Preliminary results on the localization of substance P-like immunoreactivity in the human cerebellum are presented. Cerebella from newborn and adult subjects were examined. While only sporadic positive fibres were detected in the adult tissue, the immunoreactive material appeared more abundant in the cerebella from newborn subjects. Varicose and non-varicose fibres and dot-like nerve terminals were present with different density in various regions. The paucity of immunoreactive perikarya suggests that most of the cerebellar substance P-like immunoreactive material has an extrinsic origin.
本文展示了关于人小脑内P物质样免疫反应性定位的初步结果。研究检查了来自新生儿和成人受试者的小脑。在成人组织中仅检测到散在的阳性纤维,而在新生儿受试者的小脑中,免疫反应性物质似乎更为丰富。曲张和非曲张纤维以及点状神经末梢在不同区域以不同密度存在。免疫反应性核周体的稀少表明,小脑内大多数P物质样免疫反应性物质来源于外部。
