[Study of the effect of low temperatures and organic solvents on the structure of model membranes using fluorescent probes].

By means of the fluorescence probes pyrene, DSP-12 and n-terphenyl the effect of low temperature, glycerol and 1,2-propylene glycol on the structure of lecithin liposomes and proteoliposomes formed by lecithin and cytochrome P-450 has been studied. Freezing-thawing and cryoprotectants were shown to modify surface area and internal volume of the lipid bilayer.

[Erythrocyte membrane permeability of Citellus undulatus during hibernation].

We have studied the influence of the erythrocyte hypothermic storage of long-tailed ground squirrels at various physiological states and white mongrel rats on the impairment of the barrier function of their membranes for ferricyanide. The membranes of sleeping and awakening ground squirrels demonstrate the highest stability (the structural integrity is sustained for 3-3,5 months), meanwhile rat blood erythrocytes maintain the barrier function only for 2 weeks. Beside structural and viscous changes in the erythrocyte membrane and the cytosol of hibernating ground squirrel an important role in maintaining barrier function under conditions of hypothermic storage is played by the content of animal blood plasma. Appearance of a non-typical EPR spin probe spectrum in some ground squirrel blood samples in non-equilibrium state of entering or arousing from hibernation has been observed.
