Objectives: The purpose of this study was to report the effect of traditional Korean medical therapy such as acupuncture, electroacupuncture and herbal medicine in taste disorder patients. Methods: We surveyed 5 taste disorder patients visiting the Oral Diseases Clinic in the Kyung Hee University Oriental Medicine Hospital from January, 2014 to June, 2014. Before starting traditional Korean medical therapy such as acupuncture, electroacupuncture and herbal medicine, the subjects were evaluated on severity of discomfort using visual analogue scale (VAS), salivary flow rate (SFR), quality of life about oral health (based on the 14-item Oral Health Impact Profile-14) and qi-stagnation condition (based on the 23-item qi-stagnation Questionnaire). Visual analogue scale was re-evaluated during the treatment period. Results: There was no relationship between diminished SFR and severity of discomfort. Also change or loss of taste did not influence the quality of life about oral health. However, stress which refers to qi-stagnation could be one of the reasons taste disorder occurs. After receiving traditional Korean medical therapy, all 5 patients' visual analogue scale score decreased. Conclusions: Traditional Korean medical therapy may potentially be an option for taste disorder. Further evaluations including pre-post comparison with larger number of cases will be needed in the future.

Objectives : This study was designed to investigate the difference between genuine and pseudo halitosis about qi stagnation and stress. Methods : We recruited 63 halitosis patients who visited the halitosis clinic in the Kyung Hee University Korean Medicine Hospital from June 2012 to August 2013. We classified the halitosis patients into two groups, genuine and pseudo halitosis based on organoleptic assesment (OLT) score and evaluated the severity of self-reported halitosis using visual analog scale (VAS), amount of sulfide compounds using Halimeter, qi stagnation level using qi stagnation questionnaire and stress levels using heart rate variability (HRV) parameters. Results : Comparing the genuine halitosis group and the pseudo halitosis group, there was no significant difference in VAS of halitosis but significant difference in halimeter score. Distribution of qi stagnation and non-qi stagnation groups was significantly different between genuine and pseudo halitosis. Compared to the genuine halitosis group, the pseudo halitosis group showed a significant higher value of low frequency/high frequency ratio (LF/HF ratio). Conclusions : The result of this study suggest that there is significant difference about qi stagnation and stress level between genuine halitosis and pseudo halitosis patients, so when approaching pseudo halitosis patients, we should consider their psychological and emotional status.

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.

In this paper we model the liquid crystal director field in the Patterned Vertical Alignment (PVA) LC using the fast Q-tensor method, which can model multidimensional director configurations with defects in the liquid crystal director field. We observed the dynamic behaviors of the defect experimentally by applying the voltage and modeled the LC director field with defect in the active area of the PVA cell. As a result, we could also calculate the optical transmittance.

Objectives : The purpose of this study is to report the effect of moxibustion for paitent with Myelopathy hand Methods : A 65-year-old female patient diagnosed with Cervical myelopathy was treated by moxibustion on both hand and neck, from July 17th to July 29th. The improvement of the patient's Myelopathy hand was evaluated based on JOA(Japanese orthopedic score), VAS(visual analog scale), Grips and release test, Finger escape sign, and DITI(digital infrared thermal imaging). Results : After the treatment of moxibustion, the patient's JOA score were not improved, but VAS, Grips and release test, Finger escape sign and DITI were improved. Conclusions : The result suggests that moxibustion of hand and neck is an effective treatment to Myelopathy hand on Cervical myelopathy. But more cases and researches are needed to evaluate the significancy of moxibustion for Myelopathy hand.

Objectives : To investigate the correlation between DITI and assessment instruments of knee OA. Methods : Data were obtained from 127 subjects with OA of the knee. They were asked to answer VAS pain scale, LFI, WOMAC and KHAQ. Correlation was assessed by examing the pearson's correlation and spearman's rank correlation coefficients. Results : The thermal difference between the patella of knee was correlated with VAS, LFI and WOMAC. Age, duration, BMI and sex were not correlated with the thermal differences of each region. Conclusions : DITI value was useful for evaluating the severity of OA. And we should find out the standardization of analysis of DITI value for diagnosis of OA.

Objectives: The purpose of this study was to evaluate the clinical effect of Korean medical treatments such as herbal medicine, acupuncture, and electroacupuncture by using the portable gas chromatograph OralChroma$^{TM}$ (Abimedical, Japan) in halitosis patients. Methods: We surveyed 30 halitosis patients who had visited the Oral Diseases Clinic in the Korean Medical Hospital of Kyunghee University from October, 2013 to November, 2014. Before starting Korean medical treatment, the subjects were evaluated on sociodemographic characteristics, severity of discomfort using visual analogue scale (VAS), unstimulated salivary flow rate (USFR), and halitosis associated life-quality test (HALT) score. To evaluate the therapeutic effect, we measured the volatile sulfur compounds (VSCs) in breath by using OralChroma$^{TM}$ before and after 3 weeks treatment. Results: The concentration of total VSCs measured by OralChroma$^{TM}$ significantly decreased (p=0.001). Furthermore, the level of hydrogen sulfide and methyl mercaptan also significantly decreased (p<0.05). However, although the level of dimethyl sulfide decreased as well, there was no significance(p>0.05). Conclusions: Korean medical treatment was effective in treating halitosis by decreasing VSCs. Further study, with well-designed randomized controlled trials with larger number of cases will be needed in the future.

Polygoni cuspidati Rhizoma (PCRH) has been used in treatment of menoxenia, skin burn, gallstone, hepatitis, hyperlipidaemia, favus athlete's foot, supperative dermatitis and inflammation. However, its effect in experimental models remains unknown. In this present study, the effect of PCRH for stability on mast cell was analyzed. Two g/kg PCRH inhibited the compound 48/80-induced anaphylaxis by 75%. In addition, PCRH inhibited the tumor necrosis factor-$\alpha$ and interleukin-8 secretion as compared with the phorbol 12-myristate 13-acetate plus calcium ionophore A23187 stimulated human mast cell line, HMC-1 cells. These results suggested PCRH may inhibit mast cell-mediated anaphylactic reaction.

Penetrating neck injuries constitute 5-10% of all trauma cases. These injuries may cause life-threatening suppurative or vascular complications, but the severity and extent of damage depends upon the inflicting object and the involved structures. If significant complications are not expected, then it is best to leave the foreign body embedded and avoid surgical risks. We present a rare case of a foreign body embedded in the neck causing tinnitus and foreign body sensation.
