Gastric acid secretion, as well as gastrin and pancreatic peptide release into the bloodstream before and after TV or HSV were observed in 28 patients following modified sham feeding (MSF) and pentagastrin tests. Prior to surgery the majority of patients showed stimulation of gastric acid secretion and hormone release into the bloodstream as the result of the employed tests. The MSF-induced acid output (SAO) and pentagastrin-induced acid output (PAOpg) values were mainly observed immediately following the stimulus. In the majority of patients MSF triggered an increase in blood gastrin and PP concentrations. Nevertheless, the peak concentration values for the two hormones occurred at different time intervals following the stimulus. For gastrin the peak values appeared later than SAO, whereas for PP they occurred either in the course of or immediately after MSF. Irrespectively of, the type of surgical procedure used and the completeness of vagotomy, the values of BAO, PAO, SAO and PAOpg were significantly lower following the procedure. Blood hormone concentration, however, showed greater variations. The test stimulated gastrin release showed the peak values were greater after, than prior to, the surgery, whereas PP release was markedly inhibited. No correlation was found between gastric acid secretion, blood serum gastrin and PP levels.

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
