Abstract
The systemic administration of glucocorticoids has not only strong beneficial anti-inflammatory and immunosuppressive effects but also numerous adverse health effects. Therefore, this study aimed to investigate the stereological and ultrastructural characteristics and distribution of gastrin-producing G cells in rat antral mucosa after 12 days of intraperitoneal administration of 2 mg/kg dexamethasone (DEX). In both groups of rats (DEX and control), the G cells were located at the base of the antral mucosal crypts, but in the DEX-treated rats, they were also found near the gastric lumen and showed an altered morphology compared to the basal cells. There were significant differences in the number of G cells per unit area and unit volume of antral mucosa between the groups studied. In the DEX-treated rats, the modified morphology and position of the antral G cells within the gastric units indicate their modified activity and possible impaired regulation of gastric acid production.
