[Effect of Na+ and Ca++ ion concentrations in the outer medium surrounding the erythrocyte membrane on the viscosity of blood suspensions].
A small concentration of Na+ ions (0.1 mM) causes an enlargement of the viscosity in suspensions of erythrocytes which is partial reversible by addition of Na+ ions. Ca++ ions have a conserving function. The relative viscosity is changed in the relation of concentrations of ions of Ca++:Na+ = 1:2. Changes in the viscosities are refered to change of structure of the components of membrane, especially for the part of lipids.
