Abstract

Colonic tumors were induced in male Sprague-Dawley rats by ten applications of 2 mg/kg/week N-nitrosoacetoxymethyl-methylamine (AMMN) or by three applications of 100 mg/kg/month 1,2-dimethylhydrazine (1,2-DMH). Application of AMMN and 1,2-DMH induced selective colonic tumors in 97% and 29-42% of the initial animals, respectively. Colonic-tumor-bearing animals were subjected to monotherapy with 5-fluorouracil, ftorafur, CGP 6809, and CGP 15'720A. No cures were achieved. The different therapies did not exert any clear influence on the survival time of animals, except for animals pretreated with AMMN and then subjected to ftorafur therapy.

摘要

通过每周10次给予2 mg/kg的N-亚硝基乙酰氧基甲基甲胺(AMMN)或每月3次给予100 mg/kg的1,2-二甲基肼(1,2-DMH),在雄性Sprague-Dawley大鼠中诱发结肠肿瘤。给予AMMN和1,2-DMH分别在97%和29%-42%的初始动物中诱发了选择性结肠肿瘤。对荷结肠肿瘤动物进行5-氟尿嘧啶、替加氟、CGP 6809和CGP 15720A的单一疗法治疗。未实现治愈。除先用AMMN预处理然后接受替加氟治疗的动物外,不同疗法对动物的生存时间没有明显影响。
