Alveoli form clusters ( alveolar sacs) connected by alveolar ducts to the Bronchioles. 肺泡形成丛集的肺泡囊,经由肺泡管连接至支气管。
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. 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] Both the alveolar sacs and alveolar spaces were enlarged in the senile group. 结果老年组大鼠肺泡囊扩张、肺泡腔轻度扩大。
