Objectives : Burning mouth syndrome (BMS) is characterized by chronic pain or a burning sensation in the mouth. There is limited evidence available to provide clear guidelines for treating BMS patients and a variety of different treatments have been used. This study was designed to investigate the Effects of Korean medicine therapies on oral pain in patients with BMS. Methods : We surveyed 30 BMS patients who newly visited the Oral Diseases Clinic in the Kyung Hee University Korean Medicine Hospital from February 2012 to March 2013. When the patients visited the clinic for the first time, they were evaluated on sociodemographic characteristics, BMS questionnaire, severity of pain using visual analogue scale (VAS) and pressure pain threshold (PPT) of the acupuncture point CV17. After 3 weeks of Korean medicine therapies (acupuncture, electroacupuncture, pharmacopuncture and herbal medicine), they were re-evaluated with the VAS and the PPT. Results : After 3 weeks of Korean medicine therapies, 30 patients' oral pain improved and the PPT score on CV17 rose, which means decrease of qi-stagnation score. Conclusions : Korean medicine therapies were effective on oral pain in patients with BMS. To confirm the additional curative effect and evaluate the efficacy of each treatment, well-designed randomized controlled trials will be needed in the future.

Background and Objective: The Korean agricultural population is now rapidly aging. Older people in rural areas are weak due to work-related musculoskeletal disorders. The aim of this case is to report treatment of injuries to the nerves at the wrist and hand level by Korean medicine. Methods: The patient in this case was a 74-year-old male. He had injured nerves at the right wrist and hand level due to agriculture work. We treated him with acupuncture, herbal medicine, etc. Results: The patient showed the first sign of recovery of his wrist after 13 days treatment. After 37 days of treatment, his wrist movement was restored to a nearly normal range. He showed the first sign of recovery in a finger after 19 days of treatment and his grasping power increased from 0% to 60%. The cold sensation in his hand and arm also disappeared. Conclusions: We cannot generalize based only on this one case study. Nevertheless, this report suggests that Korean medicine may be an effective treatment for injury of nerves at the wrist and hand level.

The recent increased interest in hygiene has led to the use of a variety of detergents everyday life. Accordingly, accidents occur frequently, but proper precautions or treatments have not yet been established for these occasions. The patient in this case had accidentally ingested basic detergent, after mistaking it for a drink. This had caused acid reflux swallowing distress. Treatment in a western medical hospital had resulted in improvement in inflammation, as observed with an esophageal endoscopy test, but the patient still found it almost impossible to drink or eat. Following treatment with herbal medicine and acupuncture, the patient’s food intake increased and the pain and dysphagia were diminished. We cannot generalize based only on this one case study, so further studies are needed.

Tanning ability is important, because it represents the ability of the skin to protect itself against ultraviolet (UV) radiation. Here, we sought to determine genetic regions associated with tanning ability. Skin pigmentation was measured at the outer forearm and buttock areas to represent facultative and constitutive skin color, respectively. In our study population consisting of isolated Mongolian subjects, with common histories of environmental UV exposure during their nomadic life, facultative skin color adjusted by constitutive skin color was used to indicate tanning ability. Through linkage analysis and family-based association tests of 345 Mongolian subjects, we identified 2 potential linkage regions regulating tanning ability on 5q35.3 and 12q13.2, having 6 and 7 significant single nucleotide polymorphisms (SNPs), respectively. Those significant SNPs were located in or adjacent to potential candidate genes related to tanning ability: GRM6, ATF1, WNT1, and SILV/Pmel17.

Objectives : Hwangyeonhaedok-tang(HHDT) has been traditionally used for various clinical symptoms associated with gastrointestinal disorder, cardiovascular diseases, and inflammation in the Oriental medicine. However, little is known for antioxidant and anti-inflammatory effects of HHDT on dextran-sulfate sodium(DSS)-induced colitis in mice. Methods : In this study, we investigated an antioxidant and anti-inflammatory effects of HHDT on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. HHDT was orally administrated the various concentrations(25-100 mg/kg, body weight/day) for 7 days with one time per day. Results : HHDT reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, disease activity index(DAI), and histological colon injury. HHDT also inhibited significantly serum NO and prostaglandine $E_2(PGE_2)$ productions in DSS-induced colitis mice. Furthermore, HDDT increased significantly an superoxide anion(SOD), catalase, and glutathione peroxidase(GPx) activity of the colon tissue in DSS-induced colitis mice. Conclusions : These results suggest that HHDT administration could reduce significantly the clinical signs and inflammatory mediators, and increase antioxidant activity in DSS-induced colitis model mice and is a good candidate for further evaluation as an effective anti-ulcerative agent.

