[The effect of hypothermia on the structural-functional properties of erythrocyte membranes in albino rats].

Under conditions of hypothermia intensification of lipid peroxidation, activation of phospholipase A2 and distinct alteration in lipid metabolism were found in rat erythrocyte membranes. Alterations in membrane composition correlated with a decrease in erythrocyte resistance and their stability to deformation. Erythrocytes with altered structure-functional properties might be responsible for hemodynamic impairments of tissues.
