  • Abstract
  • Look Inside

Sural nerves from sixteen cases with various neuropathies were examined by fiber teasing method. Five of them showed normal findings, another five nerves could not be teased, because of their very strong demyelination in almost all fibers. They showed, however, almost intact axons with histological examination. Other seven cases revealed various features of myelin sheath changes of axonal degeneration type, or of segmen-tal demyelination, paranodal demyelination and remyelination. Some teased nerves revealed distinct alteration in about half of fibers, although usual histological observation showed only slight changes, that is, teasing method is very sensitive to catch the early changes of nerves.

Various features of segmental demyelination, including that of metachromatic leukodystrophy, peroneal muscular atrophy, paraproteinemia were demonstrated. The relationship between segmental demyelination, axonal demyelination and the onion-bulb formation was discussed.
