Abstract
. The purpose of the study was to evaluate the immunomodulatory properties of the dry extract of Jerusalem artichoke herb in terms of weight (thymus, spleen), number of cells (thymus, spleen, bone marrow) of the immune system organs, indicators of cellular and humoral immunity in mice on a model of experimental immunodeficiency induced by the cytostatic methotrexate.
Materials and methods. The study of the immunomodulatory activity of the dry extract of Jerusalem artichoke herb was evaluated by the ability to restore the mass (thymus, spleen), the number of cells (thymus, spleen, bone marrow) of the immune system organs, indicators of cellular, humoral immunity and phagocytic activity of peritoneal macrophages of outbred mice under conditions of immunosuppression induced by methotrexate, to the level of intact mice, in vivo.
Results. Analysis of the effect of the dry extract of Jerusalem artichoke herb in in vivo systems found that the dry extract of the herb Helianthus tuberosum L. had no effect on the mass (thymus, spleen) and the number of cells (thymus, spleen, bone marrow) of the immune system organs, the severity of the delayed-type hypersensitivity reaction, antibody production, phagocytic activity of peritoneal macrophages of intact mice and restored these parameters of the immune system in animals treated with the cytostatic methotrexate to the level of intact animals, which was comparable to the effect of the reference drug "Immunal".
Conclusion. The dry extract of Jerusalem artichoke herb can be considered as a promising agent that restores the parameters of cellular, humoral immunity, the phagocytic activity of peritoneal macrophages and the cellular composition of the immune system under conditions of immunosuppression induced by methotrexate, to the level of intact animals, the effectiveness of which is comparable to the effect of the comparator drug "Immunal
