Figure 4.

The effect of ketone salt combined with the ketogenic diet on white matter sparing in spinal cord injury rats 8 weeks post injury.

Representative images of eriochrome cyanine-stained spinal cord sections (A) and quantification of spared white matter at various distances rostral-caudal from the lesion epicentre (B) 8 weeks post-injury for the KD + KS + SCI (black; n = 15) and SCI groups (gray; n = 17). The spared myelin area was not larger in the KD + KS + SCI group than in the control group. No significant differences were found. Bar scale: 500 μm. Data are expressed as the mean ± SEM (n = 5 per group), and were analyzed using two-tailed unpaired Student’s t-tests.
