涎酸(唾液酸,Sialic acid)广泛分布于动物组织及微生物中,是多种多糖粘蛋白及糖蛋白与某些脂类的组分之一,是这些物质发挥生物效应的重要功能部分。1936年,Blix首先从牛颌下腺分离出涎酸而得名。国外从五十年代就开始涎酸的研究。我国近年来也有报道,并受到临床的重视。为进一步探讨涎酸测定在临床医学上的广泛应用,现将国内外有关资料综述如下。
Sialic acid (Sialic acid) is widely distributed in animal tissues and microorganisms. It is one of the components of many polysaccharide mucins, glycoproteins and certain lipids, and is an important functional part of these substances exerting biological effects. In 1936, Blix was first named after the isolation of tannic acid from the submandibular glands of cattle. Foreign countries began research on tannins since the 1950s. China has also reported in recent years and has received clinical attention. In order to further explore the wide application of citric acid determination in clinical medicine, the relevant data at home and abroad are summarized as follows.
