[Erythrocyte resistance to destructive factors during craniocerebral hypothermia].
Experiments were conducted on dogs; a study was made of the effect of cranio-cerebral hypothermia on the erythrocyte resistance to the action of chemical and osmotic hemolytics. A reduction of the body temperature of the animals from 38 to 24 degrees C led to a reduction of the chemical resistance of red cells. Erythrocytes with the maximal stability disappeared from the circulation; cells with diminished stability became prevalent. A change of erythrocytes to the group with a minimal resistance was accompanied by redistribution erythrocytosis, this indicating the loss of the hemolytic function of the erythron. The osmotic stability of red blood cells under conditions of chilling either increased somewhat or persisted of the initial level.
