In adult male rats, fundusectomy decreased acid secretion but significantly increased total antral gastrin and both fasting and food-stimulated serum gastrin levels. The rise in fasting serum gastrin could be inhibited by antral acidification, suggesting that decreased acidity caused postfundusectomy hypergastrinemia. The mechanism for the increase in total gastrin in antral tissue is probably the same. These studies provide a useful experimental model for the increasing of antral gastrin and for the production of hypergastrinemia.
