Higher number of healthy axons and less number of degenerated axons were detected in treated groups. A. Naïve; B. T3; C. Sob; D. Sob-AM2; E. vehicle Red asterisk shows decompacted myelin, # axon with debris and triangle shows degenerated axon. F. quantitation of myelinated axons G. quantitation of degenerated axons. p value <0.0009****, < 0.005***, and <0.02**. The graphs include data from vehicle n=17, T3 n=16, Sob n=14 Sob-AM2 n=18 and naïve n=8. Scale bar 2 μm.
