title: [Conductivity and structural transitions in bilayer lipid membranes].
abstract: 5 structural transitions were found in bilayer lipid membranes (BLM) from egg lecithin (EL) within the temperature range 14-44 degrees C. In the transition zone BLM conductivity abruptly increases, in some cases current fluctuations of the order 150 pC of the channel type are initiated. The transition temperatures observed in BLM from EL coincide with those in biological membranes. The cause of this phenomenon is discussed, as well as possible use of these BLM in the region of structural transition as a model of cellular receptor to electromagnetic fields.
