Effects of promoters on N-butyl-N-(4-hydroxybutyl)nitrosamine-induced urinary bladder carcinogenesis in the rat.
It has been shown that the occurrence of the preneoplastic lesion, papillary or nodular hyperplasia (PN hyperplasia) in rat urinary bladder induced by carcinogens is correlated with that of cancer. Therefore, the promoting effects of chemicals in two-stage bladder carcinogenesis were judged by measuring their ability to induce PN hyperplasia in rats. Male rats were given N-butyl-N-(4-hydroxybut...
متن کاملStrong promoting activity of reversible uracil-induced urolithiasis on urinary bladder carcinogenesis in rats initiated with N-butyl-N-(4-hydroxybutyl)nitrosamine.
The tumor-promoting effect of uracil-induced calculi on rat urinary bladder carcinogenesis was investigated in male F344 rats pretreated with N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN). Since uracil-induced calculi and papillomatosis of the bladder are reversible, uracil was given for a limited period after the treatment with BBN. Animals were given 0.05% BBN in their drinking water for 4 wk a...

متن کاملChemopreventive effects of silymarin and silibinin on N-butyl-N-(4-hydroxybutyl) nitrosamine induced urinary bladder carcinogenesis in male ICR mice.
Effective strategies are lacking for the management of urinary bladder cancer for which smoking is a potential risk factor. Herein, we evaluated chemoprevention of urinary bladder cancer by natural chemopreventive agents, silymarin and silibinin, in a preclinical animal (ICR mouse) model of bladder cancer induced by tobacco smoke carcinogen N-butyl-N-(4-hydroxybutyl) nitrosamine (OH-BBN). Mice ...
متن کاملDNA study of bladder papillary tumours chemically induced by N-butyl-N-(4-hydroxybutyl) nitrosamine in Fisher rats.
To examine DNA abnormalities in bladder papillary tumours induced by N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) in female rats, using image cytometric DNA analysis and cytogenetics. Thirty female rats were exposed to BBN in their drinking water for 20 weeks. One group of 10 animals served as controls. The animals exposed to BBN were killed at a rate of two per week, with the bladder being col...
