, but no evidence was found for an extracellular function for the enzyme.

Adenylate cyclase, guanylate cyclase and cyclic nucleotide phosphodiesterases of guinea-pig cardiac sarcolemma.
1. The activities of the enzymes involved in the metabolism of cyclic nucleotides were studied in sarcolemma prepared front guinea-pig heart ventricle; the enzyme activities reported here were linear under the assay conditions. 2. Adenylate cyclase was maximally activated by 3mM-NaF; NaF increased the Km for ATP (from 0.042 to 0.19 mM) but decreased the Ka for Mg2+ (from 2.33 to 0.9 mM). In the presence of saturating Mg2+ (15 mM), Mn2+ enhanced adenylate cyclase, whereas Co2+ was inhibitory. beta-Adrenergic amines (10-50 muM) stimulated adenylate cyclase (38+/-2%). When added to the assay mixture, guanyl nucleotides (GTP and its analogue, guanylyl imidophosphate) stimulated basal enzyme activity and enhanced the stimulation by isoproterenol. By contrast, preincubation of sarcolemma with guanylyl imidodiphosphate stimulated the formation of an 'activated' form of the enzyme, which did not reveal increased hormonal sensitivity. 3. The guanylate cyclase present in the membranes as well as in the Triton X-100-solubilized extract of membranes exhibited a Ka for Mn 2+ of 0.3 mM; Mn2+ in excess of GTP was required for maximal activity. Solubilized guanylate cyclase was activated by Mg2+ only in the presence of low Mn2+ concentrations; Ca2+ was inhibitory both in the absence and presence of low Mn2+. Acetylcholine as well as carbamolycholine stimulated membrane-bound guanylate cyclase. 4. Cylic nucleotide phosphodiesterase activities of sarcolemma exhibited both high-and low-Km forms with cyclic AMP and with cyclic GMP as substrate. Ca2+ ions increased the Vmax. of the cyclic GMP-dependent enzyme.
Adenylate cyclase, guanylate cyclase and cyclic nucleotide phosphodiesterases of guinea-pig cardiac sarcolemma. 1. The activities of the enzymes involved in the metabolism of cyclic nucleotides were studied in sarcolemma prepared front guinea-pig heart ventricle; the enzyme activities reported here were linear under the assay conditions. 2. Adenylate cyclase was maximally activated by 3mM-NaF; NaF increased the Km for ATP (from 0.042 to 0.19 mM) but decreased the Ka for Mg2+ (from 2.33 to 0.9 mM). In the presence of saturating Mg2+ (15 mM), Mn2+ enhanced adenylate cyclase, whereas Co2+ was inhibitory. beta-Adrenergic amines (10-50 muM) stimulated adenylate cyclase (38+/-2%). When added to the assay mixture, guanyl nucleotides (GTP and its analogue, guanylyl imidophosphate) stimulated basal enzyme activity and enhanced the stimulation by isoproterenol. By contrast, preincubation of sarcolemma with guanylyl imidodiphosphate stimulated the formation of an 'activated' form of the enzyme, which did not reveal increased hormonal sensitivity. 3.

Maternal blood-gases, PAo2--Pao2), hysiological shunt and VD/VT in normal pregnancy.
Serial measurements of maternal blood-gases, alveolar-to-arterial oxygen tension difference (PAO2--PaO), calculated pulmonary venous admixture (physiological shunt), deadspace/tidal volume ratio (VD/VT), and respiratory minute volume have been made in a carefully selected group of normal pregnant patients at 12, 24, 32 and 38 weeks of gestation and 5 weeks after delivery. All measurements were made in the semi-recumbent position with a left lateral pelvic tilt. Mean arterial PO2 was consistently greater than 100 mm Hg throughout pregnancy, although the value decreased from 106.4 mm Hg at 12 weeks of gestation to 101.8 mm Hg at the 38th week. Despite this decrease there was no change in (PAO2--PaO2) VD/VT, or percentage shunt with increasing gestation; nor did these values differ significantly from non-pregnant values in the same patients.

Metabolism of lorazepam.
The metabolism of lorazepam by man and four other species is reviewed. Lorazepam and its metabolites in blood, urine and faeces were identified by thin-layer and gas chromatography and by mass spectrometry. The principal metabolite in man, dog, pig and cat is the glucuronide, but the rat produces other metabolites after small doses of lorazepam, and significant amounts of the glucuronide only after high doses. Since all metabolites, except the glucuronide, occur in small quantities only in man, most studies in man have been confined to an estimation of gree and conjugated lorazepam. Blood concentrations of unconjugated lorazepam peak at 1-4 h, significant concentrations persisting for 24 h and decreasing slowly over the next 24 h. About 95% of a dose of lorazepam was accounted for in urine and faeces over a period of 5 days; 74.5% was excreted in the urine as lorazepam glucuronide and 13.5% as minor metabolites. The excretory half-life was 12 h. The blood concentrations and excretion rates are compatible with the clinical effects of lorazepam.

Comparison of the beta2-adrenoceptor selectivity of rimiterol, salbutamol and isoprenaline by the intravenous route in man.
1 The bronchodilating efficacy and the degree of beta2-adrenoceptor selectivity of rimiterol, salbutamol and isoprenaline were determined in seven subjects who exhibited histamine-induced bronchoconstriction. 2 Rimiterol, 0.5 (high dose) and 0.05 (low dose) mug kg-1 min-1, salbutamol, 0.3 and 0.03 mug kg-1 min-1, isoprenaline, 0.05 and 0.005 mug kg-1 min-1 and placebo were administered by a single intravenous injection over 6 min, and the protection against histamine-induced bronchoconstriction, changes in heart rate, pulse pressure and skeletal muscle tremor were measured. 3 Rimiterol (98%), salbutamol (96%) and isoprenaline (69%) protected against histamine-induced bronchoconstriction. For these ventilatory responses, there was a heart rate increase of 31.9, 24.7 and 44.3 beats/min for rimiterol, salbutamol and isoprenaline respectively. The three drugs produced similar increases in pulse pressure and tremor. 4 Significant dose-responses were obtained for all the parameters with each drug. 5 Isoprenaline was approximately 7 and 5 times as potent as rimiterol and salbutamol respectively in bronchodilator action when equimolar doses were compared. Similarly, isoprenaline was approximately 14 and 10 times as potent in increasing the heart rate as rimiterol and salbutamol respectively. 6 Rimiterol, a new beta-adrenoceptor stimulating drug, is an effective bronchodilator and has similar beta2-adrenoceptor selectivity to salbutamol when administered intravenously. The relative potencies and degrees of beta2-adrenoceptor selectivity of these drugs depend partly on their route of administration.

Comparison of the residual effects of two benzodiazepines (nitrazepam and flurazepam hydrochloride) and pentobarbitone sodium on human performance.
1 The residual effects of two benzodiazepines, nitrazepam (10 mg) and flurazepam hydrochloride (30 mg), and pentobarbitone sodium (200 mg) were studied by adaptive tracking and by reaction time. Performance was measured at 10 h, 13 h, 16 h, 19 h and 34 h after ingestion of each drug. Impaired performance on adaptive tracking was observed at 10 h, 13 h, 16 h and 19 h after nitrazepam and pentobarbitone sodium and at 10 h, 13 h and 16 h after flurazepam hydrochloride. Enhanced performance was observed at 34 h after nitrazepam and pentobarbitone sodium. 2 Increased reaction time persisted to 16 h after nitrazepam, flurazepam hydrochloride and pentobarbitone sodium and reaction time was also increased at 34 h after nitrazepam and pentobarbitone sodium. 3 During the morning immediately after ingestion, the subjects as a group were able to differentiate correctly between placebo and drugs, but they were not able to assess accurately the persistence of the residual effects of nitrazepam and pentobarbitone sodium. 4 Flurazepam hydrochloride would appear to be a more promising benzodiazepine than nitrazepam for use as a hypnotic by persons involved in skilled activity. There was a rapid recovery of performance during the afternoon and, unlike pentobarbitone sodium and nitrazepam, subjects retained the ability to recognize impaired skill.

Residual effects of flunitrazepam.
1 Twelve normal subjects were tested on a large battery of tests after a hypnotic dose of flunitrazepam(1 or 2 mg) and a placebo. Psychological tests were given 12 h after the drug and physiological tests 12, 15 and 18 h after the drug. 2 The tests included self-ratings of hypnotic effects and mood, the electroencephalogram, the auditory electroencephalographic evoked response, skin conductance, tapping, card-sorting and the symbol copying test. 3 Both doses of flunitrazepam were effective hypnotics according to the ratings, with an anxiolytic effect the following day. The EEG was significantly altered up to 18 h after the drug and the behavioural tests showed a motor impairment 12 h after drug administration. 4 Nearly all changes displayed linear dose-related trends.

A clinical and psychometric evaluation of flurazepam.
1 The efficacy of flurazepam (15 mg or 30 mg) as a hypnotic, and the residual effects of each dose were compared with placebo in a double-blind cross-over trial involving thirty patients in a general practice setting. Patients received each medication for one week. Daily self-ratings of onset, duration and quality of sleep, together with reports of any untoward effects were made. At the end of each period of medication psychomotor tests (reaction time, pursuit rotor, tapping speed) were administered at 09.00 hours. 2 Both doses of flurazepam were significantly more effective than placebo in inducing sleep, improving the quality of sleep and extending its duration. 3 'Hangover' effects were marked following 30 mg, but not after flurazepam (15 mg). Flurazepam (30 mg, but not 15 mg) significantly impaired performance on the pursuit rotor test and tapping speed. Flurazepam thus appears to be an effective hypnotic drug with the optimum dose for use in general practice being 15 mg at night.

Flurazepam (30 mg, but not 15 mg) significantly impaired performance on the pursuit rotor test and tapping speed. Flurazepam thus appears to be an effective hypnotic drug with the optimum dose for use in general practice being 15 mg at night.

Bioavailability and dissolution of different formulations of oxytetracycline preparations.
1 The concentration of oxytetracycline in plasma was studied by microbiological assay after oral administration of five different preparations of the antibiotic. None of these preparations had been studied previously. 2 There was a statistically significant correlation between the time required for 50% dissolution at pH 2 and biological availability, as assessed by the peak plasma level or the area under the plasma concentration-time curve. 3 The mean bioavailability of oxytetracycline was greatest with preparations of the hydrochloride, and with film-coated tablets of the dihydrate. In contrast, sugar-coated tablets of oxytetracycline dihydrate were associated with poorer dissolution characteristics and reduced biological availability.

A review of the animal pharmacology of labetalol, a combined alpha- and beta-adrenoceptor-blocking drug.
1 The animal pharmacology of labetalol, a drug that blocks both alpha- and beta-adrenoreceptors, is reviewed. 2 In isolated tissues the blockade by labetalol of both alpha- and beta-adrenoreceptors satisfied accepted critera for competitive antagonism. In contrast phentolamine was a competitive antagonist at alpha-adrenoreceptors only, and propranolol a competitive antagonist at beta-adrenoreceptors only. Labetalol was 6-10 times less potent than phentolamine in blocking alpha-adrenoreceptors and 1.5-3 times less potent than propranolol in blocking beta-adrenoreceptors. Labetalol itself was 4-8 times more potent at beta- than at alpha-adrenoreceptors. 3 In anaesthetized dogs labetalol given intravenously blocked vasopressor responses to phenylephrine positive chronotropic, vasodepressor and bronchodilator response to isoprenaline. Phentolamine blocked the effect of phenylephrine only, and propranolol the effects of isoprenaline only. Labetalol was about 7 times less potent than phentolamine in blocking alpha-adrenoreceptors, about 4 times less potent than propranolol in blocking cardiac beta1-adrenoreceptors, and 11-17 times less potent than propranolol in blocking vascular and bronchial beta2-adrenoceptors. This difference in the relative potency of labetalol arises because propranolol is a slightly more potent antagonist at beta2- than at beta1-adrenoreceptors. Labetaol itself was about 16 times more potent at cardiac beta1- than at vascular alpha-adrenoreceptors. In conscious dogs labetaol given orally blocked vasopressor responses to phenylephrine and positive chonotropic responses to isoprenaline. 4 In anesthetized dogs and pithed rats labetaol blocked alpha- or beta-adrenoreceptor-mediated responses to sympathetic nerve stimulation and intravenously administered phenylephrine or isoprenaline to approximately the same extent. 5 Labetalol does not possess partial agonist (intrinsic sympathomimetic) activity at cardiac beta1-adrenoreceptors. 6 The blocking action of labetalol both in vivo was shown to be specific for alpha- and beta-adrenoreceptors. 7 The haemodynamic effects of labetalol are attributable to its adrenoreceptor-blocking actions. The observed responses vary from one experiment situation to another depending on the balance of autonomic influences. For example, in barbitone-anaesthetized dogs, in which sympathetic tone predominates, both labetalol and propranolol reduced heart rate, contractility, output and work--effects which are attributable to beta-adrenoreceptor blockade. Labetalol differed from propranolol in decreasing rather than increasing total peripheral resistance and in causing larger falls in blood pressure at equipotent beta-adrenoreceptor-blocking doses. These differences are probably attributable to peripheral vasodilatation resulting from the vascular alpha-adrenoreceptor-blocking action of labetalol...

