We choose abortus of three to six months old as research object. In the research, we collected 35 specimen that all came from induction of labor with water bag. We successfully culture OECs from human embryo olfactory bulb by using primary culture.

一、人胚胎嗅神经鞘细胞的体外培养本研究共收集标本35例，均为3—6个月的水囊引产流产儿，采用原一代培养的方法，自人胚胎的嗅球培养出OECS。

The protocol for the detections of all the AIV isolates, the H5-subtype and the optimization of reactions were studied with a H5-subtype reference isolate BSG1. A 229bp-band of AIV specific and a 380bp-band of H5 subtype specific were amplified individually with the designed primers of AIV specific and H5-subtype specific respectively by the developed RT-PCR technique from isolate BSG1. A double-PCR was also developed which can detect all the AIVs and identify the H5-subtype AIVs. The results of specificity experiment showed that there was no specific band could be amplified with the samples of Newcastle disease virus, infectious bronchitis virus, infectious laryngotracheitis virus, egg drop syndrome virus and infectious bursal disease virus.

结果应用通用引物可从BSG1毒株扩增到与预计大小相符的229bp AIV特异性片段，应用H5亚型鉴定引物则可从BSG1毒株扩增到与预计大小相符的380bp H5亚型特异性片段；在此基础上建立了可检测所有AIV毒株以及可同时进行H5亚型毒株鉴定的二重RT-PCR方法；检测方法的特异性试验结果表明，该方法对新城疫病毒、传染性支气管炎病毒、传染性喉气管炎病毒、产蛋下降综合症、传染性法氏囊病毒无交叉反应；检测方法的敏感性试验结果表明，通用引物扩增、H5亚型特异性引物扩增以及二重PCR扩增反应的组织样品总RNA的最低检出量分别为0.0217μg、0.0217μg和2.17μg；对20份临床样品检测中，有10份为AIV阳性，其中有5份为H5亚型病毒阳性。

Inthe present paper, we have systematically analyzed the biologicalproperties of the venoms obtained by dissecting poison glandsand electrical stimulation from Latrodectus tredecimguttatusindigenous to the some areas of the Xinjiang Uighur Autonomous Regionof China.

本实验采用解剖分离毒囊和电刺激方式采毒，对产于我国新疆的间斑寇蛛的粗毒的生物学活性做了较为详细的研究。

Type genus of Gleicheniaceae: leptosporangiate ferns with sessile sporangia; South Africa to Maylasia and New Zealand.

里白科的模式属；薄囊蕨，具无柄的孢子囊群；产于南非至马来西亚和新西兰。

A new method for enucleating MⅡ nucleus in mouse and rat was induced; Living births were obtained from IVF of mouse oocytes reconstructed by transfer of metaphase Ⅱ chromosomes. For the interspecies nuclear transfer between mouse and rabbit, the reconstructed embryos could develop into blasocyst in vitro.

在不同品系小鼠卵母细胞核质交换移植中将电融合的重构卵进行IVF，经胚胎移植后顺利产仔；在异种核移植方面，小鼠核与兔卵母细胞的异种重构胚在体外培养条件下发育至囊胚阶段。
