It was used for detection of virus RNA in AIV infected chicken embryo allantoic fluids clinical specimens from various avian.

建立并优化了检测禽流感病毒核酸的探针杂交法，探针杂交法能鉴别出非免疫鸡胚和SPF鸡胚尿囊液中的病毒，攻毒后第 3天的 SPF和非免疫鸡泄殖腔拭子中 AIV的最大检出率为 1/10 ，对临床样品中的 AIV的最大检出率为 1/7，而直接 HA和 HI法及 AGP试验检不出临床样品的 AIV。

The amniotic fluid and allantoic fluid of chicken embryo have been analyzed and the resonances of most substances in them were assigned by 1-dimention and 2-dimention Nuclear Magnetic Resonance methods. This work could be the basis of quantitative analysis of metabolites and studying the metabolites changing between the amniotic and allantoic fluid during the hatching process. Also, it provided a new way to study the process of embryo developing.

用一维及二维液体高分辨核磁共振(Nuclear Magnetic Resonance，NMR)方法综合分析了鸡胚羊水和尿囊液的成分，对其中的大多数谱峰进行了归属，发现了一些未经报道的小分子代谢物，为研究胚胎发育过程中各个胚囊中体液的交换和小分子的代谢以及进一步对发育过程中代谢物含量变化的定量研究打下了基础，并为研究胚胎发育的过程提供了新的思路。

Virus was also cultured in allantoic cavity of chicken embryo with statistically significant HA titer at 1:6.8 as compared with virus control group (P.01) incubated 24 hours after injected with MEK first then injected with IBV.

在鸡胚尿囊腔中，先注入MEK孵育24 h后，再注入B型流感病毒的鸡胚也培养出病毒，HA滴度为1：6.8，与病毒对照组比较P.01，有统计学意义。

The quantities of starch grains in the two"cells"in micropyle part of embryosac gradually decrease and become unclear.With the further development of embryosac the starch grains in the central cell and antipodal cell disappear in succession,however,the egg cell does not.

在准极核移向胚囊中部前后，不同的功能性细胞有不同的表现，珠孔端的两个&细胞&淀粉粒数量逐渐减少并变得不明显，随着胚囊的进一步发育，其中中央细胞和反足细胞内的淀粉粒相继消失，但卵细胞内却一直保存着。

However, they could be grown on the chorioallantoic membrane of developing chick embryos, although only up to about 18 days incubation.

可是，肿瘤碎片却能在鸡胚绒毛尿囊膜（ chorioallantoic membrane， CAM ）上生长，尽管只能在孵育约18天以下的鸡胚中生长。

The optimum work concentration of the indirect ELISA for detecting and screening positive hybridoma cells was established by research again and again. Polystyrene microtitration plates were coated with the purified DHV antigen at the amount of 0.5μg/well.

对鸡胚和鸭胚增殖的尿囊液病毒用反复冻融、氯仿处理、0.22μm滤膜过滤、PEG反透析浓缩以及Sephadex G-200分子筛层析的方法进行纯化，并以此来包被酶标板以及进行BALB/c小鼠免疫，效果良好。

The researchs on isozymes indicated that some varieties of isozyme loci present during the embryo development. There are 7 esterase loci and 5 acid phosphatase loci during the periods between nucellar filament and early globular embryo; both of Est and Acp appeared the most diversity in the stage of 8-nucleate embryo sac.

用聚丙烯酰胺凝胶电泳的方法研究鹤顶兰从指状突起出现到早期球形胚形成的全过程中酯酶、酸性磷酸酶的变化发现：这一过程中酯酶表达有7个同工酶位点，酸性磷酸酶有5个同工酶位点，两者均在八核胚囊时期变化最显著。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
