Response to therapy in demyelinating motor neuropathy.

abstract：:To investigate whether various myelin markers could detect pathological changes in myelination, the activity of 2'-3'-cyclic nucleotide 3'-phosphodiesterase (CNP) and the level of PO protein were compared in the peripheral nervous system (PNS) of the dystrophic mouse and chicken and their phenotypically normal sibling...
