Inhibition of N-butyl-N-(4-hydroxybutyl) nitrosamine-induced urinary bladder tumor in rats by alpha-difluoromethylornithine. 1987

M Kawahara, and T Matsuhashi, and T Yagishita, and M Tajima, and M Matsushima

The therapeutic effects of alpha-difluoromethylornithine (DFMO) on rats with bladder tumors induced by N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) were examined. Eight-week-old male Wistar rats were given 0.05% BBN in their drinking water for a period of 4 weeks. Therapy (0.1% DFMO in their drinking water) was started at week 4 and all rats were killed at week 60. DFMO was seen to significantly reduce the incidence, the mean number and the total size of tumors. No side-effects of DFMO were noted, except alopecia, which started at month 7 of the therapy.
