Abstract:
:Alterations of nodal and paranodal axolemma of the rat sciatic nerve were investigated in antigalactocerebroside serum-induced demyelination. A ferric ion-ferrocyanide (FeFCN) stain that appears to stain the regions with a high sodium channel density in nerve fibers was applied. When acute conduction block was initiated 20 to 180 minutes after the antiserum injection, myelin terminal loops began to be detached from the paranodal axolemma and reaction product of FeFCN stain originally localized at the nodes decreased in density and extended to the paranodal axolemma. By the time that complete conduction block was established, 5 hours after the injection, FeFCN stain was barely detectable around the nodal area. The loss of staining was associated with detachment and vesiculovacuolar degeneration of the paranodal myelin. This rapid deterioration and disappearance of normal cytochemical characteristics of the axolemma in the presence of only modest paranodal demyelination could be a morphological correlate of the loss of excitability of the axon membrane.
