The Effect of Homnis Placenta Herbal Acupuncture on Reducing Expression of LPS-induced Arthritis Model as an Anti-inflammatory Agent

자하차약침(紫何車藥針)의 항염증능(亢炎症能)이 LPS 유발 관절염(關節炎) 치료(治療)에 미치는 영향(影響)

Objectives : Rheumatoid arthritis(RA) is a systemic & a chronic inflammatory autoimmune disease . A chronic , locally destructive inflammmatory reaction in human is examplified by the synovitis present in some connective tissue disorder. The presence of a number of cytokines, $TNF-{\alpha}$, iNOS & expression of nitric oxide, NF-kB p65 activation implies an important role of cellular immune response in RA inflammatory reaction. This study was designed to evaluate on the effects of the Homnis Placenta herbal acupuncture on EX-LE201 & ST 35 reducing expression of LPS-induced arthritis model in mice. Materials and Methods : Homnis Placenta herbal acupuncture was inserted into 10 rats induced rheumatoid arthritis. The acupunctures were injected into the EX-LE201 and ST35 points. Such indexes were measured the inhibition of inducible nitric oxide synthase(iNOS) expression, nitric oxide(NO) production in vitro experiment and Tumor Necrosis $Factor-{\alpha}(TNF-{\alpha})$ & Nuclear Factor kappa $B(NF-{\kappa}B)$ p65 activation, synovial hyperplasia, angiogenesis and fibrosis in synovial membrane of knee joint of mice in vivo experiment. Results : 1.Homnis Placenta Herbal acupuncture inhibited iNOS mRNA and NO in RAW 264.7 cell of LPS-induced rheumatoid arthritis in a dose dependent manner. 2.Homnis Placenta Herbal acupuncture also showed significant inhibition of $TNF-{\alpha}$ & $NF-{\kappa}B$ p65, activation, synovial hyperplasia, angiogenesis and fibrosis in synovial membrane of knee joint of mice. Conclusion : These results suggest that Homnis Placenta Herbal acupuncture has an therapeutic effects on LPS induced-rheumatoid arthritis by inhibiting $TNF-{\alpha}$ activation.
