环境诱变剂

环境诱变剂诱变的家蚕核型多角体病毒继代实验及诱变病毒基因组的酶切分析

The Successive Test of the Environmental mutagen mutated Bombyx mori Nuclear Polyhedrosis Virus and the Restriction Analysis of Its Genome

采用被公认的环境诱变剂检测方法之一的Ames试验方法，来研究昆虫病毒的致突变性。

The mutagenicity of insect virus was studied by using Ames Test which is one of the recognized examination method of environmental mutagen .

双链DNA直接测序法在环境诱变剂致突变分子机制研究中的应用Ⅰ.非突变质粒抗性基因片段的序列测定

Application of directly sequencing for double strand DNA in research of enviromental mutagens

同样地，环境诱变剂诱发的细胞应答反应也不只是单纯地由DNA损伤所触发的。

Similarly , the cellular response to the environmental mutagens is not always initiated by DNA damage .

在氟化钠、重铬酸钾、丝裂霉素C和秋水仙素等四种环境诱变剂作用下，以上倾向没有变化；

The difference did not change even under the action of sodium fluoride , potassium bichromate , mitomycin C and colchicine .

本实验表明：双链DNA直接测序法可应用于环境诱变剂研究。

The results showed that the method directly sequencing for double stranded DNA is useful to the study of environmental mutagens .

蚕豆SCE检测环境诱变剂的方法学研究

Study on Method of Sister Chromatid Exchange in Vicia faba to Detect Environment Mutagen

但是环境诱变剂引起的突变也可发生在非DNA损伤部位，它被称之为非定标性突变（nontargetedmutagenesis）。

However , environmental mutagens can also induce mutations at undamaged sites and result in the so-called nontargeted mutagenesis .

SCE频率分析是研究环境诱变剂和致癌剂引起人类遗传物质损伤的有效手段。

The analysis of Sister Chromatid Exchanges ( SCE ) frequencies is a useful tool for the study of damages in genetic material of human beings induced by environmental mutagens and carcinogens .

环境诱变剂对人血红细胞膜蛋白巯基结合位置性质的影响

The effects of Environmental Mutagens on the properties of human erythrocyte membrane protein sh binding site

车间环境诱变剂的紫露草微核原位监测的应用研究

Applied research on Tradescantia micronucleus ( tradmcn ) for in situ monitoring of environmental mutagens in workshops

在Trad－MCN分析中，以微核率作指标来判断环境诱变剂对染色体的损伤程度和诱变剂强弱一直沿用至今。

In Trad-MCN test the micronucleus rate has been adopted as the only index to assess the extent of damage to plant chromosomes by mutagens .

实验结果表明，这种带不等长染色单体的标记染色体，是用生殖细胞研究环境诱变剂遗传毒理学效应的有用手段。

These findings , therefore , indicated that marker chromosomes with unequal-length chromatids in translocation heterozygotes may be a useful indicator for detection of the cytogenetic effects of environmental mutagens on germ cells .
