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 .
