RESULTS:①A total of 178 injected and survived zygotes were replanted. Thirteen mice were born with the birth rate of 7%.

结果：①178只注射pcDNA3.1-mutant LMNA后的存活受精卵移植至假孕鼠输卵管后，出生13只子代鼠，出生率只有7%；58只注射pcDNA31 -mutant LMNA后的存活受精卵移植到假孕鼠输卵管后，在移植后12~15 d的受体母鼠子宫内收集到1只活胚和5只死胚。

To isolate spermotogonia using two combinatorial enzyme three step wises digest the testicular tissues from 19 d-old-embryo after hatching,the cryopreserve effect of dimethylsulphoxide,glycerol and ethylene glycol cryoprotectants,each at(5%,10%,and 15%) concentration on the 19 d chicken embryonic SSCs was compared with fast freeze method.

采用二酶3步法获取孵化第19 d的鸡胚精原干细胞，比较在快速冷冻条件下3种冷冻保护剂(DMSO、乙二醇、甘油)在3个浓度5%、10%、15%条件下对鸡胚精原干细胞的冷冻保存效果进行研究。

Somatic embryogenesis usually suffers an dedifferentiation process in which some somatic cells are transitted to embryogenic cells from vegetative cells.

体细胞胚发生一般经历一个脱分化过程，即由营养生长的体细胞转变成生殖生长的胚性细胞。

The scientist has made a pointed comparison between suspensors of plant embryos and mammalian trophoblasts.

这位科学家把植物胚的胚柄与哺乳动物的滋养层做了直接的比较。

The histological observation showed that the larvae of S .japonicum in superinfected snails were sluggish in development, irregular, shrunken, deformed, relatively small in number as compared with the control. The sporocysts contained few germ balls or immature cercariae and most of the digestive glands of superinfected snails were atrophiej.

组织学观察发现各双重感染组钉螺消化腺萎缩，消化腺盲囊间隙只有少量血吸虫子胞蚴，血吸虫子胞蚴皱缩、变形及不规则，且子胞蚴中只含稀疏的尾蚴胚球，有的子胞蚴中已无胚球；而单独感染血吸虫的对照组中血吸虫均发育到成熟的子胞蚴或尾蚴。

The quality advantage: the Company is the only one from the extraction of corn germ to the press, refining the entire process to implement a comprehensive quality monitoring and management of enterprises, to ensure that the corn germ oil, natural, green and healthy.

品质优势：本公司是国内唯一一家从玉米胚芽的提取到压榨、精炼整个加工过程中实行全面的质量监控管理的企业，保证了玉米胚芽油的天然、绿色、健康。

Seeds usually 1, ovate-oblong; endosperm fleshy; radicle erect.

通常的种子1，卵状长圆形；胚乳肉质；胚根直立。

Among 33 genes in this study,25 were selected from a cotton somatic embryogenesis SSH array, considered differential expressed at different development stages such as the formation of embryogenic callus and somatic embryogenesis,the others including 5 SERK genes and 3 CKⅡgenes were acquired from the Genebank.

在所研究的33个基因中，有25个来自一个棉花的体细胞胚胎发生的SSH文库，这些基因在棉花胚性愈伤和各时期胚状体中有差异表达，另外5个SERK基因和3个CKⅡ基因来源于相关Genebank库。

Cell wall-related protein genes,adenine and amino acid metabolism-related genes and CKⅡgenes were behaved high expression level during the development and mature of somatic embryos.The high expression level of the post-translation modification genes,such as SERK gene,was considered as a sign that proteins interacted complexly.It was proved that the development and maturity of somatic embryos was complex as the start-up and morphogenesis of somatic embryos.

体细胞胚胎发育与成熟要求较高水平的细胞壁相关蛋白基因、腺嘌呤与氨基酸代谢相关基因与CKⅡ基因；以SERK为代表的翻译后修饰基因在体细胞胚发育阶段的高表达被认为是复杂的蛋白质相互作用的标志，证明了体细胞胚的发育和成熟与起始发生和形态建成一样是相当复杂的。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
