本文主要对氯丁二烯、二硫化碳、二甲基甲酰胺、二甲基乙酰胺、甲醛等工业毒物致胚胎作用的研究方法和评价中存在的一些问题进行讨论。等1976年指出,在研究毒物的致胚胎作用时,必须考虑观察母体的特殊反应,这对确定毒物的选择作用具有重要意义。在孕期中,由于毒物的作用可能使母体对有害因素的敏感性增高,或使母体产生耐受性。作者根据实际生产中的情况和动物实验资料认为,在研究中不仅应考虑在整个孕期中胚胎对毒物作用的敏感 This article mainly discusses the research methods and evaluation problems of embryos caused by industrial toxicants such as chloroprene, carbon disulfide, dimethylformamide, dimethylacetamide and formaldehyde. In 1976, pointed out that in the study of toxic embryos caused by the role, we must consider the observation of the mother’s special reaction, which determine the choice of toxic effects of great significance. In pregnancy, due to the role of poison may make the maternal increased sensitivity to harmful factors, or make the mother tolerated. According to the actual situation in production and animal experimental data that in the study should not only consider the entire embryo during the toxic effects of the sensitive
