血清前白蛋白（简称 ＰＡ）是人体内一种快速转运蛋白之一，其分子量约为５．５万，半衰期１．９ｄ。该蛋白主要由肝细胞制造，能敏感地反映肝实质损害，肝细胞受损时ＰＡ降低。目前，对ＰＡ在肝脏损害时的变化报道较多，但在儿童急性血吸虫感染时的ＰＡ检测资料极少。我们于１ Pre-serum albumin (PA) is one of the rapid transporters in the human body with a molecular weight of about 55,000 and a half-life of 1.9 days. The protein, which is made primarily from hepatocytes, can sensitively reflect the parenchymal damage of the liver and reduce PA when hepatocytes are damaged. At present, there are many reports about the changes of PA in the liver damage, but there is very few PA test data in children with acute schistosomiasis infection. We are at 1
