The study on the mutagenecity of environmental chemicals in human germ cells is an im portant subject. In 1975 Rudak and his colleague developed a method for analysing human sperm chromosomes. Using interspecific in vitro fertilization of human sperms and zone-free golden hamster oocytes, the human sperm metaphase chromosome slides were prepared. The last decade, a total of 21390 human sperm karyotype from about one hundred and more normal males were analyzed. The mean frequencies of structural aberration and aneuplo-id were 11.5% and 1.4% respectively. The frequency of human sperm chromosome aberration shown a significant and dose-dependent increase after treating in vitro with radiation. Martin and others found a significant and persistant increase in the frequency of sperm chromosomal aberrations after radiotherapy and/or chemotherapy in 18 cancer patients. The analysis method of human sperm chromosome complement could be used to monitor the mutagenecity of environmental chemicals in human germ cells ( sperms ).

环境化学物质对人类生殖细胞的诱变作用研究甚少,但其意义重大,因为生殖细胞的遗传损伤有可能对下一代产生不良影响。1978年Rudak等人利用去透明带金黄地鼠卵与人精子在体外异种受精,获得人精子染色体中期相标未,建立了人精子染色体分析方法。十年来共分析100多位正常人21390组精子染色体核型,平均结构染色体畸变率为11.5%;非整倍体率为1.4%。人精子在体外经辐射线(X线等)照射后,染色体畸变率明显升高,与剂量呈线性关系。martin等人观察了18名经放疗/化疗以及经化疗后的肿瘤患者,治疗后精子染色体畸变率亦明显升高,且在数年至十多年后仍高于正常人。人精子染色体分析方法可用于环境化学物质对人类生殖细胞(精子)诱变作用的监测。

迄今,氟化物在体内、外的遗传毒性生物测试系统中所得的结果不尽一致,仍存在争论。本实验进行了氟化钠的果蝇伴性隐性致死交变研究,成年OK品系雄蝇被饲予含72、144和288PPNaF(分别相当于1/8、1/4和1/2LC50)的2%蔗糖液,连续48小时。结果表明288PPNaF组的总致死率达0.59%,与溶剂对照组之间存在显著性差异(P<0.05).同时,各浓度组间也有肯定的剂量一效应关系。上述观察结果提示NaF为一弱致突变物,对人类生殖细胞可能具有潜在的遗传毒性作用,因此,必须作进一步研究,以确定氟化物的此种作用。

Using the zona-free golden hamster eggs. We induced and analyzed the human sperm chromosomes from 23 males who have been smoking for 5 to 14 years, 1379 haploid metaphases were observed, in which 32 metaphases were structural aberration, and 69 numerical aberration the abnormal ratio being 7.32%. This ratio and that of the control group when compared showed a statistical difference (P<0.05).

采用人精子与去透明带的金黄地鼠卵离体受精制备出人精子染色体标本,对23例吸烟5-14年的男性及23例无吸烟史的正常男性进行了精子染色体畸变率的统计学分析。结果显示正常对照组畸变率为4.13%,吸烟组畸变率为7.32%,两者经统计学分析P<0.05,各不同吸烟史小组与正常对照组畸变率比较均为P<0.05,本实验为进一步探讨吸烟为人类生殖细胞遗传物质的影响提供了参考数据。
