Abstract
Introduction: Taking into account the patho-immune mechanisms of formation of inflammatory process in periodontium, there is a necessity for in-depth study of the
pathogenesis of periodontal diseases from the position of changes in the reactivity of the organism.
The aim: Carrying out a comparative estimation of phagocytic activity of leukocytes of animals with inflammation in periodontium with altered reactivity.
Materials and methods: Experiments were performed on 30 white rats: Group I - 10 white rats with hypoergic reaction; Group ІІ - 10 white rats with hyperergic reaction;
Group III - 10 white rats with normergic reaction - control group. Slaughter and blood sampling under thiopental anesthesia was performed 7 days after the beginning of the
experiment. The percentage of phagocytic leukocytes - phagocytic index, phagocytic number were determined and the index of phagocytic activity was calculated.
Results: The phagocytic index (Fi,%) decreased by 2,09 times (p <0,05) at hypoergic, it increased by 1,37 times (p <0,05) at hyperergic; the index of phagocytic activity (IFA)
decreased by 1.96 times at hypoergic (p <0.05); growth was 1.94 times (p <0.05) in the hyperergic group of animals. In both experimental groups, the phagocyte number (Fu)
increased by 6.25% and 41.7%, with hypoergic and hyperergic, respectively.
Conclusions: Different directions of changes of the phagocytic activity were observed: increase of these parameters at hyperergic and decrease at hypoergic. An increase in
phagocyte number was likely to indicate some autonomy of the process of phagocytosis and independence from the reactivity of the organism.
