We employed a cell line of mouse podocytes immortalized with the simian virus 40 large tumor antigen gene, and examined the cell proliferation using colony-forming and MTT assays following treatment with various concentrations of bFGF. BMP-7, alpha-smooth muscle actin e podocytes were detected by western blot. Methyl blue staining was used for the observation of cell morphology.

He results show that the virus regained infectivity, and the tannins did not direct viricidal effect. Tannins extracted from Polygonum perfoliatum or Archontophoenix alexandrae seeds showed strongly anti-TMV activities separately. TMV virions seems to be aggregated when TMV incubated with the tannins by electron microscope. It seems that TMV coat protein bind to the tannins based on PAGE. Tannins did not reduce infectivity when applied either before or after TMV inoculation. It is proposed that tannins extracted from the 11 species inhibited TMV by binding with TMV coat protein to interfere with recognition site essential for viral coat protein. Tannins extracted from Euphorbia hirta, P. perfoliatum, P. cuspidatum reduce infectivity when applied immediately in N.

MV分别与这11种植物单宁混合后，通过透析除去单宁后，可恢复大部分侵染力，表明单宁对病毒粒体并无直接毒害作用；TMV与杠板归和假槟榔种子中提取的单宁分别混合后，电镜下观察粒体呈现明显的聚集现象；TMV外壳蛋白分别与这两种植物单宁混合后，聚丙烯酰胺凝胶电泳中CP泳带滞后；单宁在病毒接种前施用未降低TMV对叶片的侵染能力；这些结果表明植物单宁对TMV抑制作用可能是单宁与TMV-CP结合影响病毒对叶片侵染位点的识别而降低TMV侵染性，而这种结合是可逆的。

To investigate the methods to effectively and simply assess the CAG repeat size of HD gene which was necessary for gene diagnosis of Huntington disease, the sequence including polymorphic CAG repeat of HD gene was amplified by PCR with TaKaRa LA Taq DNA polymerase and GC buffer. PCR products were analyzed on polyacrylamide gel to distinguish normal alleles from HD alleles. The DNA fragments of affected alleles were recovered from polyacrylamide gel as templets for secondary PCR. The secondary PCR products were cloned into T vector for sequencing analysis to determine CAG repeat size. A total of 20 normal individuals and 3 members from a HD pedigree were included in this study.

为了简单高效检测HD基因开放阅读框5'端n三核苷酸重复序列，建立快速准确的亨廷顿病(Huntington disease， HD)基因诊断方法，应用TaKaRa LA Taq DNA聚合酶配合GC buffer扩增HD基因包含n重复序列的目的片段，非变性聚丙烯酰胺凝胶电泳检测后回收n拷贝数异常增多的目的片段，再次PCR扩增后将产物连接至T载体，进行DNA测序确定CAG的拷贝数。
