Acidification of the Gastric Antruin and Inhibition of Gastric Secretion

Abstract
Acidification of the vagally-denervated antrum in our experiments failed to inhibit: histamine-induced fundic secretion, exogenous gastrin-induced fundic secretion, but inhibited: acetylcholine-induced fundic secretion at a rate of 83.5%. These findings suggest that antral acidification acts as a local mechanism to suppress formation or release of gastrin, and not via an inhibitory hormone.
