Objects of research: rats - blood, static magnetic field, iron-bearing magnetic material. The aim of the research is the study of the changes in rheological rate of rats - blood (hemoglobin, hematocrit, erythrocyte aggregation, whole protein) under the influence of the magnetic field and the assessment of the protective properties iron-bearing materials. Indicators of blood of rats: hemotocrit and index aggregation of erythrocyte had changed under the influence of magnetic field with inductance in 100 mT on 8,1-8,3 per cent in comparison with control sample. The rate of whole protein and hemoglobin changed by 26-28% at reference template. This pattern can be explained possible by the transformation in the structure of the protein under the influence of the magnetic field. The rates of hematocrit and erythrocyte aggregation in rats - blood changed by 2-2,7%at reference template and the rates of whole protein and hemoglobin changed by 11-16% with the use iron-bearing protective material. It-s a fact, that the iron-bearing protective material has protective properties and can be recommended for practical application.
