Histopathological studies on renal tubular cell tumors in rats treated with N-ethyl-N-hydroxyethylnitrosamine.
Administration of a diet containing 0.2% N-ethyl-N-hydroxyethylnitrosamine (EHEN) for 2 weeks induced hepatocellular carcinoma in 3 and renal tubular cell tumors in 7 of 9 Wistar rats. Diet containing 0.1% EHEN induced renal tubular cell tumors in 6 of 10 rats, but no hepatocellular carcinomas. Both diets induced atypical cell population of tubules in the kidney, but no nephroblastoma.
