N2 - BACKGROUND: Glucagon-like peptide (GLP-1) 7-36 amide and peptide YY (PYY) from the L-cell of the ileal mucosa are potent inhibitors of gastric acid secretion in man. It is not clear, however, by which mechanism(s) they inhibit acid secretion. In dogs the inhibitory effect of PYY on acid secretion may be mediated mainly through neural pathways. The mechanism of action of GLP-1 might be similar. The aim of the present study was to examine the effects of GLP-1 might be similar. The aim of the present study was to examine the effects of GLP-1 and PYY on the vagally induced gastric acid secretion in man.METHODS: A modified sham feeding technique, chew and spit, was used. Six healthy volunteers were randomly assigned to receive intravenous infusion of saline, GLP-1 (41 pmol/kg/h), or peptide YY (50 pmol/kg/h).RESULTS: The infusion of GLP-1 and PYY resulted in plasma concentrations of 60 +/- 9 pmol/l and 84 +/- 11 pmol/l, respectively. GLP-1 and PYY both significantly inhibited the intergrated acid output by 67 +/- 6% and 68 +/- 9%, respectively, compared with the integrated outputs in a control experiment with saline infusion. Serum gastrin and plasma somatostatin concentrations remained unchanged during saline, GLP-1, and PYY infusions.CONCLUSIONS: GLP-1 and PYY are both potent inhibitors of the cephalic phase of acid secretion, indicating that at least part of the inhibitory effect of GLP-1 and PYY in man is mediated through neural pathways. Furthermore, the inhibitory effect seems to be independent of circulating concentrations of gastrin and somatostatin.
