The effects of fermented Achyranthes japonica Nakai, Angelica gigas Nakai, and Eucommia ulmoides Oliver extracts (FAAE) on regulation of inflammation and apoptosis were investigated in primary cultured rat cartilage cells. To identify the protective effects of FAAE against H₂O₂, cell survival was measured by MTT assay. Smad3, Collagen type I, MMP3, and MMP13 were measured by real-timpe PCR and westernbot and the inflammatory (NF-κB pathway, COX-2, iNOS) factors were determined by western blot. The apoptosis related factors (JNK, c-Fos, c-Jun, caspase 3, Bax, and Bcl-2) were determined by western blot. FAAE significantly increased the follwing: H₂O₂ treated cell survival, mRNA and protein expression of Smad 3, collagen type I. In addition, FAAE significantly decreased the protein expression of inflammatory and apoptosis related factors. This study suggests that FAAE have a protection effect of chondrocytes through inhibition of inflammation and apoptosis. Thus, FAAE is a therapeutic potential food componet in osteoarthritis.

Purpose: To evaluate the clinical results after microfracture surgery for full-thickness chondral lesion of the knee. Materials and Methods: Thrity-seven patients, who had underwent microfracture surgery for full-thickness chondral lesion of the knee between January 1999 and December 2005, were reviewed. Their mean age at the time of operation was 31 years (range, 21~38 years) and mean follow up period was 2.7 years. All patients were reviewd every 6 months after operation. Clinical outcomes were evaluated by activity of daily living (ADL), Tegner activity scale, International Knee Documentation Committee (IKDC) knee examination form, Lysholm score and satisfaction of treatment. Results: ADL and Tegner activity score improved in 83% of patients during first 18 months, but decreased during next 6months. IKDC score improved from 58 points at operation time to 86 points after 12 months, but decreased to 79 points and 68 points at 18 and 24 months after operation, respectively. Also, Lysholm score improved from 61 points at operation time to 89 points after 12 months, to 92 points after 18 months, but 73 points after 24 months. At the last follow-up, 22 patients were excellent or good in satisfaction of treatment, whereas 12 patients were fair, 3 patients were poor. Conclusion: Microfracture surgery for full-thickness chondral lesion of the knee has a good functional improvement for first 12 months after operation, but its effectiveness has decreased over time.

We investigated the effects of oyster shell extract (OSE) on papain-induced osteoarthritis in C57BL/6J mice. Osteoarthritis was induced in mice by a papain injection into the knee joint. The mice were divided into a total of five groups (n=8). The normal group was untreated, whereas the papain group (negative control) was induced with osteoarthritis and treated with water daily. The papain+DS group (positive control) was treated with diclofenac sodium. Papain+OSE groups were treated with OSE concentrations of 100 and 200 mg/kg/bw for 20 days. Proteoglycan content in articular cartilage was analyzed through safranine-O fast green staining and H&E staining. The histopathological changes in cartilage were measured by the Rudolphi score approach. The contents of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin (IL)-$1{\beta}$, and IL-6 in plasma were analyzed by the ELISA method. After experiments, body weights of the treated groups were not significantly different compared with the normal group. Cartilage loss and joint instability significantly improved in a dose-dependent manner in the OSE-treated group compared with the papain group (P<0.05). Proteoglycan content was significantly higher in the OSE-treated group than the papain group (P<0.05). Osteoarthritis scores of the OSE-treated group were significantly decreased compared with the papain group (P<0.05). TNF-${\alpha}$, IL-$1{\beta}$, and IL-6 content in the plasma of the papain+OSE treated groups significantly decreased in a dose-dependent manner compared with the papain group (P<0.05). These results suggest that OSE treatment might have anti-arthritic effects on papain-induced osteoarthritis in C57BL/6J mice.

Schisandrae Fructus (SF), the fruit of Schisandra chinensis (Turcz.) Baill., is widely used in traditional medicine for the treatment of a number of chronic diseases. SF extracts have been recently reported to attenuate the inflammatory responses in SW1353 human chondrocyte cells in in vitro and monosodium iodoacetate (MIA)-induced cartilage degradation in in vivo osteoarthritis (OA) models. However, their protective and therapeutic potentials against OA in primary culture chondrocytes and animal models remain unclear. Therefore, we investigated the effects of the ethanol extract of SF on the activity of matrix metalloproteinases (MMPs), biomarkers for diagnosis of OA, on interleukin $(IL)-1{\beta}-induced$ primary cultured rat cartilage chondrocytes and MIA-induced osteoarthritis in a rat model. Our data indicated that SF treatment significantly reduced the mRNA expression and enzyme activity of MMP-1, -3 and -13 in $IL-1{\beta}-induced$ primary cultured rat cartilage chondrocytes. The chondro-protective effects of SF were then analyzed in a rat OA model using a single intra-articular injection of MIA in the right knee joint. According to our results, the elevated levels of MMP-1 and -3 were markedly ameliorated by SF administration. Collectively, these findings indicate that SF could be a candidate for the treatment of OA.

