title: [Effect of armin on frog myelinated nerve fibers].
abstract: Study of the action of armin on the nodes of Ranvier in isolated nerve fibers of the frog has demonstrated that armin at concentrations over 4 X 10(-7) M produces the growth of the input resistance of the nodes of Ranvier at the expense of the decreased leakage conduction. At concentrations of 4 X 10(-6) and 4 X 10(-5) armin leads to a shift of the firing level of action potentials towards more positive values.
