Histochemical Expression of Mast Cell Chymase in Chronic Periodontitis and Cyclosporine-Induced Gingival Overgrowth
Figure 1
The mast cell and mast cell chymase expressions were studied in the gingival tissues. The cells with metachromatic reaction (arrows) in connective tissue of (a) control; (b) DIGO tissues (toluidine blue, ×400). Enzyme histochemical expression of mast cell chymase in (c) control; (d) DIGO tissues (×400). Chymase positive mast cells are numerous in the DIGO tissues.