The purpose of this study was to assess the effects of High-Voltage Pulsed Current (HVPC) and ultrasound on adjuvant-induced arthritis in rats. Adjuvant arthritis was induced in female Sprauge-Dawley rats by the subcutaneous injection of a single dose of $.1m{\ell}$ of Complete Freund's Adjuvant (CFA) (1 mg of Mycobacterium Butyricum suspended in $.1m{\ell}$ paraffin oil) into the right hind paw. A randomized, parallel-groups design of 24 subjects was used. All rats were randomly assigned to control (n=8), ultrasound (n=8), and HVPC (n=8) were compared with those of injured rats. The rats in the pulsed ultrasound group were treated at 1 MHz frequency with $.5W/cm^2$ intensity in 1:4 mode for 5 minutes per day. The rats in the HVPC group were treated at 120 pulses per second and $50{\mu}s$ phase duration, 20 mA intensity for 30 min per day. Treatment was done in the left and right hind limb for 2 weeks. We evaluated clinical, radiographic, hematologic and histopathologic findings before and after treatment and obtained the following results. 1. Edema of the right hind paw was more significantly reduced in the ultrasound and HVPC groups than the control group on days 9, 12, and 14 (p<.05). Edema of the left hind paw was more significantly reduced in ultrasound and HVPC groups than the control group on days 12, 14 (p<.05). 2. WBC counts of the ultrasound and HVPC groups as compared with the control group were becoming remarkably decreased after the treatment. 3. In radiologic findings, arthritis formation was seen according to the score of arthritis, which was the highest in the control group, upon the observation of radiographs of the left and right hind paws. However, no statistically significant difference was present in the score within three groups. 4. In the histopathologic findings, ultrasound and HVPC groups had effectively suppressed erosions of articular cartilage and inflammatory cell infiltrations. Therefore, the results of the study show that rats that were treated with the ultrasound and HVPC effectively suppressed adjuvant arthritis. However, no statistically significant difference was present between the ultrasound group and the HVPC group.

Purpose: The purpose of this study is to induce artificial arthritis on rabbit TMJ by injecting collagenase. Materials and Methods: An experimental animal model of arthritis induced by surgical method or intraarticular injection of chemical agent like LDH, papain, ketorolac. Surgical method is complex and needs a long time in inducing arthritis. Intra-articular injection of chemical agent like LDH, papain, ketorolac is simple. But chemical agent like LDH, papain, ketololac needs multiple injections to induce arthritis and mechanism inducing arthritis was known. Collagenase destroys helical domain of type II collagen in extracellular matrix produced by chondrocyte and then induces arthritis. We injected collagenase (0.5, 1.0, 2.0 mg) into the temporomandibular joint of rabbit. In the control group saline was intra-articularly injected. The condylar cartilage, disk and synovia were histologically examined at 1, 2, 4, 6 weeks after the initiation of collagenase injections. Results: Four weeks after injection of 2.0 mg collagenase, we could see histologic change like arthritis. In other groups, we couldn't see arthritis-like change. Conclusion: In our study, we produce arthritis on temporomandibular joint of rabbit by using injection of collagenase in temporomandibular joint of rabbit. And this experimental osteoarthritis is a useful animal model.

Thirty rabbits underwent femoral lengthening using monolateral external fixator to evaluate results and complications of limb lengthening. Twenty rabbits survived until consolidation of callus formed at the lengthening site after finishing lengthening. Ten rabbits were sacrificed during femoral lengthening because of complications. Survived 20 rabbits were classified to two groups according the amount of lengthening: group I (10% lengthening of the femoral length); group II (20% lengthening). There was no significant difference of consolidation time between two groups (p=0.25). Varus angulation at the lengthening site occurred in 60% of two groups and the amount of varus angulation in group II was larger than that of group I. Degenerative change of articular cartilage at the medial condyle of the distal femur was found in 30% of group II. Of sacrificed ten rabbits, 5 had pin loosenings with pull an of pins from the femur, 2 had fermoral fractures around the pin-tract site, and 3 had severe osteomyelitis of the femur around the pin-tract site.