Pharmacological effects of labetalol in man.
1 The pharmacological effects of labetalol have been studied in normal healthy subjects. The results of these studies are reviewed. 2 In the evaluation of the beta-adrenoreceptor-blocking effects of labetalol various indices of beta-adrenoceptor blockade in man were used. Labetalol administered orally and intravenously competitively antagonized the effects of isoprenaline on heart rate and diastolic blood pressure. The beta-adrenoceptor blockade induced was regarded as 'non-selective'. In addition, labetalol produced dose-related inhibitory effects on exercise-induced increases in heart rate any systolic blood pressure and similar dose-related inhibitory effects on the tachycardia induced by valsalva's manoeuvre. Labetalol had only a modest inhibitory effect on the tachycardia induced by tilting since blood pressure was reduced on a dose-related basis. 3 Labetalol was a specific competitive antagonist of the alpha-adrenoceptor agonist effects of systemically administered phenylephrine and locally infused noradrenaline. In addition, oral and intravenous administration of labetalol reduced systolic and diastolic blood pressure in the supine, standing and sitting positions. 4 The onset and duration of the alpha- and beta-antagonist effects of oral labetalol did not seem to be dissociated in time and there was a close correlation between the change in plasma concentration and pharmacological effects. 5 In comparative studies with propranolol, similar beta-antagonist effects were observed but propranolol was 4-6 times more potent weight for weight. Precise comparison, however, was complicated by the combined alpha- and beta -effects of labetalol, especially as the predominant effect of labetalol in normotensive subjects was to reduce blood pressure; whereas the predominant effect of propranolol was to reduce heart rate. In addition propranolol had inhibitory effects on ventilatory function in normal subjects, whereas labetalol in equivalent beta-adrenoreceptor-blocking doses did not. 6 From the details of the studies reviewed it was concluded that in man labetalol possesses combined alpha- and beta-adrenoreceptor antagonist properties.

Haemodynamic effects of combined alpha- and beta-adrenoreceptor blockade after intravenous labetalol in hypertensive patients at rest and during exercise.
1 The haemodynamic effects of labetalol 50 mg intravenously were studied in 13 hypertensive patients at rest in the supine and upright positions and during exercise using percutaneous right heart and brachial artery catheterization. 2 Labetalol induced immediate significant reductions in systolic and diastolic blood pressures in all conditions. 3 Heart rate, stroke volume and cardiac output were not significantly altered in the supine position at rest but were significantly reduced in the upright position. In addition systemic vascular resistance was significantly reduced. 4 During exercise, heart-rate, cardiac output and vascular resistance were significantly reduced; stroke volume was increased. Left ventriclac filling pressures were unchanged both at rest and during exercise. 5 It was concluded that these changes resulted from blockade to both alpha- and beta-adrenoreceptor.

Combined alpha- and beta-adrenoreceptors blockade with oral labetalol in hypertensive patients with reference to haemodynamic effects at rest and during exercise.
Twelve hypertensive patients received oral labetalol treatment (average final dose 1,200 mg/d) over a period of 16 months. 2 Satisfactory blood pressure control was maintained both at rest and after exercise. 3 Plasma renin activity was significantly reduced. 4 Postural hypotension measured in this group of patients after a single dose of labetalol 50 mg intravenously was considerably reduced during long-term oral treatment. 5 No serious side-effects were observed nor were there any significant changes in haematological and biochemical variables during the period. 6 Haemodynamic data obtained in two of the patients after 16 months' treatment suggests that the haemodynamic profile observed after acute intravenous administration is maintained after prolonged oral treatment.

Labetalol, a new alpha- and beta-adrenoreceptor blocking agent, in hypertension.
1Labetalol is a new compound with antagonistic effects at both alpha- and beta-adrenoreceptor sites. 2 When given to 12 hypertensive patients at an average daily dosage of 273 mg for 7 months statistically significant reductions (compared with pretreatment values) in recumbent and standing blood pressure were observed. 3 Treatment has to be withdrawn in one patient because of vivid dreams, and dosage was reduced in one patient because of dizziness. Otherwise no side-effects of importance were noted. 4 It can therefore be concluded that labetalol offers a useful anti-hypertensive effect and that this compound is well tolerated.

Intravenous labetalol in hypertensive patients treated with beta-adrenoreceptor-blocking drugs.
1 The effect of intravenous injections of labetalol at doses of 1 and 2 mg/kg was studied in 15 patients with severe hypertension inadequately controlled by beta-adrenoreceptor-blocking drugs. 2 At a dose of 1 mg/kg there was a slight but statistically insignificant reduction in blood pressure. When 2 mg/kg was given there was a prolonged (6 h) significant reduction in lying blood pressure. At both dose levels there was a small initial increase in pulse rate but forced peak flow was not affected. 3 Side-effects were limited to transient postural hypotension and a feeling of warmth. 4 It is concluded that intravenous labetalol at a dose of 2 mg/kg is safe and effective in rapidly reducing blood pressure in patients already receiving beta-adrenoreceptor-blocking drugs.

Arterialized ear lobe blood samples for blood gas tensions.
The accuracy of arterialized blood samples both at rest and during exercise is described in comparison to simultaneous arterial blood samples. The technique was found to be reliable and sufficiently accurate for clinical exercise testing, with no significant differences for Po2 or Pco2 between the two methods.

Preparation and storage of platelet concentrates. II. Storage variables influencing platelet viability and function.
Factors affecting the viability and function of stored platelet concentrates have been investigated in a blood component programme. It was found that platelets could be maintained for up to 72 h without bacterial contamination under the following conditions: (1) surgical skin preparation at venipuncture site; (2) blood collection in CPD or ACD anticoagulant in a closed bag system; (3) centrifugation of PRP at 3000 g for 20 min; (4) storage in Fenwal PL-146, Cutter CL-2383, or McGaw plastic bags; (5) resuspension of the platelet pellet in 70 ml residual plasma; (6) storage at 22+/-2 degrees C; and (7) constant gentle mixing throughout storage. Platelet viability as determined by recovery and survival is largely maintained, as is platelet function measured by template bleeding time. Both viability and function of concentrated platelets stored at 4 degrees C are severely compromised.

Solubilization, partial purification and radioassay for the intrinsic factor receptor from the ileal mucosa.
A macromolecule which binds intrinsic factor saturated with vitamin B12 has been solubilized from the guinea-pig ileum by homogenization followed by mechanical disruption without organic solvents or detergents. This intrinsic factor 'receptor' was further purified by precipitation with 30% saturated ammonium sulphate, centrifugation at 105000 g, and filtration through Sephadex G-200. Failure to precipitate the receptor following centrifugation at 105000 g for 3 h and filtration of the receptor with the included volumes through Sepharose 4B and 6B was evidence that it was solubilized. The purification of the receptor was monitored by a radiometric assay where the intrinsic factor-[57Co]vitamin-B12 complex coupled to the solubilized receptor precipitated at 15% sodium sulphate while intrinsic factor-[57Co]B12 alone remained soluble at this salt concentration. This radioassay also permitted the in vitro study of the interaction of the solubilized receptor and intrinsic factor saturated with [57Co]B12. The receptor did not bind intrinsic factor-[57Co]B12 below pH 5 while binding was observed to pH 9.0. Binding was equivalent at 37 degrees C and 25 degrees C, but was markedly reduced at 4 degrees C and 56 degrees C and was destroyed at 100 degrees C. The receptor resisted 60 min of digestion by trypsin, chymotrypsin, pronase and subtilisin. After 180 min digestion, pronase and subtilisin inactivated 90% and 41% of the receptor respectively, whereas trypsin and chymotrypsin inactivated only 21% and 23%. Trisodium EDTA inhibited the binding of intrinsic factor-[57Co]B12 to the receptor and this inhibition could be reversed by the addition of excess Ca2+. Mg2+ and Mn2+ were less effective than Ca2+ for the activity of the receptor. Kinetic analysis of the reaction indicated a maximum velocity of 0.083 nmole IF bound B12/min with a Km of 1.36 x 10(-10) M. The solubilized receptor had a greater affinity for intrinsic factor bound to vitamin B12 than for intrinsic factor free of vitamin B12. The solubilization of this intrinsic factor receptor without chemicals suggests that it is not an integral component of the microvillus membranes hydrophobically bonded to the lipid matrix, but rather a peripheral protein weakly associated with the membrane by non-covalent interaction.

Effect of pyridoxal 5'-phosphate on the oxygen affinity of human erythrocytes.
Pyridoxal 5'-phosphate (PLP), an allosteric effector for the oxygenation of haemoglobin, was incorporated readily into erythrocytes and disappeared from them by simple passive diffusion. The disappearance of PLP from the cells was accelerated by the generation of 2,3-DPG in a medium of inosine, pyruvate and phosphate. The oxygen dissociation curve measured at an extracellular pH of 7.4 demonstrated that PLP incorporated into the cells also lowered the oxygen affinity and that PLP functionally compensated for a metabolically reduced 2,3-DPG. However, the dependency of the oxygen affinity on the intracellular PLP concentration showed a different pattern from the observed for 2,3-DPG. On the other hand, the lowering of intracellular pH by organic phosphates accumulated in the cells was much larger with PLP than with 2,3-DPG. The peculiar relationship between the oxygen affinity of erythrocytes and the intracellular PLP concentration is discussed in detail. The present study may offer a new prospect for the preservation of blood with a normal function.

Phosphorus-31 Fourier transform nuclear magnetic resonance study of mononucleotides and dinucleotides. 1. Chemical shifts.
A phosphorus-31 nuclear magnetic resonance (NMR) study of adenine, uracil, and thymine mononucleotides, their cyclic analogues, and the corresponding dinucleotides is reported. From the pH dependence of phosphate chemical shifts, pKa values of 6.25-6.30 are found for all 5'-mononucleotides secondary phosphate ionization, independently from the nature of the base and the presence of a hydroxyl group at the 2' position. Conversely, substitution of a hydrogen atom for a 2'-OH lowers the pKa of 3'-monoribonucleotides from 6.25 down to 5.71-5.85. This indication of a strong influence of the 2'-hydroxyl group on the 3'-phosphate is confirmed by the existence of a 0.4 to 0.5 ppm downfield shift induced by the 2'-OH on the phosphate resonance of 3'-monoribonucleotides, and 3',5'-cyclic nucleotides and dinucleotides with respect to the deoxyribosyl analogues. Phosphate chemical shifts and titration curves are affected by the ionization and the type of the base. Typically, deviations from the theoretical Henderson-Hasselbalch plots are observed upon base titration. In addition, purine displays a more deshielding influence than pyrimidine on the phosphate groups of most of the mononucleotides (0.10 to 0.25 ppm downfield shift) with a reverse situation for dinucleotides. These effects together with the importance of stereochemical arrangement (furanose ring pucker, furanose-phosphate backbone conformation, O-P-O bond angle) on the phosphate chemical shifts are discussed.

Reaction of yeast carboxypeptidase C1 with group-specific reagents.
The reactions between yeast carboxypeptidase C and the group-specific reagents, phenylglyoxal and iodoacetamide, have been studied in detail and the reactions of residue at the active site with N-tosyl-L-phenylalanine chloromethyl ketone and diisopropyl phosphorofluoridate have been confirmed. Modification of the enzyme by either phenylglyoxal or iodoacetamide results in the loss of peptidase activity, while esterase activity remains unchanged. Inactivation by phenylglyoxal appears to be the result of the modification of a single arginine residue, whereas inhibition by iodoacetamide can be correlated with the modification of a single methionine residue. Inactivation of the enzyme by either N-tosyl-L-phenylalanine chloromethyl ketone or diisopropyl phosphorofluoridate is the result of the modification of a single histidine and a single serine residue, respectively. The pattern of inhibition indicates certain analogies in the mechanism of yeast carboxypeptidase C to pancreatic chymotrypsin, on the one hand, and to carboxypeptidase A, on the other.

Identification and properties of the covalently bound flavin of beta-cyclopiazonate oxidocyclase.
Beta-Cyclopiazonate oxidocyclase from Penicillium cyclopium has been previously shown to contain flavin dinucleotide in covalent linkage to the protein. In the present study, a pure flavin mononucleotide peptide was isolated from the enzyme by tryptic-chymotryptic digestion, chromatography on Florisil and on diethylaminoethylcellulose, and hydrolysis with nucleotide pyrophosphatase. The flavin peptide contains 9 amino acids, including histidine in linkage to the flavin, and Asx as the N-terminal residue. The fluorescence of the flavin in the FMN peptide is profoundly quenched even at pH 3.2, where protonation of the imidazole prevents queching of the flavin fluorescence by histidine. This quenching appears to be due to interaction of the flavin with a tryptophan residue, as the quenching is abolished by oxidation of the tryptophan with performic acid. Similarly, the fluorescence of the tryptophan in the peptide is quenched, presumably by the flavin. The flavin of beta-cyclopiazonate oxidocylcase is attached, by the way of the 8alpha-methylene group, to the imidazole ring of a histidine. The aminoacylflavin isolated from the enzyme is identical in the pKa of its imidazole group, in reduction by NaBH4, and in other properties with synthetic 8alpha-(N1-histidyl)riboflavin. The pKa of the histidylriboflavin component of the oxidocyclase is 5.2 before and 5.0 after acid modification of the ribityl chain, as is found in the synthetic derivative. It is concluded that the enzyme contains the N1 isomer of histidylriboflavin and that acid hydrolysis of flavin peptides isolated from the oxidocyclase, while liberating histidylriboflavin, also causes acid modification of the ribityl chain of the flavin moiety.

