Background: Diabetic nephropathy is a complex and multifactorial adverse effect of diabetes mellitus (DM). Crab shell as a natural product is supposed to have antioxidant effect which is one of the important mechanisms to improve DM. The aim of this study was to investigate the effect of crab shell extract (CSE) on the histopathology and antioxidant status of kidney in diabetic rats. Materials and Methods: Forty-two adult Wistar rats (210 ± 10 g) were divided into six groups (n = 7). Streptozotocin (50 mg/kg) was administered interaperitonealy (IP) for inducing diabetes. Rats were treated for 14 days by CSE with 100, 200, and 400 mg/kg doses IP. Fasting blood glucose, body, and renal weight were evaluated. The antioxidant status of kidney's tissue was evaluated by determining the level of ferric-reducing antioxidant power (FRAP). Furthermore, urine samples were used to determine nitric oxide (NO) levels. Microscopic slides were prepared to compare kidney histology between groups. Data were analyzed by one-way analysis of variance with post hoc Tukey's test, and P < 0.05 was considered statistically significant. Results: CSE induced a significant reduction in blood glucose (P = 0.01) and a significant increase in total antioxidant capacity (FRAP) (P = 0.004). Furthermore, urine NO was decreased significantly (P = 0.000). The extract improved renal tissue changes caused by diabetes. Conclusion: CSE improved antioxidant status and diabetic histological changes of rat kidney, and it could be an alternative complementary therapy in diabetic-associated disorders.
