摘　　要：目的　对大鼠下颌下腺内神经型一氧化氮合酶 (nc NOS)及神经营养因子 (NT 3)进行定性和定位研究。方法　取 10只SD大鼠下颌下腺 ,进行HE染色和免疫组织化学染色。结果　大鼠下颌下腺颗粒曲管、纹状管及小叶间导管上皮细胞呈ncNOS及NT 3免疫反应阳性 ,而腺泡细胞则为阴性。结论　大鼠下颌下腺导管上皮中有ncNOS及NT 3的表达 ,提示下颌下腺具有复杂的分泌功能。Objective To study the localization and character of neuronal-constitutive nitric oxide synthase(ncNOS) and nerve neurotrophic factor 3(NT-3) in rat submandibular gland. Methods Submandibular glands from ten SD rats were used by hematoxylin-eosin and immunohistochemical staining. Results Granular convoluted tubule,striated duct and interlobular epithelia cells showed ncNOS and NT-3 immunoreactivity whereas the acinar cells were negative. Conclusion ncNOS and NT-3 was expressed in rat submandibular glands,suggesting complicated function of secretion in rat submandibular glands.
