چکیده
Erythrocytes and plasma proteins contribrelated (p < 0.001) with the plasma ute to viscosity of blood. Therefore, blood macroglobulin concentration in g/100 ml. viscosity was measured in 16 persons with The plasma of patients with macroglobumacroglobulinemia with a cone-plate vislinemia is a non-Newtonian fluid, but at a cometer at defined shear rates. In each given shear rate the plasma viscosity is a person a significant correlation ( p < function of the macroglobulin concentra0.001) was found between hematocrit tion. These observations allowed the conand the logarithm of blood viscosity. The struction of an equation for calculation regression equation of this relationship in of blood viscosity in patients with macroeach patient was used to calculate the globulinemia when the hematocrit and blood viscosity at several hematocrits. The plasma macroglobulin concentrations are blood viscosity at a given shear rate and known. constant hematocrit was significantly cor-

T HE COLD AGGLUTININ SYNDROME (C.A.S.) is characterized by high-titre cold agglutinins, a hemolytic anemia, Raynaud phenomena in the cold, various degrees of hemoglobinuria, and sometimes gangrene. Because of the hemolysis, the syndrome is most often classified as an autoimmune hemolytic anemia. However, treatment with ACTH, corticosteroids or splenectomy, most often used in this condition, has...
