Substance P-immunoreactive neurons were demonstrated in chick embryonic and adult trigeminal ganglion and jugular-superior ganglionic complex using FITC-immunohistochemical methods. Both small-size and large ganglion cells exhibited SP immunoreactivity, without apparent changes during embryonic and post-hatching development. SP-positive fibers could be detected in a good number in the sympathetic cranial cervical ganglion, either during embryonic development or in adult chick. No immunoreactive perikarya were observed in this ganglion. In the ciliary ganglion, both choroidal and ciliary neurons were SP-negative, whereas SP immunoreactive fibers surrounded the perikarya of both cell populations.
采用异硫氰酸荧光素免疫组织化学方法，在鸡胚和成年鸡的三叉神经节以及颈静脉-上神经节复合体中证实了P物质免疫反应性神经元。小型和大型神经节细胞均表现出P物质免疫反应性，在胚胎期和孵化后发育过程中无明显变化。在胚胎发育期间或成年鸡中，均可在交感神经颈上神经节中检测到大量P物质阳性纤维。在该神经节中未观察到免疫反应性核周体。在睫状神经节中，脉络膜和睫状神经元均为P物质阴性，而P物质免疫反应性纤维围绕着这两种细胞群体的核周体。
