Figure 7. Micrographs of the dorsal column.
Intact myelin appears blue in eriochrome cyanine-stained sections of the spinal cord. Spinal cord images from control, 7, 14, 21, and 28 dpi samples are shown in A-E, respectively. Oil red O-stained sections for control, 7, 14, 21, and 28 dpi samples are shown in F-J. Lipid appears red with darker droplets apparent in the lesion. Qualitatively, the number of dark droplets decreased over time. The lesion size decreased to less than half of its size at 7dpi, shown in the graph of fractional area of EC staining in the dorsal column (mean ± SEM) (K).
