  • Background: Panax ginseng Meyer is one of the most valuable medicinal plants which is enriched in anti-microbe secondary metabolites and widely used in traditional medicine. Botrytis cinerea is a necrotrophic fungus that causes gray mold disease in a broad range of hosts. B. cinerea could overcome the ginseng defense and cause serious leaf and root diseases with unknown mechanism. Methods: We conducted simultaneous transcriptomic and metabolomic analysis of the host to investigate the defense response of ginseng affected by B. cinerea. The gene deletion and replacement were then performed to study the pathogenic gene in B. cinerea during ginseng - fungi interaction. Results: Upon B. cinerea infection, ginseng defense responses were switched from the activation to repression, thus the expression of many defense genes decreased and the biosynthesis of antifungal metabolites were reduced. Particularly, ginseng metabolites like kaempferol, quercetin and luteolin which could inhibit fungi growth were decreased after B. cinerea infection. B. cinerea quercetin dioxygenase (Qdo) involved in catalyzing flavonoids degradation and ∆BcQdo mutants showed increased substrates accumulation and reduced disease development. Conclusion: This work indicates the flavonoids play a role in ginseng defense and BcQdo involves in B. cinerea virulence towards the P. ginseng. B. cinerea promotes disease development in ginseng by suppressing of defense related genes expression and reduction of antifungal metabolites biosynthesis.

  • Objectives : The aim of this experiment is to find out relationship between the effect of cosmetics and 4 types of pattern identification about fluid-humor, which are based on the general idea of traditional oriental medicine, Qi-Blood and deficiency-excess. Methods : Korean female volunteers in good health (n=25, $23.12{\pm}2.83$) participated in this experiment. Three Korean medical doctors classified them into 4 groups: Blood-deficiency: group A; Blood-excess: group B; Qi-deficiency:group C; Qi-excess:group D). Cosmetics that contains herb extract for Blood deficiency were given to all volunteers and they used the cosmetics for 4 weeks. Volunteers were assessed non-invasively with the skin measuring devices before and after using cosmetics. And we analyzed the correlation of skin physiological parameters with 4 groups. Results : Three doctors diagnosed participants and classified them into 4 groups ; group A(n=8),group B(n=7), group C(n=3), group D(n=5) as highest score. After 4 weeks, facial skin moisture showed no significant difference in comparison between 4 groups. Sebum showed significant increase in Group A and significantly decreased Group B. Measurement of facial skin elasticity tended to increase in Group A, C, D but skin elasticity was decreased significantly in Group B. Conclusions : In case of a group that pattern identification about fluid-humor corresponds to herb extract in cosmetic, skin improving effect was better than the other group that pattern identification oppose to properties of herb in cosmetic. Therefore, from the view of traditional oriental medicine, it is very important to understand user's pattern of identification or physical conditions and properties of herbs in cosmetics on the matter of safety and efficacy.

  • Acupuncture and herbal treatment are based on diagnosis of cold and heat pattern in Traditional Korean Medicine. This diagnosis is accomplished through pulse, tongue and question examination, which are not objective. Quantification and objectification of this diagnosis process are required for efficacious treatment and traditional medicine development. In this study, we developed the cold-heat pattern questionnaire for this purpose. Seventy nine patients who visited oriental medical hospital were included in this study. The cold-heat pattern questionnaire was composed of many questions about patient's physical condition, which were derived from The Traditional Oriental Medical Literature with Delphi Technique. Patients filled out the cold-heat pattern questionnaire by themselves. Diagnosis of cold and heat pattern are conducted separately by oriental medical doctors with more than 5 years' clinical experience. Various physical condition factors were derived for the cold-heat pattern questionnaire. (Preference temperature, Body temperature, Pain type, Face color, Urine, Stool and secretion features) Each cold and heat symptoms group acquired internal consistency. (Cronbach's ${\alpha}$ : Cold - 0.605, Heat - 0.722) There were significant associations between doctor's diagnosis and cold symptoms in 'Aversion to cold', 'Desire for heat', 'Pale face', 'Loose stools'. (p-value < 0.05) There were significant associations between doctor's diagnosis and heat symptoms in 'Desire for cold', 'Body feverishness', 'Thirst'. (p-value < 0.05) The internal consistency results suggest that the cold-heat pattern questionnaire assured reliability. Besides, these results showed that cold-heat symptoms are apt to appear together with, and this can be indirect evidence that diagnosis of cold-heat pattern is valuable for comprehension about disease pattern. Moreover, respective symptoms of cold-heat pattern showed different significance with doctor's diagnosis. Consequently these significant symptoms can be more considered for comprehension of cold-heat pattern.

