妊娠期母体发生极其复杂的变化,其中虽以子宫增大等性器官的变化最为显著,但其他系统,如内分泌、免疫等方面以及血凝、纤溶及激肽产生系统也都有明显改变。一、血凝、纤溶及激肽产生系统的相互关系参与血凝、纤溶及激肽产生系统的酶与胰蛋白酶一样,其活性中心具有丝氨酸基,氨基酸的排列也多具有共同的结构,可统称为丝氨酸蛋白分解酶。三者关系密切,并与补体系统有关。这些蛋白分解酶有很重要的生理作用,即血凝系统与血小板一起参与止血和创伤的修复,纤溶系统对血栓进行溶 Pregnancy maternal extremely complex changes, although the increase in the uterus and other organs of the most significant change, but other systems, such as endocrine, immune and other aspects as well as hemagglutination, fibrinolysis and kinin production system has also been significantly changed. First, the relationship between coagulation, fibrinolysis and kinin system involved in coagulation, fibrinolysis and kininogenesis system of enzymes and trypsin, the active center has a serine group, amino acid arrangement also has more common structure, Can be collectively referred to as serine proteolytic enzyme. The three are closely related, and the complement system. These proteolytic enzymes have a very important physiological role, namely the hemagglutination system and platelets are involved in the repair of hemostasis and trauma, fibrinolytic system of thrombosis
