Inhibition of pancreatic exocrine secretion and augmentation of the release of gut glucagon-like immunoreactive materials by intraileal administration of bile in the dog.
The effect of intraileal instillation of bile, a stimulant of gut glucagon-like immunoreactive materials (gut GLI), on secretin-stimulated pancreatic secretion was examined in anesthetized dogs. Intraileal bile significantly inhibited the flow rate of secretin-stimulated pancreatic secretion. The inhibition of pancreatic secretion was accompanied by an elevation of plasma concentration of gut GLI. Taking the inhibitory effect of glucagon on pancreatic exocrine secretion into consideration, it could be reasonably postulated that gut GLI may be a mediator of bile-induced ileal inhibition of pancreatic exocrine function.
