title: [Single ion channels and macroscopic conductivity of bilayer lipid membranes].
abstract: The dynamic conductivity of bilayer lipid membranes unmodified by ionophores in current ranges of 10(-12)-10(-10) A was studied. On the current voltage characteristics the jumps of dynamic conductivity in the voltage ranges near zero and disruption value were observed. The lifetime of these jumps was 1-5 s. It was shown that these effects were due to electrostriction phenomena and defects in the bilayer lipid structure correspondingly. Apparently, lipid peroxidation products participate in the building of defects in lipid bilayers.
