中文摘要 | 交感神經摘除後,曾有報告指出會導致相關周邊器官胜 性神經纖維免疫組織化學反應的密度增加。而三叉神經節共同受到感覺性胜 及自律性兒茶酚胺類神經的支配,因此自律性神經系統及一般感覺神經系統間可能存在著某些功能上的交互作用,但仍缺乏直接之解剖證據。本實驗旨在利用山葵過氧化氫 (horseradish peroxidase, HRP)逆向輸送標示特性,多巴胺β-羥基 (dopamine β-hydroxylase, DBH)免疫螢光技術以及抑鈣素基因相關胜 (calcitonin gene related peptide, CGRP)免疫組織化學法等,探討三叉神經節中交感性傳入神經纖維之來源處。實驗發現於三叉神經節注入HRP後48小時,HRP標示神經元存在於同側頸上神經節吻部。單側摘除頸上神經節後,會導致同側三叉神經節中DBH顯著降低,然而CGRP在三叉神經節中以及尾段腦幹三叉神經脊髓核的中間部及尾部腹側區均呈現增加。以上結果顯示三叉神經節中的交感性傳入神經來自頸上神經節,本實驗結果將可作為自律神經系統調控一般感覺神經系統的明確解剖證據。 |
英文摘要 | Sympathectomy has been shown to result in an increased density of peptidergic fiber immunoreactivity in peripheral targets. Trigeminal ganglion is the targets of both autonomic and sensory innervating which contains peptidergic and sympathetic catecholaminergic fibers. This suggests that there might exist anatomical and functional interactions between sympathetic and sensory systems. In this study, we examined the origins of sympathetic innervation on trigeminal ganglion by HRP retrograde transport technique and further studies the sympathetic innervation by examination of immunoreactivities for dopamine β-hydroxylase (DBH) and calcitonin gene related peptide (CGRP) in bilateral trigeminal ganglia followed unilateral superior cervical ganalionectomy. HRP positive labeled neurons, which restrictedly located at rostral portion, were only found in the ipsilateral superior cervical ganglion (SCG). After unilateral SCG ganglionectomy, the ipsilateral trigeminal DBH immunostaining was dramatically decreased while CGRP immunostaining in the ipsilateral trigeminal ganglion was elevated in response to SCG ganglionectomy. In the lower medulla, CGRP immunostaining was increased in both interpolaris and caudal portion of ventral spinal trigeminal nucleus. The data demonstrate that trigeminal sympathetic innervation originated from ipsilateral SCG. These results may provide anatomical evidence of autonomic modulation on sensory system. |
