After treating with 1% pancreatin,lecithinase C and 10% aether,the allantoic fluid of this virus could agglutinate the erythrocytes of chicken,sheep,human being,mouse and rabbit,while the allantoic fluid of this virus without this treatment had no this agglutinative activity.

经浓度1%胰酶、卵磷脂酶C和10%乙醚处理后，该病毒尿囊液可以凝集鸡、绵羊、人、小鼠和兔的红细胞，而未处理的病毒尿囊液则无此凝集活性。

The blastula formation whose embryos were from different sources was compared and the blastomere number, quality classification and the relationship between the parity of the blastomere number and the blastula formation at d 3 were studied.

比较不同来源胚胎囊胚形成情况和d3胚胎的卵裂球数、质量分级等；并利用废弃胚胎囊胚形成情况对体外受精妊娠结局进行预测。

GV oocytes with normal shape were not obtained in the group which was stored at 20℃ for 24 h and at 25℃ for 14 h; A blastula rates (64%) of all groups in average was gotten in culturing 2-cell in vitro, and there is no significant difference in temperature and time of storage. After transplantating some of the 2-cell embryos which were obtained from GV oocytes stored at 15'C for 8 h, normal infant mice could be obtained.

在20℃下保存24h和25℃下保存14h时，难以获得形态正常的GV期卵；体外受精获得的2细胞期胚经体外培养，总体上有64%的胚胎发育至扩张囊胚，未见有保存温度和保存时间的显著影响，且利用在15℃保存8h后的GV卵获得2细胞期胚的移植获得正常新生小鼠。

Methods: Human mature oocytes were cryopreserved using cryoleaf. Resuscitated oocytes were administered by intracytoplasmic sperm injection, embryo transplantation or cultured to blastulation, observing the fertilization and developmental capacity of oocytes.

运用cryoleaf进行人类成熟卵母细胞玻璃化冷冻保存，复苏后行胞浆内单精子注射-胚胎移植或培养至囊胚形成，观察复苏后卵母细胞受精及发育能力。

It is concluded that (1) there are no relationships between fusion rate and relativeness of the recipient cytoplasm to nucleus donor cells,(2) cytoplast of the goat MII oocyte can support the preimplantation development of SCNT embryos reconstructed with nucleus from other species,(3) the blastocyst rate of close relative inter-species SCNT embryos is higher than that of distant relative inter-species SCNT embryos.

由此结果得出以下结论：(1)山羊M II期卵母细胞胞质与供核细胞之间的亲缘性不影响两者的融合率；(2)山羊M II期卵母细胞的胞质能支持异种间体细胞核移植胚的着床前发育；(3)亲缘关系近的种间核移植胚的囊胚发育率高于亲缘关系远的种间核移植胚的。

Antheridia occurred in the cushion on the dorsal and ventral surfaces of gametophytes while archegonia were observed on the ventral surface only. On hermaphroditic gametophytes, antheridia and archegonia were usually intermingled. Both types of gametangia were eusporangiate.

藏精器与藏卵器分别在孢子洒播10及12月后发生；藏精器长在中肋的背面及腹面，藏卵器只在腹面发生；两性配子体的藏精器与藏卵器混生一起，两者均属厚囊蕨型。

Then we compared cleavage rate and blastocyst rate among different groups. After that we evaluated the quality of blastocysts by using ICM/TE (Inner cell mass/Trophectoderm cells) ratio via staining with propidium iodide and Hoechest333258, and analyzed the level of genome methylation and histone acetylation by immunofluorescence.

比较各组受精卵的卵裂率和囊胚发育率；并应用碘化丙啶和Hoechest333258对囊胚进行染色，利用ICM/TE值评价各组胚胎体外发育的质量；同时将囊胚进行免疫荧光染色，观察其基因组甲基化和组蛋白乙酰化的水平。

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。

There was no typical Golgi complex in oogonia, but there were some Golgi vesicles. At the early stage of vitellogenesis, Golgi complex was abundant whose saccules increased to more than ten layers. At the middle stage of vitellogenesis, Golgi complex grew more in numbers and got together, so its secreting quickened. Moreover, it formed a number of Golgi vesicles, which were filled with granule substances that changed into yolk granule finally.

卵原细胞内无典型的高尔基复合体，但具高尔基囊泡；卵黄发生早期，高尔基复合体发达，膜囊数达10多层；卵黄发生中期，高尔基复合体分泌活动加快，产生大量的大小囊泡，囊泡内充满颗粒状物质，最后演变成卵黄颗粒。

Methods: 86 cases of patients with pcos undergoing ovarian stimulation were randomly divided into letrozole group (40 cases) and clomiphene critate group (46 cases).

目的：比较两种促排卵方案用于多囊卵巢综合征不孕患者的促排卵及妊娠结局，旨在寻找一种新的促排卵药物。
