    Notes: Summary Tolmesoxide is a new, direct-acting vasodilator drug for use in the management of both hypertension and cardiac failure. In 6 essential hypertensives inadequately controlled by combined β-blocker and diuretic therapy (average supine blood pressure 178/103 mm Hg) the addition of tolmesoxide (300–900 mg daily) was associated with a significant improvement in blood pressure control (average supine blood pressure 161/89 mmHg). The effect of food on the pharmacokinetics and pharmacodynamics of tolmesoxide have also been studied because, particularly at higher doses, the drug has been associated with upper gastrointestinal upset and it has been empirically recommended that it be taken with food. The blood pressure and heart rate responses were not significantly different when tolmesoxide was taken fasting or with food. Food resulted in a significant reduction in the peak plasma tolmesoxide concentration (2.14 µg/ml compared to 2.97 µg/ml) and a significant increase in the time to reach peak plasma concentration (1.67 h compared to 0.63 h). Although there was no impairment of its hypotensive effect, food significantly altered the pharmacokinetics of tolmesoxide and may therefore be useful in reducing the gastrointestinal disturbance associated with its use. In the treatment of inadequately controlled hypertension, tolmesoxide has a limited role as an alternative vasodilator.

    Notes: Summary The antihypertensive effect of labetalol (L) was compared with that of clonidine (C) in a randomized cross-over study in 17 hypertensive outpatients on bendrofluazide (B). After treatment for two weeks with B (5 mg qd), either L (100 mg tid) or C (0.1 mg tid) was given and their doses were titrated at 2-weekly visits until normotension was achieved, or intolerable side-effects occurred. The treatment with B and L or C was then continued in a cross-over fashion for two 6-week periods, with 3 week diuretic washouts and subsequent dose-titration periods between the treatment periods. At the end of B, the supine blood pressure (BP) was 156/101, and at the end of B + L and B + C it was 136/91 (p〈0.001) and 137/91 (p〈0.001), respectively, pooling the data from both periods. At the end of B, the standing BP was 155/115, and at the end of B + L and B + C 134/100 (p〈0.001) and 139/106 (p〈0.001), respectively. The mean daily doses required were L 476mg and C 0.335 mg. On a weight basis, labetalol had about 1/1400 of the potency of clonidine. 12 patients complained of tiredness and dry mouth on clonidine and 2 patients of unsteadiness on labetalol. Labetalol caused a psoriasiform rash on the hands in one patient and limb weakness in one patient.

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Prazosin is a post synaptic alpha adrenergic blocker effective in hypertension, whose hypotensive effect is unaccompanied by reflex tachycardia or hyperreninemia, nor by other evidence of increased sympathetic activity. We studied the baroreceptor reflex arc as a potential mediator of these effects. Twenty-two essential hypertensive men were treated with prazosin alone versus placebo, and experienced a blood pressure fall (from 114.8±3.6 down to 101.1±2.5 mm Hg,p〈0.005) unaccompanied by any change in heart rate, plasma renin activity, or several other indices of sympathetic nervous system activity (plasma dopamine-β-hydroxylase activity; urinary excretion of free catecholamines and vanillyl mandelic acid; allp〉0.1). Concomitant with the blood pressure fall, there was a significant depression of baroreflex arc sensitivity, from 11.4±2.0 ms/mmHg down to 6.6±1.9 ms/mmHg (p〈0.05), without an associated change in cardiac vagal inhibition (291.2±46.2 versus 300.3±19.2 ms,p〉0.1). Baroreflex arc sensitivity depression may in part explain the lack of reflex sympathetic outflow noted during prazosin treatment of hypertension.

    Notes: Summary A double-blind, cross-over study in 16 patients with essential hypertension was carried out, to evaluate any possible interference by indomethacin, a known prostaglandin-synthetase inhibitor, with the antihypertensive effect of oxprenolol, a non-selective beta-adrenoceptor blocking agent. Both indomethacin and oxprenolol, as well as the two drugs combined, inhibited plasma renin activity; no change was found in urinary sodium excretion or body weight. Oxprenolol alone caused a highly significant decrease in the systolic (−10.4 mmHg,p〈0.001), diastolic (−7.4 mmHg,p〈0.001) and mean (−7.7 mmHg,p〈0.01) blood pressures, whereas indomethacin did not influence blood pressure. When the two drugs were given in combination, blood pressure decreased (systolic: −5.9 mmHg; diastolic: −4.0 mmHg; mean: −4.6 mmHg), but the changes induced in blood pressure were reduced by about 50% when compared with those in the oxprenolol alone period. The data show that indomethacin seems to interfere with the antihypertensive effect of oxprenolol, by an action which may be due to the inhibition of prostaglandin synthesis.

    Notes: Summary The antihypertensive, saluretic and hypokalaemic effects of a small dose of cyclothiazide (2.5 mg daily) were compared with those of a conventional dose of an hydrochlorthiazide-amiloride hydrochloride combination (50+5 mg daily). Both preparations were given to 13 patients with mild (WHO I) hypertension in a cross-over manner for six weeks, with an intervening wash-out phase of three weeks. The antihypertensive efficacy of cyclothiazide was well comparable to that of the hydrochlorthiazide-amiloride combination, although cyclothiazide tended to inhibit renal sodium reabsorption less than the combination. Cyclothiazide tended to cause hypokalaemia, apparently due to increased potassium loss, but with the present dosage none of the 13 patients developed marked hypokalaemia (serum potassium less than 3.3 mmol/l). Both drugs led to a comparable increase in serum urate concentration. Neither of the preparations affected creatinine or free-water clearance. The results suggest that even in relatively small doses thiazides effectively decrease blood pressure, and combining thiazides with potassium-sparing diuretics is advantageous only in patients with marked hypokalaemia and its associated risks.

    Response of blood pressure and plasma norepinephrine to propranolol, metoprolol and clonidine during isometric and dynamic excercise in hypertensive patients (1982)

    Notes: Summary The effects of metropolol (beta1-selective), propranolol (nonselective) and clonidine (central alpha-stimulant) on plasma norepinephrine, blood pressure and heart rate were assessed at rest, during isometric work and dynamic exercise in 15 patients with moderate hypertension. Metroprolol resulted in a lower diastolic blood pressure during isometric and dynamic exercise than propranolol, which was paralleled by a lower plasma norepinephrine level during dynamic work; both beta-adrenergic blocking compounds resulted in a lower heart rate in all test situations than that obtained with clonidine; clonidine produced similar control of diastolic blood pressure to that obtained with the beta-adrenergic blocking agents, but did not clearly attenuate the systolic blood pressure response to dynamic exercise. Plasma norepinephrine concentrations tended to be lowest following clonidine, especially during dynamic work. The findings support the hypothesis that the central action of clonidine inhibits peripheral release of norepinephrine, but is insufficient to attenuate cardiac stimulation by physical exercise. The fact that propranolol caused higher plasma norepinephrine concentrations than metoprolol during exercise may explain the difference in the blood pressure responses during exercise.

