in dogs with gastric and pancreatic thomas fistulas the effect of different cholecystokinin-like peptides upon pancreatic polypeptide ( pp ) release was studied in three ways : ( a ) plasma pp concentrations were determined by radioimmunoassay in response to 135 pmol/kg/h of the synthetic c-terminal octapeptide of cholecystokinin ( cck-op ) ( a ) , of three of its analogues ( b , c , d ) where methionine has been replaced by methoxinine , and in response to 45 pmol/kg/h of caerulein .
