AIM To investigate the presynaptic effects of propofol, a short-acting intravenous anesthetic, in the frog neuromuscular junction. METHODS Frog cutaneous pectoris nerve muscle preparations were prepared. A fluorescent tool (FM1-43) was used to visualize the effect of propofol on synaptic vesicle exocytosos in the frog neuromuscular junction. RESULTS Low(More)
Ouabain is a cardiotonic glycoside that inhibits the sodium potassium ATPase pump leading to sodium accumulation in nerve terminals. At the frog neuromuscular junction, ouabain induces acetylcholine release and a rapid depletion of synaptic vesicles. In the present work, we used FM1-43 vital labeling to dissect the effect of ouabain on synaptic vesicles(More)
