Thirty-nine patients (forty-four joints) who had been diagnosed as having meniscus perforation of the temporomandibular joint by inferior joint space arthrography and had been treated by surgical procedures were evaluated retrospectively. Information of clinical findings, arthrotomographic findings and surgical findings was collected on a standardized form and evaluated. The results were as follows: 1. On the 34 patients of 38 joints which were surgically confirmed perforation of meniscus or its attachments of the temporomandibular joint, there were 29 females and 5 males (5.8:1). The average age was 36 years (range 17 to 70). 2. The common clinical findings of group that had meniscus displacement without reduction and with perforation were pain on the affected joint and limitation of mouth opening. In the group showing meniscus displacement with reduction and with perforation the common clinical findings were pain and clicking on the affected joint. 3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without reduction and with perforation, 6 joints (15.8%) showed anterior meniscus displacement with reduction and with perforation. 4. Joints categorized arthrotomographically as having meniscus displacement without reduction and with perforation were less likely to have full translation of the condyle in comparison with the normal or meniscus displacement with reduction and with perforation groups. (p<0.05) 5.The arthrographic findings of 44 joints having meniscus perforation were compared with surgical findings, there were 6 false positive findings of meniscus perforation, the reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with surgical findings. 6. On the site of perforations of 38 joints which were surgically confirmed perforation of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at the junction of the meniscus and posterior attachment, forteen (36.9%) were located at the posterior attachment and one (2.6%) was at the meniscus itself.

Objectives This study was carried out to know the effects of Keonbodan (hereinafter referred to KBD) in osteoarthritis induced by Monosodium iodoacetate(hereinafter referred to MIA) on Wistar rat. Methods Osteoarthritis was induced by injection of MIA into left knee joint cavities of rat. Osteoarthritis rats were divided into 4 groups (normal (n=6), control (n=6), indomethacin (n=6), KBD (n=6) group). The control group was administered normal saline and indomethacin group was administered indomethacin (2 mg/kg). And the KBD group was administered KBD (142 mg/kg). Each groups were administered by orally for 4 weeks. This experiment were carried out in vivo. In vivo, at the end of the experiment (5 weeks after MIA injection), effects on hepatotoxicity and nephrotoxicity, cytokines in serum, arachidonic acid, osteocalcin, MMP-9, TIMP-1 and cartilage volume were evaluated. And histopathological examinations on the articular structures of knee joints were performed. Results 1. In weight-bearing measurement, level of weight was increased. 2. In order to hepatotoxicity and nephrotoxicity, ALT, AST, BUN and creatinine were tested. And there were no significant changes. 3. In serum, levels of TNF-$\alpha$, IL-$1{\beta}$ were significantly decreased. IL-6 was insignificantly decreased. 4. In serum, level of MMP-9 and TIMP-1 was decreased. 5. In serum, level of $LTB_4$, $PGE_2$ and osteocalcin was decreased. 6. In ${\mu}$CT-arthrography, the cartilage volume was greater than that of the control group. 7. The joint damage induced by osteoarthritis was lesser than the control group in histopathologic observation (H&E, Safranin-O staining). Conclusions These results demonstrated that KBD suppressed the osteoarthritis- inducing effects of MIA in rat. And further studies are required to find out more effective substance and anti-osteoarthritic mechanism in the future.

The authors analyzed the clinical findings, radiological findings and their correlations in the temporomandibular joint disorders. The results were as follows: 1. The most prevalent age group was in the first decade, then the second decade and the third decade. Female were more common with a ratio of 3.4:1. 2. The most common clinical findings was the pain on open mouth position (42.3%), then came the clicking and limitation of mouth opening. 3. The most common bone change on the condyle side was the erosion, then came the flattening, the osteopyte and the sclerosis in that orders. 4. In the case of the crepitus, the coarse crepitus showed more radiological change than the fine crepitus. The 27% of the patients with crepitus showed the bone change and the patients with crepitus showed more bone change than any other clinical symptoms. 5. In the case of the mouth opening limitation, the evaluation of the translatory movement by transcranial projection was in accordance with the clinical evaluation. 6. The correlation between the clinical symptom and the condylar position within the mandibular fossa was not present and in the case of diagnosis of disc displacement, the transcranial projection seemed not to be able to substitute for the arthrography. Radiographically, the most prevalent age group which showed the bone change was in the first, the second and the third decade. And the bone change seemed to have no relationship with aging.

A growing number of people are enjoying sports activity with a rise in national income. In this current, many patients complain of traumatic shoulder dislocation and chronic instability with bony Bankart lesion. Computed tomography arthrography is good diagnostic modality for bony Bankart lesion. It is important to consider the patients' factors such as occupation, sports activity, size of preoperative glenoid bone loss before decision of treatment. As development of arthroscopic treatment, there is no significant difference in the result of bony Bankart repair between arthroscopic surgery and open surgery. However, open surgery should be considered for patients with preoperative glenoid bone loss more than 25% or in need of collision sports activity.

