Abstract

Background: The magnetobiological effect of the weakened magnetic field of the Earth is of interest due to the consequences of the long stay of astronauts in space.
Objective: The rheological properties of erythrocytes in a weakened magnetic field of the Earth are investigated.
Methods: Osmotic gradient ektacytometry, aggregometry.

Results: A study of the rheological properties of erythrocytes of blood rats in vitro, exposed at a temperature of 0°C in a natural and weakened magnetic field of the Earth, was carried out. It is established that a weakened magnetic field leads to a decrease in the rate of hemolysis, the average body volume, transformation, and decrease in the specific surface of the erythrocyte, potentiates the weakening of the deformation and aggregation properties.

Conclusions: The results of the work should be taken into account not only to predict the rheological behavior of the blood system when the natural magnetic field is weakened but also to optimize the conditions for the long-term storage of donor blood.
