主要观察指标：谷氨酸和γ氨基丁酸及纳洛酮对急性分离的FCX锥体细胞兴奋性的影响。

A systematic method has been established for primary cultivating of cortical neurons. Observations indicated that the cortical neurons were affixed to the culture after 4h, and the nerve cells had 1-2 small processes. The Nissl's staining results show that the purity(≥92%) of the cortical neurons rose apparently on days 3 and 6 post-beginning of culturing with Ara-C inhibition. The MTT experiment show that the viability of the neurons was the highest,and they are oval,araneiform and pyramidal and formed an integrated neural network on day 6 post-beginning of culturing.

光学显微镜观察结果表明，培养至第4h绝大多数神经元已贴壁生长，胞体上可见1~2个细小突起；培养至第3d、第6d时，Nissl's 染色结果显示，加Ara-C能显著提高神经元纯度（≥92%）；MTT结合形态学观察结果表明，神经元培养至第6d时活性最强，细胞呈卵圆形、蜘蛛状、锥体状等多种形态，细胞胞体饱满，光晕明显，神经网络形成完整。

Base-catalysed hydrolysis is a typical course involving deprotonation leaving of Cl- and formation of the trigonal bipyramidal intermediate; edge displacement and ligand folding courses involve leaving of Cl- and formation of the square pyramidal intermediates.

典型的途径有经式异构体的碱催化水解，过程通过脱氢、脱氯以及三角双锥中间过渡态或中间体的形成来完成；另一途径为边沿取代及配体翻转历程，过程通过脱氯及四角锥的形成来完成。

Pyramidal eminence and chordal eminence should not be lowly abraded in order to avoid damaging the musculus stapedius and chorda tympani nerve when dealing with a facial recess lesion.

术中处理面神经隐窝病变时勿随意磨低锥隆起及鼓索隆起，以免损伤面神经镫骨肌支及鼓索神经。

ResultsDistances between pyramidal eminence and chordal eminence and the facial canal were 3.22±0.41mm and 3.59±0.48mm, and length of the tympanic chorda posterior tubules was 9.44±1.65mm. Distances between pyramid segment of the facial canal and chordal eminence, lateral semicircular canal and posterior semicircular canal were 3.34mm±0.42mm, 1.54±0.25mm and 2.15±0.29mm, respectively.

结果颞骨标本解剖观察结果，锥隆起至鼓索隆起的距离（3.22±0.41）mm、锥隆起至面神经管直线距离（3.59±0.48）mm、鼓索后小管的长度（9.44±1.65）mm；面神经管锥曲至鼓索隆起间的距离（3.34±0.42）mm、面神经锥曲至水平半规管距离（1.54±0.25）mm、面神经锥曲至后半规管距离（2.15±0.29）mm。

Results: Through the facial recess approach, the pyramidal eminence .canal of facial nerve, incudostapedial joint, base of stapes, cochleariform process .round window niche and promontorium tympani were all visible from different directions.

结果：经面神经隐窝入路从不同的角度可清楚地看到锥隆起、面神经管凸、砧镫关节、镫骨底板、匙突、圆窗龛及鼓岬等主要结构。

Using the intracellular recording technique for monitoring the excitatory postsynaptic potentials of CA1 pyramidal neuron and delivering an activator of protein kinase C and/or inhibitors of PKC and 〓/calmodulin-dependent protein kinase Ⅱ into postsynaptic cell in hippocampal slices, we studied the role of postsynaptic PKC and CaMKⅡ in long-term potentiation induced by high frequency stimulation at the CA1 synapses made by Schaffer collateral/commissural and perforant pathway afferents.

用电生理学方法在大鼠海马脑片CA1区锥体细胞记录Schaffer侧枝和穿通通路到CA1神经元突触的兴奋性突触后电位，通过送蛋白激酶抑制剂和激活剂进入突触后细胞，我们研究了突触后蛋白激酶C和依赖钙/钙调蛋白的Ⅱ型蛋白激酶在高频刺激诱导的长时程增强产生和维持中的作用。

Proximal dendrites of hippocampal CAI pyramidal neurons receive mainly the inputs from schaffer collateral/associational commissural pathways, whereas the distal dendrites receive mainly the inputs from entorhinal cortex through TA pathways.

由于近端树突接受海马内部侧枝／联合纤维投射的信息，远端树突通过TA通路接受内嗅皮层投射的信息，由此提示，CA1区锥体细胞对来自海马内部和直接来自皮层的信息输入采用了不同的整合方式。

The positive cells are distributed in layers,the long dendrites of the pyramidal cells are apparent.

Results All affected individuals manifested with age-dependent seizures, combined with tremor, dyssynergia cerebellaris myoclonica and pyramidal sign.

结果 T家系患者临床表现为多种形式的癫痫发作、震颤、肌阵挛小脑协调障碍和锥体束征。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.

阿基坦法国西南部一个历史地区，位于比利牛斯山和加隆河之间，在1137年阿基坦的埃莉诺与国王路易斯七世结婚之后阿基坦公国加入法国，但当她再嫁英国亨利二世后，其归属权便受到争议

There are moments when I look at the smiling , happy faces of my expectant staff and wonder how they will cope when confronted by an outraged housemaster along with an unrepentant and recalcitrant bleached blond teenager in 18 years ' time .

有时候，我看着那些满怀期待的员工微笑，幸福的脸，想着当他们遇到一位愤怒的宿舍管理员和一位不知悔改，叛逆，而且将头发染成白色的18岁少年时，他们会如何处理。