Potentiometric determination of ionizations at the active site of papain.
The ionization behavior of groups at the active site of papain was determined from the pH dependence of the difference of proton content of papain and the methylthio derivative of the thiol group at the active site of papain (papain-S-SCH3). This difference in proton content was determined directly by two independent methods. One method involved potentiometric measurements of the protons released and demethylthiolation of papain-S-SCH3 with dithiothreitol, as a function of pH. The other method involved analogous measurements of the protons released on methylthiolation of papain with methyl methanethiosulfonate. The methylthio pH-difference titrations generated by these measurements indicate that ionization of the thiol group at the active site of papain is linked to the ionization of His-159. The pK of the thiol group changes from 3.3 to 7.6 on deprotonation of His-159 at 29 degrees C/20.05. Similarly, the pK of His-159 shifts from 4.3 to 8.5 when the active site thiol group is deprotonated. The microscopic ionization constants determined in this work for Cys-25 and His-159 indicate that equilibrium constant for transfer of the proton from Cys-25 to His-159 is 8--12, and that in the physiological pH range the active site thiol group exists mainly as a thiol anion.

Studies on the noncooperative binding of the Escherichia coli DNA unwinding protein to single-stranded nucleic acids.
The noncooperative binding of the Escherichia coli DNA unwinding protein to single-stranded DNA oligomers has been studied by means of equilibrium dialysis. Dialyses were performed under a number of solution and temperature conditions using oligomers of varying length and base compositions. The results of these studies, which include a Scatchard analysis of the binding, have allowed us to propose a model for the cooperative binding of the protein to single-stranded DNA. The results of experiments dealing with the interaction of the protein with single-stranded RNA are also presented.

A simple, quantitative approach to the coupling of photophosphorylation to electron flow in terms of proton fluxes.
A simple relationship between observed phosphorylation efficiencies (P/e ratios) and internal proton concentration in spinach chloroplast thylakoids has been derived. P/e ratios, varked by either changing the light intensity or by adding the energy transfer inhibitor, 4'-deoxyphlorizin, were found to change with internal proton concentration in accordance with this relationship. A quantitative prediction of the effect of uncouplers on the P/e ratio can probably also be made. By extrapolation of plots of observed P/e ratios against internal proton concentration divided by the overall rate of electron flow, a maximum intrinsic P/e of about 0.66 is obtained. Assuming that two protons appear inside thylakoids per electron transferred, a P/e ratio of 0.66 suggests that three internal protons are consumed for each ATP formed. Internal protons may be considered to be substrates for the phosphorylation reaction. Hill plots of phosphorylation rate vs. internal proton concentration also indicate that three protons are consumed for each ATP synthesized. Thus, the H+ concentration gradient behaves quantitatively, as well as qualitatively, as if it is the connecting link between electron flow and phosphorylation in illuminated thylakoids.

Properties and subcellular distribution of guanylate cyclase activity in rat renal medulla: correlation with tissue content of guanosine 3',5'-monophosphate.
The properties of the guanylate cyclase systems of outer and inner medulla of rat kidney were examined and compared with those of the renal cortex. A gradation in steady-state cyclic guanosine 3',5'-monophosphate (cGMP) levels was observed in incubated slices of these tissues (inner medula greater than outer medulla greater than cortex). This correlated with the proportion of total guanyl cyclase activity in the 100 000 g particulate fraction of each tissue, but was discordant with the relative activities of guanylate cyclase (highest in cortex) and of cGMP-phosphodiesterase (lowest in cortex) in whole tissue homogenates. Soluble guanylate cyclase of cortex and inner medulla exhibited typical Michaelis-Menten kinetics with an apparent Km for MnGTP of 0.11 mM, while the particulate enzyme from inner medulla exhibited apparent positive cooperative behavior and a decreased dependence on Mn2+. Thus, the particulate enzyme could play a key role in regulating cGMP levels inthe intact cell where Mn2+ concentrations are low. The soluble and particulate enzymes from inner medulla were further distinguished by their responses to several test agents. The soluble enzyme was activated by Ca2+, NaN3, NaNo2 and phenylhydrazine, whereas particulate activity was inhibited by Ca2+ and was unresponsive to the latter agents. In the presence of NaNo2, Mn2+ requirement of the soluble enzyme was reduced and equivalent to that of the particulate preparation. Moreover, relative responsiveness of the sollble enzyme to NaNO2 was potentiated when Mg2+ replaced Mn2+ as the sole divalent cation. These changes in metal requirements may be involved in the action of NaNO2 to increase cGMP in intact kidney. Soluble guanylate cyclase of cortex was clearly more responsive to stimulation by NaN3, Nano2, and phenylhydrazine that was soluble activity from either medullary tissue. The effectiveness of the agonists on soluble activity from outer and inner medulla cound also be distinguished. Accordingly, regulation and properties of soluble guanylate cyclase, as well as subcellular enzyme distribution, and distinct in the three regions of the kidney.

Thermal transitions of myosin and its helical fragments. Regions of structural instability in the myosin molecule.
The structural stabilities of all the familiar proteolytic fragments of myosin have been investigated in melting studies over the pH ranges 5.5-7.0 in 0.5 M KCl. All fragments except subfragment 2 undergo a melting transition manifested by the cooperative uptake of protons in the temperature range 34-47 degrees C, and these fragments experience an increase in transition temperature, Tm as the pH is increased. Subfragment 2 undergoes a melting transition in the 43-55 degrees C range, manifested by the dissociation of protons, and it experiences a decrease in Tm as the pH is increased. These results suggest that pH changes can modulate the relative stabilities of the light meromysin, subfragment-1, and subfragment-2 regions of the myosin molecule.

Relative stabilities of the two quaternary conformations of human fetal hemoglobin.
The pH dependence of several functional properties of human fetal and adult hemoglobins have been studied to determine the relative stabilities of the high and low affinity (R and T) quaternary conformations of the two proteins under different conditions. Fetal aqumethemoglobin undergoes changes in sulfhydryl reactivity, absorption spectrum, and circular dichroism in the presence of insitol hexaphospahte which are consistent with a transition from the R to T quaternary state, but only at pH values below 6.8. In adult hemoglobin this transition can be induced pH values below 7.2. Even in the absence of phosphates, the ultraviolet (uv) circular dichroism spectrum of fetal aquomethemoglobin at low pH indicates the presence of some T conformation. The initial value for the second-order rate constant for combination of fetal deoxyhemoglobin with carbon monoxide is comparable to that for adult hemoglobin in the absence of organic phosphates and is not reduced by organic phosphates as much as that for the adult protein. The apparent first-order rate constant for dissociation of CO from fully liganded fetal hemoglobin, measured by replacement with NO, increases threefold in the absence of organic phosphates, and fourfold in the presence of organic phosphates, with decreasing pH; the midpoint of the pH dependent transition occurs around 6.8. A similar increase in the apparent first-order rate constant for O2 dissociation as measured by replacement with CO, can also be seen with decreasing pH. NO-hemoglobin F can be converted to the T state even when fully liganded simply by lowering the pH, as judged by uv circular dichroism, visible difference spectrum in the region of the alpha and beta bands, and a dramatic increase in the rate of NO dissociation, measured by replacement with CO in the presence of dithionite. These results are all consistent with a model for fetal hemoglobin in which the organic phosphate site may be functionally weakened by replacement of a residue involved in ionic interactions with the negatively charged phosphate groups, but in which the low affinity T conformation is intrinsically more stable than that of adllt hemoglobin. According to this model,the differences between fetal and adult hemoglobin can be accounted for primarily in terms of the relative stabilities of R and T conformations in each of the proteins with differences in the intrinsic properties of the individual conformations contributing effects of only secondary importance.

Adenine nucleotide metabolism of blood platelets. IX. Time course of secretion and changes in energy metabolism in thrombin-treated platelets.
Changes in the energy metabolism of washed human platelets were compared with the kinetics of secretion induced by thrombin (5 units/ml). A 50% decrease in the level of metabolic ATP (3H-labelled), which was essentially complete in 30s, was matched in rate by adenine nucleotide secretion from storage in dense granules. Incubation of platelets with antimycin before thrombin addition increased the rate of fall in metabolic ATP, but did not affect the rate of adenine nucleotide secretion. beta-N-Acetylglucosaminidase secretion, which was slower than adenine nucleotide secretion in control platelets, was noticeably inhibited by antimycin, confirming previous reports that different regulatory mechanisms exist for dense and alpha-granule secretion. The rates of rephosphorylation of metabolic ADP to ATP via glycolysis and oxidative phosphorylation were estimated by measuring lactate production and O2 consumption in resting and thrombin-stimulated platelets and compared to the level of metabolic ATP (9-10 nmol/mg of platelet protein in the resting state). The rate of ATP production was stimulated at least two fold from 12 nmol to 24 nmol/min/mg within seconds of thrombin addition. This increased rate was maintained over the observed period of 5 min although the level of metabolic ATP had decreased to 4-5 nmol/mg within 30 s; the turnover of the remaining metabolic ATP thus increased four fold over the resting state although the actual stimulation of energy production was only two fold.

Ammonia production and pathways of glutamine utilization in rat kidney slices.
Ammonia production from glutamine was studied in slices from non-acidotic and acidotic rat kidneys. Slices from non-acidotic kidneys made 53% as much ammonia from D-glutamine as from L-glutamine during the initial 15 min of incubation. Thereafter the production rate from the L-isomer accelerated while that from the D-isomer remained constant. The accelerated rate of ammonia production from L-glutamine was dependent upon tissue swelling since prevention of swelling reduced the production rate. Swelling activates the mitochondrial glutaminase I pathway as evidenced by the rise in ammonia produced per glutamine utilized ratio as well as by the accelerated rate of CO2 production derived from the oxidative disposal of glutamin's carbon skeleton. Cortical slice swelling activates the mitochondrial pathway in a manner not unlike that seen in vivo during chronic acidosis and may reflect increased permeability to glutamine. Acidotic rat kidneys are not swollen in vivo while cortical slices initially produce 4-fold more ammonia than do non-acidotic slices. After 15 min, this 4-fold difference in total ammonia production drops to only a 2-fold difference due to the swelling-induced activation of the mitochondrial pathway. Consequently, slice swelling obliterates the important fact that ammonia production by the mitochondrial pathway is 15-fold greater in acidotic than in non-acidotic kidneys.

Effect of imidazole on renal gluconeogenesis.
The metabolic effects of imidazole were tested in rat renal cortex. Imidazole enhanced the activity of renal cortical phosphodiesterase in vitro. Imidazole inhibited glucose production in a dose-dependent fashion from a variety of substrates in the gluconeogenic pathway proximal to the triose phsophates. The stimulation in renal gluconeogenesis resulting from isoproterenol and parathyroid hormone was inhibited by imidazole. These changes correlated with an inhibition of the augmented levels of renal cortical cyclic AMP levels produced by these hormones. These studies indicate that imidazole is an effective activator of phosphodiesterase in intact renal cells and lend further support to the suggestion that the stimulation of renal gluconeogenesis produced by isoproterenol and parathyroid hormone is mediated by a release of cyclic AMP.

Vitamin B-6-catalyzed beta-elimination of serine and O-phosphoserine. Qualitative and quantitative aspects of catalytic influences at the rate-limiting step, a comparison with the rate of enzymatic beta-elimination.
The overall reaction rates for the beta-elimination of serine and O-phosphoserine, catalyzed by various vitamin B-6 analogs (pyridoxal 5'-phosphate, 5'-deoxypyridoxal and N-methylpyridoxal 5'-phosphate) in the presence or absence of Cu2+ ions, are determined. The comparison of the pH-dependence of the molar activities of the three vitamin B-6 aldehydes in beta-elimination of serine enables the characterization of the different active Schiff base species and the single catalytic events. The Schiff base which has a positive charge on the pyridine ring nitrogen and a fully ionized phosphate group shows the highest molar activity. The phosphate group acts as an intramolecular general base catalyst, most probably at the alpha-carbon proton of the amino acid. Furthermore general acid catalysis by buffer species occurs at the beta-hydroxy group serine. These facts together provide a kinetically unambiguous description of the mechanism of the reaction: the removal of the proton at the alpha-carbon atom of serine is the rate-limiting step and is followed by the more rapid elimination of the b-hydroxy group of serine. The forward rate constant of the rate-limiting step is calculated for each of the reactions mentioned. The rate constants are compared with respect to the effectiveness of the individual catalytic components in the vitamin B-6-dependent beta-elimination. For optimal conditions the reaction of O-phosphoserine is faster by a factor of 10(4) in the velocity of the beta-elimination than the corresponding acid-catalyzed beta-elimination of serine. For the eliminations at the alpha- and beta-carbon atoms of O-phosphoserine in vitamin B-6-catalysed reactions a common transition state is discussed. From a comparison of the fastest vitamin beta-6-dependent model reaction with the rate of an enzymatic beta-elimination it is suggested that for those beta-elininating enzymes where the rate-limiting step is the same as in the model, the catalytic components mentioned could suffice to explain the velocity of the rate-limiting step.

