Activation of these two pathways was unexpectedly linked and dependent on fluid-phase activation of factor XII. 激活这两个通路意外地联系并依赖与液相XII因子激活。
The Contact Activation of Factor XII During Plasma Incubation with Blood Purification Materials 血液净化膜材在凝血过程中对凝血十二因子的接触活化
Contact system is the beginning of intrinsic coagulation pathway and comprises four components: high molecular weight kininogen, prekallikrein, factor XII ( FXII) and factor XI ( FXI). 内源性凝血途径的起始部分称为接触系统,包括高分子量激肽原、前激肽释放酶、XII因子和XI因子。
