Figure 3: Effect of EA stimulation on cytokine mRNA expressions in the DRG. (a) Representative photographs of cytokine expressions in the DRG. (b) Expression levels of IL-1 and IL-6 in the DRG of neuropathic rats were significantly higher than those in naïve rats. However, the expression level of TNF-α was not significantly higher than in naïve rats. After EA stimulation, IL-1 cytokine expression level was significantly decreased. NP: neuropathic group; NP+EA: neuropathic with electroacupuncture group; Sham: sham-operated group; Naïve: normal group (* compared to naïve, compared to neuropathic rats).
