Effect of GSNO on CEC-induced degeneration of myelin (Fig 4A) and g-ratio of CE fibers (Fig 4B). CE fibers 7week after CEC were processed and analyzed with EM. g-ratio was calculated with axons of 2nm thickness. CE of Vehicle animals showed remarkable degeneration of myelin (A;arrow). The myelin pattern of CE fibers of GSNO animals was similar to that of sham animals. The Schwann-like cell morphology and its relationship to the nerve fiber were comparable in sham and GSNO groups (arrow head). Electron micrographs are representative of n= 4 in each group. g-ratio of axons of vehicle was significantly higher than sham and GSNO animals, indicating decreased level of myelin. * p>0.05 vs. sham and GSNO.
