Table 1

Morphometric measurements in different groups 12 weeks after surgery.

Group	Fiber diameter (μm)	Axon diameter (μm)	Myelin thickness (μm)
Normal group	8.20 ± 1.82	3.60 ± 0.88	2.30 ± 0.70
Model group	3.75 ± 0.85*	1.75 ± 0.64*	1.00 ± 0.28*
Treatment group	5.35 ± 0.88^*▲	2.95 ± 0.60^*▲	1.20 ± 0.25*

∗P < 0.05 versus normal group; ^▲P < 0.05 versus model group.
