终板电位

钙离子和神经活动对川栋素引起的小终板电位频率变化的影响

Effects of calcium ions and nerve impulses on changes in miniature end-plate potential frequency produced by toosendanin

SP也能降低终板电位（epp）幅度；使epp量子含量发生先兴奋后抑制的双相变化。

It also reduced he amplitude of end plate potential ( epp ), and resulted in an initially excitatory and then inhibitory change of epp quantal content .

提高正常标本溶液中的Ca~（++）浓度（从2mM到16mM），小终板电位的发放频率亦随之增加。

The MEPP frequency was raised about 3 times when the Ca ~ ( + + ) concen-tration of Krebs solution was elevated from 2 to 16 mM .

1952年，Fatt和Katz首先在蛙NMJ记录到自发性小终板电位（MEPP），并证明它是运动神经末梢自发释放递质性乙酰胆碱（ACh）的结果。

Early in 1952 , Fatt and Katz first recorded spontaneous miniature end-plate potentials ( MEPP ) in frog NMJ , and showed that they were the result of spontaneous release of transmitter substance , acetylcholine ( ACh ), from motor nerve terminals .

随后，突触后膜开始逐渐去极化，最大去极化27.0mV。62.7min后小终板电位（mEPP）频率逐渐增高，到70.3min达到最高频率，比给药前增加了32倍。

Hereafter postsynaptic membrane potential was depolarized gradually , and the maximum depolarization value was 27 . 0 mV . The frequency of mEPP increased markedly after 70 . 3 min MTX administered , 32 folds compared with control .

采用玻璃微电极记录方法，选取大鼠膈神经&膈肌标本，观察了重症肌无力患者血清对健康大鼠与脾气虚大鼠小终板电位（MEPP）的影响。

To study the effect d serum from myasthenia gravis patient on minor-end-plate electric potential ( MEPP ) of Spleen-Qi Defi - ciency ( SQD ) rats and healthy rats by selecting phrenic nerves-diaphragmatic muscles as samples and recorded by glass micro - electrode .

维库溴铵对大鼠膈肌神经肌肉接头微终板电位和终板电位幅度和频率的影响

Effects of vecuronium on neuromuscular junction miniature endplate potentials and endplate potentials in rat diaphragm

但不影响微终板电位的发放频率，也不影响肌纤维的静息膜电位。

Neither the frequencies of miniature endplate potential nor the resting membrane potential of the muscle were changed by fraction ⅸ .

重症肌无力患者血清对脾气虚大鼠小终板电位影响的实验研究

Experimental Study of Effect of Serum from Myasthenia Gravis Patient on Minor - End - Plate Electric Potential of Spleen-Qi Deficiency Rats

记录急性迟发性脓毒血症和非脓毒血症大鼠的离体横膈运动终板上的终板电位、酰胆碱电位和电紧张电位。

Endplate potentials , acetylcholine potentials , and electrotonic potentials were recorded from the motor endplates of isolated diaphragms from acute late septic and non septic rats .
