Abstract

Dystrophic lesions of the gastric mucosa were observed to be formed and the pepsinogen content was reduced by 57% in the gastric mucosa of rats exposed to various experimental stressors (immobilization with electrical stimulation, immobilization at 6°C, trauma to or ligation of the pylorus). and the changes correlated with the degree of injury to the stomach. Pharmacological blockade of H2 receptors by cimetidine (100 μmoles/kg) and methiamide (410 μmoles/kg) largely prevented the formation of experimental ulcers and the decrease in the pepsinogen level. The results indicate that endogenous histamine participates in the mechanism of formation of dystrophic gastric lesions.
