Abstract

Background: Diabetes mellitus is a metabolic disorder and one of its most important consequences is renal insufficiency. A multitude of herbs has been described for the treatment of diabetes mellitus. The aim of present study was to assess the protective effect of turnip root ethanolic extract (TREE) on early nephropathy in alloxan-induced diabetic rats.

  Materials and Method: Eighty male Wistar rats were randomly allocated into 4 equal groups including: healthy rats, normal healthy rats receiving TREE, diabetic rats and diabetic rats receiving TREE. Diabetes was induced by a single injection of alloxan (120 mg/kg i.p). The extract (200 mg/kg) was gavaged to TREE treatment groups daily for 8 weeks. At the end of experiment serum levels of urea, uric acid and creatinine were assessed. The lipid peroxidation product, thiobarbituric acid-reacting substances (TBARS), and activities of superoxide dismutase, catalase and glutathione peroxidase were measured in the renal tissue. Finally, the biochemical findings were matched with histopathological verification. Statistically, the quantitative data obtained, compared among the groups by one-way analysis of variance followed by Tukey post-test. Statistical significance was considered at p<0.05.

  Results: In the diabetic rats, TREE significantly decreased the levels of serum biomarkers of renal injury. Furthermore, TREE significantly decreased the lipid peroxidation and elevated the decreased levels of antioxidant enzymes in diabetic rats. Histopathological findings were in agreement with the biochemical findings.

  Conclusion: TREE has protective effect on early diabetic nephropathy in the rats with experimentally induced diabetes.
