The effection of mast cells ( MC) on collagen metabolism of oral submucous fibrosis ( OSF) induced by aqueous areca nut extracts ( AANE) in rats was studied by transmission electron microscope, histochemical and biochemical analyses.

Method: Human oral mucosa keratinocytes were isolated, cultured, stimulated with AANE, The supernatant was aspirated and the level of TNF α was detected using radioimmunoassay.
