RESUMO
BACKGROUND: Cisplatin (CP) is widely used in clinic to treat the solid tumors. However, CP is associated with some major side effects including nephrotoxicity, hepatoxicity, and testicular toxicity. OBJECTIVES: To found, which of the toxicities is the first side effect of CP. MATERIALS AND METHODS: we conducted a pilot research on 12 adult male Wistar rats. RESULTS: One week after CP administration, the induced toxicity was observed clearly in kidney tissue. The only abnormality that observed in testis tissue was very small degree of hyaline casts. However, no damage and other abnormality were detected in the liver tissue. CONCLUSIONS: According to these findings, in clinic, first special attention must be made on kidneys during chemotherapy with CP. However, the duration of experiment is suggested to be extended to obtain hepatoxicity or testicular toxicity model in experimental animal in laboratories. Moreover, different dose of CP should be used to study the first side effect in animal model.
