卵裂

Following 72 h co-culture, desquamate, sporozoites, trophozoites, meronts, microgametocytes, macrogametocytes, zygote, thin-wall oocyst, and thick-wall oocyst appeared orderly. Between the 60th and 72th hour, many oocysts emerged. Inoculated by the C. parvum -infected cell culture supernatant at the 48th hour, the immunosuppressed mice became infected.

The results were as follows:The first, there were significantly differences percent between 0.6μg/mlgroups and other three groups (0.2μg/ml groups, 0.4μg/ml groups and 0.8μg/mlgroups) in 2 hour groups; and there were significantly differences between0.4μg/ml groups and other three groups in 4 hour groups; and there weresignificantly differences between 0.6μg/ml groups and other three groups in 6hour groups; and there were significantly differences between 0.4μg/ml groupsand other three groups in 8 hour groups on the metaphases (P＜0.05), in theexperiment of the effect on the mouse 4- cell embryo stage single blastomere ofcolchicine with different concentrations and duration, by x~2 statistical analysis.

实验结果如下：1、在确定秋水仙素不同处理浓度和时间对小鼠4-细胞期胚胎单卵裂球中期分裂相数影响的实验中，经统计分析，阻断培养2小时组中0.6μg／ml浓度组与其他三组差异显著(0.2μg／ml组、0.4μg／ml组和0.8μg／ml组)；阻断培养4小时组中0.4μg／ml浓度组与其他三组差异显著；阻断培养6小时组中0.6μg／ml浓度组与其他三组差异显著；阻断培养8小时组中0.4μg／ml浓度组与其他三组差异显著(P＜0.05)。

But the latter resulted in significantly more zygotes extruded PBl and developed to blastocyst stage after parthenogenetic activation.

结果发现，成熟液中添加促卵泡素组的卵裂率(74.3％)低于人绝经促性腺激素组(78.6％，P＜0.05)，但是第一极体排出率和孤雌激活后的囊胚率都显著高于hMG组(P＜0.05)。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
