Aim This study was done to investigate whether SPP has inhibitory effects on the activation of RAW 264.7 cells. Method In tumor necrosis factor-a (TNF-a)/ interleukin-1b (IL-1b) and IL-6, the mRNA expression of molecular indicators related to inflammatory changes of the Reumatoid Arthritis (RA) were examined using quantitative real-time PCR. Results The treatment of SPP significantly suppressed the expression of proinflammatory cytokines and chemokines such as TNF-a, IL-1b, IL-6 compared with the control. The expression of NOS-II was considerably reduced, which was accompanied by a reduction in the production of nitric oxide (NO). It also reduced the expression of in serum of Balb/c mice compared with control group. Conclusion SPP is an effective herbal material for suppressing the inflammation related cytokines of RAW 264.7 cells.
