正常人体凝血、止血及血栓形成机制的研究进展迅速,为出血性疾病的诊断和治疗提供了不少新的方法和措施,现将上述有关问题作简要译述和介绍。正常凝血、止血及血栓形成机制机体正常止血,主要依靠血管壁、血小板及凝血因子与纤维蛋白溶解活性各自的完整性以及其间的相互作用与平衡。在血管受损后,立即引起微小动脉的收缩来控制出血,这一反应是通过自律神经系统刺激血管壁平滑肌来实现的。血小板在出血部位释放出肾上腺素、血清素及血栓素A_2,加强这一反应。断裂 The normal human body coagulation, hemostasis and thrombosis rapid progress of the research, for the diagnosis and treatment of hemorrhagic disease has provided many new methods and measures, the above-mentioned problems are briefly translated and introduced. Normal coagulation, hemostasis and thrombosis mechanisms The body is normally hemostatic, relying mainly on the integrity of the vascular wall, platelets, and clotting factors and fibrinolytic activity, as well as the interaction and balance between them. Immediately after the vessel has been damaged, the constriction of the tiny arteries can be controlled to control the bleeding. This response is achieved by the autonomic nervous system stimulating the vascular smooth muscle. Platelets release epinephrine, serotonin, and thromboxane A 2 at the site of bleeding to enhance this response. fracture
