Fig. 4. Se@SiO2 enhanced axonal regeneration and BBB scoring. (a)–(c) represent NF200 positive axons in the sham, SCI and Se@SiO2 groups 28 d after SCI (400×). (d) shows the quantitative data for NF200 positive axons. (e) shows the BBB scoring after SCI. Data are expressed as mean ± SD. *P < 0.05 vs. sham group, #P < 0.05 vs. SCI group (n = 5).
