高原肺水肿已有不少的临床资料报道,但有关高原肺水肿的肺泡超微结构方面的文献尚少。为此,本实验主要应用电镜和硝酸镧示踪电镜术,对模拟6,000米高原缺氧48h时大鼠肺泡超微结构进行了观察,以期为高原肺水肿的发病机制提供形态学基础资料。结果表明,缺氧48h后可引起肺泡结构改变:(1)光镜下肺泡隔增 High altitude pulmonary edema has been a lot of clinical data reported, but the alveolar ultrastructure of pulmonary edema literature is still low. To this end, the main application of electron microscopy and lanthanum nitrate tracer electron microscopy, simulated 6,000 m altitude hypoxia 48h alveolar ultrastructure was observed in order to provide the basis for the pathogenesis of high altitude pulmonary edema Morphological data. The results showed that hypoxia 48h after alveolar structure changes can cause: (1) light microscopic alveolar septum
