Pathology.& Interstitial emphysema is characterized by air dissecting within the interstitium of the lung, typically in the peribronchovascular sheaths, interlobular septa, and visceral pleura. 其特征为空气夹在肺间质内,典型的位于血管支气管周围的鞘内、小叶间隔内和脏层胸膜内。
Value of CT and high-resolution CT in evaluating the degree of pulmonary interstitial fibrosises and prognosis of pulmonary emphysema CT及高分辨率CT在判断肺气肿患者肺间质纤维化程度及预后中的价值
Chronic interstitial pneumonia, pulmonary emphysema were mani-fested; 慢性间质性肺炎、肺气肿;
In the course from 28~ 36 months after administration, dust foci, dust fiber foci, interstitial fibrosis in varying degrees and focal emphysema were observed in lungs, but typical silica-nodule and progressive massive fibrosis were not shown. 经28~36个月观察,肺内形成尘灶、尘纤维灶、不同程度间质纤维化及灶周气肿,没见到典型矽结节与进行性大块纤维化过程。
Light microscope ( HE): PQ group shows that focal pulmonary hemorrhage, alveolar wall thickening apparent, alveolar and interstitial pulmonary edema, inflammatory cell infiltration, and some sections can be seen focal atelectasis, emphysema. 光镜检查:PQ组可见肺灶性出血,肺泡壁明显增厚,肺泡和肺间质水肿,大量炎性细胞浸润,部分切片可见灶状肺不张,肺气肿。
