Protective Effect of Hyperbaric Oxygen Treatment on Axon Degeneration after Acute Motor Axonal Neuropathy

Figure 2

Hematoxylin and eosin-stained histopathological images at the cross section of the lumbar spinal cord. Microscopic views under 200× magnification show normal white matter at the control group (a), moderate axonal degeneration at the AMAN group (b), and mild axonal degeneration at AMAN with the HBO group (c). (Bold line arrows indicate neuronal edema. Thin line arrows indicate macrophage infiltration. Dotted line arrows indicate lymphocytic infiltration.) The scale bars represent 100 μm.
