[Immunomorphology of recurrent aphthous stomatitis].

The immunohistochemical investigation of native epithelium and recurrent aphthous stomatitis has been carried out. The A, M, G Igs, CD3 fragment of the compliment, and CD16 lymphocytes in the zone of gidropic changes and necrosis of the oral mucosa were founded The distribution of Igs, CD3 fragment of the compliment and natural killers in the same zone - prickle laminated keratinizing epithelium could be signs of immunocomplex and T-cell-dependent mechanisms of ceracinocytes dies. The results of our research prove the theory of immunotoxicity priority in oral mucosa in cases of recurrent aphthosus stomatitis.