Properties and subcellular localization of CMP-N-acetylneuraminic acid hydrolase of calf kidney.
The properties and subcellular distribution of CMP-N-acetylneuraminic acid (CMP-NAcNeu) hydrolase were studied in the cortex of calf kidney. The pH optimum was 9.0 in both Tris - HCl and glycine/NaOH buffer. The apparent Km was 0.47 mM and the apparent V 15.3 mumol/h/g wet wt of calf kidney cortex. A stimulation by divalent metal ions (Ca2+ and Mg2+) was demonstrated for the hydrolase. In the presence of Triton X-100 an increase in enzyme activity was observed. CMP-NAcNeu hydrolase was inhibited by EDTA, beta-mercaptoethanol, nucleoside phosphates and nucleotide-sugars. The inhibition was more pronounced when a sub-optimal CMP-NAcNeu concentration was used. The enzyme appeared to be localized in the plasma membranes. In the plasma membrane preparation of calf kidney cortex, which was derived mainly from the proximal tubule cells, the yield of CMP-NAcNeu hydrolase (13%) and its increase in specific activity (9-fold) was as high as for the plasma membrane marker enzymes. From subcellular distribution studies it appeared that the enzyme was localized mainly at the bursh border side of the plasma membrane of the proximal tubule cell.

In the plasma membrane preparation of calf kidney cortex, which was derived mainly from the proximal tubule cells, the yield of CMP-NAcNeu hydrolase (13%) and its increase in specific activity (9-fold) was as high as for the plasma membrane marker enzymes. From subcellular distribution studies it appeared that the enzyme was localized mainly at the bursh border side of the plasma membrane of the proximal tubule cell.

Localization and some properties of lysosomal dipeptidases in rat liver.
1. The rates of hydrolysis of 26 synthetic dipeptides by extracts from highly purified lysosomal fractions from rat liver at pH 5.0 and by whole liver homogenates at pH 7.4 have been determined. Extracts from the lysosomal fractions hydrolysed most peptides at a lower rate per mg protein than the homogenates, and some peptides not at all. 2. Properties of two dipeptidases present in the extracts from the lysosomal fractions, splitting Ile-Glu and Leu-Gly, respectively, were studied in greater detail. The enzyme that hydrolysed Ile-Glu was strongly activated by dithiothreitol, showed optimal activity at pH 4.5 and had a molecular weight of about 120 000. Leu-Gly dipeptidase did apparently not contain an essential thiol group and had a molecular weight of approx. 90 000. It showed maximal activity at pH 6.5. 3. After differential centrifugation of liver homogenates, Ile-Glu and Leu-Gly-splitting activities were determined in the fractions, under the optimal conditions mentioned above. The Ile-Glu-hydrolysing enzyme activity showed about the same distribution as the lysosomal marker enzyme acid phosphatase. Leu-Gly-splitting activity, however, was largely present in the cytosol fraction, with only a small peak in the lysosomal fraction. We obtained evidence that the activities present in the lysosomal fraction and in the cytosol fraction were due to different enzymes, and that one of these enzymes was localized exclusively in lysosomes. 4. It is concluded that some dipeptides originating from intralysosomal proteolysis might be split by lysosomal dipeptidases, whereas others are probably hydrolysed only in the extra-lysosomal compartment of the cell.

Some properties of erythrocuprein treated by organic solvents.
The effect of various types of organic solvents on the properties of bovine erythrocuprein was studied. Three organic solvents were found in which the protein is soluble, these were: dimethyl sulfoxide, formamide and N-methylformamide. It was shown that in formamide and dimethyl sulfoxide media the protein possees superoxide dismutase activity, but in N-methylformamide the protein has negligible activity. In organic solvents the substrate (superoxide radical) and solvated electron result in reduction of the protein copper. At high concentrations of superoxide radical or solvated electrons an inactivation of protein and stabilization of superoxide radicals was noted. The stabilization is most pronounced in N-methylformamide. The protein that is reduced by the radical or the solvated electron may be reoxidized by molecular oxygen, the latter being reduced to the superoxide radical.

Oxygen equilibrium characteristics of adult and fetal hemoglobin of Japanese monkey (Macaca fuscata).
Adult hemoglobin and fetal hemoglobin were obtained from Japanese monkey (Macaca fuscata) and their oxygen equilibrium characteristics were studied. (1) The oxygen affinity of fetal hemoglobin was higher than that of adult hemoglobin both in the presence and absence of 2,3-diphosphoglycerate. The presence of diphosphoglycerate lowers the oxygen affinity of adult hemoglobin much greater than does that of HbF and the diphosphoglycerate levels of red cells of adult and newborn monkeys are about the same. (2) The intensity of the Bohr effect, as expressed by -deltalogP50/deltapH, at pH 7.4 was in the order of fetal hemoglobin-diphosphoglycerate greater than adult hemoglobin-diphosphoglycerate greater than fetal hemoglobin greater than adult hemoglobin.

Studies on the binding of FMN by apoflavodoxin from Peptostreptococcus elsdenii, pH and NaCl concentration dependence.
1. The pH and ionic strength dependence of the interaction of FMN with apoflavodoxin has been studied by fluorometry in the pH region 2-5, at 22 degrees C. 2. The rate constant of dissociation and the dissociation constant were experimentally determined; the rate constants of association were claculated at a given pH value. These constants depend on the ionic strength. The plots of these constants against the square root of the ionic strength are straight. 3. Our data have been interpreted in terms of the Brönsted theory, which relates chemical reaction rates to ionic strength. The data indicate that the apoenzyme reaches its maximum net positive charge at pH 2.0-2.6. The calculated net charge in this pH region is between 11 and 12 and is in agreement with the theoretical value of 12 as deduced from the primary structure of the protein. The isoelectric point of the holoenzyme is about 4. 4. The rate constant of association extrapolated to zero ionic strength is 3.2-10(5)M-1-s-1 and is pH-independent. 5. The rate constant of dissociation and the dissociation constant extrapolated to zero ionic strength depend on the pH. The results are explained by assuming that there are two protein ionizations with a pK value of 3.4; these ionizing groups are possibly close to the FMN binding site.

Alkalin titrations of human somatotropin, human choriomammotropin and ovine prolactin by circular dichroism and fluorescence.
Structural transitions occurring during the alkalin titration of human somatotropin, human choriomammotropin, and ovine prolactin have been investigated by means of circular dichroism and fluorescence emission spectra. Human somatotropin exhibited an isodichroic point at 287 nm, with all spectral changes being reversed upon back titration from pH 12.50 to pH 8.0. Fluorescence quenching as a function of pH produced a simple sigmoidal curve. Human choriomammotropin exhibited an isodichroic point at 288 nm. The fluorescence and circular dichroism spectra of this protein were found to be reversible between pH 8.0 and 11.0. However, on titration above pH 11, the isodichroic point and the reversibility of the circular dichroism spectra were lost. This conformational transition was accompanied by a sharp increase in fluorescence quantum yield. The circular dichroism spectra of ovine prolactin showed essentially no change on titration to pH 11.0. However, between pH 11.0 and 12.0, a sharp conformational transition was observed similar to that seen in human choriomammotropin, but not exhibiting the same increase in fluorescence quantum yield. The fluorescence titration of prolactin was found to be essentially reversible upon back titration from pH 12.5, although the circular dichroism spectra were not reversible from this pH.

A pH-dependent conformational change in the coat protein subunits from potato virus X.
Both the circular dichroism and fluorescence spectra of the dissociated coat protein subunits from potato virus X changed substantially over the pH range 8 to 4, irreversible changes resulted below pH 4, with tyrosyl and tryptophanyl residues affected most. The titration curves show a pKa of about 5.6 and do not require cooperative interactions between the coat protein subunits, thus they are in marked contrast to titrations of tobacco mosaic virus A-protein. The spectra of the intact virus were little changed between pH 8 and 4 and suggested that the coat protein was locked into a conformation similar to that of the subunits in solution at pH 7. It is proposed that the pH induced conformational change is responsible for determining the acidic branch of the pH profile for reconstitution of potato virus X from its dissociated coat protein subunits and RNA.

The variation of magneto-optical rotatory dispersion with pH for carp deoxyhemoglobin in the presence and absence of inositol hexaphosphate was interpreted as a pH-induced allosteric transition between the structures of high and low ligand affinity (the R and T states in terms of the two state model of cooperativity). Increasing the pH from 6 to 11 causes a decrease in the fraction of molecules in the T state from 1 to 0.65. In the absence of inositol hexaphosphate the pH dependence of this fraction has a midpoint at 7.8, addition of inositol hexaphosphate shifts this midpoint by 1.5 units toward high pH. From the analysis of the data obtained and the pH dependences of functional properties (Tan, A.L., Noble, R.W. and Gibson, Q.H. (1973) J. Biol. Chem. 248, 2880-2888) the parameters of the two state model of cooperativity for carp hemoglobin were estimated.

The kinetics of the reduction of cytochrome c by the superoxide anion radical.
1. At neutral pH ferricytochrome c is reduced by the superoxide anion radical (O2-), without loss of enzymatic activity, by a second order process in which no intermediates are observed. The yield of ferrocytochrome c (82-104%), as related to the amount of O2- produced, is slightly dependent on the concentration of sodium formate in the matrix solution. 2. The reaction (k1 equals (1.1+/-0.1) - 10(6) M-1 - s-1 at pH 7.2, I equals 4 mM and 21 degrees C) can be inhibited by superoxide dismutase and trace amounts of copper ions. The inhibition by copper ions is removed by EDTA without interference in the O2- reduction reaction. 3. The second-order rate constant for the reaction of O2- with ferricytochrome c depends on the pH of the matrix solution, decreasing rapidly at pH greater than 8. The dependence of the rate constant on the pH can be explained by assuming that only the neutral form of ferricytochrome c reacts with O2- and that the alkaline form of the hemoprotein is unreactive. From studies at pH 8.9, the rate for the transition from the alkaline to the neutral form of ferricytochrome c can be estimated to be 0.3 s-1 (at 21 degrees C and I equals 4 mM). 4. The second-order rate constant for the reaction of O2- with ferricytochrome c is also dependent on the ionic strength of the medium. From a plot of log k1 versus I1/2-(I + alphaI1/2)-1 we determined the effective charge on the ferricytochrome c molecule as +6.3 and the rate constant at I equals 0 as (3.1+/-0.1) - 10(6) M-1 - s-1 (pH 7.1, 21 degrees C). 5. The possibility that singlet oxygen is formed as a product of the reaction of O2- with ferricytochrome c can be ruled out on thermodynamic grounds.

Algal glyceraldehyde-3-phosphate dehydrogenases. Conversion of the NADH-linked enzyme of Scenedesmus obliquus into a form which preferentially uses NADPH as coenzyme.
Scenedesmus obliquus contains two glyceraldehyde-3-phosphate dehydrogenases (EC 1.2.1.-) one of which uses NADH as its preferred coenzyme (D-enzyme) and the other NADPH (T-enzyme). On incubation of the D-enzyme with cysteine and a 1,3-diphosphoglycerate-generating system the specific activity with NADH as coenzyme decreased whilst that with NADPH increased by a factor of 10. The components of the generating system had no effect on the D-enzyme individually and it is concluded that 1,3-diphosphoglycerate was probably responsible for the change in nucleotide specificity. The coenzyme specificity of the T-enzyme was not affected by such treatment. A similar type of activation occurred to a lesser extent on incubation of the D-enzyme with 2,3-diphosphoglycerate. The NADPH-dependent activity of the D-enzyme could also be promoted by incubation with NADPH. However, in this case the activation was less than that seen with either 1,3- or 2,3-diphosphoglycerate. The change in coenzyme specificity of the D-enzyme occurred in parallel with changes in sedimentation behaviour. Initially, a single boundary of S20,w equals 14.5 S was present, but on conversion to NADPH-dependent activity by incubation with the 1,3-diphosphoglycerate-generating system, new boundaries of 7.5 S and 5.5 S appeared. The first of these corresponds in sedimentation coefficient to the native T-enzyme. On removal of 1,3-diphosphoglycerate the 7.5 S boundary disappeared accompanied by an increase in that of 14.5 S, whilst the 5.5 S boundary persisted. These changes are consistent with the reversible conversion of the D-enzyme into a form similar to the native T-enzyme in response to cysteine and 1,3-diphosphoglycerate. These effects may be explained if acylation of the active site of the D-enzyme by 1,3-diphosphoglycerate results in displacement of the bound nucleotide, thus promoting nucleotide exchange. These findings are consistent with the kinetic mechanism established for other glyceraldehyde-3-phosphate dehydrogenases. Similar activation was seen in extracts of other species of the Chlorophyta but not in other photosynthetic organisms. The significance of this type of activation of enzyme activity to the metabolism of these species of algae is discussed.

