In the experiment, the FSH+LH combinations were adopted to superovulate KM mice to ascertain the proper phase to gain morulae and blastocysts, three ways were adopted to split the morulae and blastocysts, demi-embryos were cultured in D-PBS, mTCM199, CZB, mM16 added with FCS or MS of different concentration, and transplantation of the blastocysts derived from demi-embryos was performed.

本试验以昆明白小鼠为实验动物，试采用FSH和LH进行超排处理，确定了该处理程序下获取桑椹胚、囊胚的恰当时间，比较了三种方法对桑椹胚和囊胚分割的效果，采用了添加不同浓度FCS、MS的4种培养基对分割胚进行体外培养，并进行了半胚移植。

Air is clean spend and fall next bacterium are current air of product of province IVC system, isolator purifies Jiangsu to roughly two kinds of air current organize means, one kind sends a top to answer for the top: IVC remands wind filters through containing directly top of basket case case, horniness isolator remands on ben top wind; remands another kind to be the same as one side parallel: IVC remands wind contains filter film with a side face in basket box undertake inside aperture, soft qualitative isolator is sent by ben a side wind is answered on wind, means of two kinds of air current all is be not one-way and popular form.

目前实验动物相关国家标准对此类设备各项技术指标的检测并无说明，笔者对该类产品按江苏省地方标准[1]检测进行了初步的探索。1空气洁净度和落下菌目前江苏省IVC系统、隔离器产品空气净化大致有两种气流组织方式，一种为顶送顶回：IVC送回风直接通过含有过滤膜的笼箱盒盖，硬质隔离器在内室顶上送回风；另一种为同一面平行送回：IVC送回风在笼箱同一侧面含有滤膜孔内进行，软质隔离器由内室一侧送风对面回风，两种气流方式均为非单向流行式。

本研究的目的是建立一种快速准确的检测灵长目类动物生殖腺和血液中DNA疫苗残留拷贝的方法，为疫苗进入一期临床实验和进行安全性评价奠定良好基础。

Therefore, researches on breeding, genetics, nutrition and husbandry, dairy technology, management and biotechnology of economically valuable animals, and of laboratory species relevant to agriculture, are available through this site.

因此，对从事育种，遗传学，营养和农业，奶制品生产技术，经济价值动物和与农业有关的实验品种的管理和相关生物技术等方面研究的人员很有利用价值。

In this paper, serum thyroid hormones level of the adult rats exposed to decabrominated diphenyl ether（BDE-209） at different doses was determined and the influence of BDE-209 to thyroid hormones was studied preliminarily. The dose dependent relationships between THs and BDE-209 concentrations were studied.

论文建立了十溴联苯醚（BDE-209）暴露剂量的成年大鼠模型，测定了不同暴露剂量的实验动物血清甲状腺激素（Thyroid hormones，THs）水平，初步研究了PBDEs污染物对生物体甲状腺激素的影响。

Nevertheless, they can combine with amines or amides in food to form N-nitrosocompounds, nitrosamines and some of these have been shown to be carcinogenic in experimental animals and epidemiologically implicated carcinogenicity.

不过，硝酸盐及亚硝酸盐可以与食物所含的胺或胺化物化合，形成硝基化合物-硝胺。在动物身上进行的实验结果显示，部份硝胺是会致癌，而流行病学的研究结果也显示有些硝胺与癌症有关。

These results suggest that splenic contraction occurs in humans as part of the diving response and splenic emptying may prolong repeated apneas.

这实验清楚的验证脾脏在哺乳类动物潜水反射中扮演重要的角色而且经过多次的闭气后就会引起脾脏收缩。
