有研究表明，唾液有促进口腔内外伤口愈合的特性，但其内在机制尚未阐明。作者设想其机理可能是唾液蛋白制约具氧化还原活性的金属离子，使金属离子产生自由基产物的活性丧失。为厂证实这种机制，作者用不同的刺激方法，使鼠产生蛋白含量较高及较低的唾液，比较其氧化还原活性 Some studies have shown that saliva has the characteristics of promoting wound healing both inside and outside the mouth, but its intrinsic mechanism has not yet been clarified. The authors hypothesize that its mechanism may be that salivary proteins constrain redox-active metal ions that cause loss of activity of metal ion-producing free radical products. For the plant to confirm this mechanism, the authors used different stimulation methods to make the mouse produce higher protein content and lower saliva, comparing its redox activity
