促进作用

In this section, we focused on the investigation of the condensation, Michael reaction of different aromatic aldehyde with different aryl substituted ketones under solvent-free and PTC conditions, obtained polysubstitutedcyclohexanol derivatives in mordent yield when using TBAB as the catalyst.

通过实验发现，TBAB对该反应具有良好的促进作用，使在液相中需十几个小时甚至几十个小时才能完成的反应，在无溶剂条件下几分钟就可完成，并且使液相中两步完成的反应，而在无溶剂条件下一步就可完成，且产率优良。

The results show that GSH can improve the development rate of morula or blastocyst (32.84%),and rate of blastocyst (26.35%).

Results:LIF improved the development rate of early embryo at the concentration of 0.1,1 and 10ng/ml(P.05).The enhanced effects of LIF were significant for morula and blastocyst stage,not for 1～8 cell stage of embryos.Conclusion:LIF may improve the development of early mouse embryos at the appropriate concentration.

结果：①0.1ng/ml、1ng/ml和10ng/ml浓度的LIF对小鼠早期胚胎的发育和胚泡的形成有促进作用，0.01ng/ml和100ng/ml浓度的LIF对胚胎的发育无明显影响；②LIF对小鼠早期胚胎发育的影响主要发生于桑椹胚和胚泡期，对1～8细胞期胚胎无明显影响。
