用高分子右旋糖酐(MW.10万)静脉注射的方法复制大鼠循环血中出现微血栓的微循环障碍模型,用微循环电视显微镜观察微血栓的形态与结构,分析微血栓与心电图变化的关系。结果发现微血栓与ST段的变化间呈正相关，对其意义作了简单讨论。 The microcirculatory disturbance model of microthrombosis in the circulating blood of rats was duplicated by intravenous injection of polymer dextran (MW.100,000). The morphology and structure of microthrombus were observed by microcirculation video microscopy, and the relationship between microthrombus and electrocardiogram changes was analyzed. . The results showed that there was a positive correlation between microthrombi and ST segment changes, and its significance was briefly discussed.
