Interaction of Glutamate-and Adenosine-Induced Decrease of Acetylcholine Quantal Release at Frog Neuromuscular Junction

Abstract

In a frog neuromuscular preparation of m. sartorius, glutamate had a reversible dose-dependent inhibitory effect on both spontaneous miniature endplate potentials (MEPP) and nerve stimulation-evoked endplate potentials (EPP).
