Rats in the S and IR groups were intragastrically administered with warm water every day. After 1 week, the kidney IRI rat models were prepared, after which the rats were fed for another week, and blood, urine, and the kidney tissue specimens were retained. A series of biochemical indices, superoxide dismutase(SOD), and malondialdehyde in the serum and kidney tissues were detected, and pathological changes in renal tissue were observed.Results Twenty-four-hour urinary protein excretion, urinary NAGase, Cys C, blood urea nitrogen(BUN), and creatinine were significantly lower in the P + IR1 and P + IR2 groups than in the IR group(P < 0.05). Superoxide dismutase in the serum and renal tissue increased significantly, malondialdehyde decreased significantly(P < 0.05), renal pathological injury was alleviated, and the kidney index improved significantly(P < 0.05).Conclusion Probucol can relieve various types of acute renal failure in postoperative rats.展开更多
