Axon membrane remodeling in the lead-induced demyelinating neuropathy of the rat.

Single-teased fibers stained with the ferric ion-ferrocyanide method allowed us to study axonal remodeling in the lead-induced demyelinating neuropathy of the rat. Our findings, in agreement with recent physiological data, pointed to a transitory reorganization of the demyelinated axons to maintain impulse conduction until remyelination and formation of new cytochemically normal nodes had restored a secure saltatory conduction.
