胚细胞瘤

Benign cystic teratomas are well-differentiated tumors composed of a variety of parenchymal cell types representative of more than one germ layer, usually all three. The most common locations are the gonads and sacrococcygeus.

The morphological and anatomical characteristics of"Zha′ai 76"Comparing with the plants of normal M.baccata and ordinary hybrid,"Zha′ai76"and other plants with Dw major gene showed that:the length of springgrowth or main shoot is shorter by 59.6-66.2%;the ratio of length:diame-ter of new shoot smaller by 33.2-58.4%;the length of internee shorter by14.0-42.7%:the node number of spring growth lesser by 40.7%;the cauli-cle height under the cotyledons of hybrid seedlings shorter by 65.0%;the in-dex of leaf stalk(stipe length:stipe thiek ness)on the spring growth smaller by34.5-50.2%;the length of leaf stalk shorter by 25.2-45.7%;the boundarybelt between spring and autumn growth has knob-like nodes;the margin of leafappears wave-like;the sepals with spinous proeessuses are massive and small;the eonstriction at calyx is not obvious;the trace of abscisic sepals is big;the ca-lyx end of fruit is plan or convex;the shape of shoot tip(of"Zha′ai 76")iswider and shorter;and in 1.0mm part from the top of shoot tip,there are manyspecialized cells which are larger in volarae,but with lesser inner material andwith smaller or no nucleus.

"扎矮76"的形态解剖特征与普通山定子和杂交后代中普通型植株对比，"扎矮76"和其它携带Dw主基因植株的：春梢短59.6-66.2％，梢长与梢粗比值小33.2-58.4％，节间短14.0-42.7％，春梢节数少40.7％，杂种苗下胚轴短65.0％，春梢叶柄形指数小34.5-50.2％，叶柄短25.2-45.7％，春秋梢交界处有瘤状突起，叶缘波状，萼片肥厚有刺状突起，萼部缢痕不明显，脱萼后萼痕较大、萼洼平或高于果面；新梢生长点宽而短，在距顶端1.0gmm处有较多体积较大、内容物较少、细胞核小或无的待化细胞。

The purified immunoglobulins were effective in the inhibition of endothelial cell adhesion, proliferation and angiogenesis in chick chorioallantoic membrane in vitro, and in anti-tumor activity by the adoptive transfer in vivo.

将该抗体纯化后，纯化的免疫球蛋白可以有效地抑制体外内皮细胞的粘附、增殖和鸡胚绒毛尿囊膜的新生血管形成，体内过继输入治疗亦可引起抗瘤效果。

Results Histologically, AT/RT was characterized by the presence of rhabdoid cells associated with various degrees of primitive neuroectodermal, epithelial or mesenchymal differentiation.

结果 非典型畸胎样／横纹肌样瘤具有特征性的横纹肌样细胞，伴有不同程度的原始神经外胚叶、上皮和间质分化。

For tumors which have been well sampled and exhibit (1) a microcystic pattern and regions with lobulated cellular masses with intervening, sometimes hyalinized fibrous stroma,(2) an absence of morphologic features enabling any other specific diagnosis in the sex cord-stromal category,(3) an absence of epithelial elements, and (4) an absence of teratomatous or other germ cell elements, we propose the designation microcystic stromal tumor.

我们很好地抽样调查了4例肿瘤，显示：（1）微囊样式和有时插入玻璃样变的纤维间质中的分叶状细胞团区，（2）能造成在性索间质这个大类中其他具体诊断的形态特征缺失，（3）上皮成分缺失，（4）畸胎或其他胚芽细胞成分缺失，我们提议定其名为微囊性间质瘤。

Recombinant endostatin is a specific inhibitor of chick chorioallantoic membrane angiogenesis and human vitelline vein endothelial cell ECV-304 proliferation. The recombinant endostatin regressed established syngeneic B16 melanoma tumor in mice.

重组内皮抑素能够抑制鸡胚尿囊膜血管生成和人脐静脉内皮细胞ECV-304的增殖，在小鼠体内实验中对黑色素瘤产生良好的抑瘤效果（P＜0.01）。

The neurofibromas are multiple benign neoplasms of the peripheral nervous system , arising from mesodermally-derived Schwann cells

神经纤维瘤是外围神经系统的多发良性肿瘤，由中胚叶的雪氏细胞发生。

No teratomas were formed after injected human EG cells into the nude mice one month later.

裸鼠体内移植人胚EG细胞未形成畸胎瘤。6。

There were all kinds of tissue cells in the teratomas acquired from in-vitro differentiation, such as, neuro epithelium, skeletal muscle, respiratory epithelium. This further proved the isolated mouse ES cells could differentiate into three germ layers of tissue types.

体内分化实验所获得的畸胎瘤中存在各种组织细胞，如一些神经上皮样组织；横纹肌；呼吸上皮样组织等，这进一步证明所分离获得的小鼠ES细胞具有三个胚层的分化能力。

Methods The chemical hypoxia was induced by incubation of U251 cells with cobalt chloride.

以氯化钴模拟缺氧，采用RT-PCR、免疫细胞化学方法分别检测缺氧诱导因子-1α和血管内皮生长因子mRNA和蛋白的表达，鸡胚绒毛尿囊膜模型检测缺氧时胶质瘤细胞血管生成情况。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
