title: Effects of cholecystokinin-pancreozymin on bile flow and biliary bile salt secretion in the cholecystectomized animal.
abstract: The effects of an intravenous infusion of cholecystokinin-pancreozymin on bile secretion were studied in 13 unanesthetized and cholecystectomized piglets. The results demonstrate that CCK-PZ induces a significant increase of bile flow and bile salt excretion. The excretion patterns for bilirubin and Ioglycamide, however, showed a slight but not significant decrease. Peripheral hemodynamic parameters remained unchanged. A detailed analysis of these results suggests that CCK-PZ induces an increase of biliary bile salt secretion by stimulation of intestinal motility and enhancement of bile salt circulation within the enterohepatic circulation (EHC). In combination with previous studies on the effects of spasmolytics on biliary bile salt excretion these results therefore emphasize, that the intestinal motility and transit time might play a role in the physiology and pathophysiology of biliary bile salt secretion.
