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.

Brugmansia arborea L. (Solanaceae), commonly known as "angel's trumpet," is widely grown in North America, Africa, Australia, and Asia. It has been mainly used for ornamental purposes as well as analgesic, anti-rheumatic, vulnerary, decongestant, and anti-spasmodic materials. B. arborea is also reported to show anti-cholinergic activity, for which many alkaloids were reported to be principally responsible. However, to the best of our knowledge, a phytochemical study of B. arborea flowers has not yet been performed. Four flavonol glycosides (1-4) and one dihydroflavanol (5) were for the first time isolated from B. arborea flowers in this study. The flavonoids showed significant antioxidant capacities, suppressed nitric oxide production in lipopolysaccharide (LPS)-treated RAW 264.7 cells, and reduced inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) protein production increased by LPS treatment. The contents of compounds 1-4 in n-BuOH fraction were determined to be 3.8 ± 0.9%, 2.2 ± 0.5%, 20.3 ± 1.1%, and 2.3 ± 0.4%, respectively, and that of compound 5 in EtOAc fraction was determined to be 12.7 ± 0.7%, by HPLC experiment. These results suggest that flavonol glycosides (1-4) and dihydroflavanol (5) can serve as index components of B. arborea flowers in standardizing anti-inflammatory materials.

Objective : Hemophilia, a genetically determined disorder, is characterized by abnormality of the coagulation mechanism due to functional deficiency of a specific factor, namely VIII or IX. In this study, the effect of Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was evaluated. Methods : We treated him with acupuncture by stimulating Dong-Si acupuncture point(Yuk Wan) and assessed the effect by using manual dynamic evaluation of MRC(Medical Research Council) and Modified Barthel Index. Results : After treatment, the bleeding tendency was grossly reduced and bleeding lesion was absorbed gradually. And manual dynamic evaluation of the upper extremity increased from 4 grade to 5 grade. Conclusions : This result suggest that Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was effective. And futher studies are required to concretely prove the effectiveness of Dong-Si acupuncture therapy for treating hemorrhagic diseases.

Purpose: This study evaluated the postoperative stability of counter clockwise rotation of the mandibular plane in anterior openbite patients, who have had one jaw surgery performed. Methods: This study includes patients with skeletal class III malocclusion accompanied by anterior openbite among the patients who have had BSSRO performed, resulting in counter clockwise rotation of the mandibule. We excluded the patients with genioplasty and segmental surgery, and included 23 patients who underwent BSSRO. Results: We found no statistical significance between the amount of counter clockwise rotation in the mandible in the Pearson correlation test. Also, there was no significant difference between Group 1 (< $3^{\circ}$) and Group 2 (> $3^{\circ}$). Conclusion: This study evaluated the amount of horizontal relapse, and the degree of relapse. Stable results were obtained. Although there was no statistical significance between the degree of openbite and the amount of horizontal relapse, the group with a greater amount of openbite had a greater amount of relapse.

The fresh ginseng roots were extracted with aqueous methanol, and the obtained extracts were partitioned using ethyl acetate, n-butanol, and water, successively. The repeated silica gel and octadecyl silica gel column chromatogaraphy for n-butanol fraction afforded four diol ginseng saponins, ginsenosides $Rb_1$, $Rb_2$, $R_c$, and Rd. The physicochemical, spectroscopic, and chromatographic characteristics of these ginsenosides were measured and compared with those reported in the literature. Some of the peak assignments in previously published $^1H$- and $^{13}C$-nuclear magnetic resonance (NMR) spectra were inaccurate. This study employed two-dimensional NMR experiments, including $^1H-^1H$ correlation spectroscopy, heteronuclear single quantum correlation, and heteronuclear multiple bond connectivity, to determine exact peak assignments.

A repeated silica Rel column chromatography of n-BuOH fraction from the larva of Allomirina dichotoma afforded a purified nucleic acid, which was identified as inosine on the basis of the spectroscopic data including IR, MS and NMR. The HPLC analysis of the index component using silica based $NH_2$-column exhibited the contents in the hot air-dried and Far-IR-dried larvae of Allomirina dichotoma as 0.003% and 0.055%, respectively.

Objectives: This study aimed to investigate the clinical characteristics of patients with gastroesophageal reflux disease (GERD) according to globus sensation (GS). Methods: We reviewed the clinical records of 29 GERD patients who visited the Department of Digestive Diseases of Kyung Hee University Korean Medicine Hospital from March 1, 2018 to February 28, 2019. The subjects were classified according to the presence of globus sensation, and the two groups were compared in terms of heart rate variability (HRV) and the Ryodoraku results. Results: In comparing the GERD with GS group (GS group) and the GERD without GS group (non-GS group), a significant difference was found in the duration of symptom and several HRV parameters. The duration of the symptom in the GS group was significantly longer than that in the non-GS group. The non-GS group showed a significantly higher value of total power and high frequency than the GS group. Conclusions: The results suggest a significant difference in the stress level between patients with GERD with GS and those without GS. When approaching patients with GERD without GS, their stress status should be considered.

목적 : 한의학 분야에서 육계(CCE: Cinnamomum cassia)는 혈류 순환이 저하된 상태에 널리 쓰이는 약재이다. 이 연구에서는 CCE와 그 활성 혼합물인 cinnamic acid가 in vitro와 in vivo에서 발휘하는 신생혈관 형성 작용에 대해 알아보고자 한다. 방법 : CCE와 CA의 신생혈관형성 작용을 알아보기 위하여 Human unbilical endothelial cells(HUVECs)와 Bovine arterial endothelial cells(BAECs) 그리고 Matrigel assay를 이용하였다. 결과 : In vitro에서 CCE와 그 활성 혼합물은 HUVEC 증식, 이동, 모세혈관-유사 관 형성을 유도한다. CCE에서의 25-50% 증가(1 또는 10ng/ml 용량에서)는 CA에서 증식과 유사하게 나타났다. HUVEC에서는 증식이 뚜렷하게 나타났으나 BAEC에서는 증식이 뚜렷하게 나타나지 않아 증식 효과는 내피세포의 기원에 따라 다른 것으로 나타났다. BAEC는 CCE와 CA에서 증식은 보이지 않았지만 이동과 모세혈관-유사 관 형성 또는 분화를 보였다. 또한 CCE와 CA는 HUVEC에서 VEGF 발현과 Flk-1/KDR 발현을 각각 2.2배와 2.5배 증가시켰다. 결론 : CCE와 그 활성 혼합물은 in vivo와 in vitro에서 혈관 내피세포의 VEGF 발현을 통하여 신생혈관 형성 작용을 유도하며 이는 앞으로 다른 한약 추출물의 신생혈관형성 촉진 작용 연구에 모델을 제시할 것으로 보인다.

We present collections of optical photometry for a pre-main sequence star HBC 722. It showed large amplitude optical outburst (${\Delta}V=4.7$ mag) in 2010 and classified as a FU Orionis type object. We have been observing HBC 722 from 2011 April to 2013 May, using Camera for QUasars in EArly uNiverse (CQUEAN) attached to the 2.1 m Otto Struve telescope at the McDonald Observatory. Time-series monitoring data (minute-scale interval) were obtained in SDSS r, i and z bands to see short-scale behaviors as well as trace the long-term brightness changes after the eruption in 2010. Interestingly, it started to brighten from 2011 early summer and became brighter than the first outburst peak in our 2013 May observation. We expect that the recovering phase would result from re-increase of disk accretion rate, might attribute to distinctive short-scale color features. In this presentation, we report long- and short-timescale optical behaviors of HBC 722 in the post-outburst phase.
