Abstract/OtherAbstract:
We have examined the effect of synthetic human cholecystokinin (CCK-33 and CCK-8) on pancreatic blood flow and protein output in anesthetized dogs. Human CCK-33 and CCK-8 increased pancreatic blood flow and protein output in a dose-related manner. There were no significant differences in increasing pancreatic blood flow between human CCK-33 and CCK-8, and increases in blood flow were closely related to the increase of the pancreatic enzyme secretion. L-364,718 (20 nmol/kg) caused a potent inhibition of CCK-stimulated pancreatic blood flow as well as protein output. The degree of inhibition by L-364,718 was dependent on the amount of CCK infused. This study demonstrates that increasing effect on pancreatic blood flow may be one of the biological actions of CCK mediated via CCK receptor. The CCK-33, one of longer molecular forms of CCK, is an important biological stimulator of pancreatic blood flow as well as of exocrine pancreatic secretion.
