Abstract
Objective(s): Oxidative stress has a pivotal role in the pathogenesis of diabetic retinopathy (DR). Juglans regia L. (JRL) leaf extract has hypoglycemic and antioxidative properties. This study aimed to determine the ameliorative effects of JRL against diabetic retinopathy. Materials and Methods: The DR rat model was generated by injection of streptozotocin (STZ). A subset of the diabetic rats received JRL or metformin after the onset of hyperglycemia. Histopathology and immunohistochemistry of apoptotic and inflammatory factors were assessed along with biochemical assessments of lipid peroxidation and antioxidant status. Results: Lipid peroxidation level and catalase activity significantly improved after JRL consumption (PPP Conclusion: JRL leaf extract exert protective effects against diabetic retinopathy.
