Purpose: This study examined the application of electric stimulation to the auricle acupoint (frequency 2 Hz, stimulation level: noxious) with 30 elderly people over 65 years that received treatment in a rural hospital to determine the influence of pain, gait and balance in the aged with knee joint disease. Methods: The subjects were divided into three groups; the degenerative joint diseases (DJD) group (1 male, 9 females), the total knee replacement (TKR) group (1 male, 9 females) and the control group (1 male, 9 females). Auricualr electrical stimulation (AES) was applied with low frequency, high intensity transcutaneous electrical nerve stimulation for 10 seconds per each point. Results: 1. For the change of pain according to AES, there was interaction in the resting period (p<0.001) and gait (p<0.001) and pain of the DJD group and TKR group was decreased. 2. The range of motion (ROM) of the knee joint showed a significant difference in interaction for each group of elderly people (p<0.001) and the ROM for the DJD group and TKR group of elderly people was increased. 3. In the analysis of gait speed changes, there was a significant difference in interaction for each group of elderly people (p<0.001) and for gait speed in the DJD group and TKR group of elderly people. 4. It was found in the change of static balance that there was a significant difference in interaction for each group of elderly people (p<0.01) and balance capacity in the DJD group and TKR group of elderly people was increased. Conclusion: The aged with knee joint disease have pain, and a decreased function of gait and balance. AES was an excellent treatment for control of pain, and an excellent treatment to enhanced joint functions. AES was useful for improving gait and balance due to decreased pain.

Background and Purpose : Now, a lot of people are suffering from arthritis of knee joint. Western and oriental medicine, all of them are trying various methods to cure this disease, but generally the grade or level of repairing has been decided by the subjective estimation of the patients and doctors. So, we suggest the new standard for estimating the level of repair in this disease using nuclear medicine. Objective : To evalute the difference of the blood pool and delayed images in the correlation with clinical symptoms in patients with arthritis of knee joint by using acupuncture. Methods : Eight patients with arthritis of knee joint included in this study. Using Thermograph (D.I.T.I) and Radionuclide, we obtained the results. In Bone scan Tc-99m MDP, and MIBI scan was obtained at 1 minute and 3 hour after injection of 1,110 MBq Tc-99m MDP and MIBI. The analysis was carried out hurted area of joint. The Joint-to-background(J/B) ratios were obtained exclusively in the joints regions. Clinical symptoms were evaluated as pain and swelling graded from 0(no) to 5(severe) in the same joints, respectively. Results : J/B ratios on the delayed scans were higher than those on blood pool images. There was significant correlation between clinical symptoms and J/B on blood pool image in the joints =0.03). Conclusion : The results demonstrate that blood pool images of Tc-99m MDP scintigraphy correlates with clinical symptoms more than delayed images in patients with arthritis Joint.

Osteoarthritis(OA) is a degenerative joint disease characterized by fibrillation and erosion in cartilage tissue, chondrocyte proliferation and osteophyte formation at the joint margins, and sclerotis of subchondral bone. We investigated the effects of Acyranthes Radix administration and Cervi Cornu Parvum aqua-acupuncture in monosodium iodoacetate(MIA) induced experimental osteoarthritis model. Sprague-Dawley 60 rats of 7-8 weeks, weight $240{\pm}10\;g$ were divided into two groups including the sham operation group(15 rats) and ostoarthritis group(45 rats). Histopathological examination, Mankin's score, and the measurement of inflammation factor were performed. Histological findings that are similar to those observed in human osteoarthritis, such as disorganization of chondrocytes, erosion and fibrillation of cartilage surface, and subchondral bone exposure were observed in a MIA-induced osteoarthritis model. Saflanin-O fast green staining revealed that marked diffuse reduction of proteoglycans treated with MIA. The Mankin's score were closely correlated to the grade of histological findings. The level of prostaglandin E2 and C-reactive protein were decreased experimental groups. We conclude that Acyranthes Radix administration and Cervi Cornu Parvum aqua-acupuncture, and combination treatment exerts a beneficial influence on the cartilage lesion in osteoarthritis rat.

Temporomandibular joint disorders (TMD) often show muscular disorder, internal derangement and degenerative change of articular surface of the condyle. It is important to choose adequate diagnostic method for obtaining data for the diagnosis and treatment. Magnetic Resonance Imaging (MRI) has some advantages, because it shows good resolution image for the soft tissue and it is not invasive to the human body. We have performed serial research about the retrodiscal tissue of the TMJ according to the progress of the disease, using T2 weighted image, since 2002. In this study, we applicated resized observation area to compare signal intensity between the retrodiscal tissue of the TMJ and cerebral gray matter, using T2 weighted image.

Background: The purpose of this study is to compare axis change during cervical flexion and extension according to lordosis angle to patients with scoliosis. Methods: Movement axis change was estimated during cervical flexion and extension in twenty-four scoliosis patients with hypolordosis using radiography. Subjects were divided into mild lordotic curve group (MLCG, n=12, $34{\sim}25^{\circ}$) and severe lordotic curve group (SLCG, n=12, less $25^{\circ}$) according to cervical lordosis angle. Results: During cervical flexion, both group showed movement axis change to upper part of cervical vertebra and SLCG showed greater than MLCG but there is no significant difference. During cervical extension, SLCG showed greater than MLCG and there is significant difference. Conclusion: It is considered that cervical hypolordosis acts as important factor to scoliosis and degenerative joint disease because it leads to change of movement axis and central route of joint.

Osteoarthritis (OA) is an inflammatory degenerative joint disease that is accompanied by irreversible joint cartilage destruction. Recently, the antioxidant effects of Carpomitra costata, which is a type of brown algae, have been reported, but their effects on OA have not been investigated. In this study, the anti-osteoarthritic effect of the ethanol extract of C. costata (EECC) on SW1353 human chondrocytes was studied. Results showed that EECC significantly attenuated the interleukin-1β (IL-1β)-induced release of pro-inflammatory mediators, including prostaglandin E2 and nitric oxide (NO), as well as expressions of cyclo-oxygenase-2 and inducible NO synthase. EECC also inhibited the IL-1β-induced expressions of matrix metalloproteinase-1, -3, and -13 in SW1353 chondrocytes, which reduced their extracellular secretion. In addition, the oxidative stress induced by IL-1β was confirmed to be blocked by EECC due to the inhibition of reactive oxygen species generation. Moreover, EECC suppressed IL-1β-mediated translocation of nuclear factor-kappa B (NF-κB) from cytosol into the nucleus and the degradation of IκB-α, which indicates that EECC exhibits anti-inflammatory effects by inhibiting the NF-κB signaling pathway. These results are the first to demonstrate the anti-inflammatory activities of C. costata extracts in chondrocytes, thus suggesting that this algae extract may be used in the treatment of OA.
