D－二聚体是纤溶酶对交联纤维蛋白水解产生的一种特异降解产物。Cars[1]指出，只有D－二聚体才能反应体内凝血酶和纤溶活性。而病毒性肝炎患者血浆凝血因子水平的降低和纤溶活性的增强是肝损坏的标志之一，且凝血及抗凝因子合成的减少程度与肝脏细胞损害成正比o’‘’。本文观 D-dimer is a specific degradation product of fibrinolytic hydrolysis of crosslinked fibrin. Cars [1] pointed out that only D-dimer can reflect thrombin and fibrinolytic activity in vivo. The reduction of plasma coagulation factor levels and fibrinolytic activity in patients with viral hepatitis is one of the markers of liver damage, and the degree of reduction in the synthesis of coagulation and anticoagulant factors is proportional to the damage of liver cells.
