Modifications of the erythrocyte deformability alter the effect of temperature on the relative viscosity of human blood.
The relative viscosity of normal red cell suspensions is independent of temperature at high shear rates. The relative viscosity of suspensions with normovolemic sphered erythrocytes having a reduced deformability, however, is higher at 37 degrees C then at 20 degrees C. It is concluded that the changes of the lipoprotein configuration within the erythrocyte membrane which are proposed to be involved in the disc-sphere-transformation of the red cell, depend on temperature and are responsible for the increased relative viscosity at 37 degrees C.
