  • Objectives & Methods : The purpose of this study is to observe the effects of Coicis Semen Herbal-acupuncture solution (CS-HAS) at the Joksamni (ST36) on the collagen-induced arthritis in the DBA/1J mouse. The author performed several experiments to analyze the effects of CS-HAS on arthritis; change of the weight; the spleen size and adhesion rate; serum cytokine levels; serum antibody levels; changes of immunocyte counts; the histological changes of joint. Results : In the Coicis Semen Herbal-acupuncture (CS-HA), arthritis index, the incidence of arthritis, and the degree of joint edema were decreased. In CS-HA, there was no weight loss. The size of the spleen, adhesion rate, and the edema and transformation of joint were lowered. In CS-HA, the levels of IL-1${\beta}$, IL-6, TNF-${\alpha}$, IFN-${\gamma}$, IgG, IgM, and anti-collagen II in serum and the levels of IFN-${\gamma}$, IL-4, IL-10 in spleen were significantly decreased. In CS-HA, the expression ratios of $CD45^+$ to $CD3e^+$ and $CD8^+$ to $CD4^+$ were decreased. Also, the overall $CD4^+/CD8^+$ cell ratio was lowered in spleen. Ratios of the $CD4^+/CD25^+$, $CD45^+/CD69^+$ cells were decreased in lymph nodes. In addition, ratios of the $CD3^+/CD69^+$, $CD11b^+/Gr-1^+$ cells were also decreased in synovium. In the histological study, the cartilage destruction and synovial cell proliferation, and collagen fiber destruction were decreased with CS-HA treated group. Conclusions : From the results mentioned above, it is suggested that CS-HA at the ST36 has several significant effects on the collagen-induced arthritis.

  • Angiogenesis, the formation of new capillary blood vessels, is a tightly regulated process. Under normal physiological conditions, angiogenesis only takes place during embryonic development, wound healing, and female menstruation. Dysregulation of angiogenesis is associated with many diseases, such as cancer, rheumatoid arthritis, psoriasis, and proliferative retinopathy. The growth and expansion of adipose tissue require the formation of new blood vessels. Adipose tissue is probably the most highly vascularized tissue in the body, as each adipocyte is surrounded by capillaries, and the angiogenic vessels supply nutrients and oxygen to adipocytes. Accumulating evidence shows that capillary endothelial cells communicate with adipocytes via paracrine signaling pathways, extracellular components, and direct cell-cell interactions. Activated adipocytes produce multiple angiogenic factors, including VEGF, FGF-2, leptin, and HGF, which either alone or cooperatively stimulate the expansion and metabolism of adipose tissue by increasing adipose tissue vasculature. Recently, it was demonstrated that antiangiogenic herbal Ob-X extracts and Korean red ginseng extracts reduce adipose tissue mass and suppress obesity by inhibiting angiogenesis in obese mice. Thus, angiogenesis inhibitors provide a promising therapeutic approach for controlling human obesity and related disorders.

  • Although the arthritis symptoms observed in the K/BxN model have been shown to be dependent on the functions of T and B cells specific to the self antigen glucose-6-phosphate isomerase, less is known about the in vivo roles of $CD4^{+}CD25^{+}$ regulatory T($T_{reg}$) cells in the pathology of K/BxN mice. We determined the quantitative and functional characteristics of the $T_{reg}$ cells in K/BxN mice. These mice contained a higher percentage of $Foxp3^+\;T_{reg}$ cells among the $CD4^+$ T cells than their BxN littermates. These $T_{reg}$ cells were anergic and efficiently suppressed the proliferation of $na\ddot{i}ve$ $CD4^+$ T cells and cytokine production by effector $CD4^+$ T cells in vitro. Antibody-mediated depletion of $CD25^+$ cells caused K/BxN mice to develop multi-organ inflammation and autoantibody production, while the symptoms of arthritis were not affected. These results demonstrate that despite the inability of the $T_{reg}$ cells to suppress arthritis development, they play a critical role protecting the arthritic mice from systemic expansion of autoimmunity.

  • Objective : To review the trend of the study related to Leech therapy and to establish the hereafter direction for the study on Leech therapy. Methods : I reviewed and analyzed all the theses published in Domestic and Foreign research institution from 1990 to 2009. Results : The following results were obtained in this study. 1. Analyzed number of theses published, there was no significance per year. 2. Classified by theme of journal, journals related to surgery were most(41 journals, 75.92%) among 54 kinds. 3. Classified by theses by research method and thesis types, case report accounted for nearly twothirds (52 pieces, 68.42%) of all theses and consideration of document was next(9 pieces, 11.84%). 4. With the most case of venous congestion after plastic and reconstructive surgery(33 pieces, 63.46%), leech therapy was effective on illnesses such as haematoma, macroglossia, purpura, varicous vein, avulsion injury, neurovascular compression, diabetic neuropathy, penoscrotal oedema, buerger's disease, rheumatoid arthritis. 5. Two most appeared adverse effects were anemia and infection. Immediate blood transfusion was done for recovering anemia and prophylactic 3rd generation antibiotics to infection were emphasized in more than half of case reports. 6. All of consideration of documents was retrospective study of cases related leech therapy and 3 pieces of them emphasized prophyratic antibiotic treatment for preventing infection. 7. The study of clinical trail type started first in 2002 and osteoarthritis of knee and carpometacarpal joint were main target. As see above result, Leech therapy was effective cure and could be used in disease induced by venous congestion. And I think that it is necessary to perform additional study related to solution of problems about leech therapy and protocol for using in clinical practice.

