Abstract

The filipin-sterol technique was employed, together with freeze-fracture, to investigate the fine structure of the unmyelinated nerve fibre in the peripheral nerve. No heterogeneity was observed in the distribution of filipin labelling either in the Schwann cell plasma membrane or along the axolemma. The distribution of labelling is contrasted with that in the myelinated nerve fibre and related to the relative morphology and electrophysiology of the two types of fibre.

摘要

采用菲律宾菌素-甾醇技术并结合冷冻蚀刻技术，研究外周神经中无髓神经纤维的精细结构。在施万细胞质膜或轴膜上，均未观察到菲律宾菌素标记分布的异质性。将标记分布与有髓神经纤维中的分布进行对比，并与两种纤维的相对形态和电生理相关联。
