Our previous studies have demonstrated that aqueous extract of Reishi (Ganoderma lucidum) occurring in South India possessed significant antioxidant activity. The present study was aimed at evaluating the radioprotective properties of the aqueous extract of this mushroom. Single-cell gel electrophoresis (comet assay), protection of radiation-induced plasmid pBR322 DNA strand breaks and inhibitions of lipid peroxidation (TBARS assay) were employed to determine the level of protection of­fered by the extract. The results indicate that aqueous extract of Reishi (Ganoderma lucidum) possessed significant radiopro­tective activity. The findings suggest the potential use of this mushroom extract for the prevention of radiation-induced cellular damages.