The purpose of this study was to prove the relationship between arthrographic and clinical features in temporomandibular joint disorders. In order to carry out this study, ninety-eight arthrographic examinations of temporomandibular joints were performed on eighty-two patients who had the temporomandibular joint disorders. As the arthrographic examination, the cases were classified in three groups, disk displacement with reduction, disk displacement without reduction, within normal limit. After this, the cases were clinically examined, and the results were compared and analyzed in each other group. The obtained results were as follows; 1. As the classification by arthrographic examination, three groups (disc displacement with reduction, disc displacement without reduction, within normal limit) were 41 ％, 54％, 5％ of total cases in this study, respectively. 2. The third decade(65％) was most frequent in this study. The average age of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 24, 28, 21, and disc displacement without reduction group was higher than any other group. 3. In the chief complaint, pain was the most frequent in all three groups. Joint sound was also frequent in disc displacement with reduction group, but in disc displacement without reduction group, limitation of mouth opening was more frequent. 4. Of the various pain, the movement pain was most frequent ( 61 ％) in this study. In joint sound, click(63％) was the most frequent in disc displacement with reduction group, but sound history(42％) and no sound (31 ％) were more frequent in disc displacement without reduction group. 5. The average maximum opening of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 44mm, 32.9mm, 44mm, and disc displacement without reduction group was less than any other group. 6. The masticatory disturbance of each group (disc displacement with reduction, disc displacement without reduction, within normal limit) was 53％, 79％, 40％, and the trauma history of each group was 50％, 40％,60％.

Objectives: This study was intended to clarify how Jakyakkamchobuja-tang (hereinafter referred to JKBT) affects mice of C57BL/10 whose osteoarthritis was induced by papain. Methods: Osteoarthritis was induced in mice by injecting papain in the knee joint. Mice were divided into 4 groups (n=6). The normal group were not treated at all whereas the control group (OAC-control) were induced for osteoarthritis by papain and oral medicated with 200 ul of physiological saline per day. The positive comparison group (OAC-$Joins^{(R)}$) were injected with papain and after 7 days, 100 mg/kg of $Joins^{(R)}$ were medicated with 200 ul of physiological saline mixed. The experimental group (OAC-JKBT) were injected with papain and after 7 days were medicated with 400 mg/kg of JKBT mixed with 200 ul of physiological saline. OAC-$Joins^{(R)}$ and OAC-JKBT were oral medicated for each substance for a total of 4 weeks, once per day. After experiments (from 1 week after injection of papain to 4 weeks elapsed), the function of liver and kidney, inflammation cytokine values within serum, degree of revelation for inflammation cytokine genes, immune cells within blood, metabolism of arachidonic acid and amount of cartilage were measured and histopathological variations for knee joint structures were observed. Results: Functions of liver and kidney were not affected. IL-$1{\beta}$ (interleukin-$1{\beta}$), MCP-1 (monocyte chemoattractant protein-1) and TNF-${\alpha}$ (tumor necrosis factor-${\alpha}$) were significantly reduced and IL-6 (interleukin-6) was also reduced but not significantly. After analyzing inflammation cytokine in joints with mRNA (messenger ribonucleic acid), revelation of IL-6, TNF-${\alpha}$, COX-2 (cyclooxygenase-2) and iNOS-II (inducible nitric oxide synthase-II) were all significantly reduced. Revelation of IL-$1{\beta}$ gene was also reduced but not significantly. Neutrophil for WBC (white blood cell) within serum was significantly reduced; monocyte was also reduced but not significantly. PGE2 (prostaglandin E2), TXB2 (thromboxane B2) were significantly reduced and LTB4 (leukotriene B4) was also reduced but not significantly. Destruction of cartilage on micro CT (computed tomography)-arthrography was reduced but had no significant differences. In terms of histopathology, infiltration of inflammation, proliferation of synovial membrane, subsidence of cartilage and bone due to penetration of excessive formation of synovial cell and destruction of cartilage were small (H&E (hematoxylin and eosin), safranine O staining). Conclusions: Based on these results, Jakyakkamchobuja-tang (JKBT) is believed to be useful for suppressing the progress of osteoarthritis and its treatments because of its anti-inflammatory effects and alleviation of pain with histopathological effective efficacy.

