Abstract
Introduction: Chronic inflammatory diseases of the upper respiratory tract of both microbial and viral origin occur due to the immune deficiency of systemic and local nature. Among a large number of immunomodulation agents, a special role belongs to plant preparations, which are characterized by relative harmlessness and high efficiency, both in case of systemic and local use and they are often combined with antimicrobial agents, therefore the aim of the study was to investigate their effect on the reactions and condition of lymphoid cells of tonsilswith separate and combined use in vitro. Methods: Cell suspensions were prepared mechanically and adjusted to a concentration of 2 million/ml in medium 199 with additives. Then, Lizak preparation was added to the cells and starch solution was used in control. Imupret and Esberitox preparations were added to the culture with or without Lizak preparation. After cultivation, the levels of proinflammatory cytokine – Interleukin-1β, pro-allergic factor – Interleukin-4, Th-1 – derivative of cytokine – interferon-γ were studied in the supernatant using the «Tsitokin LLC» reagent kits (RF), as well as tissue regeneration factor – transforming growth factor –TGF-1β (Austria). The preparation was prepared from the cell pellet, in which the relative nonviable cell count was determined in a sample with trypan blue using a light microscope (Olympus CX21FS1).The statistical analysis was performed using Student's t-distribution. Results: Plant-derived preparations did not have any effect on cell viability in culture, did not reduce the level of the pro-inflammatory cytokine interleukin-1β and did not stimulate the production of the regeneration factor TGF-1β. At the same time, the combined use of plant-derived preparations and the antibacterial preparation Lizak in cell culture of tonsils was accompanied by an increase in cell viability compared to the use of Lizak preparation separately, the stimulation of the regulatory antiviral factor interferon-γ and an increase in the production of tissue regeneration factor. Conclusion: The immunomodulating properties of the antibacterial preparation Lizak and plant-derived immunomodulator Esberitox significantly differ in the points of application. Both plant-derived preparations stimulated the production of γ-interferon by tonsil cells in the presence of Lizak preparation, the transforming growth factor TGF-1β, the viability of tonsil cells was the highest with the combination of Lizak and Esberitox.
