The distribution patterns of aminergic and cholinergic nerve fibers in the feline spinal blood vessels were studied by means of amine histofluorescence and acetylcholinesterase (AChE) staining. The anterior spinal artery had a dense network of aminergic and AChE-positive (probably cholinergic) nerve fibers. The posterior spinal vein, in contrast, had only aminergic nerve fibers. Intraparenchymal small blood vessels in the spinal cord also had strongly fluorescent (probably peripheral) aminergic nerve fibers. This was quite a characteristic feature in the spinal cord. The distribution pattern and the density of these two sorts of nerve fibers widely varied with the individual segment of the spinal cord. The thoracic spinal cord had the lowest number of these nerve fibers throughout the spinal cord. This fact may give a clue to explain why the thoracic spinal cord is most susceptible to ischemic change.
通过胺类组织荧光法和乙酰胆碱酯酶（AChE）染色法，研究了猫脊髓血管中胺能和胆碱能神经纤维的分布模式。脊髓前动脉有密集的胺能和AChE阳性（可能是胆碱能）神经纤维网络。相比之下，脊髓后静脉只有胺能神经纤维。脊髓实质内的小血管也有强荧光（可能是外周的）胺能神经纤维。这是脊髓中一个相当典型的特征。这两种神经纤维的分布模式和密度在脊髓的各个节段有很大差异。在整个脊髓中，胸段脊髓的这些神经纤维数量最少。这一事实可能为解释为什么胸段脊髓最易发生缺血性改变提供线索。
