Both alpha-melanotropin and beta-endorphin were revealed by immunofluorescence microscopy studies within neurons and nerve fibers of the rat duodenum. An immunohistochemical staining for alpha-melanotropin was seen within neuronal cell bodies and nerve fibers bundles of the myenteric and submucous plexus. A beta-endorphin immunofluorescence was visualized within perikarya and nerve fibers of both the myenteric and submucous plexus. alpha-Melanotropin as well as beta-endorphin immunoreactivities were strictly localized to structures of the enteric nervous system. In crypts and epithelial cells only a non-specific staining was observed.
通过免疫荧光显微镜研究发现，α-促黑素和β-内啡肽存在于大鼠十二指肠的神经元和神经纤维中。在肌间神经丛和黏膜下神经丛的神经元细胞体和神经纤维束中可见α-促黑素的免疫组织化学染色。在肌间神经丛和黏膜下神经丛的核周体和神经纤维中均可见β-内啡肽免疫荧光。α-促黑素以及β-内啡肽免疫反应性严格定位于肠神经系统的结构中。在肠隐窝和上皮细胞中仅观察到非特异性染色。
