Using a sensitive radioactive method that measures selectively the evoked release of acetylcholine, it was demonstrated that, when stimulating at 50 Hz, tubocurarine or pancuronium 2 X 10(-5) mol litre-1 or hexamethonium 10(-3) mol litre-1 significantly decreased the evoked release of acetylcholine in the mouse in vitro phrenic nerve-hemidiaphragm preparation.
