Total numbers of activated NF-κB positive cells in spinal cord of rats at different time post-injury. All bars represent mean values and error bars represent standard deviation. There were significantly increased activated NF-κB positive cells in experiment and experiment control group in comparison to sham surgery group (p<0.05) and significant decrease in experiment group in comparison to experimental control group (p<0.05). ^*Re-presents the time point of highest and significant difference in expression of NF-κB post-injury. NF-κB : nuclear factor-κB.
