(B) There was a significant increase in the IL-8 concentration in the SSC at d1 but no difference at d3, d5, and d7 after CFA injection compared with saline injection (n = 6 in each time point). (C) There was a significant increase in the IL-8 concentration in the dorsal horn of lumbar spinal cord at d1, d3, d5, and d7 after CFA injection compared with saline injection (n = 6 in each time point). ** P < 0.01 compared with saline controls.
