小终板电位

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 .
