Relative mRNA levels of inflammatory mediators in DRG tissues

Gene	CFA	Saline + CFA	EM-1 + CFA	EM-2 + CFA
IL-1β	2.46 ± 0.70	3.67 ± 0.61*	1.08 ± 0.16 #	2.33 ± 0.57
IL-10	0.33 ± 0.11**	0.51 ± 0.13*	0.80 ± 0.12	0.77 ± 0.23
TNF-α	2.84 ± 0.41*	2.07 ± 0.60	1.41 ± 0.51	1.21 ± 0.08
CCL2	2.51 ± 0.63	2.91 ± 0.38*	1.25 ± 0.37	1.97 ± 0.61
CCL3	2.20 ± 0.44**	3.03 ± 0.34**	1.21 ± 0.35	2.58 ± 0.63

Inflammatory mediators mRNA levels are assessed by RT-PCR assay and normalized to GAPDH-expression

^*P < 0.05 and ^**P < 0.01 indicates significant differences compared with Control samples according to one-way ANOVA followed by Bonferroni post-hoc analysis

^#P < 0.05 indicates significant differences compared with Saline + CFA samples according to one-way ANOVA followed by Bonferroni post-hoc analysis
