Chrysanthemum boreale Makino is widely distributed in Korea, China, Japan and Southeast Asian countries. C. boreale is one of the herbs used for treating various inflammatory diseases in oriental medicine. The present study was conducted to identify biologically active compounds from the leaves and stems of C. boreale. We isolated two sesquiterpene sactones from the leaves and stems of C. boreale using silica gel column chromatography and recyclic high perfomance liquid chromatography. The lactones were characterized by their spectroscopic data (NMR, IR, MASS). These compounds were subjected to Farnesyl Protein Transferase (FPTase) inhibition, Nitric Oxide (NO) release inhibition and apoptosis inhibition. The structur of the following isolated compound were elucidated 8,10-${\small{O}$-Acetyl-2-methoxy-10-hydroxy-3,11(13)-guaiadiene-12,6-olide and 4,10-dihydroxy-8-${\small{O}$-Acetyl-2,11(13)-guaiadiene-12,6-olide. In the NO release inhibition assay, compound 2 showed strong activities, with an $IC_{50}$ value of $7{\mu}g/mL$, whereas compound 1 did not exhibit significant activity with an $IC_{50}$ value of over $14{\mu}g/mL$ against murine macrophage.

Lactoferrin(Lf) has the function of modulation in the host defense systems, including cytokine production and immune responses. We have tested the effect of Lf and Lf ydrolysates(Lf-H) on the productions of tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) and nitric oxide(NO) in macrophage cells. Lf from Korean native cattle(K-Lf) and hydrolyzed K-Lf(K-Lf-H) increased the production of TNF-${\alpha}$ in RAW264.7 cells with dose-dependency. Bovine Lf(B-Lf), human Lf(H-Lf), and its hydrolysates did not induce either TNF-${\alpha}$ production or NO production. On the other hand those didn\`t affect on the production of TNF-${\alpha}$ in lipopolysaccharide(LPS)-stimulated RAW264.7 cells. K-Lf induced the production of NO similar to its role on the TNF-${\alpha}$ production.

Objectives : The purpose of this study is to prove the effect and mechanism of Gamikyejakjimogawusul-tang(GKHA) herbal acupuncture on induced rheumatoid arthritis model of DBA/1 mice. Methods : We check effect of GKHA extract on the AST, ALT, Creatinine, BUN of serum and cell viability of GK extract in RAW 264.7 cells to test the stability of this study. In vitro, we measure total phenol contents, total flavonoid contents, DPPH free radical scavenging activity, ABTS cation radical scavenging activity of Gamikyejakjimogawusul-tang, effect of GK extract on ROS(Reactive Ooxygen Species) production to estimate a anti-oxidant capacity, and we also measure effect of GK extract on NO (Nitric Oxid), IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF production in RAW 264.7 cells to estimate a anti-inflammatory efficacy. In vivo, we compare a rheumatoid arthritis manifestation between control and experimental group and estimate a AI. Then we check effect of GKHA on the level of WBC, neutrophil, lympocyte, monocyte in the blood to see the effect of immune cells in blood. In addition we measure effect of GKHA on the level of hs-CRP, IgM, IgG, IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF in serum. We observe effects of GKHA on imaging of cartilage degeneration using micro CT-arthrography in paw hind. And we calculate effects of GKHA that reduced BV ratio, BS/BV ratio using 3D Micro-CT. Lastly we observe effects of GKHA histopathologic examination analysis. Results : 1. The toxicity on liver and kidney was disregardable and the cytotoxicity against RAW 264.7 cells was also disregardable. 1. Total phenol contents and total flavonoid contents in GK extract were in high level. 2. DPPH free radical scavenging activity and ABTS cation radical scavenging activity were increased according to concentration of GK extract 3. ROS production was significantly decreased in GK extract (at 10, $100{\mu}g/ml$). 4. NO, IL-6, TNF-${\alpha}$, MCP-1 production were significantly decreased in GK extract(at 10, $100{\mu}g/ml$). IL-17, GM-CSF production were significantly decreased in GK extract(at 1, 10, $100{\mu}g/ml$). IL-$1{\beta}$, IL-21 production were also decreased but there was no statistical significance. 5. 25x observation after H&E and M-T staining, infiltration of immune cells and subsidence of the cartilage and damage to the synovial cells were decreased. Conclusions : This study showed that GKHA extract had anti-oxidant capacity, anti-inflammatory efficacy. GKHA extract also had inhibiting effect on the process of rheumatoid arthritis and can protect joint and cartilage. So we expect that GKHA extract can be a meaningful treatment to rheumatoid arthritis patients.
