肺结节病是以活化的T淋巴细胞及单核吞噬细胞为主组成的肉芽肿及以肺泡炎为特征的细胞免疫性疾病。已知本病活动程度与肺内T淋巴细胞的数目、类型及功能有明显的关系。本文进一步阐明肺单核吞噬细胞在肺结节病发病机理中的作用。未治疗的肺结节病14例;按支气管肺泡细胞中T淋巴细胞数分为2组,>28％,~(67)镓扫描阳性为高度
Pulmonary sarcoidosis is a granulomatous granuloma mainly composed of activated T lymphocytes and mononuclear phagocytes and a cellular autoimmune disease characterized by alveolitis. It is known that the degree of activity of the disease and the number of T lymphocytes in the lung, type and function of a clear relationship. This article further elucidates the role of pulmonary mononuclear phagocytes in the pathogenesis of pulmonary sarcoidosis. Untreated pulmonary sarcoidosis in 14 cases; according to the number of bronchial alveolar cells in T lymphocytes divided into two groups,> 28%, ~ (67) gallium-positive scan for the height
