Abstract

Appropriate concentrations of adenosine tri-, di-, and monophosphate antagonize the depressant action of procaine on isolated nerve. Some calcium ion is required in the external solution in order for these nucleotides to produce their maximum effects. When applied either to normal or sodium deficient nerves, the nucleotides do not increase action-potential amplitude.
