Abstract

Introduction: Morus nigra fruit is known to have antioxidant effects and used to control the blood sugar level in traditional medicine. Objectives: This study was conducted to investigate the biochemical and histopathological changes in the serum and kidneys of diabetic rats treated with hydroalcoholic M. nigra extract. Materials and Methods: In this study, 60 male Wistar rats were divided into five groups of 12 each. After induction of diabetes with alloxan, the diabetic rats were treated with hydroalcoholic extract of M. nigra at different concentrations. Then, the animals were anesthetized and the serum levels of glucose, creatinine, and urea as well as kidney tissue catalase level measured. The kidney tissue was also histopathologically examined. Results: Milder glomerular damage was seen in the group treated with 800 mg/kg of the M. nigra extract compared with diabetic and positive controls, and no difference in the expansion of mesenchymal tissue into renal glomerular vessels observed between the group treated with 800 mg/kg of M. nigra extract and diabetic and positive controls. Furthermore, creatinine levels were significantly higher and urea levels significantly lower in the group treated with 800 mg/kg of M. nigra extract than healthy and positive control groups (P<0.05). Conclusion: Administration of M. nigra extract at 800 mg/kg can prevent kidney tissue damage in diabetic rats and this fruit seems to be beneficial to patients with diabetes.
