[Proton transport during nerve stimulation].
A decrease of external pH during rhythmic excitation of the nerve of frog and squid was investigated. The level of pH was dependent on frequency excitation, concentration of sodium potassium and hydrogen ions was changed after ouabain, 2,4-dinitrophenol, tetraethylammonium and tetrodotoxin effect. The mechanism of proton transport was discussed in relation to Na-channel function.