    Notes: Summary 36 out of 52 patients with essential hypertension, whose blood pressure was not normalized with pindolol 15 mg per day, were treated with 30 mg per day for four to six weeks. Pindolol was administered in random order, either as 15 mg twice daily or as one 30 mg retard tablet once daily. Blood pressure was lowered from mean pretreatment levels of 174/111 mmHg to 149/98 mmHg by 15 mg b.d., and to 145/97 mmHg by 30 mg retard. In five patients diurnal variations in blood pressure and plasma pindolol levels were determined. At all times during the day blood pressure was at least as well controlled by 30 mg retard as by 15 mg b.d. Plasma concentration maxima were similar with both forms, but a higher concentration was maintained for a longer time after the retard tablet. Pindolol 30 mg was well tolerated and the incidence of side effects was lower than during treatment with 15 mg b.d. Thus, patients requiring high doses of pindolol for control of hypertension can safely and conveniently be treated with a single tablet of 30 mg pindolol retard.

    Notes: Summary The haemodynamic effect of Tolmesoxide, a new sulphoxide chemically dissimilar from other vasodilators, was investigated in eight patients with chronic heart failure subsequent to ischaemic heart disease and/or hypertension. Tolmesoxide significantly increased the cardiac output and reduced the indices of systemic vascular resistance, the mean pulmonary arterial pressure and left ventricular filling pressure in most patients studied. These changes were observed both as acute and chronic effects. No significant effect on the mean arterial pressure, heart rate or myocardial oxygen supply/demand was observed. Tolmesoxide appeared to be therapeutically potent by both intravenous and oral routes.

    Notes: Summary Parameters of the autonomic nervous system were studied in normotensive subjects (NT; standing blood pressure (BP)≤125/85 mmHg) and in subjects with borderline hypertension (BHT; 140/90≤standing BP〈60/100 mmHg). No differences in plasma noradrenaline and adrenaline levels were found between NT and BHT subjects, neither at rest nor during exercise at 75% of maximum work capacity. The dose of noradrenaline required to increase systolic BP by 10 mmHg was significantly higher in NT than in BHT subjects (5.13±0.42 vs 3.50±0.57 µg · min−1). No difference between NT and BHT subjects was found in the dose of isoprenaline required to increase heart rate by 20 beats · min−1 (1.21±0.12 vs 1.09±0.11 µg · min−1). Resting salivary flow was significantly lower in BHT than in NT subjects (0.39±0.06 vs 0.98±0.06 g · min−1), suggesting decreased parasympathetic activity in the former group. The enhanced pressor effect of noradrenaline, together with the decreased parasympathetic activity, could explain the elevated blood pressure and heart rate in subjects with borderline hypertension.

    Notes: Summary Bopindolol (LT 31-200), a new, long-acting, non-selective beta-blocker, was given as monotherapy to 13 patients, 12 with essential hypertension and 1 with renovascular hypertension. After a placebo period of 4–6 weeks, bopindolol was given once daily, starting with 1 mg and subsequently increasing at two-weekly intervals to 2 and 4 mg once daily until a diastolic blood pressure⩽90 mmHg was achieved. The effective dose was continued for 12 weeks. In 10 patients plasma levels of renin, noradrenaline, adrenaline and cholesterol were measured during placebo and after 3 months of therapy. Blood pressure and heart rate were lowered significantly during bopindolol treatment. The mean effective dose was 2.2 mg per day. In 10/13 patients a diastolic blood pressure⩽90 mmHg was achieved. Side effects were minimal. Changes in plasma noradrenaline and adrenaline were small and not significant, but renin and cholesterol were significantly reduced. Thus, LT 31-200 is an effective and well tolerated beta-blocker when given in a once daily dosage.

    Notes: Summary The antihypertensive effect of nifedipine during long-term therapy was investigated in 5 patients receiving nifedipine as the sole drug and in 10 patients who had nifedipine in combination with a beta-adrenoceptor blocking drug. Nifedipine monotherapy was problematic because of side-effects and development of resistance to therapy after a few months. In patients who received the combined therapy significant and stable blood pressure reductions were maintained during the whole observation period (12–33 months). However, the occurrence of peripheral oedema in 4 of the patients necessitated the addition of a thiazide diuretic. It is concluded that nifedipine is not a first choice drug for the long-term treatment of arterial hypertension. When given in addition to a beta-blocker it is well tolerated and powerful but fluid retention may occur and if not counteracted by a diuretic it will limit the antihypertensive potential of the drug.

    Notes: Summary The acute and long-term hypotensive effects of low doses of nifedipine, and the correlation between the fall in the blood pressure (BP) and the plasma nifedipine concentration, were investigated in patients with essential hypertension. The oral administration of nifedipine 5 mg rapidly decreased BP from 163±22/101±10 to 127±12/82±9 mmHg (mean±SD; p〈0.001), and increased heart rate from 72±8 to 76±6 beats/min (p〈0.05), plasma renin activity rose from 1.2±0.6 to 1.4±0.8 ng/ml/h (p〈0.05), and plasma nifedipine concentration was 75.6±22.0 ng/ml 30 min after administration (n=7). The nifedipine concentration was significantly correlated both with the fall in BP (r=0.410, p〈0.02, n=31) and the rise in the heart rate (r=0.412, p〈0.02, n=31). Treatment with nifedipine 5 mg t.d.s. alone or in combination either with propranolol 10 mg t.d.s., or thiazide 1 tablet daily, or propranolol and thiazide, controlled BP in 36 patients during the 22 week study period. During the long-term nifedipine therapy, the plasma nifedipine level was significantly correlated with the fall in systolic (r=0.577, p〈0.01, n=20) and diastolic (r=0.595, p〈0.01, n=20) BP. It was concluded that the plasma nifedipine concentration could be correlated with the fall in BP, and that low doses of nifedipine, either as monotherapy or in combination, were effective in the acute and long-term treatment of patients with essential hypertension.

    Notes: Summary Eighteen patients with mild impairment of renal function (glomerular filtration rate 65±5 ml/min: m±SEM) and hypertension (168/105±6/3 mmHg) were shown on average to have abnormally increased cardiovascular pressor responsiveness to infused norepinephrine (NE; p〈0.05), whereas plasma and urinary NE, exchangeable body sodium and blood-volume did not differ significantly from normal. A slightly increased pressor responsiveness to angiotensin II was associated with a tendency to low plasma renin activity (PRA). Compared to placebo conditions, treatment with the loop-diuretic muzolimine in a mean dose of 35±2 mg/day for six weeks decreased blood-pressure and exchangeable sodium (p〈0.05), and NE pressor responsiveness was restored to normal values, whilst plasma and urinary NE were not significantly changed. This was consistent with improvement of the initially abnormal relationship between NE levels and NE responsiveness factors. In contrast, the pressor dose of angiotensin II and PRA were increased to an approximatively similar extent during muzolimine treatment. These observations suggest that removal of body sodium and a decrease in NE reactivity without an equivalent increase in sympathetic nervous activity may be important complementary factors in the antihypertensive mechanisms of diuretic treatment in patients with mild renal functional impairment.

