Gastrin release by ethanol in man and in dogs

In man, oral or intravenous administration of ethanol caused a small but definite increase in peripheral serum gastrin concentration (measured by radioimmunoassay). In dogs, perfusion of the antrum with 10% ethanol caused an immediate increase in gastrin levels in the antral venous outflow. Acidification of the perfusate did not totally block the gastrin release from the antrum. Intravenous infusion of ethanol in dogs caused release of gastrin from the antrum.
