Arrhenius dependencies of permeability coefficients for the studied substances were shown to be underwent the series of breaks within the following temperature limits: 8-12, 18-20 and 28-30ï‚°C (being known as the critical ones for some functional indices of biological membranes) with sharp changes in activation energy (EA). Some possible mechanisms of thermoinduced changes in parameters of non-electrolytes permeation via erythrocyte membrane are discussed.</p> ER -