The uptake of choline by rat liver mitochondria.
1. Rat liver mitochondria can accumulate choline against a concentration gradient. Maximally about 30 nmol choline per mg mitochondrial protein are found in the matrix space. 2. The process of choline uptake is biphasic. After a rapid uptake of 1.5-15 nmol per mg protein, a slower uptake occurs if an energy supply is present. In the absence of energy, only the rapid uptake is found. 3. The inhibition of uncoupler-stimulated choline oxidation by cations is the result of an inhibition of choline uptake.

3alpha-, 7alpha- and 12alpha-hydroxysteroid dehydrogenase activities from Clostridium perfringens.
25 strains of Clostridium perfringens were screened for hydroxysteroid dehydrogenase activity; 19 contained NADP-dependent 3alpha-hydroxysteroid dehydrogenase and eight contained NAD-dependent 12alpha-hydroxysteroid dehydrogenase active against conjugated and unconjugated bile salts. All strains containing 12alpha-hydroxysteroid dehydrogenase also contained 3alpha-hydroxysteroid dehydrogenase although 12alpha-hydroxysteroid dehydrogenase was invariably in lesser quantity than the 3alpha-hydroxysteroid dehydrogenase. In addition, 7alpha-hydroxysteroid dehydrogenase activity was evident only when 3alpha, 7alpha, 12alpha-trihydroxy-5beta-cholanoate was substrate but notably absent when 3alpha, 7alpha-dihydroxy-5beta-cholanoate was substrate. The oxidation product 12alpha-hydroxy-3, 7-diketo-5beta-cholanoate is rapidly further degraded to an unknown compound devoid of either 3alpha- or 7alpha-OH groups. Group specificity of these enzymes was confirmed by thin-layer chromatography studies of the oxidation products. These enzyme systems appear to be constitutive rather than inducible. In contrast to C. perfringens. Clostridium paraputrificum (five strains tested) contained no measurable hydroxysteroid dehydrogenase activity. pH studies of the C. perfringens enzymes revealed a sharp pH optimum at pH 11.3 and 10.5 for the 3alpha-OH- and 12alpha-OH-oriented activities, respectively. Kinetic studies gave Km estimates of approx. 5 X 10(-5) and 8 X 10(-4) M with 3alpha, 7a-dihydroxy-5beta-cholanoate and 3alpha, 12alpha-dihydroxy-5beta-cholanoate as substrates for two respective enzymes. 3alpha-hydroxysteroid dehydrogenase was active against 3alpha-OH-containing steroids such as androsterone regardless of the sterochemistry of the 5H (Both A/B cis and A/B trans steroides were substrates). There was no activity against 3beta-OH-containing steroids. The 3alpha- and 12alpha-hydroxysteroid dehydrogenase activities, although differing in cofactor requirements cannot be distinguished by their appearance in the growth curve, their mobility on disc gel electrophoresis, elution volume on passage through Sephadex G-200 or heat inactivation studies.

Studies on phosphatidylinositol phosphodiesterase (phospholipase C type) of Bacillus cereus. I. purification, properties and phosphatase-releasing activity.
A phosphatidylinositol phosphodiesterase from the culture broth of Bacillus cereus, was purified to a homogeneous state as indicated by polyacrylamide gel electrophoresis, by ammonium sulfate precipitation and chromatography with DEAE-cellulose and CM-Sephadex. The enzyme (molecular weight: 29000 +/- 1000) was maximally active at pH 7.2-7.5, AND NOT INFLUENCED BY EDTA, ophenanthroline, monoiodoacetate, p-chloromercuribenzoate or reduced glutathione. The enzyme specifically hydrolyzed phosphatidylinositol, but did not act on phosphatidylcholine, phosphatidylethanolamine and sphingomyelin, under the conditions examined. The products from phosphatidylinositol of enzyme reaction were diacylglycerols and a mixture of myoinositol 1- and 1, 2-cyclic phosphates, suggesting that the enzyme was a phosphatidylinositol-specific phospholipase C. The enzyme released alkaline phosphatase quantitatively from rat kidney slices. A kinetic analysis was made on the release of alkaline phosphatase. The results suggest that phosphatidylinositol-specific phospholipase C can specifically act on plasma membrane of rat kidney slices.

Properties of triacylglycerol lipase in a mitochondrial fraction from baker's yeast (Saccharomyces cerevisiae).
A triacylglycerol lipase in a mitochondrial fraction isolated from yeast (Saccharomyces cerevisiae) has been characterized and the hydrolysis studied kinetically using an insoluble artificial triacylglycerol suspension. 1. The triacylglycerol was hydrolyzed almost completely to fatty acids and glycerol. The lipase activity was inhibited by potassium fluoride and the sodium salts of -chloride, -glycocholate and -pyrophosphate as well as by protamine sulfate but at concentrations much too high to indicate that the lipase is a non specific esterase or a lipoprotein lipase. Also parachloromercuribenzoate inhibited the lipase activity. Inhibitory effect of fatty acid was observed at concentrations above 1mM. This inhibition may provide a regulatory mechanism of the lipase in vivo. 2. On the day of isolation the lipase activity of intact mitochondria at pH 7.5 and 30 degrees C was 400 nmol free fatty acid -h-1 - mg-1 at a triacylglycerol concentration of 9.0 mM. Sonication of the mitochondria increased the activity 2-3 fold. Freezing of the mitochondria also activated the lipase and this activation was dependent upon the freezing method, the concentration of mitochondrial protein and the presence of bovine serum albumin. 3. The particulate nature of the assay system was illustrated by the observation that the apparent Km value of the lipase increased with the concentration of mitochondrial protein. For each protein concentration the lipase had two apparent Km values when the activity was assayed with intact mitochondria, but only one when assayed with submitochondrial particles. At the same protein concentration the Km value for the latter was identical with the "low affinity" Km for the lipase in intact mitochondria.

Properties of microsomal phospholipases in rat liver and hepatoma.
Phospholipase A1, A2 and lysophospholipase activities in microsomes of Novikoff hepatoma host rat liver and regenerating rat liver were compared using 1-[9', 10'-3H2]palmitoyl-2-[1'-14C] linoleoyl-sn-glycero-3-phosphoethanolamine, 1-[1' -3H-]hexadecyl-2-acyl-sn-glycero-3-phosphoethanolamine, and 1-[9', 10'-3H2]palmitoyl-sn-glycero-3-phosphoethanolamine as substrates. 1. Microsomes of all three tissues showed two pH dependent peaks of hydrolytic activity, one at pH 7.5 and another at pH 9.5. 2. Phospholipid hydrolytic activity in microsomes from host liver and regenerating liver require Ca2+ for hydrolysis at pH 9.5, but not at pH 7.5. Hepatoma microsomes require Ca2+ for activity at both pH values. 3. Phospholipase A1 activity, stimulated by addition of Triton X-100 to the incubation mixtures, was detected in both host liver and regenerating liver microsomes. There was no evidence of phospholipase A1 activity in hepatoma microsomes. 4. Phospholipase A2 was detected in microsomes of all three tissues using 1-[1'-3H] hexadecyl-2-acyl-sn-glycero-3-phosphoethanolamine as a substrate. The activity required calcium and was inhibited by Triton X-100. 5. Lysophospholipase activity was evident in the microsomes from all three tissues. The activity was inhibited by both Ca2+ and Triton X-100. 6. Differences were also detected between host liver and hepatoma microsomal phospholipid hydrolase activities with respect to the effect of increasing protein concentration, apparent Michaelis-Menten constants, and time course of the reaction.

Purification and positional specificity of sn-glycerol-3-phosphate acyltransferase from Escherichia coli membranes.
SN-Glycerol-3-phosphate acyltransferase was solubilized from membranes of Escherichia coli B and K-12 and purified on an affinity column of Sepharose 4B coupled with 6-phosphogluconic acid. Phosphatidylglycerol was required for activation and stabilization of the purified enzyme. The acyl residues were exclusively transferred to the position 1 of sn-glycerol 3-phosphate by the enzyme, regardless of whether the acyl-CoA was saturated or unsaturated.

Isolation and characterization of aldose reductase from calf brain.
Aldose reductase activity (alditol: NADP+ 1-oxidoreductase, EC 1.1.1.21) from calf brain was separated into two protein fractions by DEAE chromatography. Further purifcation by molecular sieve chromotography and electrofocusing yielding two distinctive enzymes, which were designated AR I and AR II. AR I was purified 646-fold and found to have an isoelectric point of 6.18. AR I was most active as a monomer with a molecular weight of 29 000 and appeared to be in equilibrium with a less active dimer. AR II was purified 425-fold and found to have an isoelectric point of 4.88. The molecular weight of this enzyme was 30 000. Although both enzymes had specificity for aldoses as substrates, AR I had two to three times larger turnover numbers with aromatic aldehydes and hexonates than did AR II. AR I was activated by sulfhydryl compounds and exhibited biphasic double reciprocal plots. AR I was more sensitive to inhibition by high substrate and phenobarbital concentrations than was AR II. AR I and AR II did not have antigenic similarity as tested by Ouchterlony immunodiffusion and counter immunoelectrophoresis. An immunochemical cross-reaction was observed between AR II and lens aldose reductase.

Studies on the role of methionine in porcine pancreatic phospholipase A2.
The unique methionine-15 residue located at the N-terminal site of iso- or beta-phospholipase A2 from porcine pancrease has been specifically carboxymethylated with iodoacetic acid. The modification results in a complete inactivation of the enzymatic activity toward micellar and monomeric substrates. Spectroscopic measurements reveled that the carboxymethylated protein still binds Ca2+ and monomeric substrates with comparable affinities as the native enzyeme. The active site histidine-54 residue in the modified enzyme shows a reactivity toward the active site-directed irreversible inhibitor p-bromophenacylbromide which is identical to that of the native enzyme. The alkylated protein, however, has lost its ability to bind to lipid-water interfaces. Although circular dichroic spectra of the carboxymethylated enzyme display some changes in the tertiary structure as compared with the native enzyme, the alpha-helix content remains rather constant. It is concluded that carboxymethylation of methionine-15 destroys the interface recognition site but has only limited influence on the active site of the molecule. Therefore, it seems that methionine-15 is not involved in the catalytic events but that this residue is part of the interface recognition site which embraces the N-terminal hydrophobic part of the enzyme: Ala-Leu-Trp-Gln-Phe-Arg-Ser-Met.

The effect of calcium ions on the hydrolysis of benzoylarginine ethyl ester by porcine enteropeptidase.
Calcium ions are shown to have a marked pH-dependent effect on the kinetics of benzoyllarginine ethyl ester hydrolysis by porcine enteropeptidase (EC 3.4.21.9). Below pH 6.0, calcium ions stimulate benzoylarginine ethyl ester hydrolysis but inhibit this activity above pH 6.0. This effect is mainly on the Km for benzoylarginine ethyl ester. At pH 5.3, 2mM calcium ions reduce the Km for benzoylarginine ethyl ester from 0.31 mM to 0.26 mM while at pH 6.5 the Km increases four-fold from 0.035 mM to 0.12 mM in the presence of calcium ions. Enteropeptidase activity is not inhibited by ethylenediaminetetra-acetate indicating that calcium ions are a non-essential cofactor for benzoylarginine ethyl ester hydrolysis.

Purification and characterization of bile salt hydrolase from Bacteroides fragilis subsp. fragilis.
A high-molecular-weight (250 000) bile salt hydrolase (cholylglycine hydrolase, EC 3.5.-.-) was isolated and purified 128-fold from the "spheroplast lysate" fraction prepared from Bacteroids fragilis subsp. fragilis ATCC 25285. The intact enzyme had a molecular weight of approx. 250 000 as determined by gel infiltration chromatography. One major protein band, corresponding to a molecular weight of 32 500, was observed on 7% sodium dodecyl sulfate polyacrylamide gel electrophoresis of pooled fractions from DEAE-cellulose column chromatography (128-fold purified). The pH optimum for the 64-fold purified enzyme isolated from Bio-Gel A 1.5 M chromatography was 4.2 and bile salt hydrolase activity measured in intact cell suspensions had a pH optimum of 4.5. Substrate specificity studies indicated that taurine and glycine conjugates of cholic acid, chenodeoxycholic acid and deoxycholic acid were readily hydrolyzed; however, lithocholic acid conjugates were not hydrolyzed. Substrate saturation kinetics were biphasic with an intermediate plateau (0.2--0.3 mM) and a complete loss of enzymatic activity was observed at high concentration for certain substrates. The presence or absence of 7-alpha-hydroxysteroid dehydrogenase was absolutely correlated with that of bile salt hydrolase activity in six to ten strains and subspecies of B. fragilis.

On the partial reactivation of inactivated pantothenase from Pseudomonas fluorescens.
Partial reactivation of inactivated pantothenase (pantothenate amidohydrolase, EC 3.5.1.22) from Pseudomonas fluorescens was studied. After partial inactivation during storing, pantothenase activity is increased by 10-40% when incubated with, for instance, oxalate, oxaloacetate or pyruvate. Reactivation proceedes slowly; with oxaloacetate the stable level of enzyme activity is attained in 20-30 min. The same compounds also cause reactivation of thermally inactivated pantothenase when partial inactivation has occurred at 28-37 degrees C. The amount of the reactivating enzyme form is relatively greater the lower the temperature during inactivation, but it never exceeds 20% of the original amount of active enzyme. Also another, unstable form of pantothenase is formed in thermal inactivation. This form becomes inactivated in a few minutes after the heat treatment, at pH 6-8 and at temperatures between 0 and 10 degrees C. Reactivation causes special problems in enzyme kinetic measurements; for instance, curvature is found in the lines of Ki determination by the Dixon plot.

