肺泡管

缺氧对支气管、肺泡管和肺泡囊上皮细胞NOS的活性无明显影响。

However , the NOS activities in epithelial cells of bronchi , alveolar duct and sac , in hypoxic rats were not affected .

脊髓前脚运动神经元和中央管室管膜细胞、肺内小支气管至肺泡管上皮及肺泡Ⅱ型细胞HCY2均高表达；

The expression of HCY-2 in motor neurons of anterior crus in spinal cord was fierce . Simultaneously HCY-2 fiercely expressed in epithelium from small bronchial to alveolar duct and type ⅱ alveolar cells .

结果：组织学上显示，对照组大鼠呼吸道包括支气管、细支气管、终末细支气管、肺泡管的上皮细胞和血管内皮细胞NOS表达均阳性，肺泡上皮细胞NOS表达阴性；

RESULTS : Histochemically , in normal rats , the NOS positive staining was found in epithelial cells of respiratory duct including bronchi , alveolar duct as well as in endothelium of pulmonary vessels , and the negative staining was found in pneumonocytes .

结果：糖尿病4周大鼠肺支气管上皮细胞、肺泡管上皮细胞、肺泡囊上皮细胞和动脉内皮细胞iNOS呈阳性或弱阳性，静脉内皮细胞、毛细血管内皮细胞iNOS呈阴性。

RESULTS : In diabetic rats , the iNOS positive or weak positive staining was localized in epithelial cells of bronchi , epithelial cells of alveolar ducts , alveolar sacs , and arteries , but negative in endothelial cells of vein and capillary .

肺微血管构筑可区分出呼吸性细支气管范围、肺泡管范围，以及肺泡范围3级微血管单位。

According to the microvascular architecture , the pulmonary microvasculature may be divided into three ordered units : i. e. the alveolar , the alveolar duct , and the respiratory bronchiolar units .

随胎龄增加，叶支气管、小支气管、细支气管、终末细支气管、呼吸性细支气管和肺泡导管管壁的粘膜上皮间均可见阳性细胞。

With the development , these cells could be seen in the epithelium of bronchi , bronchioles and alveolar ducts .

肺泡或肺泡管上皮表面有透明膜形成。

There was accumulation of neutrophils in the pulmonary capillaries and hyaline membrane formation on the epithelial surface of the alveoli and alveolar duct walls .

大部分肺泡腔及肺泡管内透明膜形成。间质有较多的炎细胞浸润，成纤维细胞增生。

Intensive inflammatory cell infiltration and fibroblast hyperplasia were presented .

肺泡形成丛集的肺泡囊，经由肺泡管连接至支气管。

Alveoli form clusters ( alveolar sacs ) connected by alveolar ducts to the Bronchioles .

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。

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 .
