| 5. | Several studies have shown that so2 and its derivatives could induce chromosomal aberrations , sister chromatid exchanges and micronuclei in human blood lymphocyte , bone marrow cell in mice and chl 研究发现, so _ 2及其衍生物可引起人外周血淋巴细胞、小鼠骨髓细胞、中国仓鼠肺成纤维细胞等哺乳动物细胞的染色体畸变、姊妹染色单体交换及微核的形成。 |
| 6. | The aglycone , steviol , exhibited greater acute toxicity than stevioside in hamsters but not in rats . steviol was clearly genotoxic after metabolic activation , inducing forward mutations in bacteria and gene mutations and chromosomal aberrations in lung fibroblasts of chinese hamsters 甜菊醇经过代谢活化后,基因毒性明显,可引致细菌产生正向突变,以及使中国仓鼠的肺纤维原细胞产生基因突变和染色体变异。 |

| 8. | Several kinds of herbicides treating together show an antagonistic action also exist , even tend to intensify . the results also indicate that the inductive effect was weakened when 2 - ethy - 4 - chloro sodium hydration operated with other herbicides . nc - 302d ( + ) can evidently increase the frequencies of numerical and structural chromosomal aberrations 除草剂精禾草克试验组泥鳅染色体数目畸变率均有明显上升,有的组甚至与对照组差异极显著( p 0 . 01 ) ;各试验组染色体结构畸变率与对照组差异均极显著( p 0 . 01 ) 。 |
| 9. | Monofunctional alkylating agent n - methyl - n ' - nitro - n - nitrosoguanidine ( mnng ) is a widely spread environmental mutagen and carcinogen that targets dna and proteins to generate adducts . among the adducts , o6 - alkyl guanine is the predominant mutagenic lesion because of its mispairing properties , which can eventually lead to chromosomal aberrations , point mutations , and cell death . this lesion also appears to be involved in tumor initiation , particularly in gastric carcinogenesis 单功能烷化剂n -甲基- n -硝基- n -亚硝基胍( mnng )是一种在环境中广泛存在的化学诱变剂和致癌剂,它能和dna及蛋白质等生物大分子形成加合物( adduct ) ,其引起的与突变有关的主要dna损伤类型是o ~ 6 -甲基鸟嘌呤,这种损伤与肿瘤尤其是胃癌的发生密切相关。 |