    Notes: Summary Prizidilol is a new antihypertensive agent reported to possess combined precapillary vasodilator and betareceptor-blocking properties. To clarify the profile of the acute effects of prizidilol in man, a variable dose study was performed in 8 patients with benign essential hypertension. Blood pressure, heart rate, plasma renin activity, aldosterone, plasma and urinary catecholamines and electrolytes were determined at short intervals before and up to 23 h after oral administration of placebo and prizidilol 150, 300 and 600 mg. The 4 studies were performed at weekly intervals according to a Latin square design. Prizidilol produced dose-dependent decreases in supine and upright blood pressure, with an initial change after about 2 h and maximal effects from 4 to 8 h after drug ingestion. Following a high dose of prizidilol, supine mean blood pressure (average 128 mmHg prior to treatment) was normalised (〈107 mmHg) from 3 to 7 h and was still below predose levels 23 h after ingestion. The only reported side effects were postural dizziness in 2 cases (corresponding to a fall in systolic upright blood pressure to 〈95 mmHg) and headache in one case. A biphasic variation in heart rate and plasma renin activity, with an early drop and a subsequent tendency to a slight rise, was observed after an intermediate or high dose of prizidilol. Plasma norepinephrine levels were increased by a high dose of prizidilol, while plasma epinephrine, aldosterone and plasma and urinary electrolytes were not consistently changed. Prizidilol in a single oral dose appeared to be a potent antihypertensive agent. The profile of heart rate and plasma renin point to early dominance of beta-blockade followed by appearance of the concomitant vasodilator properties of prizidilol.

    Notes: Summary Since there is only scanty, indirect information about the mechanism of the hypotensive effect of spironolactone, 9 patients with essential hypertension were studied according to a randomised double-blind, cross-over protocol. Spironolactone 100mg b.i.d. and placebo were each given for one month and the following parameters were studied: blood pressure, heart rate, response to cold pressure and hand-grip tests, as well as blood flow in the calf and finger vessels. Flow in the calf and fingers representing muscle and skin arteries, respectively, was measured semicontinuously with an ECG-triggered venous occlusion plethysmograph. After spironolactone there was a significant decrease in the systolic and diastolic blood pressures in the supine, sitting and standing positions; the sitting systolic and diastolic blood pressure decreased by (mean ± SE) 27±4mm Hg (p〈0.001) and 11±4mm Hg (p〈0.02), respectively. No orthostatic response was observed. Heart rate remained unchanged. Blood flow through muscle and skin vessels increased in 6 out of 9 patients, and in these patients calculated vascular resistance in these areas decreased. Spironolactone did not significantly change the response of systemic blood pressure to the handgrip and cold pressure tests. The present data confirm the hypotensive properties of spironolactone and show that this effect is associated with dilatation of muscle and skin arteries in many but not in all the patients. The data do not support the hypothesis that spironolactone decreases the responsiveness of systemic blood pressure to orthosympathetic stimulation.

    Notes: Summary Sixteen patients with essential hypertension completed a double blind factorial trial comparing the effects of indapamide (2.5 mg daily) and pindolol (10 mg daily) on blood pressure, heart rate, plasma renin activity and plasma aldosterone concentration. There were four randomised test phases of eight weeks each during which patients received indapamide alone, pindolol alone, indapamide plus pindolol and no active treatment (placebo). Blood pressure and heart rate were measured every two weeks. Supine mean arterial pressure fell from 117 mm Hg in the placebo phase to 111 mm Hg in the indapamide phase, 106 mm Hg in the pindolol phase and 103 mm Hg in the combined indapamide plus pindolol phase. Factorial analysis confirmed that the hypotensive effects of the two drugs were additive, without evidence of potentiation or antagonism. Indapamide caused significant reductions in plasma potassium and chloride, and increases in plasma bicarbonate and urate concentrations; it also caused increases in plasma renin activity and aldosterone concentration. These changes are similar to those observed with thiazide diuretics.

    Notes: Summary An open, observer-blind, therapeutic titration trial was carried out in 28 patients with mild or moderate essential hypertension to determine the effective dose range of nadolol given once a day. 11 patients became normotensive (supine diastolic blood pressure 90 mm Hg or below) with 80 mg, 4 with 120 mg and 1 with 160 mg. The largest step in the reduction of blood pressure was achieved with the first dose step of 80 mg, and only a small, non-significant further decrease was obtained with higher dose levels. Thus, nadolol, unlike propranolol, has a narrow effective dose range, and this should permit a brief dose adjustment period, which would be important in improving patient compliance.

    Notes: Summary The haemodynamic response and pharmacokinetics of single dose oral tolmesoxide were studied at various dose levels in 4 patients with severe hypertension. There was a reproducible fall in mean arterial pressure from baseline of 24.2% and a rise in heart rate of 37.6% following administration of tolmesoxide. The onset of antihypertensive action occurred within 1 h, with a peak effect at 3 h after dosing. The mean duration of action was up to 12.0 h. Tolmesoxide had a mean half-life of 3.0 h. It was rapidly absorbed with a mean peak plasma level occurring at 1.0 h. Plasma levels correlated well with the doses administered. Side-effects included mild nausea, facial flushing and postural symptoms.

    Notes: Summary In a randomised cross-over trial the combination labetalol/hydrochlorothiazide was compared with the combination of propranolol/hydralazine/hydrochlorothiazide in 34 uncomplicated hypertensive patients, who were not satisfactorily controlled with hydrochlorothiazide 50 mg alone. The elevated diastolic pressure (D.P.) in 27 patients responded satisfactorily to the labetalol schedule and in 28 patients to the propranolol/hydralazine schedule. No difference was found in the rate of decrease of D.P., nor in the disappearance of hypertension — related complaints. Although the duration of the washout between treatments was at least one month, treatment was significantly more efficacious during the second period. Labetalol pre-treatment especially seemed to enhance the effect of subsequent propranolol/hydralazine administration. Side effects due to therapy were rare and were not related to any particular treatment. The median daily dose of labetalol in responders was 600 mg and that of propranolol/hydralazine 120/60 mg (in both therapies hydrochlorothiazide 50 mg was given in addition). Patients showed a slight preference for the labetaol medication. It is concluded that labetalol/hydrochlorothiazide and propranolol/hydralazine/hydrochlorothiazide are equally satisfactory in the treatment of uncomplicated hypertension.

