The present paper describes tyrosine hydroxylase-like immunoreactivity in the ciliary ganglion of monkey (Macaca fascicularis) and cat. Under the light microscope, in the monkey, about 7.6% of neurons were observed to be intensely stained, 27.7% moderately stained and 32.5% lightly stained. In the cat, 1.2% of neurons were intensely stained, 5.4% moderately stained and 10.1% lightly stained. Ultrastructurally, tyrosine hydroxylase-like immunoreactivity was observed in neuronal somata, dendritic profiles and axons in both monkey and cat. Tyrosine hydroxylase-like immunoreactive dendritic profiles were synaptically contacted by tyrosine hydroxylase-negative axon terminals. In the monkey, tyrosine hydroxylase-like immunoreactive fibres were observed to enter the ciliary ganglion via the nasociliary nerve. Such fibres were observed to course among neurons within the ganglion and emerge in the short ciliary nerves. In contrast, tyrosine hydroxylase-like immunoreactive fibres were only occasionally observed in the cat.
本文描述了猕猴（食蟹猴）和猫睫状神经节中的酪氨酸羟化酶样免疫反应性。在光学显微镜下，在猕猴中，观察到约7.6%的神经元被强烈染色，27.7%中度染色，32.5%轻度染色。在猫中，1.2%的神经元被强烈染色，5.4%中度染色，10.1%轻度染色。在超微结构上，在猕猴和猫的神经元胞体、树突轮廓和轴突中均观察到酪氨酸羟化酶样免疫反应性。酪氨酸羟化酶样免疫反应性树突轮廓与酪氨酸羟化酶阴性轴突终末形成突触联系。在猕猴中，观察到酪氨酸羟化酶样免疫反应性纤维通过鼻睫神经进入睫状神经节。观察到此类纤维在神经节内的神经元之间穿行，并在睫状短神经中出现。相比之下，在猫中仅偶尔观察到酪氨酸羟化酶样免疫反应性纤维。
