..., low-to-normal renin levels, by immunoreactive active renin and plasma renin concentration measurements, and a blunted response of PRA to captopril, were seen. As compared with HR-RVH, LNR-RVH patients had a longer duration of hypertension ( P < 0.05), higher serum K + ( P = 0.04) and lower...

...). Calculated absolute distal sodium reabsorption [( C Li – C Na ) × P Na , where P Na is plasma sodium concentration] increased by 40% ( P <0.001). Plasma renin concentration did not change significantly. 4. The results suggest that amino acids increase GFR by a primary effect on renal haemodynamics...

...Jitsuo Higaki; Toshio Ogihara; Yuichi Kumahara 1. The plasma renin concentration (PRC) and active renin concentration determined by radioimmunometric assay (ARC) were measured before and after administration of frusemide or captopril to normal volunteers. 2. Injection of 40 mg of frusemide followed...

.... Destruction of at least half of the papilla caused significant hypertension, but plasma renin concentration and plasma creatinine did not change. 3. After graded medullary damage Goldblatt two-kidney, one-clip hypertension was induced. Four weeks later the severity of hypertension was similar in medulla...

... blood pressure, plasma- renin concentration and renal function were measured regularly in recipients of an allogeneic kidney transplant that had previously undergone active immunological enhancement. 3. Transplant recipients on a normal diet showed a rise in systolic blood pressure during the second...

..., the positive feedback of angiotensin II on hepatic renin substrate synthesis may be inhibited. 4. The sequential changes in renin release during captopril treatment should be monitored by measuring plasma renin concentration since plasma renin activity measurements will be profoundly influenced by the marked...

... blood flow were significantly lower in low-renin hypertension. Total peripheral and renal vascular resistance were markedly higher in this group. 3. Plasma renin concentration correlated inversely with both total peripheral and renal vascular resistance as well as with age. Multiple regression analysis...

...R. Fagard; A. Amery; J. F. Deplaen; P. Lijnen; A. Missotten 1. The anti-hypertensive effect of atenolol was greater than that of bendrofluazide. 2. The change in systolic blood pressure caused by bendrofluazide showed a significant inverse correlation with the plasma renin concentration ( r = −0·47...

... filtration rate, and renal vascular resistance showed a significant decrease. Blood volume and plasma renin concentration did not change significantly. An inverse relation between changes in plasma volume and plasma aldosterone concentration was observed. In the face of similar reductions in blood pressure...
