ECSW therapy suppressed the inflammatory cell infiltration in sciatic nerve (n=10). A-C. Illustration of immunofluorescent microscopic (400x) finding of F4/80+ cells (yellow arrows) in sciatic nerve. D. Analytical result of number of F4/80+ cells, * vs. other group with different symbols, p<0.001. E-G. Illustration of imunohistochemical microscopic (400x) finding of CD14+ cells (red arrows) in sciatic nerve. H. Analytical result of number of CD14+ cells, * vs. other group with different symbols, p<0.001. The scale bars in right lower corner represent 20 µm. All statistical analyses using one-way ANOVA, followed by Bonferroni multiple comparison post hoc test. Symbols (*, †) indicate significance (at 0.05 level). AMC=aged matched control; DM=diabetes mellitus; SW=shock wave.
