卵球

The surface of the egg opposite to the animal pole .

与卵黄偏度大体相对应，植物极区的卵裂球大形的场合较多。

The mitotic error rate in cleavage stage embryos was proven to be higher than the meiotic aneuploidy rate and as a consequence, the genome of a single blastomere is not representative for the genome of the other cells of the embryo.

在卵裂期胚胎这种有丝分裂的错误率被证明是高于减数分裂的非整倍体错误率，因此，单个卵裂球的基因不能代表其他胚胎细胞的基因组。

Ovine immatured oocytes, matured oocytes and embryos from 2-cell stage to blastocyst produced in vitro were recovered, and RT-PCR was used to semi-quantify mRNA expression. Proteins of Cx43 and Cx45 were detected by using a combination of immunocytochemistry and Laser Scanning Confocal Microscope.

收集绵羊未成熟和成熟卵母细胞以及体外受精早期胚胎各发育阶段的卵裂球细胞，通过RT-PCR半定量检测Cx43和Cx45基因的mRNA表达量；通过免疫组织化学方法结合激光扫描共聚焦显微镜检测Cx43和Cx45蛋白在绵羊体外受精的早期胚胎发育过程中的表达情况及表达区域。

Tenella YL attenuated strain were used to infect chickens perorally, then the abundant sporulated oocysts were collected by saturated saline floating measure. The size of the attenuated oocysts was about 19.8~21.2×15.5~16.6μm and the conformation of the strains were integral. 4 The prepatent period of E.

tenella YL减毒株孢子化卵囊经口服感染鸡，用饱和食盐水漂浮法能够收集得到球虫孢子化卵囊，杂质少，形态完整，减毒株卵囊的大小为19.8~21.2×15.5~16.6μm。

Sagittarius, each female constructs a tunnel after she has mated and then packs it with the stuff in the form of a brooding ball, on which she lays her eggs. Her mate guards the entrance, fighting other males to stop them entering the tunnel and cuckolding him.

举箭嗡蜣螂为例，每只雌性蜣螂在交配后就会建洞穴，在球状物上产卵，然后把带卵的球状物塞满整个洞穴，其伴侣则守护洞穴出入口，对抗其它雄性蜣螂阻止他们入侵，也避免自己被戴绿帽。

举箭嗡蜣螂为例，每只雌性蜣螂在交配后就会建洞穴，在球状物上产卵，然后把带卵的球状物打包回府，其伴侣则守护洞穴出入口，对抗其它雄性蜣螂阻止他们入侵，也避免自己被戴绿帽。

Indirect immunofluorescence was used to observe the distribution of fibronectin in human oocyte and 2-cell to morulae embryos.

纤维粘连蛋白均匀分布在体外未受精人卵母细胞和受精后人胚胎早期发育的不同阶段的卵裂球表面，各时期的免疫荧光强度未见明显差别。透明带未见纤维粘连蛋白表达。

The plasmid pcDNA3.1-3-1E and pcDNA3.1 was respectively used to immunize SPF chicks by injection intra-muscularly in thigh muscle at 14 and 21 days of age.Chicks in each group except that in the unchallenged control group were challenged with 5×104 E.acervulina sporulated oocysts at 28 days post-inoculation,and the immune protective efficacy was observed.

将构建的重组质粒以及空载体质粒分别于14、21日龄分2次经腿部肌肉注射免疫SPF雏鸡，28日龄除非免疫非感染对照组外各组攻击性感染5×104个堆形艾美球虫孢子化卵囊，观察真核表达质粒对球虫感染鸡的免疫保护作用并探讨其免疫保护机理。

To analyze effect of diclazuril and maduramycin on 18S rDNA of Eimeria tenella, the 18S rDNA of sporulated oocyst of the E. tenella anti-diclazuril strain, the E. tenellaanti-maduramycin strain and the E. tenella drug-sensitive strain were cloned and sequenced, and were compared by using DNAStar 5.0 and RNADraw 1.1, respectively.

为探讨抗球虫药物地克珠利和马杜拉霉素对柔嫩艾美球虫18S rDNA的影响，分别对人工诱导的柔嫩艾美球虫地克珠利抗药株、马杜拉霉素抗药株和药物敏感株孢子化卵囊的18S rDNA基因进行了克隆测序，并通过生物信息软件进行对比差异分析。

Ten 10-day-old artificially-reared coccidian-free goslings were inoculated orally with 2.0×105-6.5×105 of sporulated oocysts of Eimeria stigmosa,respectively, and killed at intervals from 48th h to 180th h post-inoculation.

给10只10日龄雏鹅分别经口接种2.0×105~6.5×105个多斑艾美球虫孢子化卵囊，在接种后48~180h分期剖杀，对多斑艾美球虫的生活史和致病性进行了动态观察。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
