Images of regenerative nerves in transverse section after ES treatment applied at different timing in diabetic rats from (A) group A (PID 1), (B) group B (PID 8), (C) group C (PID 15), (D) group D (no ES), and in nondiabetic normal rats from (E) group E (no ES).
Nerves show the typical aspect of a regenerated nerve, with myelinated axons (MA), Schwann cells (SC) and blood vessels (BV), which tended to disperse in the endoneurium. (F) Comparisons of cross-sectional area and (G) axon numbers (*p<0.05 compared to nondiabetic normal group, #p<0.05 compared to diabetic control group, $p<0.05 compared to group C, &p<0.05 compared to group B, ^p<0.05 compared to group A). Each data represents the mean ± standard deviation. Bar = 20µm.
