title: Release of cholecystokinin in response to food and intraduodenal fat in pigs, dogs and man.
abstract: The present study was done to compare endogenous cholecystokinin-33 release in response to physiologic stimuli (meal, fat) in pigs, dogs and man. Plasma levels of cholecystokinin-33 were monitored using a radioimmunoassay for cholecystokinin which detects only cholecystokinin-33 and cholecystokinin-39. Ingestion of a meal caused release of cholecystokinin-33 within five, 20 and 120 minutes in man, pigs and dogs, respectively. Intraduodenal administration of corn oil resulted in a significant release of cholecystokinin-33 within 20 minutes in dogs, pigs and man.
