Abstract

Effects of secretin and somatostatin on acid secretion and its relation to prostaglandin E, I2 release in the totally isolated vascularly perfused rat stomach were studied. The results showed: (1) Secretin and somatostatin both markedly inhibited acid secretion stimulated by pentagastrin. Indomethacin could reverse the inhibitory effects of acid secretion by secretin and somatostatin. (2) Secretin increased PGE and PGI2 metabolite 6-Keto-PGF1 alpha release significantly. Somatostatin only increased PGE release. Indomethacin could block stimulatory affects of secretin on PGE, 6-Keto-PGF1 alpha release and somatostatin on PGE release. These results indicated that: (1) inhibition of acid secretion by secretin was mediated by PGI2 and PGE release; (2) inhibition of acid secretion by somatostatin was mediated only by PGE release.
