摘要

背景：腮腺和下頜下腺為3大唾液腺體中的兩對，雖知其交感神經的來源為上頸神經節，但是在這些交感神經進入此2腺體的分佈情況，則仍待探索。
方法：本研究以人類下頜下腺及腮腺切除的標本，應用甘草酸與兒茶胺形成之組織螢光法（glyoxylic catecholaminergic histofluorescence method），並採用1%中性紅（neutral red）作對照染色，探討2大唾液腺的交感神經分佈。
結果：發現大部份交感神經分佈於腺體區及血管周圍，在包膜或腺體間的結締組織亦可發現少許的交感神經纖維；至於各種大小的腺管則無。
結論：若交感神經可影響腺體分泌，可能經由直接控制腺體來作用，至於腺管缺乏交感神經支配，應不受交感神經直接的影響。

Background: The parotid and submandibular glands are two of the three major salivary glands. Although the postganglionic sympathetic fibers are know to be from the superior cervical ganglion, the distribution of the sympathetic fibers in these glands still needs additional study.
Materials and methods: Postoperative specimens from human parotid and submandibular glands were used. The glyoxylic catecholaminergic histofluores-cence method was employed on the tissues to study the sympathetic innerve-tion. One percent neutral red was used as a counterstain.
Results: Most sympathetic fibers were found around the glandular area and adventitial layers of vessels, and a few were found in the capsule or interglan-dular connective tissues. The ducts lacked sympathetic innervation.
Conclusion: Sympathetic innervation may have a direct control on the glandular secretions of these two major salivary glands. Because the secretory ducts lack sympathetic innervation, the sympathetic nerves may not directly affect the ducts.
