[Cisplatin nephrotoxicity: clinical observation and animal experiment].

Animal experiment and clinical observation were carried out to study the nephrotoxicity of cisplatin in order to give protective measures. In animal experiment it had been demonstrated that the nephrotoxicity induced by cisplatin was mainly related to the intraperitoneal concentration of cisplatin. The nephrotoxicity was permanent in rats treated with cumulative cisplatin. The main pathologic lesions were characterized by interstitial hyperemia, degeneration of the tubular cells and formation of tubular casts. In a Clinical study to compare two preventive methods (sodium thiosulfate and hydration) from cisplatin induced nephrotoxicity, the BUN and serum Cr were measured in 28 patients. The results revealed that there was no significant difference between the two groups (P greater than 0.05). The two protective measures had similar effect in reducing the nephrotoxicity of cisplatin. Five of 6 patients treated with cisplatin developed hypo-magnesemia but only one had symptoms.
