title: Effect of secretin, glucagon and duodenal acidification on bombesin-induced hypergastrinemia in man.
abstract: The action of duodenal acidification, of continuous I.V. infusion of secretin and glucagon and of a one bolus I.V. administration of secretin and glucagon at maximal doses on BBS-induced gastrin secretion has been studied in a group of 18 healthy subjects. Continuous infusion of secretin and glucagon and the acidification of the duodenum did not alter significantly the levels of gastrin stimulated by BBS. Secretin and glucagon administered by a single I.V. bolus paritially inhibit the effect of BBS on gastrin levels. On the basis of these results it is not possible to affirm or to exclude the possibility that BBS is a hormone physiologically present in man.
