The production efficiency of tansgenic animal by the traditional method of pronucleus microinjection is very low (The efficiency of transgene is about 3～5%).

以传统的原核显微注射法生产转基因动物的效率非常低下（成功率仅为3~5%），严重地制约了转基因动物研究进展。

The results show that FISH can be used in experimental study and clinical application of PGD; 3. The cause of multi- pronucleus in embryos from IVF or ICSI would be different.

IVF受精和 ICSI受精的3PN胚胎发育有差异，证明＊F受精和 ICSI受精的3PN中的原核的来源是不同，导致胚胎第一次卵裂的方式也不同。

Transgenic mice carrying human renin gene were generated by means of pronucleus injection.

To make the transgenic mice: We purified the gene fraction nestin-hsp68-EGFP and injected it into pronucleus of mouse zygotes to generate the transgenic mice.

1。转基因小鼠的获得：纯化基因片段nestin-hsp68-EGFP，用显微注射方法把基因片段注射到受精卵的雄原核中，获取转基因小鼠。

PCR-SSCP (single-strand conformation polymorphism) was used for studying the community changes of pronucleus microorganisms in various fermenting stages of Luzhou-flavor Daqu. The results showed:(1) The pronucleus microorganism's community was similar and also had the polymorphism in each simple of various fermentation stage;(2) Different microflora had complex ecology effects of coordination and the restriction;(3) The diversity indexes of different stage of Daqu microorganisms were around 1.69~2.01, and the composition of them was stable relatively;(4) The similarity indexes were 0.67~1.00, and much higher in the approaching stages.

采用PCR-SSCP技术对浓香型大曲发酵过程中原核微生物群落结构的变化情况进行了研究，结果表明：(1)发酵各时期曲样的群落结构相似，同时也具有多态性；(2)不同微生物群落具有协同和制约的复杂生态学效应；(3)各时期曲样微生物多样性指数均在1.69~2.01之间，群落结构相对较稳定；(4)各曲样微生物群落相似性位于0.67~1.00之间，邻近时期样品间的相似性程度较高。
