用抗5-羟色胺抗血清免疫过氧化物酶方法，观察了5-羟色胺免疫反应细胞在鸡颈动脉体区的分布。鸡的甲状旁腺、甲状旁腺、颈动脉体部和多鳃部腺沿颈总动脉呈连续分布，由动脉发出的分支供血。雏鸡颈动脉体主细胞几乎全部呈5-羟色胺免疫反应阳性。此外，许多5-羟色胺免疫反应细胞广泛分布于颈总动脉发出的供应各内分泌器官的动脉周围的外膜结缔组织中，即颈动脉体动脉、食管气管动脉、食道升动脉和甲状腺下动脉。这些动脉通常由一条主干从颈总动脉中部的外侧发出。5-羟色胺细胞在颈动脉体部周围最多，分布于颈动脉全长。此外，在每条动脉的共同主干和食道上升动脉、甲状腺下动脉和食道气管、支气管动脉的根部周围也检测到了它们。5-羟色胺细胞也分布于颈总动脉中膜。在该部位，它们集中在各动脉共同主干的起始点附近，沿起始点纵轴散布在起始点下方，在起始点的对侧。分布在动脉周围和动脉内的5-羟色胺免疫反应细胞可能参与血流的控制，并可能具有趋化作用。
By using an immunoperoxidase method with antiserotonin antiserum, the distribution of serotonin‐immunoreactive cells in the carotid body region was investigated in chickens. The thyroid gland, cranial and caudal parathyroid glands, carotid body, and ultimobranchial gland of chickens were located along the common carotid artery as a continuous series and were supplied with branches arising from the artery. Almost all chief cells of the chick carotid bodies were immunoreactive for serotonin. Furthermore, numerous serotonin‐immunoreactive cells were widely distributed in the adventitial connective tissue around those arteries that issued from the common carotid artery to supply each endocrine organ, i.e., the carotid body artery, the esophagotracheobronchial artery, the ascending esophageal artery, and the inferior thyroid artery. These arteries usually arose by one trunk from the lateral aspect of the middle portion of the common carotid artery. The serotonin cells were most numerous around the carotid body artery and were dispersed along the whole length of the artery. In addition, they were detected around the common trunk of each artery and the roots of the ascending esophageal artery, the inferior thyroid artery, and the esophagotracheobronchial artery. The serotonin cells were also distributed in the tunica media of the common carotid artery. In that place, they were concentrated around the origin of the common trunk of each artery and were scattered below the origin along the longitudinal axis and on the opposite side of the origin. The serotonin‐immunoreactive cells distributed around and in the arteries may be involved in the control of blood flow and may have chemoreceptive properties.
