Vascular hyperpermeability is one of the important causein hypovole-mia and organs disfunction after various kinds of shock,and its treatment is still one of the problems in the medical field. For example,the operative methods of preventing hyperpermeability and plasm bleeding is still unreliable after severity burn,and traditional treatment just passively transfuses according to the burn clysis formula instead of inhibiting permeability by injecting drugs. The principal reason is that pathogenesis of vascular endothelial cell permeabilty has not been entirely revealed at the level of molecular biology.

血管通透性增高是休克时有效血容量减少和器官功能损害的重要原因之一，它的防治一直是医学界的一个难题，如在大面积烧伤时，至今未能找到一个简单有效的防治血管通透性升高和血浆渗出丢失的方法，传统的方法只是根据烧伤补液公式测算进行被动的补液来纠正，而不能依靠注射化学制剂来终止其渗出，主要原因是未能从分子生物学水平揭示血管内皮细胞渗出的机制。
