title: Neoplasms of urinary bladders of hamsters treated with 2-acetylaminofluorene and indole.
abstract: Tested in hamsters was the effect of neonatal treatment with 2-acetylaminofluorene (AAF) followed by prolonged feeding in combination with indole on the development of bladder tumors. Neonatal males and females were given intraperitoneal injections of AAF, 5 mg/100 g body weight, 3 times weekly until weaning. They were then fed a synthetic diet containing 0.06% AAF and 1.6% indole. The 26 hamsters surviving 10-12 months developed transitional cell carcinomas of the bladder, all but 2 of which were invasive. No hamsters had malignant tumors in the liver. Seven hamsters developed peliosis of the spleen.
