微量元素在体内具有特异的生理功能。微量元素的不平衡可能在某些疾病的病因和发病机制中起重要作用。近年发现,锌缺乏可能引起一系列疾病,缺锌与口腔粘膜上皮的不全角化有密切关系。Follis(1941)给大白鼠以低锌食物,发现上皮出现不全角化现象是缺锌的唯一反应。同时指出,不全角化现象主要发生于皮肤病和口腔粘膜病,颊部粘膜上皮和舌上皮也有不完全角化现象,H Mèhant等(1976)报道血清锌的含
Trace elements in the body has a specific physiological function. The imbalance of trace elements may play an important role in the etiology and pathogenesis of certain diseases. In recent years, found that zinc deficiency may cause a series of diseases, zinc deficiency and oral mucosa epithelial insufficiency are closely related. Follis (1941) to rats with low-zinc foods, found that epithelial hyperkeratosis phenomenon is the only response to zinc deficiency. Also pointed out that the phenomenon of incomplete keratosis occurs mainly in skin diseases and oral mucosal disease, cheek mucosal epithelium and tongue epithelial also have incomplete keratosis, H Mèhant et al (1976) reported serum zinc
