摘要: 作者研究观察了亚硝酸钠和N - 甲基苄胺的遗传毒性作用。结果表明,亚硝酸钠和N - 甲基苄胺不产生急性遗传毒性( P > 0. 5) ,但具有中长期遗传毒性。长期接触可诱发大鼠胃窦及食道上皮的增生性病变,使胸腺指数降低,骨髓细胞MN ‰升高。

Abstract: The genotoxicity of sodium nit rite and N-methylbenzylamine were detected. The result s showed that sodium nit rite and N2methybenzylamine did not induce acute genotoxicity ( P > 0. 5) ,but had a middle and long term genotoxicity. Exposed for long term , the gast ric ant rum and exophagus in the rat s showed different levels hyperplastic change ; and the per mil rate of micronuclei of marrow cells increased ; the thymus gland indexes lowered.

Key words: Sodium nit rite, N-methylbenzylamine, genotoxicity
