Effects of prostaglandins on renin substrate production by the liver.
1. The effects of prostaglandin (PG) E1, PGE2 and PGF2 alpha on plasma renin substrate concentration in rats and renin substrate production by perfused rat liver were investigated. 2. After bilateral nephrectomy, both plasma renin substrate concentration and renin substrate production were remarkably elevated. 3. The increase in plasma renin substrate level and production of renin substrate by ...
متن کاملPlatelet angiotensin II binding and plasma renin concentration, plasma renin substrate and plasma angiotensin II in human pregnancy.
1. The results are presented of a cross-sectional study of 25 non-pregnant and 125 pregnant/postnatal women in whom platelet angiotensin II binding and plasma angiotensin II, plasma renin concentration and plasma renin substrate were measured. 2. Platelet angiotensin II binding was significantly lower in the first-trimester patients as compared with the non-pregnant women (P less than 0.001). S...
متن کاملPlasma renin activity and renin-substrate concentration in patients with liver disease.
Peripheral venous renin activity was determined by the method of Boucher in 15 patients with cirrhosis of the liver and ascites who were on an unrestricted sodium intake. Positive sodium balance was present in all subjects. Marked elevation of mean plasma renin activity (43 ng angiotensin II/min per liter, SD ± 38) was present. The mean plasma renin activity in 16 normal ambulatory subjects on ...
متن کاملFactors influencing plasma renin and renin substrate in premature infants.
Concentrations of plasma renin (PRC) and plasma renin substrate (PRS) were measured during the first week of life in 52 infants born at less than 37 weeks' gestation (mean (SEM) gestation 30 (0.4) weeks, mean (SEM) birth weight 1.35 (0.08) kg). Both PRC (median 35, interquartiles 16.3, 94.5 ng/ml/hour) and PRS (median 2.3, interquartiles 1.3, 5.0 micrograms/ml) were raised compared with adults....
متن کاملIncrease of plasma renin-substrate concentration after infusion of angiotensin in the rat.
Although a variety of stimuli lead to large changes in the plasma concentration of reninsubstrate, the mechanisms involved are not fully understood (see Helmer & Judson, 1967; Carretero & Gross, 1967a, b; Bing & Poulsen, 1969). Increased plasma renin-substrate concentration (PRSC) is sometimes found in renal hypertension (Helmer & Judson, 1963; Gould, Skeggs & Kahn, 1966), and in a recently rep...
