The choleretic action of cholecystokinin and cholecystokinin octapeptide in dogs.
Mongrel dogs were prepared by cholecystectomy, ligation of the lesser pancreatic duct, and insertion of gastric and duodenal cannulas. The common bile duct was cannulated through the duodenal fistula for bile collection while the enterohepatic circulation of bile salts was maintained by intravenous infusion of sodium taurocholate. Cholecystokinin (CCK) and cholecystokinin octapeptide (CCK-OP) caused increased bile flow and had no influence on the biliary clearance of erythritol. The results indicate that the predominant mechanism of CCK and CCK-OP choleresis is due to ductular stimulation.
