Objective : The purpose of this study is to investigate the immunological effect of Ramulus Cinnamomum aqua-acupuncture on the cellular immune response in mice with LPS induced arthritis. Methods : All the BALB/C mice used in this study were bred and maintaned in our pathogen-free mouse colony and were 6wk of age at the start of the experiment. The experimental model of arthritis was induced by injeciton of 300${\mu}g$/kg LPS in mice knee joint. Ramulus Cinnamomum aqua-acupuncture was injected into Yangnungchon(Gb34) of mice 2daily for 14days. Immunohistochemical analysis was carried out to assess CD4+, CD8+, CD11b, IL-$1{\beta}$, IL-2R and CD106 expression in common iliac lymph nodes and synovial menbrane after stimulation with Ramulus Cinnamomum. Electron microscopy was carried out to assess change of synovial membrane. Ramulus Cinnamomum aqua-acupuncture stimulation group was compared to control group and non stimutated with aqua-acupuncture. Resutts : At day 14 post arthritis onset, Immunohistological studies using monoclonal antibodies showed that Ramulus Cinnamomum aqua-acupuncture goup had decreased expression of CD4+, CD8+, CD11b, IL-$1{\beta}$, IL-2R and CD106 at common illiac lymph nodes and synovial membrane compared with control group. Conclusions : Ramulus Cinnamomum aqua-acupuncture stimulation inhibited the development of cellular immunity to LPS-induced arthritis in mice. Thus, aqua-acupuncture stimulation may have preventive effects on autoimmune inflammatory joint diseases. The effects of AA on immune function and disease activity in patients with RA warrant further investigation.

Receptor activator of NF-${\kappa}B$ ligand (RANKL) is an essential cytokine for osteoclast differentiation, activation and survival. T lymphocytes such as $T_{17}$ cells, a subset of T helper cells that produce IL-17, play an important role in rheumatoid arthritic bone resorption by producing inflammatory cytokines and RANKL. It has not yet been clearly elucidated how T cell activation induces RANKL expression. T cell receptor activation induces the activation of nuclear factor of activated T cell (NFAT) and expression of its target genes. In this study, we examined the role of NFAT in T cell activation-induced RANKL expression. EL-4, a murine T lymphocytic cell line, was used. When T cell activation was induced by phorbol 12-myristate 13-acetate (PMA) and ionomycin, RANKL expression increased in a time-dependent manner. In the presence of cyclosporin, an inhibitor of NFAT activation, this PMA/ionomycin-induced RANKL expression was blocked. Overexpression of either NFATc1 or NFATc3 induced RANKL expression. Chromatin immunoprecipitation results demonstrated that PMA/ionomycin treatment induced the binding of NFATc1 and NFATc3 to the mouse RANKL gene promoter. These results suggest that NFATc1 and NFATc3 mediates T cell receptor activation-induced RANKL expression in T lymphocytes.

Matrix metalloproteinases (MMPs) play an important role in the normal morphogenesis, maintenance, and repair of matrix and also have important functions in pathologic conditions characterized by excessive degradation of extracellular matrix, such as rheumatoid arthritis, osteoarthritis, periodontitis and in tumor invasion and metastasis. In this study, expression of MMP-1 and -2 mRNA in retrodiscal tissue of the temporomandibular joint (TMJ) was examined and compared with magnetic resonance imaging (MRI) and surgical findings. MMP mRNAs in the retrodiscal tissue samples were detected by reverse transcription - polymerase chain reaction. TMJ internal derangement (ID) was categorized as normal disc position, disc displacement with reduction, early stage of disc displacement without reduction (DDsR) and late stage of DDsR. TMJ osteoarthrosis (OA) was classified with normal, mild and advanced OA. The amount of synovial fluid collection was divided into not detected, small, large and extremely large amount on MR T2-weighted imaging. Perforation and adhesion were examined during open surgery of the TMJ. Six out of 37 samples were excluded because of little amount of extracted total mRNA. MMP-2 mRNA was detected whole joints, and so the MMP-2 mRNA seems to be expressed normally in retrodiscal tissue. However, MMP-1 mRNA was expressed in 8 of 31 joints. Frequencies of MMP-1 mRNA expression according to the TMJ IDs, amount of synovial fluid and surgical findings made no significant difference. MMP-1 mRNA was detected more frequently in OA groups (7/16 joints, 43.8%) than in normal bony structure group (1/15 joints, 6.7%). Expression of MMP-1 mRNA in retrodiscal tissue might be related with OA of the TMJ.

