[Effects of ranitidine on regenerating parietal cells. A stereologic study].
In this work, we have carried out a stereological and morphological study in order to verify the effects of Ranitidine on regenerating parietal cells. We have used a control group and operated or non-operated groups treated with 2, 10 and 50 mg/kg/day Ranitidine. In operated groups an ulcer was provoked by cauterization with a metallic plate in the gastric fundus. Groups treated with high doses of Ranitidine showed an increase in the connective tissue of the gastric mucosa. The stereological study in treated groups shows a decrease in the parietal volume density, and an increase in the cellular profile. Changes detected in the parietal volume density would originate a decrease in the production of CIH.
