| Abstract: | The focus of the study was on the reaction of by the haemopoietic system of mice subjected to impulse magnetic field. The source of the impulse magnetic field was the Shakhparonov's generator. The animals used in the experiments were mice of two strains--CBA, C57B1/6 and white non-inbred mice. These animals were exposed to impulse magnetic field during 1, 3 and 7 days. Animals were examined twice: immediately after the termination of exposure and 24 h later. The following effects were observed in the course of the experiments: an increase in the number of bone marrow cells right after the exposure termination; an increase in the number of proliferation pool cells with the increase in their mitotic activity; 1 day after the exposure termination the number of bone marrow cells was restored to the initial values, or even it decreased; the above listed bone marrow changes led to the increase in the number of peripheral blood leucocytes in 1 day after the termination of exposure. The increase of leukocyte counts was not accompanied with changes in peripheral blood cell composition. It was suggested that exposure to impulse magnetic field increases the rates of cell cycle, the cell differentiation and the maturation. |
