Panacinar emphysema occurs with loss of all portions of the acinus from the respiratory bronchiole to the alveoli. 全腺泡型肺气肿发生时则出现从呼吸性细支气管到肺泡的腺泡所有部分全部扩张。
Results In 36 cases ( 88%) of study group, fibrosis proliferation could be seen in peri bronchial area, especially in the bronchi under grade ⅵ. Respiratory bronchiole and alveoli were also involved in 11 cases. 结果41例中36例(88%)支气管各级分支,特别是Ⅵ级以下的支气管周围出现了程度不等的纤维组织增生,其中有11个病例累及呼吸细支气管及肺泡壁。
The most apparent features of chronic bronchitis in coal miners include dust deposition and dust cell infiltration on the walls of bronchi at all levels, and dust fibrosis around the bronchial walls, with the most severe pathological change of dust deposition on the respiratory bronchiole. 煤矿工人慢性支气管炎最显著的特点是在各级支气管管壁有粉尘沉积和尘细胞浸润,支气管壁周围可有尘性纤维化,特别是在呼吸性细支气管处尘性病变最重。
The end of the respiratory bronchiole has a sphincter. 呼吸性细支气管末端有括约肌。
Respiratory region has a great number of alveolar ducts. There are 6 to 8 alveolar ducts in each of pneumatic bronchiole. Alveolus is rather small and semi-full. 呼吸部肺泡数多,每支呼吸性细支气管分出68支肺泡管,肺泡较小,处于半充容状态。
Morphological observations on dust-maculae-emphysema occurred on respiratory bronchiole and alveolar track in 86 autopsy cases of coal workers were performed. 对86例煤工尸检肺组织呼吸性细支气管及所属肺泡道发生的尘斑气肿进行了观察。
Pathologically, all layers of the respiratory bronchiole walls were involved. 病理形态特点是呼吸性细支气管全层受累。
The result showed a thick and dense distribution of bronchus and bronchiole of asthma group; a sparse distribution in respiratory bronchiole and pulmonary alveoli; some positive fibers extrude the epithelium mucosae into the alveoli. 结果发现哮喘组肺内支气管及细支气管阳性纤维增粗、分布密集度显著增加:在呼吸性细支气管及肺泡亦偶有分布;有部分阳性纤维经粘膜上皮内伸出并暴露于管腔内。
