The study was carried out on the toad seiatic-sartorius preparation. Besides prolonging the action potential of the nerve fibre the nickel ion called forth repetitive discharges of the nerve and depressed neuromuscular transmission reversibly. The transmission could be easily restored by increasing the calcium concentration, but was not affected by prostigmine. The time course of the falling phase of the end-plate potential (e.p.p.) after treatment with nickel was similar to that after d-tubocurarine. In the...

The study was carried out on the toad seiatic-sartorius preparation. Besides prolonging the action potential of the nerve fibre the nickel ion called forth repetitive discharges of the nerve and depressed neuromuscular transmission reversibly. The transmission could be easily restored by increasing the calcium concentration, but was not affected by prostigmine. The time course of the falling phase of the end-plate potential (e.p.p.) after treatment with nickel was similar to that after d-tubocurarine. In the period of complete neuromuscular block the frequency of the miniature e.p.p.'s remained unchanged and occasionally was somewhat increased. Nickel affected neither the sensitivity of the end-plate region to acetylcholine (ACh), nor the time course of the electrotonic potential of the muscle membrane. The resting potential of the muscle fibres was not affected by nickel, but the critical level of depolarization for generating spike discharge was increased to some extent. It is supposed that the diminution of ACh release at the motor nerve endings by nerve impulse is probably the chief cause of the neuromuscular block produced by nickel ions.

一定濃度的鎳离子可引起神經干的重复发放及神經肌肉傳递阻滞;这种阻滞是可逆的。它不能被新斯的明所解除。鎳阻滞时,終板电位下降相的时程与箭毒阻滞时的无显著差別。此时自发微終板电位的頻率不变,有时还有所增加。鎳离子对乙酰胆硷在終板区引起的去极化电位、肌纤維膜的电性质和肌纤維的靜息电位皆无明显影响。鎳离子虽然在一定程度上可提高肌纤維的临界去极化值,但高濃度鈣离子却能解除鎳的阻滞作用。根据这些結果,我們认为,神經末棺在神經冲动的作用下釋放乙酰胆硷的减少可能是鎳引起傳递阻滞的主要因素。

Electron microscopic observations showed that in normal rat diaphragm themean length of the satellite cells was much greater in the end plate region thanat some distance outside it,but their number in the two regions did not differ signi-ficantly.Three days after denervation or after treatment of the phrenic nervewith colchicine,correlated with the appearance of acetylcholine hypersensitivity,there was an increase in the mean length but not in the average number of thesatellite cells.This increase in length was more prominent outside the end plateregion than inside it.When denervation was accompanied by treatment withActinomycin D,the post-denervation alteration in length of the satellite cells wasprevented together with the suppression of the development of ACh hypersensitivity.

In the present work, tetrodotoxin (TTX) was used to chronically block theconduction of impulses of the rat sciatic nerve, and the changes of action potentialsof inactivated muscle fibres were examined. Action potentials intracellularlyelicited were recorded from the end-plate region of the fast-twitch muscle extensordigitorum longus (EDL) and slow-twitch muscle soleus (SOL) muscle fibres inactivat-ed for up to 7 days. Similar to denervation, long-term inactivation led to graduallydecreasing of the overshoot...

In the present work, tetrodotoxin (TTX) was used to chronically block theconduction of impulses of the rat sciatic nerve, and the changes of action potentialsof inactivated muscle fibres were examined. Action potentials intracellularlyelicited were recorded from the end-plate region of the fast-twitch muscle extensordigitorum longus (EDL) and slow-twitch muscle soleus (SOL) muscle fibres inactivat-ed for up to 7 days. Similar to denervation, long-term inactivation led to graduallydecreasing of the overshoot and rise rate of action potentials and appearance ofTTX-resistant action potentials in a few fibres on the fourth day. On the seventhday the TTX-resistant action potential was found in almost all of tested fibres(100%SOL and 90% EDL fibres). But, these changes induced by inactivation were lessthan those by denervation. After removal of blockade, the overshoot and riserate of action potentials gradually returned to the control level, and the actionpotentials could no longer be elicited in the presence of TTX. The time course,with which both the recovery of parameters of action potentials and the disap-pearance of TTX-resistant action potentials proceeded, was faster in EDL than inSOL. The mechanism of inactivation-induced change of action potentials ofmuscle fibres and the possible reason for the difference in the recovery processbetween EDL and SOL are discussed.

用河豚毒素(TTX)慢性阻断大鼠坐骨神经的冲动传导,使后肢不活动,经过不同时间(最长7d)后离体观察了快肌伸趾长肌(EDL)和慢肌比目鱼肌(SOL)肌纤维终板区的诱发动作电位。我们发现在不活动期间动作电位超射和上升速率逐步下降,并从第4天起部分肌纤维能在含有1×10~(-7)g/ml TTX的溶液中被诱发产生动作电位(称抗TTX动作电位),待至第7天时全部SOL肌纤维和90%的EDL肌纤维都能被诱发出抗TTX动作电位。与去神经肌纤维相比,不仅抗TTX动作电位出现较晚,并且其超射和上升速率较低。在去掉TTX阻断使肌肉恢复活动后,动作电位超射和上升速率渐趋恢复,抗TTX动作电位逐渐消失。无论是动作电位的恢复还是抗TTX动作电位的消失,EDL肌纤维均快于SOL肌纤维。本文还讨论了不活动化使肌纤维动作电位变化以及快、慢肌差别的可能原因。