  • Objective: Bee venom (BV) has been used for the treatment of inflammatory diseases such as rheumatoid arthritis and relief of pain in Oriental medicine. The two main components of BV are melittin and phospholipase A2 (PLA2). Of these, melittin, the major active ingredient of BV, has been reported to induce apoptosis and to possess anti tumor effects. Several studies have established that the agents inducing apoptosis in target organs suppress tumorigenesis. As the other component, PLA2 has been reported to induce neurite outgrowth in PC12 cells. However, there was no report about proliferative effect of BV in neuronal cells. In order to examine the effect of BV on glioma cell, human glioma cell line, U87 was used. Methods: Analysis of proliferation was confirmed by MTT assay. BV increased cell number through dose and duration dependent manner and these effects are apparent at a concentration of 10 ug/ml. To observe which signaling molecules will be activated by BV, phosphorylation of Akt, MAPK, PYK2 or CREB were examined by Western blot analysis. To study the long term effect of BV in U87 cells, the image of cells treated with BV for 4 days were obtained. Results: The phosphorylation levels of PYK2 and Akt were increased at 5 min after addition of 10 ug/ml of BV and sustained to 2 hours. On the other hand, phosphorylation of MAPK and CREB were increased at 5 min, maximum at 10 min, and returned to 30 min. These imply that BV may activate two different signaling pathways, PYK2/Akt and MAPK/CREB. BV treated cells showed increased neurite number and length. Conclusion: These results propose that BV may induce differentiation as well as proliferation of U87 cells through the activation of PYK2/ Akt and MAPK/ CREB.

  • In Korea, China, and Japan, Paeonia lactiflora Pall (PL) has been used in the treatment of rheumatoid arthritis, hepatitis, and fever for more than 1200 years. It has been reported that PL has protective effects against $H_2O_2$-induced oxidative stress and LPS-induced liver inflammation. However cellular and molecular mechanism of PL protection against oxidative stress has not fully been elucidated. Here, we describe that the water-soluble extract of PL decreased $H_2O_2$-induced hepatotoxicity. This hepatoprotective effect of PL is reason to decrease the level of intracellular reactive oxygen species (ROS) and increase expression of heme oxygenase 1 (HO-1) and heat shock protein 72 (HSP72) which proteins are involved in protecting the cells from stress like as oxidative stress. We also elucidated that hepatoprotective effect of PL was abolished by knock down of HO-1 and HSP72 by siRNA. These results suggest that the increasing of HO-1 and HSP72 protein by PL treatment might be participated in hepatoprotective effect against oxidative stress such as $H_2O_2$.

  • Impairment of balance between bone-resorbing osteoclasts and bone-forming osteoblasts result in bone disease. Especially, increased osteoclast formation and activity are responsible for bone diseases such as osteoporosis, rheumatoid arthritis, periodontal disease. Natural metabolites of plants have recently received much attention as an alternative tools for the development of novel therapeutic strategy. The aim of this study was to search the natural products to inhibit osteoclast differentiation and was to evaluate of its mechanism. Water extract of Gastrodia elata Blune significantly inhibited receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation in bone marrow macrophages (BMMs) in a dose dependent manner. However, water extract of Gastrodia elata Blune did not affect cytotoxicity when compared with control. The mRNA expression of c-Fos, NFATc1, and TRAP induced by RANKL was inhibited by water extract of Gastrodia elata Blune treatment. Also, water extract of Gastrodia elata Blune inhibited the protein expression of c-Fos and NFATc1 expression in BMMs treated with RANKL. Water extract of Gastrodia elata Blune suppressed the phosphorylation of p38 induced by RANKL. In general, RANKL considerably inhibited the expression level of Id2 and MafB known as negative regulators of osteoclastogenesis, but RANKL did not inhibit Id2 and MafB expression in BMMs when it was co-treated with Gastrodia elata Blune. Taken together, these results suggest that Gastrodia elata Blune may be a useful drug in the treatment of bone-related disease.

  • Pigmented villonodular synovitis, synovial chondromatosis, long-standing rheumatoid arthritis, hemophilic arthropathy, chronic tophaceous gout, amyloid arthropathy, tuberculous arthritis, and hemangioma are the synovial diseases showing low signal intensity on T2-weighted image. Synovial deposition of hemosiderin, urate, and amyloid and fibrosis or caseous necrosis of hypertrophied synovium are known as the pathologic causes of T2 signal intensity. Because of the low incidence of the synovial lesions showing T2 low signal intensity, recognition of these diseases would be helpful for the exact diagnosis.
