Oxidative stress is a biological entity quoted as accountable for several pathological conditions including diabetes mellitus. Chronic hyperglycemia in diabetes is associated with oxidative stress mediated tissue damage. The present study was designed to explore the role of isoflavones in ameliorating hyperglycemia-mediated oxidative damage to liver in alloxan induced diabetic rats. Alloxan was administered as a single dose (120 mg/kgBW) to induce diabetes while isoflavones (2 mg/ kg BW) was orally administered daily to alloxan-diabetic rats for four weeks. In addition to the levels of blood glucose, plasma insulin, the extent of oxidative stress was assessed by hepatic lipid peroxidation. The level of reduced glutathione and the activities of enzymatic antioxidants were determined in the liver tissues. The activities of serum aminotransferases and alkaline phosphatase were assayed. A portion of liver was processed for histological examination. Oral administration of isoflavones to diabetic rats decreased the levels of blood glucose and increased the plasma insulin level. A reduction in thiobarbituric reactive substances was observed. The diminished activities of antioxidant enzymes and reduced glutathione in diabetic rats were improved upon isoflavones administration. Thus, the results of the present study indicate that isoflavones treatment protects the hepatocytes by improving the antioxidant competence in hepatic tissues of diabetic rats which is further evidenced from histological examination.
