Stimulated pancreatic and biliary outputs were studied in seven healthy subjects during intravenous infusion of bovine pancreatic polypeptide (P.P.) (mean dose 65 pmol/kg/h). P.P. significantly inhibited outputs of trypsin and bilirubin at plasma concentrations similar to those observed after meals. In four cholecystectomised subjects, P.P. inhibited only trypsin output.
