    Notizen: Summary Propranolol was given to 30 patients with essential hypertension following randomised, double-blind administration of either placebo or a new cardioselective beta-adrenergic receptor antagonist, atenolol (Tenormin®, ICI 66 082). Both atenolol and propranolol caused statistically significant reduction of recumbent and erect blood pressure and heart rate. There were no important differences between these variables on comparison of atenolol and propranolol.

    Notizen: Summary A study, using non-invasive techniques, was carried out in ten patients with essential hypertension to examine the mechanism of the hypotensive effect of propranolol when used in combination with a potent vasodilator antihypertensive — minoxidil. The hypotensive effect of minoxidil, a mean (± SEM) decrease of 42.4±4.3 mm Hg, was accompanied by a marked increase in heart rate, cardiac index and plasma renin activity and a significant decrease in total peripheral resistance, limb vascular resistance and pre-ejection period. Addition of propranolol further reduced mean arterial pressure by an average of 12.9±2.0 mm Hg. Propranolol returned cardiac index to control values and total peripheral resistance index rose but not to control levels. Plasma renin activity was significantly reduced by propranolol. By multiple regression analysis no correlation was found between propranolol-induced decrease in mean arterial pressure and changes in cardiac index, total peripheral resistance index or plasma renin activity. Quantitatively, the reduction in cardiac index observed probably accounted for the hypotensive effect of propranolol. The role of plasma renin activity reduction in the hypotensive effect of propranolol in this situation remains to be clarified. The findings in the present study were consonant with the known actions of vasodilator antihypertensive agents and propranolol and indicate the applicability of non-invasive methodology to the investigation of cardiovascular drugs in man.

    Notizen: Summary The antihypertensive activity and side effects of three doses of hydrochlorothiazide combined with a potassium supplement (Esidrex®-K novum, Ciba) were determined in 40 hypertensive subjects in a double-blind, cross-over study. The lowest daily dose (12.5 mg) gave almost the same blood pressure reduction as the doses in common use (25 mg and 50 mg) and as the adrenergic beta-blocking agents previously employed. Metabolic side effects in the form of decreased serum potassium and increased fasting blood sugar and serum uric acid were observed in patients on the lower dose and, with the exception of serum uric acid, were only slightly more pronounced with the higher doses. The frequency of subjective side effects, on the other hand, increased with increasing dose. No changes were noted in total body potassium at any dose level. It is suggested that hydrochlorothiazide in low dose, alone or in combination with other antihypertensive agents, is a useful therapeutic regimen in mild hypertension.

    Thema: Biologie , Medizin
    Notizen: Abstract The content of lipid granules in the interstitial cells (IC) of the renal medulla of rats with genetic spontaneous hypertension (rats of the SHR strain) was studied by electron-microscopic morphometry. At the age of 1.5 months no difference was found in the volume of the lipid granules in SHR and Wistar (control) rats. At the age of 1 year the total volume of lipid granules in hypertensive SHR rats exceeded their volume in the control. At the same time, features of hypertrophy and hyperplasia of the rough and smooth endoplasmic reticulum and Golgi complex were found in the SHR rats, especially in the period of formation of hypertension. It is evidently not the degree of reduction in the volume of lipid granules, as was hitherto considered, but the state of the organelles of synthesis and secretion that must be used as the morphological criterion of IC function in arterial hypertension.

    Notizen: Abstract In experiments on freely moving rabbits, exposed to prolonged (for 2 h) interrupted stimulation of negative emotiogenic zones of the hypothalamus through implanted electrodes daily for 4 months, the development of a lasting endogenous hypercholesteremia and of a mild but lasting hypertension was observed. Changes in the cholesterol concentration were greater if stimulation continued in conjunction with daily feeding of the rabbits with small doses of methylthiouracil.
