Figure 6.

The effect of quercetin-loaded zein-based nanofibers on axonal density. (a) Images showing sections of the lesioned nerve stained with toluidine blue at 100x magnification. (b) Bar graph showing the density of axons in the lesioned nerve in various treatment groups. Values are given as mean ± SEM (n = 8/group). ^∗∗∗p < 0.001, compared to diabetes mellitus (DM) + crush injury and no treatment. ^##p < 0.05 and ^###p < 0.001, respectively, compared to DM + crush injury + zein-based nanofiber.
