title: [Dynamics of synaptosomal membranes in experimental neurosis in animals using donor-acceptor pairs of luminophores].
abstract: Dynamic of synaptosomal membrane's structural parameters (fluidity, protein clusterization, thickness of lipid bilayer) during chronic (15 days) psychogenic stress was compared with kinetic of membrane bound enzyme--Na,K-ATPase. For evaluation of structural changes in membranes a special multiprobe method, based on the use of fluorescent probes ANSA and pyrene, fluorescence of endogenous tryptophane and inductive-resonance energy transfer was designed. The data obtained indicates correlation between structural and functional changes in synaptosomal membranes. It was also concluded that the multiprobe procedure used is a sensitive and adequate tool for investigation of structural changes in biomembranes.
