The extract of Skutellaria baicalensis use in the conditions of developing cytostatic hemodepression, induced by a single administration of cyclophosphamide in a maximum tolerant doses in CBA/CaLac mice, stimulates the regenerating processes in a greater degree of erythroid and lymphoid lineages of hemopoiesis, but pantovit use – the reparation of myeloid and lymphoid lineages. Course application of Scutellaria baicalensis grades immunosuppressive effect of cyclophosphamide by stimulation of phagocyte activity of macrophages and regeneration of antibody-producing cells contents. Pantovit administration in immunized mice on the background of cytostatic immunossupression gives rise to increasing phagocyte activity of macrophages and intensification of synthetic activity of antibody-producing cells.
