Oxidative stress plays a key role in the evolution of diabetes complications. The current study looked into the potential effects of the hydroalcoholic extract of Nigella sativa on the oxidative injury of the rat kidneys in diabetic animals. The animals were placed into five study groups in a random manner as follows: (1) control, (2) diabetic, (3 and 4) treatment with two doses of N. sativa extract (200 and 400 mg/kg), and (5) treatment with metformin (300 mg/kg). The time course of administration was six weeks. The malondialdehyde (MD A) and total thiol groups, as well as the superoxide dismutase and catalase activities, were also assessed in the renal tissue and lipid profile in serum. In the diabetic groups, the level of MDA significantly increased (P < 0.01) and antioxidant levels decreased compared to the control (P < 0.05). In treated rats with N. sativa, the antioxidant status of renal tissue was improved (P < 0.05 to P < 0.001). The lipid profile also improved in the rats treated with the extract (P < 0.001). Our findings suggest that long-term administration of N. sativa in diabetic rats induced by streptozotocin can improve the status of the oxidative stress in kidney tissue.
