Every pathology generally refers to an inadequate response to the influence brought by endo- and exotoxins, which is carried out via natural compensative and protective pathways of the body. Scientific conception of bioregulative therapy and homotoxicology implies treatment by modulation of own protective mechanisms and neutralization of already existing toxins. This endo- and exogenic homotoxins influence on the development of various immune responses of immunocompetent cells. Lymphomyosot, a complex nutural detoxifier drug, providing the effective detoxication of extracellular matrix via lymphatic system. As a huge amount of immunocompetent cells are located in the lymphatic system are, regulation of their immune responses by Lymphomyosot is very the essence of the treatment applicable to different chronic pathologies.AIMdetermining of dose-dependent immunomodulating activity of Lymphomyosot on T lymphocytes modelled system of Jurkat cells. The modelled systems of Jurkat cells, incubated under moderate oxidative stress conditions inherent chronic inflammatory processes, and stimulated with mytogene Phytohemaglutinine (PHA) was used. Effectiveness of Lypmhomyosot was studied by regulatory capacity of the cells bioviability (MTT test) immunological activity (cytokine expression, respiratory burst) and of mytogene-induced apoptosis intensity of Jurkat cells. Lymphomyosot shows antioxidant effect and dose-dependent immunomodulatory activity. Lymphomyosot, as anti-inflammatory, recovering agent is effective for profilactic aims. Low (therapeutic) doses of lymphomyosot are effective for the treatment of.
