[Effect of hypothermia on Na(+)-K(+)-ATPase activity and hemoglobin binding in the rat erythrocyte membranes].
The activity of Na+/K(+)-ATPase and hemoglobin binding in membranes of rat erythrocytes during hypothermia (20 degrees C) was studied. Hypothermia causes an increase in hemoglobin binding and a decrease in Na+/K(+)-ATPase activity. It was found in in vitro experiments that the addition of hemoglobin to the membranes does not affect the Na+/K(+)-ATPase activity in control animals and decreases the activity of the enzyme in hypothermia.