    Notes: Summary The efficacy of ticrynafen in the treatment of hypertension in patients with moderate renal impairment was compared with that of hydrochlorothiazide in a randomised, double-blind crossover trial in eleven subjects with renal insufficiency. Significant reductions in blood pressure occurred with both treatments, with the maximum responses occurring at different time intervals and to different degrees in individual patients. Thus, although ticrynafen caused a significant reduction in blood pressure in this group of hypertensive patients with renal insufficiency, it was not consistently different from that which could be achieved with hydrochlorothiazide. Ticrynafen also significantly reduced the serum uric acid concentration, compared with a significant rise with hydrochlorothiazide. No major biochemical abnormalities or side-effects were encountered in any subject. Thus, in these patients with renal insufficiency, ticrynafen still demonstrated a uricosuric effect as well as a useful anti-hypertensive action.

    Notes: Summary In a multicentre, double-blind, crossover, placebo-controlled study, the antihypertensive effect of labetalol 100 mg and chlorthalidone 10 mg, given alone or in combination, has been assessed in 32 hypertensive patients. The combination had a greater effect in reducing blood pressure than did its separate components. This was particularly evident after exercise. Heart rate increased during chlorthalidone therapy, decreased during labetalol therapy, and a summation effect was observed during treatment with the combination. In most cases additivity was observed, as no interaction between the single components was observed, except for heart rate after exercise, and for diastolic blood pressure in the upright position. No interaction was observed either in the biochemical indices or in the clinical side-effects.

    Notes: Summary In a double-blind trial 26 patients with essential hypertension were treated with nifedipine or placebo for 8 weeks, following a 4-week run-in place-bo period in all patients. The daily dosage of nifedipine during this phase was 10mg 3 times daily. Metoprolol was then added to the therapeutic regimen of both groups for a further 12 weeks. Both nifedipine and metoprolol used as mono-therapy caused statistically significant reductions of arterial pressure. The addition of metoprolol to nifedipine tended to reduce blood pressure further, but blood pressures were not significantly lower than during nifedipine mono-therapy. Side-effects were few and only two patients had to be withdrawn during active therapy, one for headaches during nifedipine therapy, and another for asthma during metoprolol treatment. Combined therapy with a beta-adrenoceptor blocking agent, such as metoprolol, and a calcium antagonist with vasodilating properties, such as nifedipine, offers a theoretically interesting approach in the treatment of hypertension, even though the practical outcome in the present study probably suffered from an inadequate dose of nifedipine during the period of combined therapy.

    Notes: Summary Penbutolol (Hoe 893 d), a long-acting non-selective beta-adrenoceptor blocking agent, was given once daily to 23 patients with primary hypertension, WHO Stages I–II. The dose (50–100 mg) needed to achieve the therapeutic goal, i.e. supine diastolic BP〈95 mm Hg, was titrated individually. On a daily dose of penbutolol 83±19 mg (mean±SD) blood pressure (BP, mean±SD) fell from 180±21/112±8 mmHg on placebo to 154±25/94±14 mmHg. 18 patients who reached the therapeutic goal (responders) continued in a double blind, cross-over study versus placebo, during which the supine BP fell on average 20/10 mmHg on the same dose of penbutolol, and 2/1 mmHg on placebo. Plasma concentrations (mean±SD) of free 0.10±0.07 µg/ml) and total (2.02±1.39 µg/ml) penbutolol did not differ between responders and nonresponders, and were not correlated with the fall in BP. Side effects were mild and mostly well tolerated. One patient developed dermatitis and another an elevation of liver enzymes.

    Notes: Summary The effect of clonidine on the number ofα 2-adrenoceptors in human platelet membranes, determined by3H-yohimbine binding, was investigatedin vitro andin vivo. Incubation of platelet membranes with clonidine (1–100 µM) for 16 h at 25 °C led to a concentration-dependent decrease in the number of3H-yohimbine binding sites of 10–25%; the affinity of3H-yohimbine to the sites was not changed (KD approximately 3–4 nM). In such “desensitized” membranes, inhibition of3H-yohimbine binding by clonidine resulted in steep, monophasic displacement curves, which in comparison to the curves from control membranes (IC50 for clonidine 90 nM), were shifted to the right (IC50: 321 nM) and were not affected by 10−4M guanosine-5′-triphosphate (GTP). Treatment of 3 hypertensive patients with clonidine (3×150 µg/d for 7 days) reduced blood pressure and heart rate. Simultaneously, both3H-yohimbine binding sites on platelet membranes and plasma catecholamine levels decreased within three days and remained at a reduced level during treatment. After abrupt cessation of clonidine treatment, blood pressure, heart rate and plasma catecholamines rapidly increased, reaching values after two days similar to or higher than those before treatment.3H-yohimbine binding sites, however, initially decreased further before returning to control values. In platelet membranes derived from hypertensive patients treated with clonidine for at least three weeks, GTP (10−4M) had no influence on inhibition of3H-yohimbine binding by (—)-adrenaline and clonidine. It is concluded that clonidine desensitizesα 2-adrenoceptors in human platelet membranesin vitro andin vivo. An important step in the desensitization process is the uncoupling of receptor occupancy by agonists and adenylate cyclase activity, as indicated by loss of the regulatory activity of GTP on desensitized membranes. The clonidine withdrawal syndrome may be caused by enhanced release of endogenous catecholamines not adequately regulated by presynapticα 2-adrenoceptors, which have become subsensitive after chronic clonidine treatment.

    Notes: Summary Betaxolol is a cardioselective beta-blocker, which has a bioavailability of 90% and a T1/2 of 20 h. A four group, cross-over double-blind trial was conducted to select between betaxolol 20 mg and 40 mg for long term trials. 60 patients were allocated randomly to one of the sequences placebo-20 mg, 20 mg-placebo, placebo-40 mg and 40 mg-placebo, each treatment lasting for 2 weeks. Groups were homogenous for baseline diastolic blood pressure (DBP), age and male/female ratio, and were slightly unbalanced for weight. A two-way ANOVA (3 treatments, 2 sequences) showed no treatment-sequence interaction nor sequence effect. The mean reduction in DBP was 14.2±1.8 mm Hg following 20 mg and 18.0±1.8 following 40 mg betaxolol, and 4.0±1.2 mm Hg during placebo (p〈0.001). Age, weight, baseline DBP and duration of hypertension did not influence the treatment effect. The 95% confidence intervals of the reduction in DBP were 10.4–17.9 for 20 mg and 14.3–21.6 mm Hg for betaxolol 40 mg. Aiming at a mean reduction to 90 mm Hg, betaxolol 20 mg would appear to be adequate in similar patient populations.

