Abstract
Renin release from renal cortical slices of baboon kidneys was measured. It was found that the basal release rate was directly proportional to the renin content. Release was stimulated in a dose-dependent fashion by isoproterenol and was inhibited both by angiotensin II and vasopressin. Maximum inhibition was approximately 30%. Experiments also were done in which angiotensin II and converting enzyme inhibitor were infused into the lateral ventrical of anesthetized baboons. Angiotensin caused a reduction in plasma renin activity (PRA), and converting enzyme inhibitor an increase in PRA, independent of changes in blood pressure.
