The results showed that DNA vaccine pcDNA3.1-3-1E could remarkably increase the number of CD8+ T lymphocyte after two immunizations,and also could provide partial immune protection against homologous Eimeria challenge,such as significantly decreasing oocyst shedding,reducing the average lesion score in duodenum,improving body weight gain and so on.

结果显示，与载体对照组相比，质粒pcDNA3.1-3-1E 2次免疫后可显著提高脾CD8+ T淋巴细胞亚型数量，并具有一定的抗球虫免疫保护作用，可显著减少每克粪便的卵囊排出量，降低十二指肠病变记分，减少增重下降等。

There were also a number of protoplasm body appeared in the perivitelline, especially in the area near the first polar body.

在卵周隙尤其是在第一极体的旁边，有许多原生质球存在。

Goose ; coccidian species ; experimental infection ; pure oocysts

鹅； 球虫种类；人工感染；纯种卵囊

In this plan 84.8% Sparus macrocephalus embryos are able to keep forms comparative normal, however, revival has not been found so far.

三者配合虽然没有得到复活胚胎，但能得到84.8%胚体、卵膜、卵黄囊和油球等形态都基本正常的胚胎。

The CDA gene shares high sequence similarity with that of fungi including Rhizopus oryzae (75%), CDA1(58%) and CDA2(56%) of Rhizopus circinans, Mucor rouxii(56%), Gongreonella bulteri(48%), Rhizopus stolonifer(39%), Phycomyces blakesleeanus(39%), CDA1(17%) and CDA2(16%) of Saccharomyces cerevisiae.

总状毛霉CDA基因与其它相近种米根霉、卷柄根霉的CDA1和CDA2、鲁氏毛霉、卵形孢球托霉、匍枝根霉、布拉克须霉、酿酒酵母的CDA1和CDA2的基因序列同源性分别为：75%、58%、56%、56%、48%、39%、39%、17%和16%；相应的氨基酸序列的同源性分别为：69.0%、57%、59%、55%、47%、30%、32%、18%、21%。

Vitelline antibody has significant dissolving and weakening effect on sparozoite, but it has no effect on the speed of sporation of E. tenella, and pathogenicity of sporulated oocysts.

tenella的子孢子具有明显的溶解和致弱作用，但对卵囊的孢子化速率和孢子化球虫卵囊的致病性没有明显影响。

Experiment Ⅴ: Mouse polyploid embryos were produced by electrofusing 2-cell blastomeres successionally.

实验六、通过2-细胞卵裂球交换制作2n／4n嵌合小鼠胚胎，对这种胚胎的发育能力进行了评价。

The reprogarmming of embryonic genome is likely the molecular foundation of the transition of highly differentiated oocytes into totipotential embryonic blastomeres.

基因表达的&再程序化&可能是高度分化的卵母细胞转变成胚胎中具发育全能性分裂球的分子基础。

Chicken (n=50) were randomly grouped in control, control, Bt crystal proteins- treated, Diclazuril-treated, and Amprolium-treated group. GroupⅡ,Ⅲ,Ⅳ, andⅤwere inoculated with 10×104 sporulated E. tenella PT0705 occysts per bird. The results showed that the anticoccidia indexes of the Bt crystal proteins,Diclazuril and Amprolium were 202.3,184.1 and 128.2 respectively.

将50只雏鸡随机均分为5组，Ⅰ组为无感染不用药空白对照组，Ⅱ-Ⅳ组各鸡均感染，每只鸡人工感染柔嫩艾美耳球虫PT0705卵囊10×104个，Ⅱ组为不用药对照组，Ⅲ组为苏云金杆菌晶体蛋白组，Ⅳ组为地克珠利组，Ⅴ组为氨丙啉组，观察效果。

In order to solve the existing problems of drilling gravel and cobble stratum,common tungsten carbide-insert drill bits, composite diamond-tungsten carbide button bits and impregnated diamond-tungsten carbide bar bits were designed and tested successively.

针对卵砾石地层的钻进实践，先后设计与试验了三种类型的钻头；普通八角合金钻头、金刚石-硬质合金复合球齿钻头与孕镶金刚石-针状合金复合式钻头。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
