Histopathological evaluation of gastro protective effect of Berberis vulgaris (Zereshk) seeds against aspirin induced ulcer in albino mice

The present study was carried out to investigate the antiulcer activity of berberis vulgaris (zereshk) seeds in albino mice. after acclimatization,animals were divided into six equal groups. aspirin 150mg/kg was used to induce gastric ulcer in all groups except normal control. omeprazole 20mg/kg was used as synthetic anti ulcer drug in study. three dose levels of b. vulgaris seed powder 300mg/kg,600mg/kg and 900 mg/kg were used respectively orally. histopathological analysis was carried out to evaluate the gastroprotective activity of b. vulgaris seed powder. results of the study showed that in case of aspirin treated mice gastric luminal mucosa villi were decreased in height or were absent. in the glandular region there was connective tissue proliferation and also infiltration of cells. similar infiltration of cells was present on muscularis mucosa. in esophageal region tumor cells were present. however three dose levels of b. vulgaris significantly reduced thetissue proliferation,infiltration of cells and sloughing induced by aspirin. highest dose of b. vulgaris (900mg/kg) showed similar results as synthetic antiulcer drug omeprazole.
