Figure 5.
Effects of electric stimulation and decimeter wave on ultrastructure of the sciatic nerves in rats with sciatic nerve compression at the 2nd week post-operation (transmission electron microscopy, × 15 000).
The cellular membrane of myelin sheath epineurium was detached from the axon, the myelin sheath was unevenly swollen, and the mitochondria appeared vacuolar necrotic and disintegrated in the control group (A). A novel axon bud, which was encapsulated by the epineurium, was present in the proximal end of the entrapped segment in the intraoperative electric stimulation and decimeter wave group (B).
