[Changes in the osmotic resistance of the erythrocytes in thermal trauma and the role of free-radical oxidation].

Reduced erythrocyte osmotic resistance against the background of elevated blood level of TBA-reactive products was recorded in experimental thermic injury (of IIIa-IIIb degree, involving 15-20 per cent of the body surface). Under the influence of alpha-tocopherol, parallel with the restriction of free-radical oxidation (FRO) activity, there was a rise in erythrocyte membrane osmotic resistance. FRO participation in the mechanisms of reduced erythrocyte osmotic resistance in thermic injury is discussed.
