THE CHANGES IN CLONES OF ANTIGENEREACTIVE IMMUNE LYMPHOCYTES TO DIFFERENT MICROORGANISMS DURING PARODONTITIS

 The activation of clones of immune lymphocytes to streptococci takes place at parodontitis. The number of noted lymphocytes significantly increases in the blood of patients with parodontitis  as compared to healthy persons having intact parodontium (12.7±0.3 versus 3.87±0.32, P<0.001). At various forms of parodontitis the growth of antigenreactive lymphocytes  is expressed with different degrees.  Particularly sharp increase is observed during severe forms of parodontitis as compared to average and light forms (the number of antigenereactive  lymphocytes to streptococci in the blood respectively made up 16.9±0.59, 12.8±0.23, 9.5±0.27, P<0.001).  As to immune lymphocytes to staphylococci and actinomycete, their activation was not revealed at parodontitis. The quantitative indices of the noted clones of lympho- cytes in the blood did not essentially differ from analogical indices of healthy individuals (an average amount of immune lymphocytes to staphylococci and fungi made up 4.3±0.26 and 3.84±0.29, P<0.05 as compared to healthy individuals). Thus, the increase of number of lymphocytes having receptors to streptococci in the blood has been first established at parodontitis and its intensity was in direct correlation to the degree of the generalization of the process. Proceeding from the aforesaid, it is possible to think that the leukocytes accumulated as a result of chemotaxis in response to microbial aggression in the inflammatory focus, developed in the tissues of  parodontium, especially neutrophils and macrophages induce the disorganization of streptococci and their antigens, including the release of antigens common to the tissues of the organism, followed by the development of reciprocal protective and destructive immune processes.
