神经肽Y免疫反应神经和细胞在大鼠颌下腺的分布

DISTRIBUTION OF NPY IMMUNOREACTIVE NERVES AND CELLS IN THE SUBMANDIBULAR GLAND OF RAT

本研究应用免疫组织化学ＡＢＣ技术，观察了含神经肽Ｙ神经和细胞在大鼠颌下腺内的分布特点。结果显示：含神经肽Ｙ神经纤维主要走行于腺泡、导管及血管周围。颌下腺内神经节细胞和颗粒曲管细胞亦呈神经肽Ｙ免疫反应阳性。提示：大鼠颌下腺的腺体分泌和血液供应可能受神经肽Ｙ能神经调控。

In this study, distribution of NPY immunoreactive nerves and cells in the submandibular gland of rat was observed by using the immunohistochemical ABC method. The NPY-containing nerve fibers were mainly localized around acini, ducts and blood vessels. The NPY-IR positive ganglion cells and GCT cells were observed. It suggests that NPY may be involved in the nervous regulation of acini secretion and blood supply in the submandibular gland.
