The process of myelopoiesis in guinea pigs under conditions of a static magnetic field.
Myelopoiesis and distribution of white blood cells in peripheral blood in 210 guinea pigs related to the duration and induction of an applied magnetic field were studied. Exposure to a static magnetic field of induction 0.05 T and 0.3 T each day for 7 weeks at 1 h per day led to a decrease of basophilic and polychromatophilic erythroblasts, an increase in the percentage of cells of the granulopoietic (neutrophilic myelocytes, eosinophilic metamyelocytes, band neutrophils, band basophils, segmented eosinophils) and lymphopoietic system, a slight increase in plasma cells and decrease in the percentage of megakaryocytes in bone-marrow. In the peripheral blood the percentage of lymphocytes was increased. The observed changes were independent on the duration of magnetic field action within the magnetic induction value.
