Results the major morphologic changes were as follows : histologically , alveolar inflammation and interstitial fibrosis were observed . electron microscopic findings were : 1 . alveolar type i cells were degenerated 、 broken - down and desquamated , endothelial cells were swelled , with inter cellular tight junction shortened , alveolar type ii cells hyperplastic , basement membrane thinned and deformed ; 2 . alveolar macrophages and interstitial macrophages were hyperplastic ; 3 . mast cells were infiltrated and degranulated ; 4 . electron - dense deposits were present at alveolar wall ; 5 . myofibroblasts 、 fibroblasts 、 collagen and basement membrane like material were hyperplastic
电镜观察可见： ( 1 ) i型肺泡上皮细胞变性、崩解和脱落，内皮细胞肿胀，细胞间紧密连接短小， ii型肺泡上皮细胞增生，基底膜变薄和破坏； ( 2 )肺泡巨噬细胞、间质巨噬细胞增多； ( 3 )肥大细胞浸润并见脱颗粒现象； ( 4 )肺泡壁电子致密物沉积； ( 5 )肌纤维母细胞、纤维母细胞、胶原原纤维及基底膜样物质增生。
