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.

方法：通过体外培养口腔黏膜角朊细胞，用不同浓度槟榔提取物对其进行干预，放射免疫方法检测不同干预时段培养上清中的肿瘤坏死因子α浓度。

Result: The concentration of TNF α increased after keratinocytes were stimulated by AANE for 12 hours or longer time.

结果：槟榔提取物干预角朊细胞12h后肿瘤坏死因子α的量开始增加；

Result: The level of NO produced by endothelial cells was inhibited by AANE.

结果：槟榔提取物能抑制体外培养的内皮细胞分泌NO。
