The presence of substance P- and enkephalin-like immunoreactive nerve fibers and terminals is demonstrated in the human paravertebral sympathetic ganglia by an indirect immunofluorescence technique. Substance P-positive nerve structures appear in the form of fiber bundles, isolated varicose filaments and dot-like and basket-like nerve terminals around the neuronal cell bodies. Their density shows a remarkable individual variability. Enkephalin-positive nerve structures appear as isolated varicose filaments and dot-like nerve terminals, forming densely innervated patchy areas. No substance P- or enkephalin-containing cell bodies were detected. No overlapping seems to exist among the areas innervated by the two types of neuropeptides.
采用间接免疫荧光技术在人椎旁交感神经节中证实了P物质和脑啡肽样免疫反应性神经纤维及终末的存在。P物质阳性神经结构呈纤维束、孤立的曲张细丝以及神经元胞体周围的点状和篮状神经终末的形式。它们的密度显示出显著的个体差异。脑啡肽阳性神经结构表现为孤立的曲张细丝和点状神经终末，形成密集支配的斑片状区域。未检测到含P物质或脑啡肽的细胞体。两种神经肽支配的区域之间似乎不存在重叠。