Studies on aspartase. III. Alteration of enzymatic properties upon trypsin-mediated activation.
Highly purified aspartase (L-aspartate ammonia-lyase, EC 4.3.1.1) from Escherichia coli, already of full activity, is further activated 3.3-fold by limited treatment with trypsin. The activation requires a few minutes to attain maximum level, and hereafter the activity gradually decreases to complete inactivation. Prior or intermediate addition of soybean trypsin inhibitor results in an immediate cessation of any further change in the enzyme activity. Upon trypsin-mediated activation no appreciable change is detected in the molecular weight of the enzyme subunits as judged from sodium dodecyl sulfate polyacrylamide gel electrophoresis, nor in the pH vs. activity profile in the presence of added metal ions. However, S0.5 and hill coefficient for L-aspartate considerably increase upon activation. As the trypsin-mediated activation proceeds, a marked absorbance difference spectrum of the trypsin-treated aspartase vs. untreated aspartase appears with negative absorbance maxima at 278 and 285 nm. When the trypsin-activated enzyme is denatured in 4 M guanidine-HCl, followed by removal of the denaturant by dilution, the enzyme activity is readily restored to as much as 1.5 times that of the native enzyme, indicating that the trypsin-activated enzyme is rather a stable molecule.

Investigations on the kinetic properties of estrone glucuronyltransferase from pig kidney.
The microsomal fraction of the pig kidney catalyzes the glucuronidation of estrone in the presence of UDP-glucuronic acid. This bireactant system exhibits a sequential type of reaction mechanism. Increasing concentrations of either substrate increase the affinity of the enzyme for the other substrate. The Hill coefficient, n, was calculated to be 1.0 for both estrone and UDP-glucuronic acid. The Kestrone and KUDP-glucuronic acid are 6.6 muM and 254 muM, respectively. The estrone glucuronyltransferase (UDP-glucuronate: 17 beta-oestradiol 3-glucuronosyltransferase, EC 2.4.1.59) exhibits high substrate specificity in that it is inhibited noncompetetively by estradiol-17 beta, estradiol-17 alpha, estriol, testosterone, phenolphthalein and bilirubin; p-nitrophenol and o-aminophenol do not inhibit the glucuronidation of estrone. Mg2+ and Ca2+ were found to be nonessential activators. One of the two products of the reaction, estrone glucuronide, inhibits the enzyme competitively in the presence of increasing concentrations of UDP-glucuronic acid. The other product of the reaction, UDP, inhibits the enzyme noncompetitively with varying estrone concentrations and uncompetitively with varying UDP-glucuronic acid concentrations. Under incubation conditions for the glucuronidation of estrone, the enzyme catalyzes the reverse reaction with estrone glucuronide and UDP as reactants to an extent of about 0.4% of the forward reaction; this reverse reaction is also of a sequential type.

Interactions between phospholipids and barbiturates.
The effects of a number of barbiturates on the temperature of the lipid phase transition have been studied using chlorophyll a as a fluorescence probe. The barbiturates cause a reduction in the temperature of the phase transitions of dipalmitoyl phosphatidylcholine and dipalmitoyl phosphatidylethanolamine, the effects being greatest at lower pH values where more of the barbiturate is present in the uncharged form. There was no significant interaction between the barbiturates and dipalmitoyl phosphatidylserine. These and other observations on the actions of local anaesthetics are used to develop a model for local anaesthesia. It is suggested that the sodium channel is surrounded by an annulus of lipid in the gel state, this rigid microenvironment preventing the sodium channel relaxing from its active configuration to an inactive one. Local anaesthetics, which reduce the temperature of lipid phase transitions, trigger a change of the annular lipid from the gel to the liquid-crystalline state, with a consequent relaxation of the sodium channel to an inactive configuration, in which the sodium current is reduced or blocked.

Transport and phosphorylation of D-galactose in renal cortical cells.
An improved analytical procedure for the extraction and determination of total, free and phosphorylated tissue sugar is described. This method, employing ZnSO4 plus Ba(OH)2 for the precipitation of sugar phosphates, yields values identical with those obtained by the more laborious separation of free and phosphorylated sugar by ion-exchange chromatography. Erroneous values for free sugar due to the action of a Zn2+ -activated phosphatase and/or the lability to acids of some sugar phosphates, are avoided. Using this technique for the sudy of transport and phosphorylation of D-galactose in rabbit renal cortical slices and tissue extracts, it was found: 1. The cellular uptake of D-galactose was associated with the appearance of both free and phosphorylated sugar whether or not external Na+ was present. At 1 mM sugar, galactose was accumulated in the cells against a modest concentration gradient of 1.445 +/- 0.097 (n = 17). Galactose phosphate appeared in the cells considerably faster than free sugar under conditions of net uptake as well as of steady-state exchange (pulse-labelling). 2. Increasing saline pH (6-8) increased the cellular levels of sugar phosphate without affecting the steady-state values of free sugar. With tissue extracts, increasing pH also stimulated the activity of galactokinase and the dephosphorylation of galactose 1-phosphate by a Zn2+ -activated phosphatase. 3. 0.5 mM phlorizin inhibited the tissue uptake of galactose and its subsequent oxidation to CO2 only to a minor degree (30 and 10%, respectively). The absence of external Na+ further depressed the phlorizin effect. Preincubation of the tissue with phlorizin and subsequent washing in part abolished the inhibitory effect. The data suggest that a major portion of the galactose uptake by the tissue proceeds by a mechanism with a low affinity for phlorizin. 4. Efflux studies showed that the wash-out of free galactose from slices was associated with a net decrease of both free and phosphorylated tissue sugar. 5. The above results suggest the possibility that phosphorylation may represent a step in the Na+ -independent, phloretin-sensitive transfer of D-galactose across the antiluminal cell membrane. The participation of intracellular galactokinase and a Zn2+ -activated alkaline phosphatase in the maintenance of the steady state of free and phosphorylated galactose in the cells has been demonstrated.

Efflux studies showed that the wash-out of free galactose from slices was associated with a net decrease of both free and phosphorylated tissue sugar. 5. The above results suggest the possibility that phosphorylation may represent a step in the Na+ -independent, phloretin-sensitive transfer of D-galactose across the antiluminal cell membrane. The participation of intracellular galactokinase and a Zn2+ -activated alkaline phosphatase in the maintenance of the steady state of free and phosphorylated galactose in the cells has been demonstrated.

Transport and phosphorylation of 2-deoxy-D-galactase in renal cortical cells.
The transport and phosphorylation of 2-deoxy-D-[3H]galactose in rabbit renal cortical cells was studied. 1. The uptake of 2-deoxy-galactose by cortical slices is associated with an appearance of both free and phosphorylated sugar in the cells. At 1 mM external sugar the cells establish a steady-state gradient of free 2-deoxy-galactose of 3.97 +/- 0.15 (23 animals). 2. The acid-labile sugar phosphate accumulated in the tissue has been identified by a combination of paper and radio-chromatography, as well as on the basis of some of its chemical properties, as 2-deoxy-D-galactose 1-phosphate. Ice-cold trichloroacetic acid produces a decomposition of this compound. 3. Increasing external pH (6-8) brings about a decrease in the steady-state levels of both free and phosphorylated sugar in slices. On the other hand, increasing pH activates the phosphorylation of 2-deoxy-D-galactose by a crude kinase in a tissue extract. 4. Sugar phosphate accumulated in the cells is dephosphorylated by the action of a Zn2+ -activated phosphatase. 5. The efflux of 2-deoxy-D-galactose from the cells is rather slow compared with that found for D-galactose. The efflux is associated with some dephosphorylation of cellular sugar phosphate, and some loss of 2-deoxy-galactose phosphate into the wash-out medium takes place. 6. An inhibition analysis of the uptake of 2-deoxy-D-galactose by the slices indicates that the transport site is shared by D-galactose. The following points of interaction between the sugar molecule and the carrier are identified: C1-OH, C3-OH and C4-OH (both axial) and C6-OH. A (pyranose) ring structure is also essential. A close packing between the substrate and the carrier in the vicinity of C2 is indicated. 7. The data suggest that the above transport system is localized predominantly at the antiluminal (basolateral) face of the renal tubular cells. While the detailed mechanism of the actual transport step (i.e. active transport of the free sugar, or by the action of a phosphotransferase) is still unclear, the data present evidence that both galactokinase and a Zn2+ -activated phosphatase participate in the maintenance of an intracellular steady state of the transported sugar.

Heterogeneity of histidine transport in the Ehrlich cell.
We have reexamined the heterogeneity shown by histidine in its uptake by the Ehrlich ascites tumor cell, in the face of a contradiction of our earlier interpretation. We again find the fraction of histidine uptake at neutral pH inhibitable by the model substrate for System A, 2-(methylamino)-isobutyric acid, to be fully dependent on the presence of Na+ or Li+. The small Na+ -independent component not attributable to System L can be identified with System Ly+ through its inhibitability by homoarginine. This component increases as the pH is lowered with an apparent pK' a of 6.1. The simultaneous decrease in the uptake by the neutral systems could be identified, for System L, with the same titration of histidine to its cationic form, but for System A the sharp decrease is identified with the protonation of a structure on the membrane rather than one on the substrate. The action of H+ in the latter case proved approximately non-competitive with Na+ when tested with ordinary substrates.

Calcium incorporation by smooth muscle microsomes.
The purpose of the present work was to study the factors influencing calcium incorporation into a microsomal fraction prepared from the longitudinal smooth muscle of the guinea-pig ileum. Calcium incorporation required the presence of both ATP and Mg2+ and was unaffected by azide. It was enhanced by oxalate; this effect was pH dependent and it was maximal at pH 6.6. The relation between calcium uptake with oxalate and free Ca2+ concentration in the medium was represented by a curve with an optimum for Ca2+ equal to 3-10-5 M. The threshold concentration was comprised between 5-10-7 and 10-6 7. The optimum calcium uptake rate was 4.5 nmol Ca2+/mg protein per min. In the absence of oxalate, two distinct groups of binding sites were identified. Low affinity sites had a binding constant of 7-104 M-1 and a maximum binding capacity of 0.6-106 M-1 and a binding capacity of 33 nmol Ca2+/mg protein; their capacity was sensitive to pH changes. In the absence of oxalate, Ca2+ binding was depressed by Na+ with respect to K+ or choline. When the medium was supplemented with oxalate, the stimulation of 45Ca incorporation was barely detectable in the presence of choline+ and it was lower in a medium containing Na+ instead of K+. The subcellular distribution profiles of calcium incorporation with and without oxalate indicate the microsomal location of both activities. However, the oxalate-stimulated calcium uptake activity sedimented faster than the calcium binding activity. The subcellular distribution of marker enzyme actvities has been examined. The present results indicate that Ca2+ incorporations with and without oxalate are the result of two processes likely related to two different structures. The role of microsomal calcium uptake in excitation-contraction coupling and its modification by the activity of the sodium pump is discussed.

Alternating current studies of charge carrier transport in lipid bilayers. Pentachlorophenol in lecithin-cholesterol membranes.
Surface and interior electrical properties of lecithin-cholesterol bilayer membranes treated with the uncoupler pentachlorophenol have been determined on the basis of a.c. measurements over a wide range of frequencies (0.02 to 1000 kHZ). The method used depends on accurately determining the resistance of the aqueous solution in series with each individual membrane by extrapolating admittance data into infinite frequency. Loss tangent vs. frequency curves are corrected by subtracting out a loss contribution which is present in untreated membranes and is due, presumably, to dielectric relaxation. The results, which are useful below 100 kHZ, can be fitted to loss tangent curves computed for a three-element equivalent circuit consisting of frequency independent conductance-capacitance pairs, arranged in series to represent surface and interior properties of membranes. Interior conductances agree with net conductances obtained from d.c. measurements. The pH and concentration dependence of surface conductance is consistent with a scheme of transport in which a fixed number of surface binding sites are filled preferentially with neutral pentachlorophenol molecules, which in turn dissociate to supply protons to the aqueous phase. Surface capacitances range from 15 to 90 times that of interior capacitance and show a systematic increase with pentachlorophenol concentration at high pH, and a decrease with concentration at low pH.

The lasat mouse: a new model for transplantation of human tissues.
A new animal model characterized by hereditary athymia and asplenia was developed by breeding congenitally athymic with hereditarily asplenic mice. The new hybrids have no cellular immunity and produce significantly less antibody than nude mice. The lasat mouse has been found useful for the transplantation of normal and malignant hemopoietic cells and other neoplastic tissues of human origin.

