Abstract

1. Stimulation of prostanoid release by angiotensins (AI and AII) in rat isolated mesenteric vasculature and in the circulation of anaesthetized dogs has been investigated by bioassay. 2. AI and AII released a PGI2-like substance into rat mesenteric effluent and arterial blood of dogs; PGE2, PGF2 alpha, or TXA2 were not detected. 3. AI stimulated PGI2 release in both systems largely as a result of its conversion to AII, since PGI2 release was much reduced after treatment with captorpril. 3. AI stimulated PGI2 release in both systems largely as a result of its conversion to AII, since PGI2 release was much reduced after treatment with captopril. 4. Intravenous AII (0.02-1.0 microgram kg-1min-..
