Results are expressed as the mean±SD (n=7). SOD: superoxide dismutase; GSH: glutathione; MDA: methane dicarboxylic aldehyde; LG: liver glycogen; NCG: normal control group; DCG: diabetic control group; MG: diabetic rats treated with Met (200 mg/kg); PSPE 50: diabetic rats treated with PSPE (50 mg/kg, oral); PSPE 100: diabetic rats treated with PSPE (100 mg/kg, oral); PSPE 200: diabetic rats treated with PSPE (200 mg/kg, oral).
