- Sperm chromatin dispersion 精子染色质扩散
- 6 hours after pollination,the sperm chromatin disperses thor-oughly in the egg nucleus,and finally the sperm chromatin and the eggchromatin can not be distinguished. 授粉后6小时,精核的染色质在卵核内分散,最后精核染色质和卵核的染色质不能区分。
- Objective To investigate the relationship between the results of sperm chromatin structure assay (SCSA) and the outcome of unexplained abortion and infertility. 目的探讨女方不明原因流产和不明原因不孕与其配偶精子染色质性状之间的关系;
- Methods The SCSA explores the metachromatic properties of acridine orange (AO) and flow cytometry to monitor the susceptibility of sperm chromatin DNA to acid induced denaturation in situ because of the low pH treatment. 方法利用吖啶橙的异染性和流式细胞术检测精子染色质DNA对原位酸诱导变性的敏感性。
- Micrococcal nuclease treatment indicates that the remodeling of the demembranated sperm chromatin has occurred and the structure of nucleosome is formed during nuclear reconstitution. 同时，利用小球菌核糖核酸酶处理的结果表明，去膜精子在此非细胞体系中发生了结构改建并且在重建过程中形成了核小体结构。
