    por Blaustein, M. P.
    Publicado 1968
    “…These barbiturates also slow the rate at which the sodium conductance turns on, and shift the normalized sodium conductance vs. voltage curves in the direction of depolarization along the voltage axis. …”

    Publicado 1979
    “…Long alkyl chain quaternary ammonium ions (QA), the local anesthetics (LA) tetracaine and lidocaine, imipramine, and pancuronium cause inactivation of the alamethicin-induced conductance in lipid bilayer membranes. The alamethicin-induced conductance undergoes inactivation only when these amphipathic compounds are added to the side containing alamethicin. …”

    “…These results argue that K ions can enter the CTX-blocked channel from the internal solution to reach a site located nearly all the way through the conduction pathway; when K+ occupies this site, CTX is destabilized on its blocking site by approximately 1.8 kcal/mol. …”

    “…The presence of internal Mg-ATP produced a number of changes in the K conductance of perfused giant axons of squid. For holding potentials between -40 and -50 mV, steady-state K conductance increased for depolarizations to potentials more positive than approximately -15 mV and decreased for smaller depolarizations. …”
