title: [Interdigestive and postprandial pancreatic exocrine secretion and cholecystokinin release in dogs].
abstract: Interdigestive and postprandial pancreatic exocrine secretion and cholecystokinin (CCK) release were investigated in 5 mongrel dogs with chronic gastric and pancreatic fistulas in this study. The rapidly exaggerated postprandial pancreatic exocrine secretions were shown to be directly correlated to the rapid CCK release after meal. Corresponding to the previous studies, in the interdigestive state, pancreatic exocrine secretion showed cyclic changes which would be abolished by intravenous administration of atropine sulfate. However, we failed to demonstrate any significant correlation between plasma CCK levels and periodic pancreatic exocrine secretions during the interdigestive state through CCK radioimmunoassay. Furthermore, intravenous administration of atropine sulfate did not change the plasma CCK levels significantly in the interdigestive state. Having reviewed the literature, we thought that the periodic pancreatic exocrine secretion during the interdigestive state might be related to motilin release and cholinergic enteropancreatic reflex.
