兴奋性的

The primary noxious afferent neurotransmitters excitatory glutamate and substance P play a pivotal role in the development and maintenance of chronic inflammatory pain.

初级伤害性传入神经元的兴奋性递质谷氨酸和P物质对慢性炎性痛的形成和维持起到非常关键的作用。

Background: The neuron death resulting from traumatic brain injury can be classified into 3 types:(1)neuron death due to primary injury;(2)neuron necrosis due to secondary injury such as hemorrhage, compression, anoxemia and ischemia;(3)neuron apoptosis due to inflammatory factor, cytokine,, excitatory transmitter, Ca~(2+) overload and oxygen radical et al.

引言创伤性脑损伤所致的神经元死亡主要有三种：①原发性损伤所致的神经元直接死亡；②外伤后出血、压迫、缺血缺氧等继发性损伤因素所引起的神经元坏死；③炎性介质、细胞因子、兴奋性递质、Ca~(2+)超载、氧自由基等因素所诱发的神经元凋亡。

It can result in accurate and optimal balancing between the excitatory and inhibitory control functions of the cerebral cortex.

它可以产生准确的和最优平衡之间的兴奋性和抑制性控制的职能，大脑皮质。

GABA interneurons relatively resist ischemia-reperfusion injury,and the increasing expression of GAD65 in 3 d after ischemia-reperfusion can be a compensatory mechanism to reduce the hyperexcitability associated with ischemia-reperfusion.

GABA能中间神经元对缺血相对耐受；全脑缺血-再灌注3天，GAD65的表达增多可能是代偿性的机制，以减轻脑缺血后的高兴奋性。

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。

Essential hypertension caused by neurovascular compression of the left ventrolateral medulla was associated with malbalance of vasomotor center in the dorsal medulla. The possible pathogenesis was the following:① An irritation of the left RVLM by pulsatile compression of an ectatic vessel would increase activity of central sympathetic neuron.② Neurovascular compression at the REZ of the cranial nerves Ⅸ and Ⅹ decreased excitation of parasympathetic nerve.③ Decreased sensitivity of afferent inputs to neuron of nucleus tractus solitarii in the sensory area lead to hyperactivity of central sympathetic nervous system due to pulsatile compression of the left RVLM.④ Neurocompression of the left RVLM and REZ in the left cranial nerves Ⅸ and Ⅹ lead to an overactivity of central renin angiotensin system.

3，结论：左侧延髓腹外侧Ⅸ、Ⅹ颅神经REZ动脉血管压迫所导致的高血压的发生与左侧延髓血管运动中枢对血压的调节失衡有关，其可能机制是：①左侧RVLM在搏动性血管压迫刺激下，中枢交感神经元活性增高；②左侧Ⅸ、Ⅹ颅神经REZ受压导致副交感神经兴奋性降低；③感受区孤束核神经元接受迷走神经传入冲动的敏感性减低，导致中枢交感神经活性增高；④左侧RVLM及Ⅸ、Ⅹ颅神经REZ受压引起中枢RAS活性增加。

Chloride channels have been identified in vasucular smooth muscle cells. These channels have been shown to be involved in myogenic tone regulation and neuromuscular transmission in various vascular beds. However, whether the chloride channels are responsible for the formation of excitatory junction potentials of the smooth muscle cells in the spiral modiolar artery remains elucidated.

许多研究已证实，血管平滑肌细胞膜上存在氯离子通道，进一步研究发现氯离子通道不仅参与调节平滑肌细胞的肌原性紧张，而且参与了许多种类血管床的神经平滑肌细胞之间的信息传递，但Cl-通道及氯离子通道阻断剂对耳蜗螺旋动脉细胞兴奋性接头电位(excitatory junction potential，EJP)是否有影响，目前还不清楚。

We show gain of function of excitatory neurotransmission due to increased action-potential-evoked Ca(2+) influx and increased probability of glutamate release at pyramidal cell synapses but unaltered inhibitory neurotransmission at fast-spiking interneuron synapses.

我们发现兴奋性神经传递的功能增益来自于诱发Ca(2+)内流动作电位的增加，并可能与谷氨酸盐在椎体细胞突触中的释放增加有关，但与快速成峰中间神经元突触的抑制性神经传递无关。

Further more, because the friction force between needle and tissue is greatly dependent on muscle contraction, the excitability of the tissue near the stimulated point can be evaluated by measuring the interval between the start and stop of the needle rolling.

又由于针刺作用下肌肉的反射性收缩极大地影响了组织和针之间的摩擦力，所以测量从刺激开始到针停转所需的时间T〓还可以估计刺激点及其附近肌肉的兴奋性。

Direct primary repression consists of 'an attitude of rejection' on the part of the Central Ego towards the Exciting Object and the Rejecting Object.

直接初级的压抑是由中心自体对兴奋性客体和拒绝性客体的一种抵制态度组成的。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
