用免疫组织化学方法对猫颈胸交感神经节石蜡切片进行甘丙肽样免疫反应性（甘丙肽-LI）的研究。甘丙肽-LI在节后神经元中观察到，其通过相邻切片的调查显示，也显示神经肽Y（NPY）-LI。其他神经肽Y阳性神经节细胞缺乏甘丙肽阳性。甘丙肽LI与血管活性肠肽LI在神经元内不共存。Galanin-LI神经纤维和副神经节细胞数量较少。这些发现表明甘丙肽可能参与交感神经对器官功能的控制。
Paraffin sections of feline cervicothoracic sympathetic ganglia were investigated for galanin-like immunoreactivity (galanin-LI) by means of immunohistochemistry. Galanin-LI was observed in postganglionic neurones, which, as revealed by investigation of adjacent sections, also displayed neuropeptide Y (NPY)-LI. Additional NPY-LI ganglion cells were devoid of galanin-LI. Galanin-LI did not coexist with vasoactive intestinal polypeptide-LI in neurones. Galanin-LI nerve fibres and paraganglionic cells were few in number. The findings suggest that galanin may participate in sympathetic control of organ function.
