卵黄囊

And it is proved that inoculation via yolk sac is more effective than via allantoid cavity for the isolation of ARV.

结果成功分离到4株广西地方毒株；经对比发现，以卵黄囊接种的途径进行ARV的分离效果较好。

Cancer of ovarian and transparent cell is most constant tumour of as epithelial as the ovarian surface of confuse of interblend of tumour of cell of the former reproduction that send a gender sex, especially with yolk bursa tumour and asexuality cell tumour are differentiated harder.

梗概： 卵巢透明细胞癌是最常和原发性生殖细胞肿瘤相混淆的卵巢表面上皮性肿瘤，尤其和卵黄囊瘤和无性细胞瘤较难鉴别。

The results showed:(1) the cellule morphous and the disposition in chick embryo of PGCs were coincident no matter stained by PAS or HE staining, and HE staining could disclose the morphologic characteristics more clearly, exactly and completely;(2) genesis of blood island could be observed at the boundary of light and dark region of the extraembryonic blastoderm at about 26 hours;(3) both the blood vessel endothelium cells and free cells of the blood island were differentiated from PGCs. The generating of genuine yolk sac was at about 44-48 hours.

结果表明：①用经典的识别原生殖细胞的PAS染色方法与HE染色所观察到的PGC在鸡胚的分布及细胞形态基本一致，而HE染色较PAS法能更有助于清晰、完整、准确地识别PGC的细胞内部结构特征；②在孵化26小时的鸡胚胚外胚盘的明暗交界处可见血岛的发生，血岛发生的时间比真正的卵黄囊产生时间（大约44-48小时）要早很多；③血岛周围的血管内皮细胞与管腔中游离细胞都来自PGC。

It is concluded that the initial ancotomic site of blood island genesis may be is mesoblast of extraembryonic blastoderm rather than the yolk sac; the blood vessel endothelium cells and the blood cells are generated parallel; the PGCs are the common ancestry of angioblast and HSC.

血岛最早发生的解剖位置可能不是卵黄囊而是胚外胚盘中胚层，血管内皮细胞与血细胞平行发生，PGC是成血管－造血干细胞的共同祖先。

This study deals with the development of ovary in a Cichlid, Sarotherodon aurea.

Sarotherodon aurea卵巢的发育在卵黄囊消失时，初级生殖腺已形成。

GALTs were found in the small intestine,Meckel′s diverticulum,caecum and in the terminal rectum.

结果表明，GALT分布在小肠、卵黄囊憩室、盲肠和直肠末端。

Only 41 days and the embryo sac did not see, not the original heart tube is a normal pulse, the next time will be good.

才41天没有见到卵黄囊及胚芽，未见原始心管搏动是正常的，再过段时间一定会好的。

The neural embryo development and yolk sac larval morphological development of E. septemfasciatus was investigated.

本实验对七带石斑鱼胚体、卵黄囊期仔鱼形态发育的过程进行观察，研究其发育特征。

Tissue transcription analysis indicated that chIL-2Rγ mRNA was found in cerebrum,cerebellum,medulla spinalis,bursa of fabricius,thymus,spleen,bone marrow,cecal tonsil,stomachus glandularis,stomachus muscularis,jejunum,yolk sac diverticulum,ileum,cecum,rectum,heart,kidney,lung,liver,skeletal muscle and skin, but was not detected in duodenum and testis.

RT-PCR检测发现，鸡IL-2Rγ mRNA分布于大脑、小脑、脊髓、腔上囊、脾、胸腺、骨髓、盲肠扁桃体、腺胃、肌胃、空肠、卵黄囊憩室、回肠、盲肠、直肠、心脏、肾、肺、肝、骨骼肌和皮肤，而在十二指肠和睾丸中没有检测到其转录。

6MM, intra-uterine pregnancy 4 + weeks. BB development

我54天时照B超示见胎心博动，但有卵黄囊，见妊娠囊一个，最大径14.6MM，子宫内妊娠4+周。

In her eyes, because that is the doorway toher heart * the place where love resides.

女人的漂亮必須從她的眼睛中去看，因為那是她心靈的窗戶和愛居住的地方
