2012/4/13
目的探讨不孕症患者接受体外受精/卵细胞质内单精子注射（IVF/ICSI）-胚胎移植治疗获得妊娠后发生早期流产的相关因素。方法回顾性分析笔者医院生殖中心2008年6月~2009年12月间经IVF/ICSI治疗获得临床妊娠的331例患者，按妊娠结局分为早期流产组及继续妊娠组；分析受精方式、年龄、既往自然流产史、移植后12天血β-HCG值、孕囊数及不孕原因与早期流产率的关系。 结果IVF、ICSI两种受...
小鼠植入前胚胎的发育过程中， 核仁经历从简单到复杂、从致密结构到网状结构的变化。对核仁超微结构的观察有助于揭示早期胚胎发育过程中核仁结构的动态变化及其特定阶段的功能。但由于核仁结构微小， 数目较少， 并且在胚胎中只处于卵裂球细胞核的内部， 难以定位， 因而给核仁的超微结构观察带来很大的困难。本实验探索了透射电镜观察小鼠植入前胚胎核仁的方法: 先用琼脂对小鼠胚胎进行预包埋， 在经过常规的透射电镜样品...
