血小板凝集所形成之微栓子(micro-emboli)所致的微血管系统堵塞可于休克时大量发现。且以之可解释实验性休克时所常见的病理改变。为了进一步了解微栓子在不可逆性休克发生上可能具有的重要意义,作者应用电影显微摄影技术(Cinephotomicrographic technic)来观察及研究家兔因出血、创伤、过敏、内毒素及细菌所致之实验性休克时之微血管动力变化。作者将投射直径放大50,000—100,000倍后发现,于实验兔之肠、肠系膜、肝脏及肺脏等微血管系统中均具血小板凝集而成之微栓子形成。此种微栓子可引起其狭窄部分之机械性阻塞,直径10—40微米之血管为之临界血管(Critical-vessel)。
The microvascular occlusion caused by micro-emboli formed by platelet aggregation can be found in large quantities in shock. And to explain the common pathological changes in experimental shock. In order to further understand the importance of micro-emboli in the development of irreversible shock, the authors used Cinephotomicrographic technic to observe and study the experiments of rabbits caused by bleeding, trauma, allergy, endotoxin and bacteria Microvascular changes during sexual shock. The author enlarged the projected diameter of 50,000-100,000 times and found that in the rabbit intestine, mesentery, liver and lung microvascular system with platelet aggregation of micro-emboli formed. Such micro-emboli can cause mechanical obstruction of its narrow parts, the diameter of 10-40 micron blood vessels for the critical-vessel.