Objectives : The aim of the present study is to examine the effect and mechanism of Erycibae Caulis and Corydalis Tuber Pharmacopuncture (ECP) on a mouse model with collagen induced rheumatoid arthritis (CIA). Methods : We evaluated the Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Creatinine, and the Blood urea nitrogen (BUN) of serum to examine the safety of this study. In vivo, we compared the results of the non-treated group, the normal saline pharmacopuncture treated control group, the indomethacin treated group and the ECP group. We evaluated rheumatoid arthritis manifestation and the Rheumatoid Arthritis Index (AI). Also, immune cells in blood affected by ECP were evaluated by calculating the level of white blood cells (WBC), neutrophil, lympocytes and monocytes. Next, the level of Immunoglobulin M (IgM), Immunoglobulin G (IgG), Interleukin (IL)-$1{\beta}$, IL-6, IL-17, Tumor Necrosis Factor (TNF)-${\alpha}$ and Granulocyte-macrophage Stimulating Factor (GM-CSF)in serum were measured. We examined the imaging of cartilage degeneration using micro CT-arthrography of the hind paw. Additionally, we examined the effects of reducing bone volume (BV) ratio and bone surface/bone volume (BS/BV) ratio with 3D Micro-CT. Finally, we did a histopathologic examination analysis. Results : The absence of liver and kidney toxicity was evident. In vivo, edema of the joints of the ECP group decreased greatly in macroscopic observation. AI measurement of the ECP group also decreased significantly compared to the control group. The level of WBC, neutrophil, lympocytes, and monocytes in the blood decreased but there was no statistical significance of this data. IgM of the ECP group decreased significantly compared to the control group. IL-$1{\beta}$, IL-6, TNF-${\alpha}$, and GM-CSF production of the ECP group decreased significantly compared to the control group. As a result of examining joint condition with 3D micro CT, deformation and destruction of the joint was shown to have decreased. Bone density of ECP group increased at a statistically significant level compared to the control group. Degree of joint inflammation of ECP group decreased significantly compared to the control group. After H&E and M-T staining, infiltration of immune cells, subsidence of the cartilage, damage to the synovial cells and joint erosion decreased. Conclusion : This study showed that ECP hindered the process of rheumatoid arthritis and protected joints and cartilage.

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.

In vitro, To evaluate antioxidative effects of BST, total phenolic contents, 1,1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging activity, reactive oxygen species (ROS) levels were measured. Also, to evaluate anti-inflammatory effects of BST treated group, total nitric oxide (NO) and pro-inflammatory cytokines (IL-$1{\beta}$, IL-6, TNF-${\alpha}$) levels were measured in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. In vivo, We injected MIA $50{\mu}l$ (60 mg/ml) into knee joints of rats to induce osteoarthritis. Rats were divided into total 3 groups (normal, control, BST treated group, each n=7). Normal group was not treated at all without inducing osteoarthritis and taken normal diet. Control group was induced osteoarthritis by MIA and taken with 2 ml of distilled water once a day for 4 weeks. BST treated group was induced osteoarthritis by MIA and taken BST 2 ml (200 mg/kg/mouse) once a day for 4 weeks. We evaluated dynamic weight bearing with the Incapacitance Test Meter. At the end of experiment, the rats were sacrificed to observe the functions of liver and kidney, changes of WBC, neutrophil, lymphocyte, monocyte levels in blood, to evaluate the levels of pro-inflammatory cytokines, tissue inhibitor of metallopreteinases-1 (TIMP-1), matrix metalloproteinase-9 (MMP-9), prostaglandin $E_2$ ($PGE_2$), leukotriene $B_4$ ($LTB_4$) within serum. We observed change of articular structures by Hematoxylin & Eosin (H&E), safranin-O staining method and measured amount of cartilage by micro CT-arthrography. Statistical analysis was done by unpaired student's t-test with significance level at p<0.05 in SPSS 11.0 for windows. Results 1. Safety of the BST was identified. 2. AST, ALT, BUN, creatinine levels of BST treated group were within normal limit. In vitro, 1. DPPH and ABTS free radical scavenging activities of BST showed dose-dependent increase. 2. ROS production were significantly decreased. 3. Total nitric oxide (NO) and IL-$1{\beta}$ production were decreased. 4. IL-6 and TNF-${\alpha}$ production were significantly decreased. In vivo, 1. Weight bearing ability was significantly increased. 2. WBC, neutrophil, lymphocyte, monocyte levels in blood were decreased. 3. IL-$1{\beta}$ and TNF-${\alpha}$ levels in serum were significantly decreased. and the IL-6 level was decreased. 4. TIMP-1, MMP-9, $LTB_4$, $PGE_2$ levels in serum were significantly decreased. 5. Cartilage volume of BST treated group was significantly increased. Also changes of cartilage, synovial membrane, fibrous tissue were suppressed. Conclusions The results obtained in this study Bujasasim-tang have effects of antioxidative, anti-inflammatory, relieve pain and protection of cartilage. Therefore we expect that Bujasasim-tang is effective treatment for osteoarthritis.
