补体系统补体系统是新鲜血清中存在的一组多分子血清蛋白,各成分在正常情况下,以非活性状态的前体形式存在于血清中,约占血浆球蛋白总量的15％(W/W)。当因某种原因被激活时,补体各种成分便按一定顺序呈现连锁的酶促反应,参与机体的防御功能和维持自身稳定状态,也可作为一种介质或效应物参与机体的免疫病理过程。一、补体系统的组成: (一)补体系统的命名: 由于补体系统包括多种成分,以前命名较混乱,现按1968年WHO所规定予以介绍:C、代表
Complement system The complement system is a group of multi-molecular serum proteins present in fresh serum. Each component is normally present in the serum as an inactive precursor, approximately 15% of the total plasma globulin (W / W). When activated for some reason, various components of complement display a chain of enzymatic reactions in a certain order, participate in the body’s defensive function and maintain their own stable state, but also as a mediator or effector involved in the body’s immune pathology . First, the composition of the complement system: (A) the name of the complement system: Since the complement system includes a variety of components, the former name more chaotic, according to the provisions of the 1968 WHO to be introduced: C, on behalf of
