Protective effect of coptisine free base on indomethacin-induced gastric ulcers in rats: Characterization of potential molecular mechanisms

The aim of this study was to comparatively investigate the potential gastroprotective effect and underlying mechanisms of coptisine free base (CFB, 8-hydroxy-7, 8-dihydrocoptisine), berberine and lansoprazole against indomethacin-induced gastric ulcer in rats. CFB (10, 20 and 40 mg/kg), berberine (20 mg/kg) and lansoprazole (30 mg/kg) were orally administrated to rats prior to indometacin ingestion, and gastric lesions were evaluated...
