Figure 1

Rat neurological severity score in different groups. The bar graph shows that there were no statisticaldifferences in the NSS of rats among the normal, sham-operated control and SBI alone groups. The NSS of rats in the DBI alone and DBI with SBI group increased sharply compared with that of normal, sham-operated control and SBI alone groups. The NSS of rats in the DBI with SBI group also significantly increased compared with that in the DBI group. ^aP < 0.05 vs normal, sham-operated control and SBI alone groups. ^bP < 0.05 vs DBI alone group.
