INFLUENCE OF A VARIABLE MAGNETIC FIELD ON THE RHEOLOGICAL PROPERTIES OF BLOOD IN TREATMENT OF RHEUMATOID ARTHRITISV. V. Kirkovskii,a V. A. Mansurov,b N. P. Mit'kovskaya,a and Yu. A. Mukharskayaa UDC 612.13 A study has been made of the influence of a low-frequency variable magnetic field on the rheological properties of the blood of patients having rheumatoid arthritis as compared to healthy donors by means of rotational viscosimetry. To interpret the rheological properties use has been made of a three-parameter rheological model one parameter of which is sensitive to the action of the magnetic field; the other two parameters of the model have not been found to be affected by the magnetic field. These parameters are related to the hydrodynamic properties of an erythrocyte suspension. The influence of the magnetic field on the dependent rheological parameter has been revealed not in all the experiments, which is attributable to its selective action on proteins ensuring the interaction of the erythrocytes with each other. aBelarusian State Medical University, Minsk, Belarus; bA.
