摘要: Guinea pig and rat sciatic nerves were fixed with cacodylate-buffered aldehydes OsO4, stained ferric ion ferrocyanide. Cytoplasmic surfaces of the non-myelinated nodal axon membrane A-fibres display distinct electron-dense aggregates stain. These not observed in association paranodal or internodal axolemma. The membranes C-fibres exhibit no staining under these conditions. Thus, axolemma normal myelinated fibres is structurally from both membrane, C-fibres. ion-ferrocyanide technique may provide a method for marking axonal properties.
