唾液酸(SA)是许多糖蛋白和糖脂的一种组成成分,在各种癌组织中含量异常。近年的研究表明,血清中的SA可作为肿瘤严重程度和预后的指针。测定SA常用硫代巴比妥酸(TBA)光电比色法或荧光比色法,并须加亚砷酸钠作为还原剂。因亚砷酸钠
Sialic acid (SA) is a component of many glycoproteins and glycolipids and is found to be abnormal in various cancerous tissues. Recent studies have shown that serum SA can be used as a guideline for tumor severity and prognosis. SA commonly used thiobarbituric acid (TBA) photoelectric colorimetry or fluorescence colorimetric method, and the addition of sodium arsenite as a reducing agent. Because of sodium arsenite
