The differences in the number of degenerated axons between the normal and non plegic groups were not statistically significant (p < 0.05). In contrast, the differences between the non-plegic and plegic groups were significant (p < 0.005), but the differences between the normal and plegic groups were most significant (p < 0.0001). As for the endothelial cells of ANs, the difference between the normal and nonplegic side was not significant (p < 0.5), and the difference between the plegic and nonplegic side was significant (p < 0.005). The differences between the plegic side and normal groups, however, were most significant (p < 0.0001).
