[In vitro influence of albumin, gammaglobulin and fibrinogen on the sedimentation rate and the rheological behaviour of the red cell (author's transl)].

The complexity of the mechanisms which enter into play in the phenomenon of erythrocyte sedimentation have for long aroused the curiosity of research workers. A simultaneous study of this parameter and of the viscosity, of the relative zeta potential together with the osmotic fragility, led us to appreciate the respective actions of three isolated plasma proteins : albumin, immunoglobuin G, fibrinogen, on the ESR and on the rheological properties of the red cell.