    Notes: Summary The antihypertensive effect of a new vasodilator with betablocking properties (SK & F 92657) was investigated in 10 patients with mild to moderate essential hypertension. After a mean treatment period of 26,5 weeks (6,5–49 weeks) blood pressure was significantly reduced, from 168±22/106±6 mmHg to 144±19/94±12 mmHg (p〈0.05 and 0.025). The mean dose was 410 mg (100–700 mg). Heart rate decreased slightly from 77±12 to 70±8 beats/min. Plasma renin activity and plasma aldosterone showed only minor changes. Nausea, heavy dreams, facial and hand flushing and mild depression were reported as side effects. In most patients the symptoms disappeared without reduction in the dose. In one patient anaemia developed after 7 weeks and treatment with prizidilol was stopped. A slight but statistically significant decrease in haemoglobin concentration of 1.1±0.6 g/dl was observed in 5 of the 10 patients (p〈0.02). Thus, a mean dose of prizidilol of 410±242 mg/day had a mean blood pressure lowering effect of 24/12 mmHg. In 7 of the 10 patients (70%) diastolic blood pressure could be reduced to 95 mmHg or less. However, the observed haematological side-effects should be carefully monitored in further studies and may limit the clinical use of prizidilol.

    Notes: Summary Fifteen elderly patients whose hypertension was controlled by conventional propranolol 80 mg twice a day had their medication changed to one capsule of ‘Inderal’ LA1 (160 mg) daily. The blood pressure, heart rate and propranolol concentrations were measured at various time points when the patients were receiving the conventional preparation and these assessments were repeated when the long-acting preparation was administered. Although the heart rate was lower with conventional propranolol than with ‘Inderal’ LA there was no significant difference in the blood pressure levels. The mean peak blood level of propranolol was, however, significantly lower with ‘Inderal’ LA compared with conventional propranolol and occurred later. At 12 h the plasma propranolol levels were higher after ‘Inderal’ LA than following the intake of conventional propranolol (p〈0.01); there was no difference in the plasma levels at 24 h. The area under the concentration time curve was significantly higher on conventional propranolol. Compared with published data, the plasma levels were higher than those in younger patients. ‘Inderal’ LA was well tolerated and side effects were minimal.

    Notes: Summary Eleven patients with uncomplicated essential hypertension received increasing single daily doses of UK-33,274, a new alpha-1 adrenoceptor antagonist, and prazosin for 4 days, in a open cross-over study. Doses were increased until a satifactory blood pressure response was obtained. Average doses reached were 4.5 mg for UK-33,274 and 2.4 mg for prazosin. The maximum effect of the two drugs on standing blood pressure was similar, but prazosin was more effective in the supine position. Both drugs had a greater effect on standing than on supine blood pressure. UK-33,274 caused a consistent increase in heart rate while prazosin did not. Whereas there was no clear difference between the two compounds in the duration of the reduction in blood pressure the onset of action was more gradual for UK-33,274. The incidence of side-effects was similar for both drugs. The data suggest that UK-33,274 is less effective than prazosin in reducing blood pressure.

    Notes: Summary The efficacy and side effects of the new vasodilator carprazidil and the established vasodilator minoxidil were compared in 18 hypertensive patients inadequately controlled by 2 to 4 conventional drugs; the latter included diuretics, beta-blockers and/or sympatholytics and, in half the cases, vasodilators, such as hydralazine, diazoxide or the postsynaptic alpha-blocker prazosin. The vasodilators were withdrawn and, using a crossover design all patients received carprazidil (mean final dose 88 mg) and minoxidil (20 mg) for an average period of 5 to 6 months. The effects of the 2 agents appeared to be qualitatively and quantitatively similar. Both tended to cause sodium retention and an increase in heart rate, which required an increased dose of diuretic in one third of the cases or of a beta-blocker in a quarter. With this approach mean body weight and blood volume were not altered in the established phase of carprazidil or minoxidil treatment; heart rate and plasma norepinephrine tended to be only minimally increased, plasma renin was slightly increased, and plasma aldosterone and epinephrine were largely unchanged. Supine and upright blood pressure were reduced from initial values of 189/113 and 167/113 mm Hg, to 149/95 and 138/95 mm Hg (−18 and −17%), respectively, during carprazidil, and to 154/95 and 141/96 mm Hg (−17 and −15%) during minoxidil therapy. Hypertrichosis occurred with both agents in almost all patients, and limits their more prolonged use in females. No adverse side effects on haematological parameters, liver or renal function were observed, nor was antinuclear antibody detected. It is concluded that carprazidil and minoxidil are equivalent vasodilator agents in the treatment of severe hypertension, particularly in males.

    Reexamination of acoustic evidence in the Kennedy assassination. Committee on Ballistic Acoustics, National Research Council (1982)

    Details
    Publication Date: 1982-10-08
    Description: Sounds recorded in Dallas at the time of the assassination of John F. Kennedy were analyzed by two research groups, whose reports formed the basis for the opinion that two gunmen fired at President Kennedy. These reports and the acoustic evidence have been studied by the Committee on Ballistic Acoustics, and further acoustic analyses, including sound spectrograms, have been performed. The committee finds that the acoustic data do not support a conclusion that a second gunman was involved in the assassination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉New York, N.Y. -- Science. 1982 Oct 8;218(4568):127-33.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6750789" target="_blank"〉PubMed〈/a〉

    Chromatic valence curves: alternative interpretation derived by the direct matching method (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-03-19
    Description: The amount of red chromatic valence of the red-green opponent colors channel of the human visual system has been reported to be greatly reduced in short wavelengths when the hue-matching method is used to measure red valence instead of the more typical cancellation method. Receptive fields with a silent surround were postulated to explain the reduction, and it was emphasized that the reduced valence curve represented the true chromatic valence curve of the visual system. In the present studies the previous results are interpreted to be a direct consequence of the method and the particular matching stimuli used. It is shown that the reduction can be explained by the existing color-matching data without appealing to the silent surround hypothesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ayama, M -- Ikeda, M -- New York, N.Y. -- Science. 1982 Mar 19;215(4539):1538-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063866" target="_blank"〉PubMed〈/a〉

    Mice regrow the tips of their foretoes (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-20
    Description: Mice will replace the tip of a foretoe when it is amputated distal to the last interphalangeal joint. Amputation of the digit more proximal to the joint does not result in regrowth of the foretoe. Though this growth shares certain similarities with the epimorphic regeneration of amphibian limbs, the two processes are not the same. The regrowth reported here in mice is probably similar to the scattered clinical reports of fingertips regeneration in children, and presents a model system with which to explore the controls of wound healing and tissue reconstruction in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Borgens, R B -- CA 20920/CA/NCI NIH HHS/ -- NS 18456/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1982 Aug 20;217(4561):747-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7100922" target="_blank"〉PubMed〈/a〉

    Description: Cultural phenomena may show considerable stability over time and space. Transmission mechanisms responsible for their maintenance are worthy of theoretical and empirical inquiry; they are complex and each possible pathway has different effects on evolutionary stability of traits, as can be shown theoretically. A survey designed to evaluate the importance of some components of cultural transmission on a variety of traits showed that religion and politics are mostly determined in the family, a mode of transmission which guarantees high evolutionary stability and maintenance of high variation between and within groups.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cavalli-Sforza, L L -- Feldman, M W -- Chen, K H -- Dornbusch, S M -- 10452/PHS HHS/ -- 20467/PHS HHS/ -- 20816/PHS HHS/ -- New York, N.Y. -- Science. 1982 Oct 1;218(4567):19-27.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123211" target="_blank"〉PubMed〈/a〉

