Objective: The objective of this study was to investigate the effect of silymarin extract from Silybum marianum against nickel-induced alterations in haematological indices, kidney dysfunction and renal antioxidant defence system.

Methods: Male albino Wistar rats were divided into four groups seven each. Control, silymarin, nickel and nickel plus silymarin. Silymarin was administrated orally (100 mg/kg b. wt) and nickel as nickel sulfate (NiSO4 6H20) was given intraperitoneally (20 mg/kg b. wt) at alternative days. The experiment continued for three consecutive weeks. Body weight was recorded regularly. After overnight fasting, animals were killed and serum creatinine, serum urea, serum uric acid, hematological parameters and renal antioxidant markers were determined.

Results: The treatment with nickel led to a significant decrease in body weight with an increase in both absolute and relative kidney weights and a significant increase in renal markers, which confirmed by histopathological alteration. A microcytic anemia was also observed, which was manifested by a reduction of red blood cells count (RBC), hemoglobin (Hb) concentration, platelet counts (Plt), hematocrit and white blood cells counts (WBC). The level of lipid peroxidation was increased. Whereas, GSH concentration and enzymatic antioxidants SOD, GSH-Px and CAT activities were decreased. The co-treatment with methanolic extract of milk thistle attenuated the variation in the hematological and renal markers, decreasing renal lipid peroxidation (p<0.05) with a concomitant increasing reduced glutathione content (p<0.01) and restoring the antioxidant enzymes (SOD, CAT, GSH-Px) in kidney, as well as an improvement in histological changes compared to those previously noticed in nickel group.

Conclusion: To conclude, these findings demonstrated that silymarin extract effectively improved heamatotoxicity and nephrotoxicity caused by nickel.
