Cortisol and pancreatic secretion. Observations on pure pancreatic juice

In view of the conflicting results in the literature, we undertook a study of the effects of intravenous administration of control on the external secretion of the pancreas. The study was carried out in five subjects with external transduodenal drainage of the main pancreatic duct, performed after biliary tract surgery. The intravenous injection of cortisol, 100 mg, during a constant intravenous infusion of secretin and cholecystokinin did not cause any significant change in pancreatic secretion. The results do not confirm previous findings in man indicating an inhibitory effect of glucocorticoids given intravenously on exocrine pancreatic secretion.