    A new subtype of human T-cell leukemia virus (HTLV-II) associated with a T-cell variant of hairy cell leukemia (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-05
    Description: Human T-cell leukemia virus (HTLV) is a human type-C RNA tumor virus (retrovirus) previously identified in and isolated from several patients with T-cell leukemias or lymphomas. The known virus isolates from the United States and Japan are closely related and are found in adults with an acute malignancy of mature T cells. A related retrovirus has been found in a patient (Mo) with a somewhat different disease (a T-cell variant of relatively benign hairy cell leukemia). Serum from Mo contains antibodies to the major internal core protein (p24) of HTLV. A T-cell line established from the spleen of Mo expresses HTLV antigens. However, HTLV from Mo is significantly different from all previous HTLV isolates in immunological cross-reactivity tests of p24. The usual prototype HTLV isolate is represented as HTLV-I, and the HTLV from Mo is represented as HTLV-II. Individual members of each subgroup may then be identified by subscript initials of the patient [for example, HTLV-I(CR), HTLV-I(MB), and HTLV-II(Mo)].〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kalyanaraman, V S -- Sarngadharan, M G -- Robert-Guroff, M -- Miyoshi, I -- Golde, D -- Gallo, R C -- New York, N.Y. -- Science. 1982 Nov 5;218(4572):571-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6981847" target="_blank"〉PubMed〈/a〉

    Description: A human B cell line producing a monoclonal antibody to an antigenic determinant of acetylcholine receptors was established by cloning B cells that had been transformed in vitro by Epstein-Barr virus. The B cells were obtained from the thymus of a patient with myasthenia gravis. The antibody produced by the cell line precipitated acetylcholine receptors from denervated and innervated rat muscle and from human muscle, but did not show detectable response to the acetylcholine receptors from the electric organs of Narke japonica. The monoclonal antibody showed identical binding patterns in innervated and denervated rat muscles. Passive transfer of the monoclonal antibody into rats induced moderate muscle weakness and electromyographic changes characteristic of myasthenia gravis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kamo, I -- Furukawa, S -- Tada, A -- Mano, Y -- Iwasaki, Y -- Furuse, T -- Ito, N -- Hayashi, K -- Satoyoshi, E -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):995-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6297000" target="_blank"〉PubMed〈/a〉

    Spectral character of sunlight modulates photosynthesis of previtamin D3 and its photoisomers in human skin (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-28
    Description: The photosynthesis of previtamin D3 from 7-dehydrocholesterol in human skin was determined after exposure to narrow-band radiation or simulated solar radiation. The optimum wavelengths for the production of previtamin D3 were determined to be between 295 and 300 nanometers. When human skin was exposed to 295-nanometer radiation, up to 65 percent of the original 7-dehydrocholesterol content was converted to previtamin D3. In comparison, when adjacent skin was exposed to simulated solar radiation, the maximum formation of previtamin D3 was about 20 percent. Major differences in the formation of lumisterol3, and tachysterol3 from previtamin D3 were also observed. It is concluded that the spectral character of natural sunlight has a profound effect on the photochemistry of 7-dehydrocholesterol in human skin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacLaughlin, J A -- Anderson, R R -- Holick, M F -- AM 27334/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 May 28;216(4549):1001-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6281884" target="_blank"〉PubMed〈/a〉

    Description: Human T cell lymphoma leukemia virus (HTLV) is a human retrovirus (RNA tumor virus) that was originally isolated from a few patients with leukemias or lymphomas involving mature T lymphocytes. Here we report that the serum of Japanese patients with adult T cell leukemia, but not the serum of tested normal donors, contains high titers of antibodies to HTLV. These observations, together with data from Japan showing that adult T cell leukemia is endemic in southwest Japan, suggest that HTLV is involved in a subtype of human T cell malignancy, including Japanese adult T cell leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robert-Guroff, M -- Nakao, Y -- Notake, K -- Ito, Y -- Sliski, A -- Gallo, R C -- New York, N.Y. -- Science. 1982 Feb 19;215(4535):975-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6760397" target="_blank"〉PubMed〈/a〉

    Identification of the constant chromosome regions involved in human hematologic malignant disease (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-05-14
    Description: Specific consistent chromosome translocations are regularly observed in certain human leukemias and lymphomas. For the myeloid leukemias, the constant recombinants are: the long arm of 9 to chromosome 22 in chronic myeloid leukemia, the long arm of 21 to chromosome 8 in acute myeloblastic leukemia, and the long arm of 17 to chromosome 15 in acute promyelocytic leukemia. Three related translocations are seen in Burkitt lymphoma and B cell acute lymphocytic leukemia; in each one, chromosome 8 is involved with chromosome 2, 14, or 22. Analysis of a complex translocation affecting chromosomes 8 and 14 indicates that the translocation of chromosome 8 to chromosome 14 is the critical constant rearrangement. The analysis of the DNA at the translocation sites of these chromosomes, rather than the reciprocal of each translocation, appears to be the most productive focus for initial study. The various immunoglobulin loci are located in chromosomes 2, 14, and 22, the chromosomes regularly involved in translocations in Burkitt lymphoma and B cell acute lymphocytic leukemia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowley, J D -- CA 16910/CA/NCI NIH HHS/ -- CA 19266/CA/NCI NIH HHS/ -- CA 25568/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1982 May 14;216(4547):749-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7079737" target="_blank"〉PubMed〈/a〉

    Sugar and dental caries: a review of human studies (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-30
    Description: Studies of special population groups, epidemiological surveys, controlled longitudinal studies of humans, and longitudinal studies on the effect of sugar substitutes indicate that frequent or high intake of sugary foods predisposes to dental decay. The relation is not always clear-cut, and most studies have important methodological problems and limitations. Longitudinal measurements of caries increments combined with multiple dietary histories are needed to clarity the association between caries and eating habits. The relative cariogenicity of specific foods can be assessed by a combination of in vitro tests, human in vivo tests, and experimental caries in animals. Human diets, however, vary in food items eaten and the frequency and sequence of eating, and these factors can affect the cariogenicity of a food. Therefore, reported correlations must be interpreted with caution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Newbrun, E -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):418-23.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7046052" target="_blank"〉PubMed〈/a〉

    Benzodiazepine receptor-mediated experimental "anxiety" in primates (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: The ethyl ester of beta-carboline-3-carboxylic acid has a high affinity for benzodiazepine receptors in the brain. In the rhesus monkey this substance produces an acute behavioral syndrome characterized by dramatic elevations in heart rate, blood pressure, plasma cortisol, and catecholamines. The effects are blocked by benzodiazepines and the specific benzodiazepine receptor antagonist Ro 15-1788. The benzodiazepine receptor may consist of several subsites or functional domains that independently recognize agonist, antagonists, or "active" antagonists such as beta-carboline-3-carboxylic acid ethyl ester. These results suggest that the benzodiazepine receptor is involved in both the affective and physiological manifestations of anxiety, and that the administration of beta-carboxylic acid ethyl ester to monkeys may provide a reliable and reproducible animal model of human anxiety.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ninan, P T -- Insel, T M -- Cohen, R M -- Cook, J M -- Skolnick, P -- Paul, S M -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1332-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6293059" target="_blank"〉PubMed〈/a〉

