  • Objectives : We investigated the effects of Hominis placenta Herbal acupuncture on rheumatoid arthritis. Methods : We investigated the Type II collagen-induced arthritis test, vascular permeability test, phenyl benzoquinone-induced writhing test, hot plate test, carbon clearance test, determination of prostaglandin $E_2$ content and cyclooxygenase-2 activity test. Results : Hominis placenta Herbal acupuncture suppressed Type II collagen-induced arthritis in DBA/1J mice and vascular permeability with 10.2% inhibition in ICR mice. We see the phenyl benzoquinone-induced writhing test and the hot plate test in the analgesic activity test. In the phenyl benzoquinone-induced writhing test, Hominis placenta Herbal acupuncture showed that it increased its analgesic effect more than the control(test?) by 85.5%. In the hot plate test, it was also shown that the analgesic effect increased more than the control(test) by 32.1%. In the carbon clearance test, the immuno-stimulatory effect showed more than the control(test) by 8.0%. The formation of prostaglandin $E_2$ was also reduced more than the control(test) by 10.1%. Finally, cyclooxygenase-2 activity was inhibitedwith 36.3%. Conclusions : Hominis placenta Herbal acupuncture may be useful for the treatment of rheumatoid arthritis after injection.

  • Objective : Bee venom (BV) has traditionally been used in Oriental medicine to relieve pain and to treat inflammatory disease such as rheumatoid arthritis (RA). Autoimmunity to type II collagen (CII) may involve in the pathogenesis of RA. This study was performed to evaluate the effect of BV on type II collagen induced arthritis (CIA) with the naked eye, a immunohistochemical method and the examination of histology. Method : Male mice were immunized by subcutaneously injection of an $200{\mu}g$ emulsion mixed with bovine CII and complete Freund's adjuvant (CFA) twice for two weeks. In the control group, normal saline was injected, and in the experimental group, BV was applied. Result : The incidence of arthritis, the mean arthritis index and the number of the arthritic limbs of the BV group were all significantly lower than those of the control group. Among the pro-inflammatory cytokines, the production of $TNF-{\alpha}$ in the BV group was also suppressed compared with the control group, but $IL-1{\beta}$ was not. The examination on the histopathology of joints of CIA mice showed the effect of Bee Venom Herbal Acupuncture on the arthritis. Conculusion : Treatment with BV resulted in inhibition of development of arthritis and immune responses to CII.

  • Articular cartilage is an important factor for studying the arthritic diseases. The chondrocyte isolated from cartilage has the characieristic of differentiation and rf-differentiation when cultured in monolayer The bee venom (BV) acupuncture was investigated to examine their abilities on chondrocyte re-differentiation via rabbit chondrocyte primary culture. And the expression profiles of type II collagen (COL2) was analyzed using RT-PCR and western hybridization at third passage chondrocyte. In general, the mRNA expression of type II collagen was reduced step by step with the subculture of the chondrocyte. However, after the BV treatment for 48hr at third passage, the expressions of type II collagen were found to be significantly up-regulated, the same result was confirmed by western blotting. These results suggested that the diluted solution of BV for herb-acupuncture was very effective on the recovery of articular chondrocyte phenotype.

  • Objectives : This study was carried out to understand the immunity responses and anti-oxidation effect of the Gamidaeganghwal-tang(GDT) on rheumatoid arthritis by using the THP-1 cells and the serum of CIA mice. Methods : For this purpose, GDT was orally administerd to mice with rheumatoid arthritis induced by collagen II. To investigate the immunity responses, value of cytokine and gene expression in the THP-1 cell, levels of cytokines in the serum of CIA(collagen type II induced arthritis) mice, number of immunocyte in PBMC of CIA mice were measured. Then, anti-oxidant activity, scavenging activity on DHHP(2,2-diphenyl-1-picrylhydrazyl) free radical and SOD(Superoxide dismutae)-like activity of GDT was observed. Results : 1. The levels of IL-$1{\beta}$, IL-6, IL-8, MCP-1 at 100, $50{\mu}g/m{\ell}$ of GDT were significantly reduced in the THP-1 cell. 2. The levels of TNF-${\alpha}$, COX-2 mRNA expression at 100, $50{\mu}g/m{\ell}$ of GDT and IL-$1{\beta}$, IL-6 at $100{\mu}g/m{\ell}$ of GDT were significantly reduced in the THP-1 cell line. 3. The levels of IL-6, TNF-${\alpha}$ and IL-$1{\beta}$ were significantly reduced in the serum of CIA mice. 4. The absolute number of CD3+, CD4+ and CD8+ cells were significantly induced, CD3+/CD69+, CD3+/CD49+, CD19+, B220+/CD23+ cells were significantly reduced in PBMC. 5. Scavenging activity on DPPH free radical and SOD-like activity were significantly induced in a concentration dependent manner. Conclusions : Taking all these observations, GDT considered to be effective in treating rheumatoid arthritis. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • Background: The roots of Cirsium japonicum var. ussuriense (RCJ) have been used as traditional medicine in Korea for hematuria and hematemesis. These extracts exert anti-oxidative and anti-inflammatory effects by scavenging for free radical and regulating the inflammatory response. However, the effect of RCJ on rheumatoid arthritis (RA) has not been elucidated. Thus, we evaluated the water extract of RCJ (WRCJ) using type II collagen-induced RA models. Methods and Results: RA was induced by immunization with type II collagen. All experimental materials were orally administered daily for three weeks. The positive control group was administered with 0.2 mg/kg methotrexate (n = 7), while the experimental group was administered with WRCJ (100 or 500 mg/kg, n = 7). Serum levels of TNF-alpha, Interleukin 6 (IL-6), and type II collagen IgG (CII) were measured using ELISA. Administration of 500 mg/kg WRCJ decreased the levels of TNF-alpha, IL-6, and CII. Moreover, WRCJ treatment diminished swelling of hind legs and infiltration of inflammatory cells in RA models' synovial membrane. Conclusions: These results indicate that WRCJ could improve RA, reduce inflammatory indicators and synovial inflammation. However, further experiments are required to determine how WRCJ can influence the signal transduction pathway in RA.

