Figure 2: Effect of EA stimulation on cytokine mRNA expressions in injured nerves. (a) Representative photographs of cytokine expression in peripheral nerve tissue. (b) Expression levels of IL-1β, IL-6, and TNF-α in peripheral nerves of neuropathic rats were significantly higher than those in naïve rats. However, after EA stimulation, the cytokine expression levels were 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).
