Table 6: Level of liver reduced glutathione (GSH) and activities of superoxide dismutase (SOD), catalase (CAT) and Thiobarbaturic acid reactivesubstance (TBARs) in normal and experimental groups of rats. Values are given as mean ± SD for groups of eight animals each. *Significantlydifferent from normal group at p<0.01.SOD; one unit of enzyme activity was taken as the enzyme reaction, which gave 50% inhibition ofpyrogallol autoxidation in one minute/mg protein; CAT; μmol of H₂O₂consumed/min/mg protein;a: significant from normal control; b:significant from ferrous sulfate (30 mg/kg b.w.) supplement group; c: significant from cranberry extract (75 mg/kg b.w.); d: significant fromcranberry extract (150 mg/kg b.w.).
