Consequence:Afer duplicating the model,many patho-representations occur in theaging rats including the worse general states,increasing active oxygen freeradical,lipid peroxidation and apoptosis,reducing antioxygen capability andionic transport capability in the cell envelope,overexpression of P16,impairing hippocamp nerve cell architecture and depositive lipofuscin inultramicro-morphology.

结果：D-半乳糖致亚急性衰老大鼠出现一般状态较差、活性氧自由基和脂质过氧化产物增加、抗氧化能力明显下降、细胞膜离子转运能力降低、P16过度表达、细胞凋亡增加、海马神经元细胞超微结构损伤以及神经元细胞内脂褐素沉积的病理表现。

Embryonal carcinoma and neuroblastoma are both formed during embryonal development, retinoic acid can induce them to differentiate into neurons.

胚胎瘤和神经母细胞瘤都是胚胎发育期间形成的肿瘤，维甲酸可以诱导这两种肿瘤细胞向神经元方向分化，在研究神经元分化机理时作为细胞模型得以广泛应用。

Pentylenetetrazol is a central nervous system drug that induce chronic and acute epilepsy model to study epileptogenous mechanism .Kindling is a natural epileptogenous phenomenon.

我们前期研究工作发现：应用电镜、Timm染色等从形态结构方面已证实在点燃前神经元发生了可塑性改变包括苔藓纤维芽生，新突触形成(突触密度增大或数量增多)与突触重排等，但这些只是一个初步探索，仍不能够说明问题的全部，如其分子生物学基础、神经元凋亡情况等尚不清楚，需进一步研究探讨。

These circumstances are believed to cause metabolic disturbances in neurons in the hippocampus, which may disappear and be subsequently replaced by gliosis.

MTS被认为与婴幼儿其的发热性惊厥和持续癫痫状态相关，这些事件被认为引起了海马区神经元代谢异常，这些神经元丢失并被神经胶质所取代。

NMDA receptor subunits express weakly at postnatal 7 days (P7),goes up at P14,reaches maximum level at P21,then remains this level until adult. Conclusion Neuronal functional NMDA receptors are composed of NMDA R1 and NMDAR2A in heteromeric configuration in the ventral horn of spinal cord;N MDA receptors may be involved in motor neuron maturation and plasticity during p ostnatal development.

NMDAR1和NMDAR2A是构成脊髓前角神经元功能性NMDA受体的重要亚基，NMDA受体可能参与生后早期运动神经元成熟或可塑性调控过程。

BACKGROUND: Recent studies have demonstrated that phenolic alkaloids from Menispermum dauricum can protect the heart and brain from ischemia/reperfusion injury, and promote neuron survival by inhibiting neuronal Bax and upregulating Bcl-2 expression following ische-mia/reperfusion.

背景：近来实验证明，蝙蝠葛酚性碱有保护心脑缺血再灌注损伤的作用，能通过抑制缺血再灌注后神经元bax和上调Bcl-2表达促进神经元存活。

Objective To study the effect of 9 kind of main Ginsenosides on cultured spinal moter and spinal ganglinic sensory neurons growth from embryonic rat.

摘 要 目的：探讨9种主要人参皂甙单体对体外培养鼠胚脊髓运动神经元和脊神经节感觉神经元生长的影响。

Fate-mapping analysis after olfactory neuroepithelium lesioning shows that HBCs are competent to regenerate both neuronal and non-neuronal olfactory neuroepithelium lineages.

嗅神经上皮损害后细胞命运映射分析显示HBCs足以重建嗅神经上皮的神经元谱系和非神经元谱系。

They include cerebellum,cerebral cortex,hypothalamus, mesencephalon, and pons.A few of positive cells could be seen in the medulla oblongata. NADPH-d positive neurons appears blue.Their shapes were diversform such as polygon,fusiform,nummular and oval etc. Karyon hasn't pigmentation. Dendriate and axon's pigmentation are clear.

实验一利用NADPH-d酶组织化学技术，对NOS阳性神经元在兔脑的总体分布规律及其衰老性变化进行了系统研究，结果表明：①NADPH-d阳性神经元分布于兔脑各个部位，几乎涉及所有区域：包括小脑、大脑皮质、丘脑下部、中脑、脑桥和小脑，而延髓分布较少。

⑴There are NOS/ER positive neurons in the hypothalamic paraventricular nucleus, supraoptic nucleus, periventricular nucleus and lateral hypothalamic area.⑵The double-labeled neurons were mostly distributed in the medial dorsal and lateral dorsal of supraoptic nucleus and in the medial parvicellular, ventral zone. They were extensive slightly,but scattered in lateral hypothalamic area, sporadic in the periventricular nucleus.

1在大鼠下丘脑视上核、室旁核、下丘脑外侧区及室周核均有NOS与ER双染神经元分布。2 NOS与ER双染神经元主要集中分布在视上核的背内侧和背外侧部及室旁核小细胞部腹内侧区，在下丘脑外侧区分布较广但比较分散，室周核呈散在分布。

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。
