The allantoin is one kind of new high quality cosmetics raw material, may directly or takes the upscale cosmetics chemical additive indirectly, like uses in daily necessities' and so on lipstick, opaline, facial cream, toothpaste, shampoo, scented soap chemical additives, the increase allantoin cosmetics has the Protective tissue, the water affinity, to absorb water and to prevent functions and so on moisture content sending out.

尿囊素是一种新型优质的化妆品原料，可以直接或间接地作为高档化妆品添加剂，如用于唇膏、发乳、面霜、牙膏、香波、香皂等日用品的添加剂，添加尿囊素的化妆品具有保护组织、亲水、吸水和防止水分散发等作用。

Pox formation increased from 13.3%-20% to 33.3%-40% after passaging through 9 days old chicken embryo. Typical virus particles were observed under transmission electronic microscope in ultrathin sections of pathological tissues, allantochorion membrane of chicken embryos and affected cells.

用待检病料感染的BHK-21细胞培养物接种9日龄鸡胚绒毛尿囊膜，随着传代次数的增加，痘斑病变的出现率从13.3%~20%上升至33.3%~40%；用山羊痘病变皮肤、鸡胚绒毛尿囊膜和感染细胞进行超薄切片，在电子显微镜下可以观察到典型的山羊痘病毒粒子。

When large quantities of viruses are required for vaccine production or chemical studies, the allantoic sac is utilized.

如绒毛尿囊膜是常用的接种部位，用于1、病毒滴定2、病毒形态学研究3、病毒鉴定，几种病毒能在绒毛尿囊膜上产生水泡样损伤，称为痘痕。

In CAM assay, anti-Robo1 function-blocking mAb could inhibit capillary formation in the chicken allantoic membrane.

在鸡尿囊膜的血管形成实验中，Robo1的功能阻断性单克隆抗体抑制尿囊膜上毛细血管的形成。

In order to discuss the optimal condition in which GPMV proliferates in chicken embryo and its pathogenicity, GPMV of different titer was inoculated into 911-day chicken embryo and the allantoic fluid was harvested after 36, 48, 60, 72 and 84 h, the HA titer was measured as well.

为了探讨鹅副粘病毒在鸡胚中增殖的最佳条件及其致病性，将不同血凝滴度的鹅副粘病毒分别接种于9~11日龄鸡胚尿囊腔，收获孵化36、48、60、72和84 h的鸡胚尿囊液，测定血凝滴度。

The result showed that the HA titer of virus in allantoic fluid reached its maximum 1:256~1:512 in the condition that the 9-day chick embryo received 50 times dilution of 1:64 GPMV and cultured for 48~72 h in 37℃.

结果表明将血凝价为1：64的鹅副粘病毒稀释50倍后，接种9日龄鸡胚，37℃培养48~72 h获得的尿囊液血凝价可达1：256~1：512，平均尿囊液量可达9.4 mL/胚。

The split between the two groups can hardly be papered over.
