Removal of sodium channel inactivation in squid axon by the oxidant chloramine-T

We have investigated the effects of a mild oxidant, chloramine-T(CT), on the sodium and potassium currents of squid axons under voltage-clamp conditions. Sodium channel inactivation of squid giant axons can be completely removed by CT at neutral pH. Internal and external CT treatment are both effective. CT apparently removes inactivation in an irreversible, all-or-none manner. The activation pr...

On the capacity current in myelinated nerve fibres.

Different equivalent circuits are presented to describe the capacity current, Ic, of potential-clamped Ranvier nodes. The corresponding transfer functions are discussed in examining the influence of the involved parameters on size and time course of Ic. The following results were obtained: i. The duration and the amplitude of Ic increased with increasing membrane capacity. ii. The amplitude of ...

Anode break excitation in single myelinated nerve fibres.

It has long been considered that anode break excitation (ABE) is not elicitable in normal isolated nerve fibres. Quite recently, one of the authors (Konishi, 1957) found that it was due to weakness of the current applied and that, if a strong current (more than ten times the rheobase) was used, a single fibre, too, gave readily ABE. The present paper deals chiefly with threshold conditions for ...

The Permeability of the Sodium Channel to Organic Cations in Myelinated Nerve

The relative permeability of sodium channels to 21 organic cations was studied in myelinated nerve fibers. Ionic currents under voltage-clamp conditions were measured in sodium-free solutions containing the test cation. The measured reversal potential and the Goldman equation were used to calculate relative permeabilities. The permeability sequence was: sodium approximately hydroxylamine > hydr...

The Permeability of the Sodium Channel to Metal Cations in Myelinated Nerve

The relative permeability of sodium channels to eight metal cations is studied in myelinated nerve fibers. Ionic currents under voltage-clamp conditions are measured in Na-free solutions containing the test ion. Measured reversal potentials and the Goldman equation are used to calculate the permeability sequence: Na(+) approximately Li(+) > Tl(+) > K(+). The ratio P(K)/P(Na) is 1/12. The permea...
