The effect of selenomethionine on the toxicity of cisplatin has been studied in mice and rats. When selenomethionine (0.5-4 mg kg-1) was administered intraperitoneally to mice 1 h before intraperitoneal cisplatin (6 mg kg-1), the toxicity of cisplatin, as measured by loss of body weight and blood urea nitrogen and serum creatinine levels, was reduced significantly. The protection was dose-dependent but less when given orally. Similar results were obtained with rats. Deterioration of renal function was characterized by reduced creatinine clearance, and increased excretion of urinary protein was significantly reversed. Partial but significant protection was also observed against capsulation-induced reduction of white blood-cell count. Protective properties were further demonstrated by increased survival of mice pretreated with selenomethionine compared with the lethality observed for animals given cisplatin only. These results suggested that selenomethionine protects against cisplatin-induced renal and other toxicity. The study has many clinical implications in cancer chemotherapy and needs further investigation.
