[Concentration of pancreatic polypeptide, gastrin, and motilin in the plasma of dogs during the digestive process in pancreatic atrophy].

Fasting and postprandial concentrations of pancreatic polypeptide, gastrin and motilin were measured during 2hrs after meat feeding. The byphasic rise of pancreatic polypeptide concentration occurred in 15 and 120 min and increase of gastrin concentration--in 15 min after feeding. Increase of motilin concentration occurred during the second hour. These findings complete our previous data and suggest that hormonal mechanisms involved in postprandial response are maintained even in pancreatic atrophy.
