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.

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.

Oral administration of antigen has long been used in the induction of immune tolerance in various animal models of autoimmune diseases including rheumatoid arthritis (RA). Alleveation of arthritogenic symptoms has been reported from RA patients who received oral administration of type II collagen (CII) without side effects, however its rather inconsistent therapeutic efficacy and variation among patients calls for more detailed investigation on the mechanism of oral tolerance to be settled as regular treatment for RA. In an attempt to understand the immunogenic processes underpinning tolerance induction by orally administered CII, we analyzed changes in the expression of costimulatory molecules and STAT/SOCS signaling messengers in the mouse model of collagen induced arthritis (CIA). We found thatin the spleen of CIA mice, that has been undergone repeated oral feeding of CII prior to the induction of arthritis, showed increased promortion of CTLA4 expressing lymphocytes than in the spleen of PBS fed control. On the other hand, cells expressing CD28 or ICOS were decreased in the spleen of tolerized mice. Tolerance induction by oral CII administration also enhanced the expression of STAT6 in both RNA and protein level, while not affecting the expression of STAT3. The expression of SOCS3, which hasbeen known to transmit STAT-mediated signals from Th2 type cytokines, remained unchanged in the spleen of tolerized mice. Interestingly transcript of SOCS1, which has been associated with Th1 related pathways, was only visible in the spleen of tolerized but not of control mice, suggesting that as in the case of IL-6 signaling, it may exert a feed back inhibition toward the Th1 type stimulation.

Objectives: This study was carried out to know the effects of Gwan-Jul-Bang-7 (hereafter referred to GJB-7) on the inhibition of arthritis induced by collagen on the mouse. Methods: To assess the effects of GJB-7 on mouse with arthritis induced by collagen II, we conducted several experiments such as analysis of cytotoxicity, hepatotoxicity, arthritis index, total cell number of draining lymph nodes and paw joints, value of immunocyte in PBMC (peripheral blood mononuclear cell), DLN (draining lymph node) and paw joint, measurement of cytokine and anti-collagen II, observation of the histological changes of joint. Results: 1. Cytotoxicity against HFC (human fibroblast cells) was not observed in any concentration and hepatotoxicity was not observed in the GJB-7 treated group. 2. The incidence of arthritis significantly decreased. 3. Total cell number of draining lymph nodes significantly increased and total cell number of paw joints significantly decreased. 4. The percentage of $CD8^+$ cells in PBMC (peripheral blood mononuclear cell) significantly increased. The percentage of $CD3^+/CD69^+$, and $CD3^+/CD49b^+$ cells in PBMC significantly decreased. 5. The percentage of $CD19^+,\;CD3^+$, and $CD4^+/CD25^+$ cells in DLN (draining lymph nodes) significantly increased. The percentage of $B220^+/CD23^+$ cells in DLN significantly decreased. 6. The percentage of $CD3^+,\;CD4^+$, and $CD11b^+/Gr-1^+$ cells in paw joints significantly decreased. 7. The production of TNF-$\alpha$, IL-6, and MCP-1 significantly decreased. 8. Anti-collagen II in serum significantly decreased. 9. With the hematoxylin and eosin stain, inflammation of joint decreased. Under Masson's trichrome stain, the cartilage destruction and synovial cell proliferation and the expression of collagen fibers decreased. Conclusions: Comparison of the results for this study showed that GJB-7 had immunomodulatory effects. So we expect that GJB-7 could be used as an effective drug for not only rheumatoid arthritis but also another auto-immune diseases.

Underlying malocclusions and dentofacial deformities are often related to variations in the craniofacial development. Type I and type II collagens are considered the major collagens of bone and cartilage respectively. Monitoring the patterns of those protein expressions during development will Provide a basis for the understanding of normal and abnormal growths. This study was undertaken to investigate the morphogenetic changes and the expression patterns of type I and II collagen proteins involved in the developing mandible of human embryos and fetuses. 50 embryos and fetuses were studied with Hematoxylin and Eosin, Alcian, blue-PAS, Masson Trichrome, md Immunohistochemical stains. The results were as follows : 1. A 13.5 mm embryo showed the stomatodeum with dental lamina, maxillary and mandibular processes. Meckel's cartilage appeared in the mandibular arch of a 20.5 mm embryo. New bone formation was bilaterally initiated at the outer side of middle portion of Meckel's cartilage of 22-38 mm embryos. 2. Meckel'cartilage was resorbed at the 15th week fetus. The endochondral ossification was observed where there was direct replacement of cartilage by bone. Meckel'cartilage disappeared and membraneous ossification were observed at the 25th week. 3. Before the appearance of Meckel's cartilage, the expression of type I collagen was moderate at the odontogenic epithelium of maxillary & mandibular process, but mild for the expression of type II collagen. 4. During the appearance of Meckel's cartilage and new bone formation, the immunoactivity of type II collagen was more expressed than type I collagen at the Meckel's cartilage and new bone. 5. During intrarmembranous bone formation, the expression of type II collagen was rare in the bony trabeculae. There was a switch for the expression of collagens from type II to type I during the appearance of Meckel's cartilage.

