KRGE regulates the mRNA levels of inflammatory mediators in the spinal cord of EAE rats. (A–F) Real-time polymerase chain reaction results for mRNA levels of IL-6 (A), IFN-γ (B), COX-2 (C), IGF-β1 (D), TGF-β (E), and VEGF-1 (F) the spinal cord of EAE rats. Analysis of variance test; #p < 0.01 versus sham group; *p < 0.01 versus EAE group. COX, cyclo-oxygenase; EAE, experimental autoimmune encephalomyelitis; IFN, interferon; IGF, insulin-like growth factor; IL, interleukin; KRGE, Korean Red Ginseng extract; TGF, transforming growth factor; VEGF, vascular endothelial growth factor.
