血清前白蛋白(以下称PA)是血清蛋白成分中周转快、半衰期短、在肝脏合成的蛋白质之一。故肝脏受损时合成减少,血清浓度迅速下降,可做为肝功能损害程度的一项较敏感指标。本文以火箭电泳方法检测正常人及各型肝炎患者的PA共207例。并同时检测病人的GPT、TTT、Bil、A/G及凝血酶原活动度。结果各组病例均低于正常(29.2±7.0gmg/ Pre-serum albumin (hereinafter referred to as PA) is one of the proteins that rapidly circulate in serum protein components and has a short half-life and is synthesized in the liver. Therefore, the synthesis of reduced liver damage, rapid decline in serum concentration can be used as a more sensitive indicator of the extent of liver damage. In this paper, rocket electrophoresis was used to detect PA in 207 normal subjects and various types of hepatitis patients. At the same time, the patient’s GPT, TTT, Bil, A / G and prothrombin activity were measured. Results All cases were lower than normal (29.2 ± 7.0gmg /
