纤维蛋白溶解机制是一系列蛋白激酶催化的连锁反应过程 ,可分为纤溶酶原在激活物激活下转变为纤溶酶和纤溶酶水解纤维蛋白 (原 )及其他蛋白质 (如ＦⅤ ,Ⅷ和等 )两个阶段。凝血因子Ⅻ ,作为接触激活系统的激活物的前体 ,在固相或液相激活系统的激活下生成Ⅻａ ,其可以直接或 Fibrinolytic mechanism is a series of protein kinase catalyzed chain reaction process can be divided into plasminogen activator activated plasmin and plasmin hydrolysis of fibrin (prot) and other proteins (such as FV, ​​Ⅷ And , etc.) two stages. The clotting factor Ⅻ, which acts as a precursor to an activator that contacts the activation system, generates Ⅻa upon activation of the solid phase or liquid phase activation system, which can be either
