Introduction: Complex natural medicines are successfully used in various inflammatory diseases of the upper respiratory tract, but their immunomodulatory activity has not been studied enough, in particular in case of Cinnabsin. Therefore, the aim of the study was to determine the effect of the medicine on the production of cellular and humoral factors of immunity and inflammation by tonsil cells of the children.
Materials and methods: The studies were performed in vitro using 24-hour cultures of children`s pharyngeal tonsil cells after adenotomy. Altogether 90 samples of cultures were examined before and after the influence of the medicine. The effect of complex natural medicine Cinnabsin on the cells production of various cytokine groups (γ-interferon, interleukins 1, 4, 10), expression of surface antigens CD14+, CD16+, and cytolytic activity of natural killer cells were investigated. Methods of enzyme immunoassay, light microscopy and cellular cytolysis with xenogenic targets were used. Statistical processing was carried out with the Student`s non-parametric criterion, and the Fisher`s angle transformation method when processing ratios.
Results: Cinnabsin, both in dosage 10 μg/ml and 100μg/ml, increased the number of cells with the expression of the antigen CD16+ and partially CD14+, activated the natural cytotoxic cells of the tonsils, reduced the production of IL-1β and increased the production of IL-10 and γ-interferon in cell culture.
Conclusion: According to the sum of the effects and the immunomodulation vectors, it is possible to state the modulating effect of the medicine on the activity of various immunity reactions, which allows concluding the pronounced anti-inflammatory and antiviral effect of Cinnabsin.
