Do magnetic impulses stimulate haemopoiesis?


Research into the condition and composition of cells in the marrow and blood vessels.

The hematopoietic system always reacts keenly to external actions, especially to penetrating radiation. The number of hematopoietic cells of all types (both dividing and ripening) increased in the marrow of all irradiated mice in this experiment. The researchers do not exclude the possibility that hematopoietic cells divide more rapidly and go quicker through all development stages under the influence of magnetic impulses. The higher the magnetic radiation dose, the more active its cells divided and the more weakly differentiated the precursor cells in the marrow.

Within 24 hours after irradiation was discontinued, the number of cells being in the last stage of maturation returned back to the reference level, and the number of dividing and weakly differentiated hematopoietic cells decreased practically by twice. The researchers assumed that pulsed magnetic field exposure stimulates haemopoiesis, but stimulation stops when irradiation is ceased.

The quantity of leucocytes increased in the blood of irradiated mice, which is not surprising as the leucocyte quantity depends on the organism’s functional state. The effect becomes more apparent not immediately after irradiation, as it was in case of marrow cells, but in 24 hours. Thus, 24 hours after a weekly stay in the pulsed magnetic field, leucocyte quantity in the mice’s blood increased twofold.

The researchers emphasize that their investigation touches upon far from all aspects of pulsed magnetic field influence on blood and the haematopoietic system. Specifically, the researchers did not analyze the state of mice’s health, although the growth of leucocyte quantity is often the evidence of inflammatory diseases. The hematopoietic system’s reaction to a long-standing extreme load is unknown either. After lengthy irradiation, haemopoiesis efficiency decreased twofold, but how soon it would be restored to normal level? These and other questions are still pending.
