title: Secretin-pancreozymin test with synthetic secretin and cholecystokinin octapeptide.
abstract: Pancreatic responses to submaximal doses of synthetic secretin (125 ng/kg) and cholecystokinin octapeptide (50 ng/kg) were investigated in controls and patients with pancreatic disease. Doses of stimulants were chosen from dose-response experiments to avoid supramaximal amounts which inhibited the pancreatic response. Injection of secretin resulted in duodenal juice in less trypsin but more lipase activity than that elicited by cholecystokinin octapeptide. The increase of amylase was about the same. Diagnostic efficacy of pancreatic responses to the individual hormones was similar. An overall evaluation of the results seems to be the most reliable method for diagnostic purposes.
