摘　　要：目的　观察经颈上节至结状节传递心脏感觉信息的迷走神经传入通路。　方法　逆行追踪及逆行追踪结合免疫组织化学方法。　结果　HRP注射入颈上节后 ,逆行标记的一小团细胞恒定地出现在结状节上段 ,其数量较少且分布局限。将荧光金 (fluorogold ,FG)注射入颈上节后并结合免疫荧光组织化学染色 ,观察到结状节内约 18 5 %的SP阳性标记细胞同时呈阳性FG逆行标记。　结论　结合以往文献 ,研究结果提示 。Objective To examine the cardiac primary afferents passing through the superior cervical ganglion which the sensory neurons are located in the vagal ganglion. Methods Retrograde tracing transport combined with immunohistochemistry. Results After injecting the horseradish peroxidase(HRP) into the superior cervical ganglion in the rat, the small number of retrogradely labeled neurons consistently appeared in the upper local portion of the nodose ganglion. The same injecting of fluorogold(FG) followed by immunohistochemical staining with SP, it was found that the double\|labeled neurons with FG/SP were approximately 20% occupied the total population of the SP positive neurons in the nodose ganglion. Conclusions The present results, associated with previous reports, suggest that the pathway of the vagal afferent conveying cardiac pain information which contains SP pass through the superior cervical ganglion.\;[