The processing of human bone marrow for cryopreservation and reinfusion.
Bone marrow was aspirated from 22 patients with solid tumors. A median of 1.2 x 10(10) net bone marrow cells were obtained during a 1 hour 45 minute operative procedure. Three methods were used to concentrate the bone marrow for cryopreservation. The greatest concentration of mononuclear cells was obtained by the Haemonetics pheresis procedure. Bone marrow was cryopreserved in 10 % DMSO in volumes ranging from 150 to 700 ml. The thawed marrow was further processed to remove both DMSO and free hemoglobin prior to reinfusion. Cell clumping was observed in the first 6 of the 10 marrows thawed. Acidification of the thawed marrow to pH 6.65 was found to retard cell clumping. The immediate recovery of cells frozen was 66 % with a viability of 50 %. The mean number of viable mononuclear bone marrow cells per kilogram available for reinfusion was therefore 5.5 x 10(7).

[Induction of tyrosine aminotransferase by blastomogenic metabolites of tryptophan and tyrosine].
A comparitive study was made of the effect produced by endogenous blastomogenic agents (3-oxyanthranylic and paraoxphenyl-lactic acids) and their nonblastomogenic anaogues (anthranylic and phenyl-lactic acids) on the activity of tyrosine-aminotranspherase in the rat liver. Blastomogenic metabolites proved to be capable of inducing sharply the enzyme activity. This phenomenon and data on the role played by the increase in the activity of tyrosine-aminotranspherase and tryptophane-oxygenase in tyrosine and tryptophane catabolism on the way of a possible formation of blastomogenic metabolites permitted to put forward a suggestion on the "chain reaction" of accumulation of the endogenous blastomogenic agents in the organism.

[Effect of cocaine on the tyrosine hydroxylase of rat hypothalamus].
The influence of cocaine on tyrosine hydroxilase of rat brain hypothalamus was investigated in vivo (0.5 mg/kg) and in vitro (10(--6)--10(--5)M). Cocaine was used as a substance with a known adrenergic type of action. It was shown that under standard conditions cocaine in vitro increased the enzyme activity and decreased the Km for DMPH4 cofactor without changing Vmax of the reaction analyzed by the membrane enzyme. Cocaine in vitro decreased the tyrosine hydroxylase activity, especially that of the membrane enzyme. In this case there occurred a decrease of Km for DMPH4 and a decrease of Vmax of the reaction. The decrease of Vmax is considered to be the result of the secondary effect of cocaine.

[Analysis of the structure of the components of the convulsive action of corazole following administration of sulazepam and its metabolites to mice].
A study was made of the interrelationship between the minimal effective doses of pseudoclonic and clonico-tonic convulsions, and also tonic extension caused by the intravenous injection of corazol to mice and the effect of anticonvulsive action of sulazepam and its metabolites (diazepam, desmethyldiazepam and oxadiazepam) on this process. It was shown that all the compounds under study increased the values of the minimal effective doses by the recorded indices of the convulsive seizure, whereas the maximum of the anticonvulsive activity was reached 15 minutes after the sulazepam and oxazepam, and 5 to 30 min after diazepam administration. There proved to be a distinct correlation between the minimal effective doses values of the recorded indices of the confulsive seizure in the control animals which also persisted after the administration of the agents under study. It is supposed that sulazepam and its metabolites increased the minimal effective doses of corazol for the recorded effects, but failed to alter the general picture of the convulsive attack and did not influence the dispersion corazol dose-effect dependence.

[Participation of phytohemagglutinin-transformed mouse lymphocytes in development of the "graft-versus-host" reaction].
Transformed lymphocytes obtained as a result of phytohemagglutinin-stimulation of the cells of the lymph nodes of the CBA mice were incapable of realizing the graft-versus-host reaction in administration to the sublethally irradiated (CBAXC57BL/6) F1 hybrids. In this case the graft-versus-host reaction is induced by small untransformed lymphocytes with the same concentration of surface antigens detected by the antilymphocytic serum as in the intact lymphocytes.

[Suppression of interferon synthesis during the "graft-versus-host" reaction in F1(CBAXC57BL/6) mice].
The development of the graft-versus-host reaction (GVHR) in the F1(1CBA X C57BL/6 hybrid mice after the transplantation of spleen cells from the C57BL/6 parent donor resulted in a strong inhibition of the serum interferon production induced by the intraperitoneal injection of the Newcastle disease virus. In vitro with the mouse bone marrow cells during the development of the GVHR the interferon response was first reduced and then disappeared completely. The described phenomenon could therefore serve as an index of the development of the GVHR.

Analgesia produced by morphine when acting from the liquor space.
1 In cats analgesia was produced by morphine sulphate introduced into different parts of the liquor space in doses too small to be effective on intravenous injection. Analgesia was measured with the tail pinch method of Russell & Tate (1975). 2 On infusion into the fourth ventricle or into the subarachnoid space beneath the ventral surface of the brain stem caudal to the pons, doses of 100 to 200 mug of morphine sulphate were sufficient to produce strong long-lasting analgesia. On injection into the cisterna magna somewhat larger doses (400 to 800mug) were required. 3 It is concluded that the site where morphine acts when producing analgesia in all three circumstances is at the ventral surface of the brain stem. 4 The possibility is discussed that the structures acted upon are tryptaminergic nerve fibres. They arise from the raphe nuclei, belong to a descending inhibitory pathway, and on their way to the spinal cord, reach the ventral surface of the brain stem lateral to each pyramid, where they could be reached and acted upon by the morphine. This theory postulates a morphine sensitivity of tryptaminergic nerve fibres.

Behavioural treatment of orgasmic dysfunction: a controlled study.
Twenty-two anorgasmic women received 20 sessions of a multiple-technique behavioural therapy. The design included blind ratings by two independent assessors, multiple assessment instruments, and a waiting list control group. Treatment was significantly better than no treatment in terms of: (1) the percentage of patients experiencing orgasm during at least 50 per cent of sexual relations; (2) the percentage of women reporting satisfactory sexual relations at least 50 per cent of the time; (3) patients' ratings of positive reactions to various sexual behaviours; and (4) assessors' global clinical ratings. Significant improvement was also noted on the MMPI, IPAT, and Symptom Check List. Improvement was maintained at a follow-up average 9 months later. These results support the impression that a behavioural approach offers much promise in treating female orgasmic dysfunction.
Behavioural treatment of orgasmic dysfunction: a controlled study. Twenty-two anorgasmic women received 20 sessions of a multiple-technique behavioural therapy. The design included blind ratings by two independent assessors, multiple assessment instruments, and a waiting list control group. Treatment was significantly better than no treatment in terms of: (1) the percentage of patients experiencing orgasm during at least 50 per cent of sexual relations; (2) the percentage of women reporting satisfactory sexual relations at least 50 per cent of the time; (3) patients' ratings of positive reactions to various sexual behaviours; and (4) assessors' global clinical ratings. Significant improvement was also noted on the MMPI, IPAT, and Symptom Check List. Improvement was maintained at a follow-up average 9 months later. These results support the impression that a behavioural approach offers much promise in treating female orgasmic dysfunction.

The relationship of the serum gastrin and calcium concentrations in patients with multiple endocrine neoplasia type I.
The relationship between the serum gastrin and calcium concentrations has been examined in patients with multiple endocrine neoplasia type I. Variations in gastrin concentrations were induced by metiamide and secretin; calcium concentrations were altered by parathyroidectomy and by calcium infusion. Changes in the serum gastrin concentrations were not accompanied by changes in the serum calcium concentration. However, alteration of the serum calcium was accompanied by significant parallel changes in the serum gastrin. It is concluded that acute changes in the serum calcium may induce changes in the serum gastrin. Parathyroidectomy in these patients produced a fall in the serum gastrin, but the ability to produce large quantities of gastrin remains. It is postulated that the thyro-parathyroid hormones may modulate the relationship between calcium and gastrin.

Inhibitors of gastric secretion: current progress.
Several new compounds have become available recently which are potent inhibitors of gastric secretion. The therapeutic potential of these inhibitors in the peptic ulcer diathesis is reviewed and it is concluded that the histamine H2-receptor antagonists show most promise at present. The prostaglandins and gastro-intestinal polypeptides are of considerable physiological interest but are unlikely to have clinical importance in the immediate future.

Effect of surgical isolation of the hypothalamus on its neurotransmitter content.
The concentrations of norepinephrine, dopamine-beta-hydroxylase, dopamine, tyrosine hydroxylase, phenylethanolamine-N-methyltransferase, serotonin, tryptophan hydroxylase, histamine, glutamic acid decarboxylase, and choline acetyltransferase were determined in selected hypothalamic nuclei and in the median eminence after deafferentation of the medial basal hypothalamus. Norepinephrine and dopamine-beta-hydroxylase fell markedly while dopamine and tyrosine hydroxylase did not. Serotonin also decreased in all regions studied; histamine decreased in none. Choline acetyltransferase, phenylethanolamine-N-methyltransferase, and glutamic acid decarboxylase declined in some areas, but not in others.

Cardiac responsiveness to beta-adrenergic stimulation in experimental anemia.
Cardiac reactivity of beta-adrenergic stimulation was assessed by isoproterenol dose-reponse curves (dose range 0.025-0.4 mug/kg) before and 1 h after the rapid induction of anemia in dogs anesthetized with halothane:N2O:O2. Anemai (hematocrit = 16 +/- 4%) was induced by an isovolumic exchange transfusion with Dextran 70, and was followed by significant increments in cardiac output (+57 +/- 9%), max dP/dt of the left ventricle (+37 +/- 7%), and in peak acceleration of blood flow in the ascending aorta (+46 +/- 13%). Anemia was associated with a significant reduction of the chronotropic responses to all but the lowest dose of isoproterenol. The simultaneously determined inotropic responses (max dP/dt) where the same before and after the induction of anemia. The responses in terms of peak acceleration of aortic blood flow tended to be greater in the anemic than in the control phase, at all dose levels used. These findings indicate that in rapidly induced experimental anemia the heart is capable of responding to marked degrees of beta-adrenergic stimulation, representing a more than two-fold increase in the dP/dt.

Propranolol induces acute natriuresis by beta blockade and dopaminergic stimulation.
dl-Propranolol (0.8-1.6 mg/kg - h for 1 h) produced a transient two- to three-fold increase in sodium excretion in nondiuretic rats infused with Pitressin and aldosterone and in water diuretic rats. Sodium excretion increased more in rats depleted of renin by chronic Doca and salt administration than in rats maintained on a low salt diet. An angiotensin inhibitor (1,sarcosine-8,valine angiotensin II) decreased sodium excretion. Therefore the natriuresis was not mediated by antidiuretic hormone, aldosterone, or renin-angiotensin. d-Propranolol did not produce a natriuresis. Prior treatment with phenoxybenzamine did not prevent the natriuretic response but chlorisondamine pretreatment did. The natriuresis is produced by beta blockade and requires post ganglionic nerve function but is independent of alpha receptors. dl-Propranolol decreased heart rate and cardiac output but systemic pressure did not fall and renal blood flow increased. This suggests a dopamine-mediated renal vasodilation and natriuresis. Haloperidol and pimozide, both dopamine blocking agents with minimal beta blocking effects, prevented the natriuretic response. We conclude that propranolol may increase sodium excretion directly by blocking beta receptors in the distal nephron and indirectly by dopamine-mediated renal vasodilation.

Differences in the altered energy metabolism of hemorrhagic shock and hypoxemia.
The effect of hemorrhagic shock, hypoxemia, and anoxia on the levels of adenine and pyridine nucleotides of liver and kidney was assessed. ATP levels in liver and kidney of animals in shock or animals subjected to 7 min of anoxia decreased by 85 and 73%, respectively. Under hypoxic conditions (arterial PO2 AT 18 MMHg), the decrease was only 62 and 48% in liver and kidney, respectively. Tissue NAD levels decreased and NADH levels increased during shock but were found to be essentially unaltered during experimental hypoxemia. Thus, shock produced greater alterations in adenine and pyridine nucleotides than did hypoxemia alone, indicating that stagnant hypoxemia due to shock is more deleterious to energy metabolism than is severe hypoxemia with an otherwise normal circulation. The results also suggest that if an anterial PO2 OF 18 MMHg represents the initial stages of tissue hypoxia, then tissue ATP levels are a more sensitive indicator of this than NAD levels.

Reduction in brain tyrosine hydroxylase activity following acetylcholinesterase blockade in rats.
Activation of cholinergic neurons in the brain is produced by administration of the acetylcholinesterase inhibitors physostigmine and diisopropylfluorophosphate (DFP). This activation has a biphasic effect on tyrosine hydroxylase (EC 4.14.3-) activity. The acute effect of DFP, 1 mg/kg, intraperitoneally, or physostigmine, 0.2 mg/kg, intravenously, or 10 mug, intraventricularly, was a rapid reduction in tyrosine hydroxylase activity in the hypothalamus. The activities of DOPA decarboxylase (EC 4.1.1.28) and dopamine-beta-hydroxylase (EC 1.14.17.1) were not changed. In contrast to the acute effect, chronic administration of physostigmine, 0.2 mg/kg, intravenously, twice daily for 7 days produced an increase in tyrosine hydroxylase activity in the hypothalamus. The rapid acute effects may be due to an allosteric inactivation of tyrosine hydroxylase, while the chronic effects may reflect enzyme induction.

