It showed that in conditions of water temperature 20～21℃,salinity 20～30,pH 8.0～8.3,the fertilized eggs developed to 2-cell in about 2h,blastula stage in about 15h,gastrula stage 30h and the hatched out larva 152h after fertilization.

其结果表明：在水温20-21℃、盐度20-30、pH值8.0-8.3的条件下，受精卵受精后2h为2细胞期、15h为囊胚期、30h为原肠期、55h为胚体期、152h孵出仔鱼

The expression of subunits α5,β1,β3 was detected in normal morulas and increased in blastocysts. The expression of subunit α1 was not detected in morulas or blastocysts, but detected only in outgrowing trophocytes. 3. Expression of integrin β3 in irradiated group embryos was weaker than that of normal group. There was no expression of integrin α1 both in morulas and blastocysts in irradiated group and no difference in the expression of subunits α5 and β1 between these two groups.

结果：1、超声波照射组胚胎贴附率、滋养细胞外延生长率均显著低于正常胚胎。2、正常胚胎桑椹胚期即有α5、β1、β3整合素表达，而无α1表达；囊胚期α5、β1、β3表达增强，仍无α1表达；α1只出现在外延生长的滋养细胞。3、超声波照射组胚胎β3整合素的表达明显弱于正常组，且未见α1表达；而α5、β1的表达两组间无差异。

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。

Confocal microscope detection experiments showed that, in morulae and blastocysts, with theincreasing concentration of BPA, embryo of cytochrome C release rate increased. This showedthat the cytochrome C involved in BPA-induced the embryos apoptosis process. This processis regulated by the mitochondrial pathway.

激光共聚焦显微镜检测细胞色素C结果显示：在桑椹胚期和囊胚期，随着BPA处理浓度的升高，释放细胞色素C的胚胎比率逐渐增加，说明细胞色素C参与了BPA诱导胚胎细胞凋亡的过程，这一过程是通过线粒体通路来调节的。

The study was conducted at 25℃ to cryopreserve the Australia Boer goat blastocysts and compacted morulae by one or two-step straw (Experiment 1) and OPS methods (Experiment 2) with vitrification solutions (EFS30, ESF40, EDFS30 and EDFS40) or by slow freezing (Experiment 3) with cryopretectant (1.5 mol/L EG).

在25℃室温下，采用细管法和OPS法，以不同浓度的EFS、EDFS为玻璃化冷冻液，对澳洲波尔山羊致密桑椹胚和囊胚进行玻璃化冷冻保存。同时利用1.5mol/L EG为抗冻保护剂对胚胎进行常规法冷冻保存。

The results show the Boer goat oocyte and pre-implantation embryo are telomerase positive. According to the densitometry of bands under the CCD imagine system, the total telomere repeats product generated of oocytes, 4-cell, 8-cell, morulae and blastocyst are 25.348, 273.832, 56.117, 251.118, 519.46, respectively.

结果表明波尔山羊卵母细胞和早期胚胎都是端粒酶阳性；依据电泳条带在凝胶成像系统下的光密度计算相对总产品产量定量比较发现，卵母细胞最低为25.348，4-细胞为273.832，至8-细胞又降低到56.117，随后快速升高，桑椹胚为251.111，囊胚端粒酶活性最高为519.46。

Blastocyst rate of embryos co-cultured with pig oviduct epithelium cells came from pig oviduct during diestrus was significantly lower than metestrous. 4. The blastocyst rate of transgenic embryos collected at 24~26 hours and 18~22 hours after hCG-treated reached 45% and 20% respectively.

实验证明在hCG注射后24~26h之间获得的受精卵，在原核显微注射人血清白蛋白基因后体外培养，有45%注射胚发育到囊胚阶段，而在18~22h仅有20%，二者差异显著（P.05）。5。

Twenty hybrid embryos were harvested, which had fifteen blastocysts and five morulas.

收集到20枚杂交胚胎，其中囊胚15枚，桑椹胚5枚。
