Abstract
Effects of biogenic monoamines and their precursors on stress ulcers and secretion in stomach were investigated herein. Norepinephrine, 5-HT and their precursors prevented formation of stress ulcer at any level of endogenous monoamines in reserpine or iproniazid-treated rats. These same agents did not affect the stressinduced decrease in the output of PSB but increased the pH value of gastric juice.
