ОЦЕНКА ИММУНОМОДУЛИРУЮЩЕГО ДЕЙСТВИЯ СУХОГО ЭКСТРАКТА ТРАВЫ TRIFOLUM PRATENSE L.

Abstract

The purpose of the study was to determine the optimal concentration of dry extract of the herb Trifolium pratense L. to reduce the immunosuppressive effect of methotrexate on the lymphoid organs of mice. Materials and methods. The immunomodulatory effect of the dry extract of the herb Trifolium pratense L. was assessed by the ability to bring the weight and cellularity of the lymphoid organs of the immune system of mice when exposed to methotrexate to the level of intact animals. Experimental studies were performed on 129 mature outbred white male mice. Immunomodulatory activity was assessed by determining the mass of the thymus and spleen, the number of thymocytes, splenocytes and myelokaryocytes. Results. A study of the immunomodulatory properties of the dry extract of the herb Trifolium pratense L. revealed that this phytosubstance in the selected dosage of 50 mg/kg did not change the weight and number of cells in the thymus and spleen of mice, including the number of bone marrow cells, while restoring the weight and cellularity of the immune system organs of mice exposed to methotrexate, which is comparable to the effect of the immunomodulator «Immunal». Conclusion. Dry extract of the herb Trifolium pratense L. at an optimal dosage of 50 mg/kg can reduce the immunosuppressive effect of methotrexate, which may be due to the high content of phenolic compounds. This herbal medicine can be considered as an immunomodulatory herbal remedy.
