硫氰酸盐是唾液中正常成分,它的研究始手1814年,以后陆续有很多的研究报告。早期由于测定方法的不同,其含量变异较大。但有一事实,即唾液中硫氰酸盐浓度高于血清中十几倍乃至几十倍,说明唾液腺具有合成或浓缩硫氰酸盐的能力。硫氰酸盐也是机体对氰化物解毒代谢产物,在唾液中测定硫氰酸盐含量,也可能反映机体摄入氰化物的水平。目前,对唾液中硫氰酸盐浓度的生理意义还不甚明了,多数认为与口腔内杀菌作用机制有关。最近曾有一篇(Boyland等)报导唾液中硫氰酸 Thiocyanate is the normal component of saliva, its research began in 1814, after another have a lot of research reports. Early determination of the different methods, its content variation. However, there is a fact that the concentration of thiocyanate in saliva is more than ten or even ten times that in serum, indicating that the salivary gland has the ability to synthesize or concentrate thiocyanate. Thiocyanate is also the body's detoxification of cyanide metabolites, thiocyanate content in saliva, may also reflect the level of cyanide intake of the body. At present, the physiological significance of the concentration of thiocyanate in saliva is not clear, most of which are related to the mechanism of oral sterilization. A recent article (Boyland et al.) Reported thiocyanic acid in saliva
