اثر ویتامین E خوراکی بر زخم معده ناشی از آسپرین از راه خوراکی و تزریقی در موش رت

Background &Aims: Gastric ulcers are common worldwide that occur due to different agents such as stress, cigarettes, non-steroid anti inflammatory drugs (NSAIDs) administration, and ethanol. NSAIDs are responsible for 15- 25 % all gastric ulcers. This study was done to evaluate the effects of oral vitamin E on oral and intra peritoneal (I.P) aspirin induced-gastric ulcers in rats. Materials & Methods: This experimental (interventional) study was done on 30 rats weighing 200±20 gr which randomly were divided into 5 groups including the control group, group receiving 200 mg/kg oral aspirin, group receiving 200 mg/kg aspirin as I.P, group receiving 100 mg/kg vitamin E pre oral aspirin administration, and group receiving 100 mg/kg vitamin E pre I.P administration of aspirin groups. Ulcers were evaluated by J. Score method (reported as J.Score±S.E.M.t student), and ANOVA was used for data analysis. Results: J. Score of IP administration of aspirin was 18.83±0.5 and then J. Score of oral administration of aspirin was 16.1±0.6 , J. score of vitamin E ± I.P administration of aspirin was 8.6 ± 0.3 and finally J. score of vitamin E±oral administration of aspirin was 7.3±0.4. Significant decrease was considered in ulcers in groups in which oral vitamin E administrated pre aspirin administration (P< 0.05). Conclusion: Vitamin E decreased aspirin induced gastric ulcers via antioxidant effects. SOURCE: URMIA MED J 2015: 26(7): 549 ISSN: 1027-3727
