Abstract

Thyrotropin-releasing hormone (TRH) immunoreactivity has been shown previously to be distributed throughout the gastrointestinal tract and the pancreas. This study demonstrated that TRH given intravenously suppresses, in a dose-related manner, sham-feeding induced food intake and inhibits gastric secretion provoked by infusion of pentagastrin or instillation of 10% liver extract into the stomach. TRH also reduces pancreatic response to secretin, caerulein, feeding a meat meal or duodenal acidification. The findings that TRH inhibits gastric and pancreatic secretions induced by exogenous and endogenous stimulants, and that the inhibition by TRH of post-prandial secretion is not accompanied by any change in serum gastrin, indicate that TRH probably acts directly on the exocrine stomach and pancreas.
