title: Inhibition of acid secretion from vagally innervated and denervated gastric pouches by (Gln4)-neurotensin.
abstract: In dogs with innervated fundic pouches an intravenous infusion of (Gln4)-neurotensin, 60 pmol X kg-1 X min-1, reduced the pentagastrin-stimulated acid secretion to 40% of the control secretory rate. After vagal denervation of the fundic pouches the same dose of (Gln4)-neurotensin did not significantly change the secretion. These findings suggest that (Gln4)-neurotensin does not act directly on parietal cells but inhibits acid secretion at a presynaptic level.