  • Human articular chondrocytes (HAC) were cultivated as a monolayer in a serum-free medium for primary culture (SFM-P). An optimized SFM-P provides $95\%$ proliferation rate of that obtainable from primary and secondary chondrocyte cultures grown in a control medium with serum. The gradual decrease in the amounts of synthesized glycosaminoglycan and type II collagen was improved by coating the culture dishes with type IV collagen and fibronectin. A significant improvement in the expression of type II collagen and aggrecan mRNA could be achieved. In addition, the monolayer cultures showed better synthesis of the extracellular matrices than alginate-bead cultures in SFM-P.

  • Purpose: In this study, porous type I collagen scaffolds were cross-linked using dehydrothermal(DHT) treatment and/or 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide(EDC), in the presence and absence of chondroitin-6-sulfate(CS) and cultured autologous chondrocytes(Chondro) for cartilage regeneration. Methods: Cartilage defects were created in the proximal part of the ear of New Zealand rabbits. Four prepared types of scaffolds(n=4) were inserted. The groups included Chondro-Collagen-DHT(Group 1), Chondro- Collagen-DHT-EDC(Group 2), Chondro-CS-Collagen- DHT(Group 3), and Chondro-CS-Collagen-DHT-EDC (Group 4). Histomorphometric analysis and cartilage-specific gene expression of the reconstructed tissues were evaluated 4, 8, and 12 weeks after implantation. Results: EDC cross-linked groups 2 and 4 regenerated more cartilage than other groups. However, calcification was observed in the 4th week after implantation. CS did not increase chondrogenesis in all groups. Cartilage-specific type II collagen mRNA expression increased in the course of time in all groups.Conclusion: EDC cross-linking methods maintain the scaffold and promote extracellular matrix production of chondrocytes.

  • Objectives: To investigate anti-inflammatory and anti-arthritic effects of Gyulpidaehwangbakcho-tang (GDBT) extract in a murine model of rheumatoid arthritis. Methods: The mice received $100{\mu}g$ of bovine type II collagen in Freund's complete adjuvant by intradermal injection at the base of the tail on day 0 and a booster injection on day 21. The mice were orally administered with GDBT (200 or 50mg/kg dissolved in distilled water) daily from day 1 to day 21 after arthritis incidence, and monitored for disease incidence and the severity of arthritis up to day 21. In order to evaluate the effect of GDBT on disease progression, we examined pro-inflammatory cytokines including IL-$1{\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II. Results: GDBT produced a significant and dose dependent inhibition of arthritis and inflammation during the entire duration of the study. This action was characterized by the decreased production of IL-$1{\beta}$, IL-6, TNF-${\alpha}$, COX-2, and NOS-II in vivo. Conclusion: We believe that the anti-arthritic activity of GDBT is due to its modulatory effect on the expression of pro-inflammatory cytokine in the synovium. Our results contribute towards validation of the traditional use of GDBT in the treatment of RA and other inflammatory joint disorders.

  • Blends of collagen dispersion (COL) with poly(vinyl alcohol) (PVA) in different weight ratios were investigated by oscillatory rheometry, Fourier transform-infrared spectroscopy and scanning electron microscopy. It was found that even with 80% of PVA, the COL/PVA blends behaved more like collagen dispersion than pure PVA solution in the dynamic thermal and frequency processing, for instance, a dominant elastic appearance (G'>G"), a similar shear thinning behavior and the thermal denaturation below $40^{\circ}C$. However, influence on the blend behaviour by PVA was noticeable, for instance, an increase of dynamic denaturation temperature, the decreasing intensity of amide I, II and III bands as well as the diminishing irregular pores on the surface of blends. The interaction between collagen and PVA could be observed, especially at the regions with low content or high content of PVA.
