[Quantitative assessment of gastric mucosal bleeding in the development of acute gastric mucosal lesions in the rat and prophylactic effect of elcatonin].
Intraperitoneal injection of indomethacin (5, 10 and 20 mg/kg) caused acute gastric mucosal lesions in the conscious restrained rat and also hypersecretion of gastric acid. Cimetidine, an H2-receptor antagonist, was found to prevent gastric mucosal bleeding and acid secretion induced by indomethacin. Elcatonin at higher doses than 2.5 U/kg (0.5 microgram/kg) was effective for protecting the gastric mucosa against indomethacin irritation, and it inhibited acid output in response to this ulcerogen. The acid inhibitory effect of elcatonin might be implicated in its cytoprotective action.