It has not been elucidated whether the initiation of condylar development of the mandible is related with the periosteum of the mandible, or if it derives from a separate programmed blastema not related with the mandible. Also, although the mandibular condylar cartilage is known to promote growth, few studies have dealt with molecular-biologic mechanisms such as the expression of specific genes according to the differentiation of the mandibular condyle. To elucidate the unique cellular characteristics, development, and differentiation process of the mandibular condyle, an examination of expressions of genes characteristic of cartilage and bone were carried out using RT-PCR and mRNA in situ hybridization. 1. Type? collagen mRNA was detected with type II collagen mRNA in the differentiation and growth process of the cartilage of the mandibular condyle. TypeII collagen mRNA was demonstrated in the whole resting md upper part of the poliferative zone, whereas type II collagen mRNA was observed in the resting, proliferative and upper hypertrophic cartilage zone of the mandibular condyle. 2. The condylar cartilage rapidly increased in size due to the accumulation of hypertrophic chondrocytes as characterized by the expression of type II collagen mRNA during postnatal development. 3. BMP-4 mRNA was present in the anlage of the future condylar process and also in the ossifying mandibular body. 4. IHH mRNA was limited exclusively to the lower part of the proliferative zone and the upper part of the hypertrophic cartilage zone during condylar development. These findings were different from those in the growth-plate cartilage of the long bone, indicating a characteristic feature of the differentiation of the chondrocytes in the condylar cartilage present in prenatal and postnatal development. Furthermore, it was also suggested that chondroblasts of condylar cartilage rapidly differentiate into hypertrophic chondrocytes with increased functional Load force such as muscle activity and mastication.

Articular cartilage is an important target for studying the arthritic diseases. To verify the therapeutic effects of bee venom herb-acupuncture in vivo, 3${\mu}$l of diluted solution of bee venom for herb-acupuncture were injected into articular cavity once a day during 3 months after making full-thickness defects in rat articular cartilage. Histological examination and immunohistochemistry indicated that the chondrocyte-like tissue was formed during the repair process of cartilage injury, and the expression of a cartilage-specific protein, collagen type II, were significantly activated. It means that the expression of the gene encoding type I collagen was down-regulated, whereas those of collagen type II were up-regulated. Histological examination by hematoxylin-eosin staining indicated that the cells regained their original round morphology. In addition, a homogeneous distribution of articular cartilage extracellular matrices was detected around the cells. These results suggested that bee venom herb-acupuncture was very effective on the recovery of articular chondrocyte phenotype.

This study was conducted to determine the analgesic effect of onion and acanthopanax senticosus mixture extract using the rheumatoid arthritis rat model. Rheumatoid arthritis model was made by the intradermal injection of type II collagen emulsified. Rats were divided into four groups: (1) Sham group(n=5), (2) Control group(administered DW 3 $m{\ell}$/1 day after RA induced, n=7), (3) Experimental group I(administered Onion extractor 600 mg/3 $m{\ell}$/1 day after RA induced, n=7). (4) Experimental group III(administered Onion and Acanthopanax senticosus mixture extractor 600 mg/3 $m{\ell}$/1 day after RA induced, n=7). After that, we examined the arthritic index, paw edema, pain threshold at 1st, 14th, 28th days. And also we examined histopathologic study(safranin-O green), immunohistochamical stain(COX-2) of knee joint at 28th days. Arthritic index, paw edema and pain threshold test were decrease in experimental group I, II than control group. Especially group II was most significantly inhibit effect than the other groups at 28th days. On the histopathologic view, all experimental groups were relieved and reproduced the erosion of arthritic site compared with control group. All experimental groups were COX-2 positive cells in the immunohistological stain of the knee joint were significantly decreased compared with control group. Especially group II was most significantly decreased than the other groups at 28th days. Onion and Acanthopanax senticosus mixture extractor can be used for curing rheumatoid arthritis. Anti-inflammatory effects may be somewhat better in combination of Onion and Acanthopanax senticosus.
