[Effect of hypophysectomy on gastrin release and antral gastrin concentration].
Hypophysectomy resulted in a lower amount of basal serum gastrin. In hypophysectomized rats, there was a release of serum gastrin after food intake; however, the serum gastrin level was lower 30 min postprandially. The most important effect of hypophysectomy is absence of repletion of antral gastrin after an initial postcibarial depletion. We conclude that the immediate synthesis of antral gastrin after food intake is inhibited by hypophysectomy.
