MAST CELLS AND GLYCOSAMINOGLYCANS IN THE MUCOUS MEMBRANE ORAL CAVITY IN BEHCET'S DISEASE

Mast cells (MC) and glycosaminoglycans (GAG) in various zones of oral mucosa are investigated during remission and aggravation of Behcet disease (BD) in 10 patients (8 men and 2 women; average frequency of aggravations in a year - 4.5). Bioptats (biopsy material) of various zones of oral mucosa arc investigated histochcmically. The MC arc identified by 0.05 percent thioninc solution according to Hassanov's prescription, as well as by GAG-PAS-reaction under the control of amylase, and by fast blue and strong garnet CBS [ 1 J. The statistical correlation between frequency of aggravations of BD and histochemical quantitative indices of the MC and GAG is studied.
