1人精子活力试验在IVF实验室质量控制中的应用显示文摘目的:评价人精子活力试验作为体外授精-胚胎移植(IVF)实验室质量控制方法的敏感性及应用价值。方法:实验1实验组HTF培养液中加入0.25%、0.75%的甲醛,对照组不加甲醛;所有HTF培养液均加入0.3%牛血清白蛋白、矿物油或者两者都有,了解人精子活力在这些培养条件下的变化。实验2采用人精子活力试验检测3种组织培养管的胚胎毒性。在HTF培养液中加入牛血清白蛋白、矿物油或两者都加,对照组不加任何附加物,了解这些附加物对精子有无保护作用。结果:实验1人精子在含0.25%甲醛的HTF培养液中培养24 h,活力指数为0.594±0.331,高于含0.75%甲醛培养液的0.450±0.284,差异有统计学意义(P<0.01);在含0.25%和0.75%甲醛的胚胎培养液中加入0.3%牛血清蛋白、矿物油,精子活力指数分别为0.683±0.334、0.527±0.345,高于不含牛血清白蛋白及矿物油的0.394±0.311、0.424±0.311,差异有统计学意义(P<0.01)。实验2同样的培养时间与培养条件,丹麦Nunc lom公司7 m l组织培养管中的精子活力指数为0.677±0.335,高于美国Falcon公司的14 m l培养管的0.596±0.327和美国Corn ing公司15 m l组织培养管的0.551±0.317,差异有统计学意义(P<0.01);在培养液中加入0.3%牛血清白蛋白、矿物油,精子活力指数为0.821±0.259、0.645±0.335,高于不含牛血清白蛋白及矿物油的0.571±0.321与0.395±0.245,差异有统计学意义(P<0.01)。结论:精子对培养环境中的微量毒性成分十分敏感,其活力在短时间内明显下降。人精子活力生物试验是一种敏感的生物测试方法;丹麦Nunc lom公司7 m l组织培养管对精子活力影响最小,适合于人胚胎的培养;培养液中加入牛血清白蛋白及矿物油可以减少培养环境中的毒素影响,对精子及其活力有保护作用。蔡霞 Kimball O Pomeroy John H Mattox 2006中华男科学杂志2006,12,7:4

3中国资本管制的效率和影响显示文摘随着全球经济的发展,世界各国更加紧密地通过商品和服务贸易、资金流动以及相互投资联系在一起。但是,一方面是越来越多的国家通过放松对国际贸易的管制来刺激经济的快速发展,另一方面,则除了发达国家之外,其他各国仍存在着对资本流动的管制。我国也是如此,无论在深度还是广度上对跨国资本流动都有严格管制。肖凤娟 杨卓心 Donald Kimball 2006中国外汇2006,,11:2
