前白蛋白(PA)是由4个相同亚基组成的四聚体,相对分子量61 000,生物半衰期1.9天(白蛋白17~21天)。目前,临床主要用于评估肝功能损害和营养不良,同时也是药物中毒引起肝损害的敏感指标~([1])。血清PA水平受炎症状态、组织坏死等影响,大部分学者认为PA是一种非特异性的宿主防御物质,可以清除感染期间释放于循环中的部分有毒代谢物。目前已证
Prealbumin (PA) is a tetramer composed of four identical subunits with a relative molecular weight of 61 000 and a half-life of 1.9 days (albumin 17 to 21 days). At present, the clinical is mainly used to assess liver dysfunction and malnutrition, but also a sensitive indicator of liver damage caused by drug poisoning (1). Serum PA levels by the inflammatory state, tissue necrosis and other effects, most scholars believe that PA is a non-specific host defense substances, can be cleared during the release of some toxic metabolites in the circulation.
