胚胎

Recent studies suggest (see single embryo transfer is inherently safer than implanting multiple embryos).

最近的研究提示（单个胚胎移植比多胚胎移植更安全）。

Sea perch embryos were cryopreservated in liquid nitrogen for 0.5~24h, 4 survival embryos were also obtained and one of them hatched, furthermore the fry without feeding survived for 3 days.

其中妒鱼胚胎成活4枚，孵化1枚，孵化后的妒鱼苗在没有投喂饵料的情况下存活了3天(在液氮中保存了28h)；牙醉胚胎成活5枚，孵化4枚，孵化后其中l尾牙虾苗在没有投喂饵料的情况下存活了6天(在液氮中保存了24h)。

In the course of vitrification of sea perch embryos at tail-bud, heart-beating and pre-hatching stage using VSD2, we got 4 survival embryos, one of which hatched.

利用VSD2冷冻花鲈胚胎，分别在尾芽期、心跳期和出膜前期获得4粒成活胚胎，其中1粒孵化出膜，成活率为2.17%-5.88%，成活时间为42-73h。

However, its activity is absent in all the tissues of gold fish examined.

比较和检测了金鱼单倍体胚胎与二倍体胚胎的MAPK的表达差异。

The quantity of CD3+ cells in the EdNSC, AdNSC of cloning goattransplantation group and control group had no statistics difference(P＞0.05) at acute and chronic period.Overall, in our study, We got the conclusions as follow: 1,The EdNSC, AdNSCof cloning goat and the AdNSC of the non-cloning goat were successful obtained;EdNSC growed faster than AdNSC in the same cell culture method. 2,The braincontusion and laceration model of cloning goats were successful established by freefalling of 50 gram of steel ball accelerate strike on the goat brain from 100cm height.3, EdNSC and AdNSC transplantation both had obvious therapeutic effect on braincontusion and laceration of cloning goats; The therapeutic effect of EdNSCtransplantation was better. 4, Allograft of stem cells has acute and chronicimmunological rejection and autografting of stem cells has no acute and chronicimmunological rejection.

在相同的条件下，EdNSC体外培养速度比成AdNSC快。2对羊脑上薛氏沟周围运动皮层区使用50g×100 cm力度作自由落体加速撞击，可产生观察指标明确且存活率高的羊脑挫裂伤模型，有望广泛用于神经干细胞移植及药物等治疗的实验研究。3胚胎神经干细胞及成体神经干细胞移植治疗脑挫裂伤后均有较明显的治疗效果；二者相比较而言胚胎神经干细胞稍好于成体神经干细胞。4中枢神经系统异体神经干细胞移植存在着明显的免疫排斥反应，而自体神经干细胞移植基本无免疫排斥反应

Using Ham's F12 hormonally defined medium, we are able to maintain the specific polygonal morphology and stable phenotype of primary HFHs for 1 week, and moreover, the cells retain a higher proliferative potential.

Ham's F12条件培养基体外能够显著促进人胚胎肝细胞增殖，维持胚胎肝细胞的特异性形态和表型的稳定。

Daily-growth increment of otolith and growth of Japanese parrotfish were studied and research objects were taken from Zhoushan Fishries Research Institute in April 2009. Microscopic observation was performed on the growth of the otolith during the embryonic development of artificially fertilized eggs and the formation of the first daily growth increment on otolith of larvae.

2009年4月15日－5月5日在浙江省舟山水产研究所条石鲷人工繁殖期间，逐日选择胚胎和仔鱼样本，连续解剖观察发育后期胚胎和前期仔鱼，光镜观察仔鱼矢耳石和微耳石的形态、日轮数，测定其直径，研究条石鲷的耳石日轮和生长。

In this experiment,mCZB medium added in penicillin and dihydrostreptomycin was used as control group, the effect of the Chinese medicines component Berberine and Baicalin on 2-cell embryos in vitro culture from the mice were compared respectively.

小檗， 胚胎，细胞，小鼠，效果摘要：试验以添加抗菌素的mCZB液为对照组，分别筛选比较了小檗碱、黄芩苷二种中药成分对小鼠2-细胞胚胎体外培养效果的影响。

Cryopreservation of fish gametes and embryos plays an important role in the preservation of seed resource, cryobiology, genetics breeding and aquaculture.

鱼类配子和胚胎的冷冻保存对鱼类种质资源保护、低温生物学、遗传育种和水产养殖业都具有重要的意义。胚胎的冷冻保存是一项系统工作，一个环节处理不慎，都会导致整个冷冻保存实验的失败。

本文以单胚水稻IR36作为对照，系统观察了多胚水稻品系APⅣ的胚胎发生过程，包括胚囊的形成、发育、受精及其胚胎发育；。。。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
