Abstract: We investigated the role of endogenous prostaglandins in the inhibitory effect of exogenous secretin and the antiulcer agent plaunotol on gastric acid secretion in the rat. Intravenous infusion of secretin (0.05 CU/ kg/h) and intraduodenal administration of the secretin-releasing agent, plaunotol (320 mg/h ), resulted.
