| Summary: | Modulating influence of electric impulses, visible light, some microelements is studied in parameters which are near to physio-logic ones on life activity of progenitor and mature cells of blood system in vitro and in situ. Content of granulocyte and fibroblastoid colony-forming units, concentration of colony-stimulating and colony-inhibiting activities, their concentration were determined , myelograms and morphologic signs of myelocariocytes apoptosis and necrosis were scored, saturation by chrom ions of peripheral blood erythrocytes was studied in mice bone marrow. The results showed that cell effects of physical-chemical influ-ences are small specific. Nevertheless, one may perform both positive and negative regulating influence on life activity of stromal precursors in dependence of energy density and stimulus concentration . The effect is due not only by direct but mediated reactions regulating direction and intensity of metabolic intracellular processes. It is suggested that one of target cells capable of change in-crease program of hemopoietic and stromal cells-progenitors of bone marrow in dependence of physical stimulus strength are lym-phocytes. |
