【摘要】 目的：建立新的纤维蛋白溶解活性（Ｆｉｂｒｉｎｏｌｙｔｉｃａｃｔｉｖｉｔｙ，ＦＬＡ）测定方法，并初步应用于心肌梗死（ＡＭＩ）患者的观察。方法：将定量受检血浆加于含有纤溶酶原（ＰＬＧ）和标准纤维蛋白的小试管中，同时加入定量的组织纤溶酶原激活剂（ｔ－ＰＡ）、硅粒，３７℃温育一小时，检测生成Ｄ－二聚体的量。结果：４０例正常人的ＦＬＡ分级在Ⅱ－Ⅲ级（占７０％），６０例ＡＭＩ患者ＦＬＡ分级在０、Ⅰ和Ⅳ级（占７３．８％）。结论：ＦＬＡ可作为一项反映人体纤溶活性的新指标。更多还原

【Abstract】 A method to determine human fibrinolytic activity (FLA) was established and preliminary used in AMI. Add patient’s plasma to fixed quantity of t PA and silica to a standardized fibrin tube containing plasminogen and incubated at 37℃ for 1 hour, then examine the D Dimer. 40 healthy persons FLA is graded on Ⅱ, Ⅲ; but 60 AMI patients is concentrated on grade 0, Ⅰ, Ⅳ(73 8%). There is individual difference in human fibrinolytic activity influenced by many factors. The FLA is an important test for evaluating the function of human fibrinolytic activity.更多还原
