星形细胞

Traumatic injury with secondary hypoxia insult can significantly increase the degree of injury of cultured astrocyte in vitro.

创伤后低氧可显著增加体外培养星形细胞的损伤程度，此模型可用于体外研究创伤后低氧二次打击的机制。

But part of astrocytoma is very easy to relapse, which is related to its malignant level.

但部分星形细胞瘤容易复发，这与其恶性程度的高低有关系。

Objective To study the expressions of Survivin and VEGF in human astrocytoma and their significance.

目的 探讨凋亡抑制基因Survivin与血管内皮生长因子在人脑星形细胞瘤中的表达及意义。

Methods the clinical and pathological data of 54 cases of recurrent astrocytoma after the second operation were analyzed.

对54例复发性星形细胞瘤两次住院手术的临床和病理资料进行统计分析。

This is an astrocytoma, but I am not totally convinced of its grade or type.

这是一星形细胞瘤，但是不能完全肯定其分级和分型。

Methods: Totally 86 cases of astrocytoma tissue were studied accompanied with 8 cases of normal brain tissues.

收集经手术切除及病理证实的星形细胞瘤86例标本，8例正常脑组织作对照。

RM has special morphological characteristics; it should be differentiated from gemis tocytic astrocytoma, atypical teratoid/rhabdoid tumor, and malignant melanocytoma.

RM有特殊的组织学特点，应注意与胖细胞型星形细胞瘤、非典型畸胎样瘤/横纹肌样瘤、恶性黑色素瘤等鉴别。

Objective To study the MRI findings and the clinical features of the juvenile pilocytic astrocytoma of sellar region.

目的 分析发生在鞍区的青少年毛细胞星形细胞瘤的MRI特点及临床发病特点。

Results 5 cases central gaugliocytoma and 2 cases colloid cyst were located at middle line of ventricle,6 cases medulloblastoma were located at the top of the fourth ventricle or super cerebellum vermis,5 cases ependymoma were located at one lateral ventricle,3 cases ependymoma were located at the fouth ventricle,2 cases papilloma of choroid plexus werre located at triangle area of lateral ventricle,2 cases meningioma were located at triangle area of lateral ventricle,1 cases astrocytoma were located at lateral ventricle anterior horn.

结果 5例中央性神经细胞瘤和2例胶样囊肿发生于中线室间孔区；6例髓母细胞瘤分别发生于小脑上蚓部和四脑室顶部近中线区；5例室管膜瘤发生在单侧脑室，年龄分别为28～36岁；3例室管膜瘤发生在四脑室，年龄分别为7～13岁；2例脉络丛乳头状瘤发生侧脑室三角区，年龄13～15岁；2例脑膜瘤发生在侧脑室三角区，年龄为15～71岁，1例巨细胞型星形细胞瘤发生在右侧脑室底部，年龄为30岁。

Stellate cells are special in that high concentrations of them can only be found in the cerebral hemispheres.

星形细胞不是普通的细胞，它在大脑半球中含量十分丰富。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
