Chronic Alcohol Consumption Does Not Modify Cholecystokinin Blood Levels Estimated by Bioassay in the Dog

Abstract
Blood levels of cholecystokinin (CCK) were estimated by a bioassay on in vitro rabbit gallbladder in 2 series of dogs: 5 dogs receiving daily, for 12-18 mo., 2 g kg-1 ethanol through a gastric cannula and 5 control dogs which did not receive ethanol. CCK-like activity was no different in either group, neither in the fasting state nor after intraduodenal injection of oleic acid or intragastric injection of ethanol.
