  • Objective: The aim of this study was to identify the efficacy and underlying mechanism of cloves as an osteoarthritis (OA) treatment in a monosodium iodoacetate (MIA)-induced rat OA model. Osteoarthritis (OA) is nowadays one of the most prevalent degenerative joint diseases. Methods: Sprague-Dawley rats treated with MIA (50 μL; 80 mg/mL) were used as in vivo OA models. Cloves (100 and 200 mg/kg b.w.) were administered orally once daily for 2 weeks from 7 days after MIA injection. Changes in hindpaw weight distribution (HWD) were measured as a joint discomfort index. Activation markers related to inflammatory responses and cartilage degeneration in the right knee joints were evaluated by serum analysis and western blotting. Results: HWD decreased in the MIA control group but showed a dose-dependent elevation after clove treatment. Clove treatment inhibited inflammatory factors by PI3K/Akt/NF-κB signaling pathways, while also activating antioxidant factors through Sirt1/AMPK signaling pathways. Clove treatment also suppressed matrix metalloproteinase (MMP) overexpression and significantly increased the levels of tissue inhibitors of metalloproteinases (TIMPs). Conclusions: Treatment with cloves effectively reversed MIA-induced effects. Therefore, clove treatment could have the potential to protect against or treat OA.

  • Halicephalobus gingivalis is a free-living nematode that occasionally causes infections in horses. We report a rare case of limb fracture of horse caused by infection with H. gingivalis. An 8-year-old mare was referred to the Veterinary Hospital of the Federal University of Lavras with claudication grade 5 of the right hind limb, that had been started 3 months ago. The patient had aseptic arthritis in the tarsal joint and edema that extended to the quartile. The radiographic examination showed punctate osteolysis with exacerbation of bone trabeculation along the calcaneus, talus, proximal epiphysis of the third metatarsal and distal epiphysis of the tibia. Treatment for arthritis was initiated, and the animal showed a slight improvement in limb function. However, 21 days after hospitalization, due to a comminuted fracture of the tibia, it was euthanized. At necropsy, yellowish masses were found from the metatarsal to the tibia, and around the tarsal bones and joint. Similar masses were also found in the left kidney. Numerous nematodes compatible with H. gingivalis were identified. This is the first description of a pathological fracture caused by H. gingivalis infection in an equine limb.

  • This study was undertaken to verify various relations between dental health belief and related behaviors in mothers and children. Data for this study were obtained by 264 pairs of 1st and 3rd grade elementary school children and their mothers by self developed questionnaire, The questionnaires are made on the general socio-economical characteristics, the oral health knowledge and the behaviors relative to the oral health and oral health education as to how mothers implement the oral health related activities for their children, while for the children, the questionnaires have been measured relative to the oral health beliefs and health behaviors for the children. The obtained results have shown that mothers become with more ages, the usefulness to prevent children's oral diseases becomes lower, and as much as mothers have higher education level, the sensitivity relative to the oral diseases has been measured low. To the degree that the students live well in economical respect, it has been found that they placed more importance on the oral health. As much as the number of mothers tooth brushing becomes made more in a day, the tooth brushing of the children becomes more that much, and also has higher level of oral health beliefs. The number of children to see dentists has been found high, and to the extent of increasing frequency of visiting dental clinics. As the number of mothers tooth brushing education becomes made more frequent for the children. Also, as mothers put more restriction on the sugar intakes by the children, they placed higher importance on the oral health for their children. In conclusion oral health behavior in mothers' influence on dental health belief of their children, it has been reviewed necessary to activate more the mother-children joint oral health education and oral health projects that mothers and children take part together, as well as to study more in accurate and systematic approaches through more comprehensive and various subjects and elements further in the future.

  • This paper researches the features of blood stasis theory of Wangqingren, who wrote 『Yilingaicuo』 that greatly contributed in the development of blood stasis theory at Qing dynasty period. And the disease cause, disease mechanism of blood stasis and scope of modern diseases related with blood stasis are studied by research on clinical papers which used 33 prescriptions in 『Yilingaicuo』 in modern times. Research on the features of blood stasis theory of Wangqingren is proceeded by referring to the annotations of 『Yilingaicuopingyi』 and the papers which related with blood stasis from Korea and China. And clinical papers are searched in China Academic Journals(CAJ) of China National Knowledge Infrastructure(CNKI) to analyse the scope of modern diseases related with blood stasis. The features of blood stasis theory in 『Yilingaicuo』 expanded the range of existing theory. Wangqingren thought that chronic disease, weird disease, the disease of no effect from normal treatments were related with blood stasis. And he attached great importance to qi and blood and thought that the main pathogenesis of blood stasis was qi deficiency. And a lot of Astragalus membranaceus Bunge were combined in many prescriptions to reinforce qi. He also used different herbs according to the location of the disease. Musk and Allium fistulosum were used for the disease located at head or upper part of the patient's trunk. Bupleurum falcatum L., Aurantii Fructus Pericarpium and Platycodon grandiflorum A. De Candolle were used for the disease located at thorax. Cyperus rotundus L., Linderae Radix and Aurantii Fructus Pericarpium were used for the disease located at the stomach or below the costal angle. Foeniculi Fructus and Corydalis remota were used for the disease located at belly or lower part of the patient's trunk. Trogopterorum Faeces, myrrha, Cyperus rotundus L. and Cnidium officinale were used for the disease located at extremity or joint.