    Color vision is altered during the suppression phase of binocular rivalry (1982)

    Publication Date: 1982-11-19
    Description: Increment-threshold spectral sensitivity functions were determined during the dominance and suppression phases of binocular rivalry. The shapes of the functions obtained during the dominance phase exhibited three maxima at approximately 440, 530, and 610 nanometers and resembled functions obtained for nonrivalrous control conditions. However, the functions measured during suppression had a single broad peak near 555 nanometers and were adequately described by functions measured with flicker methods during nonrivalrous conditions. The results indicate that binocular rivalry differentially attenuates opponent-color information relative to achromatic information.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, E L -- Levi, D M -- Harwerth, R S -- White, J M -- EY01139/EY/NEI NIH HHS/ -- EY01728/EY/NEI NIH HHS/ -- EY03611/EY/NEI NIH HHS/ -- R01 EY001139/EY/NEI NIH HHS/ -- R01 EY003611/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 19;218(4574):802-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7134975" target="_blank"〉PubMed〈/a〉

    Norethisterone, a major ingredient of contraceptive pills, is a suicide inhibitor of estrogen biosynthesis (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-03-05
    Description: Norethisterone (17 alpha-ethynyl-19-nortestosterone) is an effective irreversible inhibitor of estrogen synthetase (aromatase), the enzyme responsible for the conversion of androgens to estrogens, even at a 2 X 10(-6) molar concentration. This irreversible inactivation, which is directed toward the active site of aromatase and requires the cofactor-reduced nicotinamide adenine dinucleotide phosphate, is both time- and concentration-dependent. Ethisterone (17 alpha-ethynyltestosterone), in contrast, is not a suicide inhibitor of aromatase even at concentrations of 10(-4) molar.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Osawa, Y -- Yarborough, C -- HDO4945/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Mar 5;215(4537):1249-51.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058343" target="_blank"〉PubMed〈/a〉

    Cholinergic innervation in neuritic plaques (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-04-23
    Description: Although several studies of Alzheimer's disease suggest that the frequency of neuritic plaques in the cerebral cortex is correlated with the severity of dementia and with reduction in presynaptic cholinergic markers in the cortex, the relationship between cholinergic cortical innervation and the pathogenesis of plaques is unknown. The hypothesis was tested that the neurites in the plaque consist, in part, of presynaptic cholinergic axons, many of which arise from neurons in the basal forebrain. This hypothesis was tested by analyzing the character and distribution of plaques in monkeys, aged 4 to 31 years, with staining for acetylcholin-esterase and also with Congo red and silver stains. Immature and mature plaques were rich in acetylcholinesterase. As the plaques matured, the amount of amyloid increased, and the number of neurites and the activity of acetylcholinesterase decreased. End-stage amyloid-rich plaques lacked acetylcholinesterase. These observations indicate that changes in cortical cholinergic innervation are an important feature in the pathogenesis and evolution of the neuritic plaque.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Struble, R G -- Cork, L C -- Whitehouse, P J -- Price, D L -- NS 07179/NS/NINDS NIH HHS/ -- NS 10580/NS/NINDS NIH HHS/ -- NS 15721/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Apr 23;216(4544):413-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6803359" target="_blank"〉PubMed〈/a〉

    Description: Breast-feeding is important to infant nutrition, morbidity, and mortality, and to postpartum amenorrhea (hence to birth intervals). Evidence on breast-feeding patterns in low-income countries from nationally representative World Fertility Surveys and secondary sources shows that in all but a few such countries most children are breast-fed for at least a few months. The limited evidence available on trends seems to indicate a decline in the duration of breast-feeding, but in most of Asia and Africa breast-feeding is almost universal during at least the first 6 months. Earlier weaning is common in Latin America.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popkin, B M -- Bilsborrow, R E -- Akin, J S -- New York, N.Y. -- Science. 1982 Dec 10;218(4577):1088-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146896" target="_blank"〉PubMed〈/a〉

    Description: A previously undescribed species of human leukocyte, or alpha, interferon is present in the serum of many patients with systemic lupus erythematosus. It was shown to be alpha-interferon by neutralization with specific antiserums, affinity column chromatography, and antiviral activity on bovine cells. However, 23 of 30 interferon samples tested were inactivated by incubation at pH 2, a characteristic of human "immune," or gamma, interferon. Multiple samples of interferon from the same patient had similar biological properties, but samples from different patients were not all identical, suggesting that several variants of this species of human alpha-interferon may exist.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Preble, O T -- Black, R J -- Friedman, R M -- Klippel, J H -- Vilcek, J -- R01-AI-07057/AI/NIAID NIH HHS/ -- R01-AI-12948/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1982 Apr 23;216(4544):429-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6176024" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 1982-04-09
    Description: Electrical subcutaneous nerve stimulation of radial, median, and saphenous nerves has been shown to produce prolonged analgesia. In a double blind study, such stimulation also suppressed clonus for 3 hours after stimulation ceased in subjects with spasticity. Since the effect is contralateral, each subject was his own control. Because stimulation of the nerve in the wrist suppressed ankle clonus, the mechanism mediating the effect must be centrifugal inhibition. These results suggest that subcutaneous nerve stimulation may also be a tool in the management of spasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walker, J B -- New York, N.Y. -- Science. 1982 Apr 9;216(4542):203-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063882" target="_blank"〉PubMed〈/a〉

    Description: Contrary to a previous assumption, the center of the expanding pattern of visual flow is not generally useful as an aid in judging the direction of self motion since its direction depends on the direction of gaze. For some visual environments, however, the point of maximum rate of change of magnification in the retinal image coincides with the direction of self motion, independently of the direction of gaze. This visual indicator could be used to judge the direction of self motion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Regan, D -- Beverley, K I -- New York, N.Y. -- Science. 1982 Jan 8;215(4529):194-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7053572" target="_blank"〉PubMed〈/a〉

    Human fetal movement: spontaneous oscillations near one cycle per minute (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-12-24
    Description: Spectral analysis of spontaneous fluctuations in human fetal movement revealed strong oscillations at frequencies between 0.24 and 0.90 cycle per minute, which are much higher than those of the cyclic alternation of quiet and active states in the fetus and neonate. Oscillations at frequencies up to 2.88 cycles per minute were also detected, but they were usually much weaker. The prominent peaks in the fetal movement spectra are in the frequency range of recently reported neonatal motor rhythms, and indicate the existence of a cyclic process controlling spontaneous motor output that oscillates near one cycle per minute and begins to function in utero.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robertson, S S -- Dierker, L J -- Sorokin, Y -- Rosen, M G -- M01RR00210/RR/NCRR NIH HHS/ -- P50HD11089/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1327-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7146916" target="_blank"〉PubMed〈/a〉

