In order to evaluate the enteropancreatic hormone axis in dogs with pancreatic acinar atrophy, we measured the release of gastric inhibitory polypeptide and pancreatic polypeptide in response to a standard meal and a meal containing pancreatic enzymes in affected dogs and controls. Postprandial release of pancreatic polypeptide was normal in dogs with pancreatic atrophy and was not affected by addition of pancreatic enzymes to the food. Gastric inhibitory polypeptide was not released after a standard meal in affected dogs, but this blunted response was corrected by the addition of pancreatic enzymes to the food. Feeding the enzyme alone did not stimulate a gastric inhibitory polypeptide response. These results, in part, support similar observations previously reported in children with exocrine pancreatic insufficiency associated with cystic fibrosis. We conclude that dogs with idiopathic pancreatic acinar atrophy can be used as an animal model for future study of enteropancreatic hormonal abnormalities that occur in human beings with exocrine pancreatic insufficiency.

UI MeSH Term Description Entries
D008297 Male Males
D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D010188 Exocrine Pancreatic Insufficiency A malabsorption condition resulting from greater than 10% reduction in the secretion of pancreatic digestive enzymes (LIPASE; PROTEASES; and AMYLASE) by the EXOCRINE PANCREAS into the DUODENUM. This condition is often associated with CYSTIC FIBROSIS and with chronic PANCREATITIS.

D010191 Pancreatic Polypeptide A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice. Pancreatic Polypeptide (PP),Pancreatic Polypeptide Hormone,Pancreatic Prohormone
