Isolation and culture of osteoclasts: Osteoclasts were isolated and cultured from long bone cavities of human aborticide fetus.

Methods: Glutamine residue in 219 of trichosanthin was mutated into cysteine residue ( Q219C) by site-directed mutagenesis. The mutein was then modified by polyethylene glycol ( PEG). Ribosome-inactivating activity and abortifacient activity of the modified products were determined.

方法：利用定点突变将TCS第219位的天冬酰胺残基改变为半胱氨酸残基（Q219C）以供定点聚乙二醇（PEG）修饰，测定修饰产物的致核糖体失活活性及小鼠中期引产活性。

To study the mechanism of abortifacient effect of extract of Verbena officinalis ( VO), trophoblast cells from human placenta of 6 ￣ 8 weeks early pregnancy was isolated with Percoll method and cultured in vitro.

正常妊娠6～8周人绒毛滋养层细胞以Percol分离、纯化及体外培养为实验手段，观察马鞭草提取液对滋养层细胞功能的影响，进一步探讨了马鞭草抗早孕的细胞学作用机理。

There was no significant change in abortifacient activity by 5 000 PEG modification, whereas the activity was significantly enhanced when TCS was modified by 20 000 PEG.

相对分子质量为5000的PEG修饰对引产活性无明显影响，而相对分子质量为20000的PEG修饰却明显增强引产活性；
