Atropine-induced inhibition of the enhanced CCK release observed in alcoholic dogs.
As it has been previously shown, the pancreatic secretory response to an intraduodenal infusion of oleic acid is increased in animals accustomed to daily ethanol consumption compared to matched controls. This action has been verified in dogs provided with a Thomas cannula and consuming 2 g kg-1 ethanol or not, daily since 3 years. An intravenous infusion of 0.75 mg kg-1 h-1 of atropine suppresses the difference between alcoholic and non-alcoholic animals. Therefore, the increased release of CCK-PZ in response to meal, which is characteristic of chronic alcoholic animals, is under cholinergic control.
