[Cytological characteristics of erythropoiesis in thalassemia. II. Structural functional characteristics of peripheral blood erythrocytes].

In 61 patients affected with thalassaemia of various degrees of seriousness, cytological investigations were carried out on erythrocytes in the peripheral blood. The interferometrically determined changes in the dry mass of erythrocytes, the diminution of the surface potential expressed in electrophoresis, the changes in the membrane structure of erythrocytes which could be represented in the scanner electron microscope were directly dependent on the seriousness of the disease.
