Germinated rough rice (GRR) has many healthy effects such as antioxidant activity, inhibition of chronic inflammatory disease and prevention of vascular disease. In this study, germinated Korean rice sample which was planted in 2008 from Korean Rural Development Administration was used. The purpose of this study was to recognize the effect of the ethanol extract of GRR on the ischemic damage of skeletal muscle. Right femoral artery ligation was performed to induce ischemic condition in mice and the mixed basal diet with the ethanol extract of GRR at various levels (100, 200, and 400 mg/kg diet) was given for 2 weeks. After the mice were sacrificed, the hind limb muscle samples of the mice were fixed, sectioned, stained with Haematoxylin-Eosin (H&E), Masson’s trichrome, and performed for Immunohistochemistry (IHC) for caspase-3. In histopathological findings of H&E and Masson’s trichrome stain, the treatment of GRR at the level of 400 mg/kg diminished fibrosis and necrosis in the muscle compared to the control. The expression of caspase-3 protein was also decreased by the treatment of GRR at the level of 400 mg/kg compared to the control. These results suggest that the ethanol extract of GRR may have a protective effect against muscle damage during the ischemia in skeletal muscle of hindlimb.
