title: [Regulation of the renin-angiotensin-aldosterone system. Role of the prostaglandins].
abstract: PRA (in the supine and erect subject) and urinary sodium before and after acute treatment (100 mg i.m.) and chronic treatment (100 mg per os for 8 days) were examined in two groups of subjects with no signs of cardiovascular or renal disease. It was found that indomethacin, which is a well-known inhibitor of prostaglandin synthesis, reduced PRA levels in basal conditions and as a result of postural stimulation, without causing any appreciable change in urinary sodium. Regulation of the PRA on the part of the renal prostaglandins is postulated and its probable mechanisms discussed.
