چکیده    Background: oxidative stress plays an important role in the pathogenesis of bleomycin-induced lung fibrosis and many antioxidant agents have been used for the treatment of this disease in animals. objectives: to evaluate the antioxidant effects of pomegranate seed extract (pse) on bleomycin treated rats. materials and methods: male spraque - dawley rats were divided into 5 groups: rats in groups i (bleomycin) and ii (control) were given a single dose of bleomycin (7.5 iu/kg,intratracheally) in the bleomycin group and same amount of saline in the control,respectively. treatment groups (iii-v) were given pse (100,200,400 mg/kg) orally a week before the bleomycin injection and this was continued for 3 weeks. at day 28,animals were sacrificed and lungs were removed for histological investigation. results: histological analysis showed that pse could prevent pathological changes that were seen in the bleomycin group. conclusions: results of the present study showed that hydroalcoholic extracts of pomegranate seeds had a significant protective effect against bleomycin-induced lung fibrosis by its antioxidant properties. the highest protective effect was observed for the 400 mg/kg dose. © 2013,school of pharmacy,ahvaz jundishapur university of medical sciences; published by docs.