Reduced hemoglobin affinity for oxygen in venous blood following hemodilution, independent of changes in pH or PCO2.
A rapidly induced and readily reversible shift in the affinity of hemoglobin for oxygen has been demonstrated. The shift, similar to the Bohr effect, is independent of PCO2 or pH changes. It occurred within 30 min of hemodilution and was seen in portal venous blood but not arterial blood. A hypothesis is suggested involving a phasic alteration in levels of 2,3-diphosphoglycerate (DPG) or ATP binding to hemoglobin. It is proposed that, following hemodilution, the degree of these phosphates to hemoglobin increases on passage through the intestinal vascular bed. The increased DPG binding to hemoglobin results in displacement of additional oxygen. As the blood becomes reoxygenated, the levels of DPG-hemoglobin binding decline and DPG is displaced from the hemoglobin by oxygen.

Microdose mammography.
Tens of thousands of mammograms are performed daily in the United States. Accumulated radiation biologic data suggest that approximately 90-rad is the level of radition to the breast above which the incidence of cancer may be increase. A microdose system of roentgenography is described that provides better images at one-third to one-fifth the exposure of the commonly used low-dose system and about one-eight to one-tenth the dose of Xeromammography. This system should allow for repeated x-ray study in a patient as required, without exceeding the critical level.

An ESR study of the anchoring of spin-labeled stearic acid in lecithin multilayers.
In egg lecithin-water lamellar phases, spin-labeled stearic acid gives two superimposed ESR spectra which are only well resolved when the temperature is greater than 30 degrees C. These two spectral components are attributed to the dissociated and non-dissociated forms of the fatty acid carboxylic group, anchored at two different positions in the polar interface constituted by the hydrated lipid polar heads. Results on such interactions of other functional groups (spin-labeled fatty ester and fatty alcohol) are also presented.

[Guinea pig liver cytosol has an L-threonine deaminase activity distinct from L-serine deaminase].
Using sodium sulfate precipitation, "Sephadex G200" gel filtration and polyacrylamide gel electrophoresis, a L-threonine desaminase was demonstrated in the Guinea-Pig liver cytosol. This enzyme was separated from the guinea pig liver L-serine desaminase possessing an auxiliary activity on L-threonine substrate described by us in a previous work. The optimals for pH (7,1) and temperature (+ 55 degrees C) and the apparent molecular weight (134,000 + 20,000) were established.

Comparison of internal mammary artery and saphenous vein bypass grafts for myocardial revascularization: exercise test and angiographic correlations.
The effectiveness of myocardial perfusion with internal mammary artery (IMA) bypass revascularization has been questioned. We compared 37 patients with single patent IMA bypass grafts with 26 patients who had single patent saphenous vein graft (SVG) bypass. Serial computer assisted graded maximal stress testing was used for quantitation of palliation. Patients were classified and compared according to the completeness of revascularization by postoperative catheterization. All patient subgroups, had statistically significant improvements in work capacity, maximal heart rate, maximal rate-pressure products, abnormal exercise electrocardiograms, and exercise-induced angina pectoris. The quantitative improvements in these measurements of patient palliation were the same during postoperative stress tests after either SVG or IMA revascularization. Considering the overall higher patency rate of the IMA bypass, the data indicate that this procedure, when surgically applicable, is preferable to SVG bypass.

Renal acidification in hypothyroid man.
The role of thyroid hormone in renal hydrogen ion secretion remains largely unknown, and there is only limited information on renal acidification in hypothyroid patients. In the present study two of five adult male patients with untreated primary hypothyroidism and without clinical evidence of systemic autoimmune disease were unable to lower their urine pH appropriately after short duration acid-loading. Since, prior to acid-loading, their arterial blood gas values were within the normal range and urinary bicarbonate excretion was trival, the findings are consistent with the incomplete syndrome of distal renal tubular acidosis. Although the mechanism of this abnormality remains unknown, thyroxine deficiency per se may in part be responsible.

Group desensitization of dissimilar anxieties.
Group desensitization is an effective, efficient anxiety-reduction therapy that, nonetheless, is not applicable in most mental health settings. This paper outlines several procedural modifications that make possible the desensitization of diverse anxieties within a single group and thus make group desensitization a more practical strategy.

Effect of ascorbic acid on arylsulfatase A and B activities in human chondrocyte cultures.
Cultured normal human articular cartilage chondrocytes exhibited decreasing levels of arylsulfatase A and B activities when grown in the presence of increasing levels of ascorbic acid (0 to 90 mug/ml) in the media. That this was not a general effect on all lysosomal enzymes was supported by the increase in acid phosphatase activity and no change in beta-glucuronidase activity observed with increasing levels of vitamin C under identical culture conditions. No decrease in either arylsulfatase activity was observed when ascorbic acid was replaced by ascorbate-2-sulfate. Ascorbic acid did not inhibit either arylsulfatase activity when added directly to the assay mixture. These data, combined with results of mixing experiments, suggest that the effect of vitamin C is mediated through cellular factors produced in response to its inclusion in the growth media.

Enzymes from human articular cartilage: isolation of arylsulfatase B and its comparison with arylsulfatase A.
This study describes the isolation of arylsulfatases A and B (arylsulfate sulfohydrolase EC 3.1.6.1) from human articular cartilage. These enzymes were extracted from collagenase digests of tissue homogenates. After fractionation with ammonium sulfate the enzymes were separated from each other by DEAE-cellulose chromatography and further purified by gel filtration on Sephadex G-200. Sulfatase B, subsequently chromatographed on CM-cellulose was apparently homogenous as judged by polyacrylamide gel electrophoresis in the presence and absence of sodium dodecyl sulfate. The enzyme has a pH optimum of 5.6, a molecular weight of 51,000 and Km of 2.6 mM for 4-nitrocatechol sulfate. Sulfatase A was found to be a glycoprotein with a pH optimum of 4.8, a molecular weight of 105,000 and a Km of 0.16 mM for 4-nitrocatechol sulfate. The competitive inhibition of both enzymes by inorganic sulfate, sulfite and phosphate support the likelihood of a common reaction mechanism. In contrast to sulfatase B which showed minimal inhibition, sulfatase A was totally inhibited by 5 mM N-ethylmaleimide.

Lorazepam as a sedative-amnesic in an intensive care unit.
A clinical study was carried out to evaluate the usefulness of intravenous lorazepam, given for sedation instead of opiate narcotics or diazepam, in 25 seriously-ill patients being treated in a respiratory and intensive care unit. All but 3 patients were on assisted ventilation. Standard doses of 4 mg lorazepam were given at 4 or 6-hourly intervals for periods up to 25 days. ECG, haemodynamic stability and biological determinations were monitored constantly. Apart from some delay in onset of action, lorazepam proved to be a useful sedative with diminished recall on the part of the patients. No side-effects were reported, nor was there any local reaction to the injection. Cardiac output was measured in 9 patients following intravenous administration of a single-dose of either 4 mg or 8 mg lorazepam. No significant changes were recorded.

[Effective treatment of duodenal ulcer with cimetidine (author's transl)].
Twelve male duodenal ulcer in-patients received in a double-blind trial either the histamine H2-receptor antagonist cimetidine (4 X 200 mg/d p.o.) or placebo capsules. Ulcer sizes were assessed endoscopically before therapy followed by repeat endoscopy at weekly intervals. Duodenal ulcer healing was significantly more rapid in cimetidine-treated patients than in those receiving the placebo (chi2 test; P less than 0.0005). Plotting of log ulcer sizes (mm2) against time (days) resulted in regression lines the slopes of which indicated the respective half-time of ulcer healing: about 6 days on cimetidine therapy and about 20 days on placebo treatment. Gastric secretion of acid, protein, pepsin, and N-acetylneuraminic acid-containing glycoproteins was not altered by a 4-week course of daily cimetidine or placebo, nor pancreatic secretion of bicarbonate and enzymes. No statistically significant changes in laboratory findings (haemoglobin, white blood-cells, neutrophils, platelets, alkaline phosphatase, blood-urea, serum-creatinine, GOT, GPT) were associated with treatment.

[Treatment of diabetic coma and precoma with continuous low-dose insulin infusions (author's transl)].
13 patients, nine women and four men, aged 22 to 83 years, were treated for diabetic coma or precoma between September 1974 and January 1976. Ten patients were known diabetics and six of them had been treated with insulin. On admission blood sugar was 32.4 +/- 3.3 mmol/l (5.84 +/- 0.6 g/l). The capillary blood pH was 7.15 +/- 0.06 (n = 13). Treatment consisted of continuous insulin infusion (6 IU soluble insulin/hour), physiological saline, potassium substitution and sodium bicarbonate (if the pH was below 7.15). In the first hours of treatment 98 +/- 12IU of insulin, 6.5 +/- 0.5 litres of fluid, 168 +/- 22 mmol of potassium and 237 +/- 55 mmol NaHCO3 were required. During the first 4 hours of the insulin infusion the blood sugar decrease per hour was 3.55 mmol/l (0.64 g/l). Hypokalaemia during treatment occurred in one case, hypoglycaemia was not observed. A preceding treatment with insulin and severe acidosis did not influence therapeutic success. Twelve patients were treated successfully, one patient died 6 hours after admission following mesenteric arterial embolism.

Interaction of uteroglobin with progesterone, 5alphapregnane-3,20-dione and estrogens.
Uteroglobin was obtained from 5 day pregnant rabbits and purified to homogeneity by Sephadex G 75 and DEAE-cellulose chromatographies. Progesterone binding to uteroglobin was decreased by lyophilization and enhanced by SH-reducing agents. Dithiothreitol was more effective than dithioerythritol, and beta-mercaptoethanol was only active at 25 to 100 mM concentrations. SH-blocking agents (iodoacetate, iodoacetamide, phydroxymercuribenzoate and, dithiobisnitrobenzoic acid) inhibited binding. In the absence of SH-reducing agents only one in every 500 uteroglobin molecules bound the hormone, whereas under optimal conditions (20 mM dithiothreitol) one in every two molecules bound progesterone. There was no significant difference in equilibrium dissociation constants under these two conditions. Uteroglobin had a relatively high affinity for progesterone (KD=4.1 X 10(-7)M) but a threefold higher affinity for 5alpha-pregnane-3,20-dione (KD=1.3 X 10(-7)M). Estradiol was bound but non-specifically with a very low affinity, and its binding was not enhanced by SH-reducing agents. Hormonal specificity of binding to uteroglobin was different from that of binding to rabbit uterine progesterone receptor. Various synthetic progestagens (chlormadinone acetate, norethisterone, R5020) were bound to the latter but not to the former protein. Diethylstilbestrol had some affinity (15% of that of progesterone) for uteroglobin and no affinity for the progesterone receptor. Uteroglobin incubated in the presence or absence of cofactors (NADH and NADPH) with or without dithiothreitol did not metabolize progesterone.

Progesterone metabolism in vitro by rabbit testes at different stages of development.
Testicular homogenates from white rabbits of 0.4, 1, 3, 4, 5, 8, 18, and 24 months of age were incubated with [3H]progesterone and NADPH. At 12 days of age, major C21-17-OH-and C19- steroids formed from progesterone were 17alpha-hydroxyprogesterone and testosterone. However, at 4-24 months of age, 17alpha-hydroxyprogesterone, 3beta,17alpha-dihydroxy-5alpha-pregnan-20-one, and 5alpha-reduced C19-steroids such as 17beta-hydroxy-5alpha-androstan-3-one, 3beta-hydroxy-5alpha-androstan-17-one, and 5alpha-androstane-3beta,17beta-diol were the major products. The formation of significant quantities of 5alpha-reduced C19-steroids, which had been demonstrated previously only in prepubertal testes of rats and mice, was present in prepubertal as well as adult testes of rabbits. These findings clearly indicate that the metabolic patterns of progesterone in the adult rabbit differ from those in the adult rat and mouse. The major C19-steroids formed by testes are testosterone in the adult rat and mouse, but 5alpha-reduced C19-steroids in the adult rabbit.

Direct determination of ligand interactions with beta-adrenergic receptors on intact turkey erythrocytes: correlation of binding with biological activity.
Previous studies on the interaction of labeled beta-adrenergic blockers with beta-adrenergic receptors have employed broken cell or membrane preparations. We have now carried out direct binding analysis on intact turkey erythrocytes employing the potent, high specific activity blocker [125I]-hydroxbenzylpindolol (HYP). [125I]HYP binds to a single class of receptor sites with a K of 5.3 X 10(10)M-1 and a binding capacity of 400-500 sites/cell. These results as well as the kinetics of association and dissociation and lack of evidence for negative cooperativity all agree well with studies reported earlier on membrane preparations from the same cells. True dissociation constants (Kd) for agonists and antagonists determined by inhibition of binding of [125I]HYP are in good agreement with results in membrane preparations. These Kd's have been compared directly with activation or inhibition constants for effects on adenylate cyclase using generation of [14C]cAMP from [14C]adenine in intact cells. The close correlation between effects on binding and adenylate cyclase activity in whole cells are similar to results obtained in membrane preparations in the presence of guanine nucleotides, suggesting the presence of an analogous regulatory substance in vivo.
