The localization of vasoactive intestinal polypeptide (VIP)-immunoreactive (ir) nerve cell bodies and fibers has been studied in the gill arches of goldfish (Carassius auratus, L.) using the peroxidase-antiperoxidase (PAP) immunohistochemical method. It was found that VIP-ir nerve cell bodies are localized in connective tissue on the oral side of the gill arch; these cells were present as single cells, in couples or as small clusters. Moreover, a dense network of VIP-ir fibers was observed beneath the lining epithelium of the raker cushion. The possible involvement of this peptide in mucus secretion in the gill arches of teleost is discussed.
采用过氧化物酶-抗过氧化物酶（PAP）免疫组织化学方法，研究了金鱼（Carassius auratus, L.）鳃弓中血管活性肠肽（VIP）免疫反应性（ir）神经细胞体和纤维的定位。结果发现，VIP-ir神经细胞体位于鳃弓口腔侧的结缔组织中；这些细胞以单个细胞、成对或小簇的形式存在。此外，在鳃耙垫的内衬上皮下方观察到密集的VIP-ir纤维网络。本文讨论了该肽在硬骨鱼鳃弓黏液分泌中可能的作用。
