The article presents the results of research on the parameters of cytokine profile as mediator of immune defense, which was determined by the level of proinflammatory and anti-inflammatory cytokines in blood serum of intact animals and on the 7th day of the experimental bacterial-immune periodontitis development. Attention is drawn to the characteristic change in the indicators of the cytokine link of immunity at the early stage of the development of the experimental periodontitis. Based on these results, it was proved that the formation of the pathological process in the periodontal complex is accompanied by an imbalance in the system of cytokinogenesis for the early period of the inflammatory reaction development, indicating their modulating role in the regulation of the immune-inflammatory response in this modeled pathological process.
The aim of the study – to determine pathogenetic role of cytokinogenesis for early stages of the experimental bacterial-immune periodontitis development.
Materials and Methods. The investigations was performed with use of white, non-breeding, clinically healthy male rats 150–200 g of weight in conditions of vivarium. Experimental animals were randomly selected and divided into two experimental groups: the group 1 – intact animals, control; the group 2 – animals with an experimental periodontitis on the 7th day. Experimental bacterial-immune periodontitis in experimental animals was caused by introducing into the tissue of the periodontal complex a mixture of microorganisms diluted with egg protein [10]. In order to strengthen the immune response, an injection into the rat's foot of the full Freund's adjuvant was performed at the same time. For further research the blood serum was selected, in that was determined the content of tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), interleukin-4 (IL-4), interleukin-10 (IL-10).
Conclusion. Formation of experimental periodontitis is accompanied by a complex of pathological changes characterized by reliable progressive increase of proinflammatory cytokines for the early stage of inflammatory reaction development, that prove participation of TNF-α and IL-1β in the periodontal diseases pathogenesis.
