1. Gastric inhibitory polypeptide (GIP) is not the primary mediator of the enterogastrone action of fat in the dog
T Yamagishi, H T Debas Gastroenterology. 1980 May;78(5 Pt 1):931-6.
We compared the inhibition of food-stimulated gastric acid secretion and changes in serum concentrations of immunoreactive gastric inhibitory polypeptide and gastrin caused by: (a) duodenal perfusion of oleic acid, and (b) intravenous infusion of pure, natural, porcine gastric inhibitory, polypeptide in dogs with gastric fistula and pancreatic fistula. A rate of duodenal perfusion of oleic acid (12 ml/hr) which gave near maximal pancreatic protein response was chosen. This dose of oleic acid caused complete suppression of acid response to a meal of liver extract (300 ml of a 15% solution) while elevating serum immunoreactive gastric inhibitory polypeptide modestly. By contrast, intravenous administration of gastric inhibitory polypeptide that raised serum immunoreactive gastric inhibitory polypeptide several fold caused only 40% inhibition of acid response to the same meal. Other effects of duodenal perfusion of oleic acid were exaggeration of pancreatic protein secretion and significant inhibition of gastrin release in response to the meal. Exogenous administration of gastric inhibitory polypeptide, on the other hand, was without significant effect on these responses. These results suggest that, in the innervated dog stomach, the enterogastrone action of fat is not primarily mediated by gastric inhibitory polypeptide.
