[Analysis of changes in erythrocyte thermoresistance in lung cancer]

Heat-induced hemolysis of erythrocytes was evaluated by the equilibrium method at 54-60 degrees C in patients with lung cancer and donors. Thermal sensitivity of patients differed from that of normal subjects and the seeming energy of erythrocyte lysis activation was lower in patients (230 kJ/mol) than in the controls (345 kJ/mol). Presumably changed structural characteristics of membrane bilayer affected the physicochemical properties of erythrocytes, determining, among other things, thermal resistance of red blood cells.