  • Nowadays many neurological diseases such as stroke and Parkinson diseases are continually increasing. Orthotic devices as well as exoskeletons have been widely developed for supporting movement assistance and therapy of patients. Robotic knee orthosis can compensate stiff-knee gait of the paralyzed limb and can provide patients consistent assistance at wearable environments. With keeping a robotic orthosis wearable, however, it is not easy to develop a compact and safe actuator with fast rotation and high torque for consistent supports of patients during walking. In this paper, we propose a novel kinematic model for a robotic knee orthosis to drive a knee joint with independent actuation during swing and stance phases, which can allow an actuator with fast rotation to control swing motions and an actuator with high torque to control stance motions, respectively. The suggested kinematic model is composed of a hamstring device with a slide-crank mechanism, a quadriceps device with five-bar/six-bar links, and a patella device for knee covering. The quadriceps device operates in five-bar links with 2-dof motions during swing phase and is changed to six-bar links during stance phase by the contact motion to the patella device. The hamstring device operates in a slider-crank mechanism for entire gait cycle. The kinematics and velocity/force relations are analyzed for the quadriceps and hamstring devices. Finally, the adequate actuators for the suggested kinematic model are designed based on normal gait requirements. The suggested kinematic model will allow a robotic knee orthosis to use compact and light actuators with full support during walking.

  • Purpose: Pain or discomfort caused by foot diseases may lead to abnormal gait, resulting in decreased bone mineral density (BMD) of the affected lower limb. We analyzed the effect of foot affection to BMD and its clinical significance. Materials and Methods: Bilateral hip BMD was evaluated in 93 patients with unilateral chronic foot disease. To minimize statistical errors, we excluded patients with medical histories that had influence on BMD. Analysis was based on the results of BMD tests at the first visit. All patients denied past medical intervention for osteoporosis. The difference in density between bilateral limbs was determined by comparing BMDs of the neck, upper neck, trochanter and total area of hip. Results: Test results revealed the decrease of BMD in the lower limb with the affected foot, compared to the unaffected side. This decrease was significant in the area of the trochanter (p <0.05). There was no marked difference of BMD in relation with duration of affection, underlying disease or age. Pertaining the location of foot affection, the hindfoot group showed significant decrease in BMD compared to the forefoot group. The group with affection in bone and joint also showed a marked decrease in BMD compared to the soft tissue group (p <0.05). Conclusion: Pain and discomfort caused by chronic foot diseases can lead to a decrease in the BMD of the affected lower limb. This may increase the risk of complications such as osteoporotic fracture and muscular atrophy.

  • PURPOSE: The aim of this study was to measure changes in spine inclination and thoracolumbar structure and morphology according to upper-extremity movements with and without resistance in order to evaluate the spine stability in workers. METHODS: Forty-eight middle-aged male workers (mean age, 40.48 ± 6.27 years) participated in this study. Using the spine analysis system, changes in the inclination of the spine and structure as well as shape of the thoracolumbar spine were measured. For posture measurement, the postures of standing, lifting the right and left arms (shoulder joint 90° flexion), and lifting with both arms were measured in random order. In addition, variables were measured using a resistance of 3 kg for each posture. The statistical significance level was set at α = .05 for all variables. RESULTS: There were statistically significant differences between the front and back inclinations of the spine, kyphotic curve of the thoracic spine, lordotic curve of the lumbar spine, rotation changes in the thoracolumbar spine, and rotation changes in the T4 vertebra (p < .05). However, there was no significant difference in the left and right tilts of the spine. In the post-hoc analysis, rotation changes in the T4 vertebra showed a significant difference in posture when resistance was applied to the left and right sides CONCLUSION: Causes of musculoskeletal diseases include excessive thoracic spine rotation, torsion, and hyperlordosis of the lumbar spine. Therefore, it is necessary to improve the working environment in order to ensure a healthy posture and prevent musculoskeletal diseases that can reduce the ability to carry various and/or excessive loads.

  • Objectives : To investigate the progress, characteristics, and reasons of CV12 moxibustion that King Sukjong of Joseon Dynasty had experienced 31 years since 1684. Methods : This study mainly extracted the records and related records about CV12 moxibustion of King Sukjong and relevant records from Seungjeongwon Ilgi, and analyzed them. Aside from that, medical books wrote at that time and relevant records were additionally investigated. Results : King Sukjong cauterized CV12 or other CV12 related acupoints with moxa 21 years out of his 31 years from 1684 to 1714. The cautery period was usually between late January and mid February. He had 100 pieces of moxa for cautery. On the last day of his moxibustion, he cauterized ST36 with moxa. The moxibustion process consisted of the following steps: suggestion or requirement of moxibustion, decision of date and time, and moxa cautery. In 1684, the reason why King Sukjong cauterized CV12 with moxa was to treat his joint pain and nauseous symptoms. The effect can be found in Donguibogam, many other Korean medical books, and other general books at that time. In 1685, he began to cauterize CV12 with moxa to prevent diseases. Since then, most moxa cautery on CV12 had been performed in the same context. Conclusions : For 21 years, King Sukjong repeatedly cauterized CV12 with moxa. The moxa therapy was conducted to prevent diseases mostly. And King Sukjong had a lot of interest in the therapy. For the reasons, the therapy had repeatedly been performed so long.
