We have investigated a negative feedback mechanism in the intestinal phase of pancreatic exocrine secretion in dogs with gastric cannulas and Thomas duodenal cannulas in whom pancreatic juice was collected by cannulation of the main pancreatic duct. Intraduodenal infusion of oleic acid emulsion in a dose of 18 mmol/h resulted in a significant increase in pancreatic secretion of water, bicarbonate, and protein, which was accompanied by increased plasma concentrations of both secretin and cholecystokinin. Infusion of pancreatic juice or bovine trypsin into the duodenum significantly inhibited the oleic acid-stimulated pancreatic secretion. This inhibition coincided with a significant decrease in plasma secretin level, whereas plasma cholecystokinin concentration was not affected by either pancreatic juice or trypsin. Neither pancreatic secretion nor plasma secretin concentration was affected by intraduodenal administration of NaHCO3 solution. The trypsin-induced suppression of pancreatic secretion was prevented by intravenous administration of secretin in a dose that achieved a plasma secretin level comparable to that during the oleic acid administration. This study indicates that a negative feedback mechanism is operative in the intestinal phase of pancreatic exocrine secretion in dogs, and endogenous secretin plays a significant role in the mechanism.
