摘要: 对SARS死亡患者的尸检标本进行了光镜和电镜观察。结果:SARS病原体引起人体多个脏器的超微结构发生病理变化,表现为肺泡壁增厚,肺泡腔有絮状渗出物、间质可见纤维素及少量炎细胞浸润;心肌纤维断裂,线粒体肿胀;脾和淋巴结细胞膜崩解破坏;肾小管上皮细胞坏死脱落。在病变组织中可见少量病原颗粒。提示:SARS病原引起人体的细胞免疫病理反应,引起机体多个脏器,特别是肺、心及免疫器官的损害。

Abstract: To investigate the relationship between the clinical expression and ultrastructural pathology of internal organs in SARS. The autopsy specimens included lungs(8 cases) , hearts(4 cases), livers(4 cases), spleens(3 cases), kidneys(5 cases) and lymph nodes(3 cases) obtained from SARS cases. These organ samples were examined with light and electron microscope. The examination result shows: the wall of alveolus becames thicker; some of the inflammatory cells and fibrin seeped to the alveolar sac as well as lung interstitial; the fibril of cardiac muscle broke and mitochondria swelled; the lymph cells necrosis and membrane were destroyed in the spleen and lymph node. Some pathogen particles were observed in certain organs under the electron microscope. The SARS pathogen as a causative factor of the disease causes the immunopathological reaction. This reaction leads to the damage of the human body, especially to the damage of the lung, heart and immunity organs.

Key words: SARS, organs, pathology, ultrastructure
