Arterial Gastroduodenal Infusion of Cholecystokinin-33 Stimulates the Exocrine Pancreatic Enzyme Release Via an Enteropancreatic Reflex, Without Affecting the Endocrine Insulin Secretion in Pigs

Cholecystokinin (CCK)-dependent exocrine pancreatic regulation seems to involve different pathways in different species. The aims were to explore the enteropancreatic reflex in the CCK-mediated regulation of the exocrine pancreas and to evaluate a possible involvement of this reflex in the endocrine insulin release.