Inflammatory cells may produce active species of oxygen in antimicrobial defense. While such species can directly damage surrounding tissue, their major secondary role may be to mediate important components of the inflammatory response. Superoxide dismutase, antioxidant, have significant anti-inflammatory properties in rheumatoid arthritis, ischemic tissue injury and gastrointestinal disease. Increased oxidative product formation diseases. And superoxide dismutase produced by Porphyromonas Gingivalis is resistant to killing by polymorphonuclear leukocyte. The purpose of this study was to investigate on the effects of superoxide dismutase in 3T3 fibroblast and in experimental gingivitis in the rats. The effect of superoxide dismutase(SOD) to cell morphology and cell activity was measured in cultured mouse 3T3 fibroblast. After experimental gingivitis were induced by lipopolysaccharide(LPb) and bovine serum albumin(BSA), injection of SOD were done. WBC count and histologic findings were observed at 1, 2, 3, and 7 days. The results were as follows; 1. There was a little difference between LPS treated groups and SOD treated groups in 3T3 fibroblast morpholoy. 2. There was no difference between only SOD treated groups (except SOD 150U at 3days) and control in 3T3 fibroblast activity. 3. LPS $0.5{\mu}g/ml$ and SOD treated groups (except 150U) had decreased 3T3 fibroblast activity and no significant difference at 3 days. 4. LPS $5.0{\mu}g/ml$ and SOD treated groups were significantly increased cell activity of 3T3 fibroblast than control group at 1 day(P<0.05). 5. In LPS induced gingivitis, the number of leukocytes in SOD treated was significantly decreased than in saline treated at 1 day(P<0.05). 6. In histopathologic findings of LPS or BSA induced gingivitis, inflammatorycell infiltration in SOD treated groups were less than in saline treated group at 1, 2 and 3 days.

Cardiovascular diseases arising from atherosclerosis are the leading causes of mortality and morbidity worldwide. Lipid-lowering agents have been developed in order to treat hypercholesterolemia, a major risk factor for atherosclerosis. However, the prevalence of cardiovascular diseases is increasing, indicating a need to identify novel therapeutic targets and develop new treatment agents. Adenosine receptors (ARs) are emerging as therapeutic targets in asthma, rheumatoid arthritis, cancer, ischemia, and inflammatory diseases. This study assessed whether LJ-1888, a selective antagonist for $A_3$ AR, can inhibit the development of atherosclerosis in apolipoprotein E knock-out ($ApoE^{-/-}$) mice who are fed a western diet. Plaque formation was significantly lower in $ApoE^{-/-}$ mice administered LJ-1888 than in mice not administered LJ-1888, without any associated liver damage. LJ-1888 treatment of $ApoE^{-/-}$ mice prevented western diet-induced hypercholesterolemia by markedly reducing low-density lipoprotein cholesterol levels and significantly increasing high-density lipoprotein cholesterol concentrations. Reduced hypercholesterolemia in $ApoE^{-/-}$ mice administered LJ-1888 was associated with the enhanced expression of genes involved in bile acid biosynthesis. These findings indicate that LJ-1888, a selective antagonist for $A_3$ AR, may be a novel candidate for the treatment of atherosclerosis and hypercholesterolemia.

The purpose of this study was to explore self management of pain by folk remedies in patient with chronic arthritis. The participant of this study were 90 volunteers who were visit C hospital and who want to counsel with researcher for their pain control by convenient sampling method. The results of this study were summarized as follows : The subjects were the 90 patients who had been diagnosed rehumatoid arthritis(52.5%)and osteoarthritis(47.8). 93.3% of participants were women. Mean age of participants was 53.7 and duration of arthritis was 7 years. Mean pain score was 5.5cm. Eighty five kinds of folk remedies were used for pain management. The mean cost for folk remedies was 3,723,207 won and the patients with rheumatoid arthritis paid to folk remedies as much as 3 times. The perceived effect score of pain management by folk remedies was 2.932(the range of perceived effect score were 0-10cm). Percentage of discontinue to use folk remedies was 82.8% and the major reason of discontinue to use folk remedies was no effect to pain control(50.4%). Some participants(30.5%) were experienced side effect such as exacerbation of pain(50.5%). In conculusion, chronic arthritis patients have been experienced various kind of folk remedies for the management of their pain. But the effect of pain control was very low. The important weakness of folk remedies were economical waste and loss of opportunity to treatment for arthritis. The nurse who care for arthritis should be teach about weakness of folk remedies for their pain control to the patients with arthritis.

Osteoclasts are bone-resorbing multinucleated cells derived from the monocyte/macrophage lineage. The differentiation of osteoclasts are regulated by osteoblastic cells expressed RANKL, which is the most critical molecule for osteoclast differentiation. In this study, we found that water extracts of cuscuta inhibited RANKL-mediated osteoclast differentiation by direct action on bone marrow macrophages (BMMs) without cytotoxicity. In BMMs, water extracts of cuscuta inhibited the mRNA expression of c-Fos, NFATc1, TRAP, and OSCAR. Also, the protein expression of c-Fos and NFATc1 was inhibited by water extracts of cuscuta treatement. Water extracts of cuscuta inhibited the phosphorylation of p38, ERK, and JNK in BMMs treated with RANKL. However, water extracts of cuscuta did not inhibit RANKL-induced I-${\kappa}B$ activation. Water extract of cuscuta failed to inhibit bone resorption by osteoclasts cultured on hydroxyapatite plates. These results suggest that cuscuta may be a promising drug for use against bone disorders such as osteoporosis and rheumatoid arthritis.