    Endemic pleural disease associated with exposure to mixed fibrous dust in Turkey (1982)

    Details
    Publication Date: 1982-04-30
    Description: Pleural mesothelioma, lung cancer, pleural calcification and fibrosis, and interstitial parenchymal fibrosis have been observed among inhabitants of several villages in south-central Turkey. Earlier reports have stated that environmental and lung tissue samples from this area contained the fibrous zeolite mineral erionite, and this mineral has generally been assumed to be the agent responsible for these endemic pathological conditions in the absence of asbestos outcroppings and usage. Several different kinds of asbestos minerals in addition to erionite have now been found in environmental samples taken from the villages where these diseases occur. The lung tissues of mesothelioma patients from these villages contain both fibrous zeolites and asbestos minerals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rohl, A N -- Langer, A M -- Moncure, G -- Selikoff, I J -- Fischbein, A -- New York, N.Y. -- Science. 1982 Apr 30;216(4545):518-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7071597" target="_blank"〉PubMed〈/a〉

    Description: Increases with aging in subperiosteal dimensions and second moments of area (measures of bending and torsional rigidity) in femoral and tibial cross sections are documented in an archeological sample from the American Southwest. Significant differences between cross-sectional sites and between sexes in the pattern of cortical remodeling with age are also present. These differences appear to be related to variations in the stress or strain levels in different regions of the femur and tibia which result from in vivo mechanical loadings of the lower limb.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruff, C B -- Hayes, W C -- AM00749/AM/NIADDK NIH HHS/ -- AM26740/AM/NIADDK NIH HHS/ -- New York, N.Y. -- Science. 1982 Sep 3;217(4563):945-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7112107" target="_blank"〉PubMed〈/a〉

    Alzheimer's disease and senile dementia: loss of neurons in the basal forebrain (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-03-05
    Description: Recent evidence indicates that the nucleus basalis of Meynert, a distinct population of basal forebrain neurons, is a major source of cholinergic innervation of the cerebral cortex. Postmortem studies have previously demonstrated profound reduction in the presynaptic markers for cholinergic neurons in the cortex of patients with Alzheimer's disease and senile dementia of the Alzheimer's type. The results of this study show that neurons of the nucleus basalis of Meynert undergo a profound (greater than 75 percent) and selective degeneration in these patients and provide a pathological substrate of the cholinergic deficiency in their brains. Demonstration of selective degeneration of such neurons represents the first documentation of a loss of a transmitter-specific neuronal population in a major disorder of higher cortical function and, as such, points to a critical subcortical lesion in Alzheimer's patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitehouse, P J -- Price, D L -- Struble, R G -- Clark, A W -- Coyle, J T -- Delon, M R -- MH 00125/MH/NIMH NIH HHS/ -- MH 26654/MH/NIMH NIH HHS/ -- NS 10580/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1982 Mar 5;215(4537):1237-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7058341" target="_blank"〉PubMed〈/a〉

    Type A behavior and elevated physiological and neuroendocrine responses to cognitive tasks (1982)

    Details
    Publication Date: 1982-10-29
    Description: Qualitatively distinct patterns of cardiovascular and neuroendocrine responses were observed in male college students during mental work and during sensory intake task performance. During mental work, Type A (coronary-prone) subjects showed greater muscle vasodilatation and more enhanced secretion of norepinephrine, epinephrine, and cortisol than Type B subjects. During sensory intake, Type A hyperresponsivity was found for testosterone and, among those subjects with a positive family history of hypertension, for cortisol. As a demonstration of combined cardiovascular, sympathetic nervous system, and neuroendocrine hyperresponsivity to specific cognitive tasks in Type A subjects, this study breaks ground in the search for mechanisms mediating the increased coronary disease risk among Type A persons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, R B Jr -- Lane, J D -- Kuhn, C M -- Melosh, W -- White, A D -- Schanberg, S M -- HL-22740/HL/NHLBI NIH HHS/ -- MH-6489/MH/NIMH NIH HHS/ -- MH-70482/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 Oct 29;218(4571):483-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7123248" target="_blank"〉PubMed〈/a〉

    Description: Man, gorilla, and chimpanzee likely shared an ancestor in whom the fine genetic organization of chromosomes was similar to that of present man. A comparative analysis of high-resolution chromosomes from orangutan, gorilla, chimpanzee, and man suggests that 18 or 23 pairs of chromosomes of modern man are virtually identical to those of our "common hominoid ancestor", with the remaining pairs slightly different. From this lineage, gorilla separated fist, and three major chromosomal rearrangements presumably occurred in a progenitor of chimpanzee and man before the final divergence of these tow species. A precursor of the hominoid ancestor and orangutan is also assumed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yunis, J J -- Prakash, O -- New York, N.Y. -- Science. 1982 Mar 19;215(4539):1525-30.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7063861" target="_blank"〉PubMed〈/a〉

    Description: Using a task known to be sensitive to human amnesia, we have evaluated two current hypotheses about which brain regions must be damaged to produce the disorder. Monkeys with bilateral transections of the white matter of the temporal stem were unimpaired, but monkeys with conjoint amygdala-hippocampal lesions exhibited a severe memory deficit. The results indicate that the hippocampus, amygdala, or both, but not the temporal stem, are involved in memory in the monkey and suggest that a rapprochement between the findings for the human and the nonhuman primate may be close at hand.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zola-Morgan, S -- Squire, L R -- Mishkin, M -- MH24600/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1982 Dec 24;218(4579):1337-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6890713" target="_blank"〉PubMed〈/a〉

These fields were assessed by means of recently developed neuromagnetometric techniques. Surface measurements of magnetic spike field strength in the region of the focus appear sufficient to establish the location, depth, orientation, and polarity of currents underlying the paroxysmal discharge.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barth, D S -- Sutherling, W -- Engel, J Jr -- Beatty, J -- 78040-29867-5/PHS HHS/ -- RR07009/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1982 Nov 26;218(4575):891-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6813968" target="_blank"〉PubMed〈/a〉

    Description: The epidermis of live human skin has a permanent electric dipole moment perpendicular to its surface. Voltage responses to a rapid change of temperature are pyroeletric, while voltage responses to pressure pulses are piezoelectric in nature. The time course of the responses depends on dX/dt (X, temperature or pressure). The epidermal surface can react to all physical environmental influences to which nonbiological pyroelectric materials are known to respond. Epidermal voltage signals can be perceived through the intraepidermal and the superficial dermal nervous network. The pyroelectric and piezoelectric properties are also measurable on dead, dry skin samples.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Athenstaedt, H -- Claussen, H -- Schaper, D -- New York, N.Y. -- Science. 1982 May 28;216(4549):1018-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6177041" target="_blank"〉PubMed〈/a〉
