방사선 육종 차조기와 백출 복합추출물의 항관절염 효과

In this study, anti-arthritic effect of the mixed extract of radiation mutant Perilla frutescens var. crispa and Atractylodes macrophala koidz was investigated. Cell viability was determined by MTT assay in RAW 264.7 cells. The anti-inflammatory effect of mixed extracts was determined through measurement of the levels of reactive oxygen species (ROS) and nitric oxide (NO), release of inflammatory cytokines and expression of NF-κB, COX-2 and iNOS in LPS-induced RAW 264.7 cells after treatment of mixed extracts (5, 10, 25 ㎍/㎖). We showed that the mixed extracts was not toxic in the dose of 5, 10, 25 ug/ml, and significantly inhibited production of nitric oxide and ROS, cytokines including IL-1β, IL-6, TNF-α, and inflammatory proteins including NF-κB, COX-2 and iNOS in LPS-induced RAW 264.7 cells. Moreover, the mixed extract inhibited the type II collagen induced arthritis in DBA mice in the dose of 66.5 and 133mg/kg/day. Therefore, we suggest that mixed extract of radiation mutant Perilla frutescens var. crispa and Atractylodes macrophala koidz can be developed as a raw material for health functional food and therapeutics to treat the inflammatory arthritis.
