Abstract
The role of prostaglandins as mediators of the inhibitory effect of somatostatin on gastric acid secretion has been evaluated in conscious and anesthetized rats. The effect of somatostatin on bethanechol-stimulated gastric acid secretion was determined with or without indomethacin pretreatment. Prostaglandin synthesis inhibition (less than 90%) by indomethacin was verified with PGE2-generation assay on gastric mucosal tissue. In both conscious and anesthetized rats somatostatin significantly inhibited the stimulated acid output in the control and indomethacin pretreated groups. The present findings do not support a role for prostaglandins in the inhibition of gastric acid secretion by somatostatin in the rat.
