突触的

Objective To investigate the expression and pathological function of postsynaptic density-93 (PSD-93) after rat focal ischemic middle cerebral artery occlusion/reperfusion.

目的：观察突触后密度-93基因在大鼠局灶性脑缺血再灌注皮质表达的变化，探讨其在缺血再灌注损伤中的病理作用。

These results do not support the hypothesis that excitatoryeffects of pentobarbital may alter synaptic plasticity.

这些结果不支持巴比妥的兴奋性作用能改突触可塑性的假说。

Acetylcholinesterase in the nervous system of insects is one of the most important enzymes, in the central and peripheral nervous system and the acetylcholine receptor involved nerve-nerve and nerve-muscle synaptic transmission between the action potential, and its main function is catalyzed hydrolysis cationic neurotransmitter acetylcholine. At present, in the natural products active material, the AChE ester moves the spot inhibitor physostigmine was studied clearly.

乙酰胆碱酯酶(Acetylcholinesterase，AChE)是昆虫神经系统中最重要的酶系之一，在中枢及外周神经系统中与乙酰胆碱受体一起参与完成神经-神经及神经-肌肉突触之间动作电位的传递，其主要生理功能是催化水解阳离子性神经递质乙酰胆碱。

Synaptic plasticity is an important characteristic of neural system. It is significant to the function of neural system.

突触可塑性是神经系统所具有的重要特征，也是神经系统实现其功能的重要保障。

Long-term potentiation is an important form of synaptic plasticity and a cellular model for study of learning and memory.

长时程增强是突触传递功能可塑性的重要表现形式，是研究学习与记忆的细胞模型。

This enhancement can be attributed to potentiation of retinotectal synapses.

这样的增强可以促进连接视网膜和中脑顶盖神经纤维的突触增强。

Long-term potentiation and long-term depression, two forms of synaptic plasticity, are believed to underlie the mechanism of learning and memory.

长时程增强和长时程抑制，作为突触可塑性变化的两种主要形式，被认为是学习记忆的可能机制。

This brings about an increase in the axodendritic synapses, an increase in the distance between cell bodies, and a presumable decrease in mutual electrotonic influence.

如此也使得轴树突触增加、细胞体之间的距离增加、而细胞之间相互的电紧张影响可能减少。

As special presynaptic terminal membrane protein, P38 stand for synaptic density and location.

测定P38的含量变化是监测神经系统突触形成及其功能状态的方法之一。

It was demonstrated that toosendanin was a selective presynaptic blocker, which blocked the neurotransmitter release both in peripheral and central nervous system.

已有的研究表明，它是一种作用于突触前的特异性传递阻断剂，通过抑制神经递质释放阻断神经肌肉接头和中枢神经系统的兴奋传递。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
