本文应用胶体碳作为示踪物,对小鼠在大肠杆菌内毒素引起休克时的肺、小肠和膈肌进行子血管通透性的形态学研究。 结果表明,注射大肠杆菌内毒素后30分钟,属于体环循系统的支气管微静脉,小肠粘膜下层中之微静脉以及膈肌血管树的微静脉和毛细血管后微静脉段开始标记有碳黑颗粒。这些标记有碳黑颗粒的微静脉,在电镜下发现内皮间的连结已打开(即相邻内皮细胞膜之间的间隙加宽了),碳黑颗粒通过这些已打开的连
In this paper, colloidal carbon was used as a tracer to study the morphology of mice vascular permeability of the lung, small intestine and diaphragm muscle during endotoxin-induced shock in E. coli. The results showed that 30 minutes after the injection of E. coli endotoxin, the bronchial microvessels belonging to the systemic circulation system, the microvessels in the small intestinal submucosa, and the venules of the vascular tree of the diaphragm and the microvessel behind the capillaries began to be labeled with carbon black particles. These veins, labeled with carbon black particles, revealed under electron microscopy that the link between the endothelium was opened (ie, the gap between adjacent endothelial cell membranes widened) through which carbon black particles passed
