Tumorigenicity of isoniazid (INH) and hydrazine sulfate (HS) was studied in male and virgin Swiss mice. The INH and HS induced 50% und 84% lung tumors in males and 67% and 72% in females, respectively. Both chemicals induced lung tumors in animals of the F1 generation that were exposed to INH or HS during intrauterine life, lactation, and in the postweaning period. Surprisingly, the F2 generation from these F1 animals, which were exposed to INH only during gestation and lactation, showed earlier and much higher tumor incidence than the parent generation.
在雄性和未交配的瑞士小鼠中研究了异烟肼(INH)和硫酸肼(HS)的致瘤性。INH和HS分别在雄性小鼠中诱导出50%和84%的肺部肿瘤,在雌性小鼠中分别诱导出67%和72%的肺部肿瘤。这两种化学物质在子宫内生活、哺乳期和断奶后接触过INH或HS的F1代动物中都诱发了肺部肿瘤。令人惊讶的是,这些仅在妊娠和哺乳期接触过INH的F1代动物的F2代,其肿瘤发生率比亲代更早且更高。