Silicon carbide(SiC) layer is particularly important tri-isotropic (TRISO) coating layers because it acts as a miniature pressure vessel and a diffusion barrier to gaseous and metallic fission products in the TRISO coated particle. The high temperature deposition of SiC layer normally performed at $1500-1650^{\circ}C$ has a negative effect on the property of IPyC layer by increasing its anisotropy. To investigate the feasibility of lower temperature SiC deposition, the influence of deposition temperature on the property of SiC layer are examined in this study. While the SiC layer coated at $1500^{\circ}C$ obtains nearly stoichiometric composition, the composition of the SiC layer coated at $1300-1400^{\circ}C$ shows discrepancy from stoichiometric ratio(1:1). $3-7{\mu}m$ grain size of SiC layer coated at $1500^{\circ}C$ is decreased to sub-micrometer (< $1{\mu}m$) $-2{\mu}m$ grain size when coated at $1400^{\circ}C$, and further decreased to nano grain size when coated at $1300-1350^{\circ}C$. Moreover, the high density of SiC layer (${\geq}3.19g/cm^3$) which is easily obtained at $1500^{\circ}C$ coating is difficult to achieve at lower temperature owing to nano size pores. the density is remarkably decreased with decreasing SiC deposition temperature.

Dirofilaria immitis infection is one of the most important parasitic diseases in dogs and public health. It often elicits nodules in the pulmonary parenchyma and in the subcutaneous tissues of human. In this study, we investigated the prevalence of D. immitis infection among 754 dogs in Seoul area from April to December 2012. The infection rate of 754 dogs was 9.8% (74/754) by the antigen test (canine SNAP 4Dx). The infection rates of D. immitis in dogs at the age of < 2, 2~4, 5~7, 8~10, and > 10 years were 3.7% (7/189), 12.9% (30/233), 15.0% (19/127), 9.8% (18/184), and 0% (0/21), respectively. The infection rates in the female and male dogs were 9.7% (33/340) and 9.9% (41/414), respectively. The regional infection rates in northern and southern Han river region of Seoul were 10.7% (44/410) and 8.7% (30/344), respectively. In order to confirm D. immitis infection, we performed PCR on serum samples of 74 dogs which tested positive for D. immitis antigen by the antigen test and we detected a specific gene ITS-2 in 59 serum samples. In conclusion, this study suggests that treatment and preventive care on the D. immitis infection should be considered in dogs of Seoul area.

Purpose: Developmental delay and mental retardation are frequently occurring disorders that present major socio-economic burden on the affected individual's family and society. Both can be congenital or acquired. However, a large number of people are institutionalized without exact diagnosis and, as a result, have not received proper care. Methods: 508 subjects with mental retardation or developmental delay from six institutions in Chung Buk Province were clinically evaluated and screened for metabolic and endocrinologic problems between 2000 and 2012. Results: Clinical genetic disorders were observed in 52 (10.2%) subjects. Cerebral palsy attributed to 21% of the institutionalized. 18 (3.5%) were diagnosed with metabolic disorders and 13 (2.6%) exhibited secondary endocrinologic dysfunction. Over 16% showed metabolic evidence of malnutrition. Conclusion: 21% and 3.5% of the population institutionalized due to mental retardation or developmental delay were afflicted by preventable cerebral palsy and metabolic disorders, respectively. Through early identification of the causes and early treatment, it may be possible to prevent, reduce, or alleviate the disability of many institutionalized individuals. Further research is imperative for establishing guidelines for diagnostic investigation for mental retardation.
