Studying the antioxidant role of mushroom against hazards of gamma radiation exposure in male rats

This study aimed to investigate the antioxidant role of dried mushroom (DM) against hazards of gamma-irradiation in male rats. In this study, exposure of rats to whole body g-radiation (6 Gy) resulted in hepatic oxidative stress (a significant increase in lipid peroxidation concomitant with a significant decrease in glutathione content and antioxidant enzyme activities); increase liver function enzymes and histopathological disorders. Treatment of irradiated rats with 10% DM significantly improved radiation-induced injury as indicated by the reduction of the indices of liver damage, lipid peroxidation product, the elevation of antioxidants and the attenuation of the tissues histological architecture. These results suggest that oyster mushroom can improve the antioxidant status and minimize the occurrence of oxidative stress- associated disorders.