  • Angelica sinensis radix, Danggui, is a traditional oriental medication, which has been used to modulate immune response. We report here that aqueous extract of Angelica sinensis radix (ASR) can induces NO production, and inhibit LPS-induced NO production in dose-dependent manner in RAW 264.7 macrophage cells. ASR also induces iNOS mRNA and iNOS protein expression, and exhibit inhibitory effect on iNOS mRNA and protein expression in a dose-dependent manner in LPS-stimulated RAW 264.7 macrophage cells. Cytokines involved in the regulation of inflammatory reaction and immune response may play a role in the pathogenesis. ASR induces. pro-inflammatory cytokine gene expression (IL-1α, IL-1β and IL-6 gene) in a dose-dependent manner, and inhibits the expressions of these cytokines in LPS-stimulated RAW 264.7 macrophage cells. These data indicate that (1) ASR may be a potential therapeutic modulator of NO synthesis in various pathological conditions, and (2) the immunomodulatory effects of ASR may be, in part, associated with the inducing or suppression of pro-inflammatory cytokine gene expressions.

  • The objective of this study was to investigate the diagnosis and treatment of Sjogren's syndrome(SS) such as syndrome differentiation and herbal medicine by reviewing Chinese traditional medicine's journals. The journal search was carried out using China National Knowledge Infrastructure(CNKI) and PubMed from January 2007 to July 2012. Searching key words were the various combination of "Sjogren's syndrome", "Traditional Chinese Medicine", "herbal medicine", and "syndrome differentiation". The final selection of 57 studies were extracted and summarized by two researchers independently. The syndrome differentiation was classified as yin deficiency with fluid depletion, yin deficiency with dryness heat, dryness toxin with yin damage, internal obstruction of static blood, dual deficiency of qi and yang, dampness-heat obstructing, wind with external contraction, liver qi depression, blood deficiency and wind-dryness, dual deficiency of yin and yang, and internal obstruction of phlegm-blood stasis. Liriope platyphylla(麥門冬), Rehmania glutinosa(生地黃), and Scrophularia buergeriana(玄蔘) were primarily prescribed to tonify yin, engender fluid and moisten dryness.

  • About 60% to 90% of a total population experience low back pain at least once of life, and about 35% to 79% among them experience a recurrent and chronic low back pain. thread-embedding therapy is mainly used to improve appearance or treat obesity in early stage, but recently it is also used to treat musculoskeletal pain. This study aimed to search Chinese study using thread-embedding therapy on low back pain and to analyse their methodology. Three Chinese database(CNKI(www.cnki.net), WANFANG(www.wanfangdata.com), WEIPU(www.cqvip.com)) were searched for clinical study of thread-embedding therapy up to March 2016. The characteristics of included studies and regimen of thread-embedding in those studies were analyzed. The total 21 studies (4 case studies, 16 non-randomized controlled trials, 1 randomized controlled trial) were included. All studies on thread embedding treatment of low back pain reported that its effectiveness was very good. The most frequently used acupoints was Ashi acupoints and acupoints on bladder meridian(BL) or governor vessel(GV). Thread-embedding therapy is considered very useful for low back pain in Traditional Chinese medicine. Further studies are needed to investigate the effect of thread-embedding therapy and to expand its application. This study is limited in that the literature search in the Chinese database were restricted.

  • In East-South Asia it has been known that Korean ginseng(Panax ginseng) increases blood pressure, whereas American ginseng(Panax quinquefolius) doesn't. This study was designed to find out if Korean ginseng really could increase blood pressure comparing with American ginseng. Double-blind randomized controlled trials on blood pressure and pulse rate of Korean ginseng and American ginseng in Koreans and Chineses was performed. There was no significant difference on blood pressure and pulse rate between Korean ginseng and American ginseng in both Koreans and Chineses by repeated-measures ANOVA. It was revealed that Korean ginseng does not increase blood pressure. Maybe the concept that Korean ginseng increases blood pressure is concerned with commercial interests dealing with American Ginseng.

  • The aim of this study was to investigate the difference of electrodermal activity between the hypertensive and non-hypertensive subjects. A total 161 subjects who visited a hospital for health check ups from August 2011 through November 2011 and from September 2012 through November 2012 were included in this study. We divided the subjects into two groups by blood pressure, hypertension group(81 patients) and non-hypertension group(180 subject). Then we compared electrodermal activity between two groups by using the autonomic bioelectric response device model CP-6000A. The data was analyzed by independent t-test and logistic regression. In this study, there was a significant difference in electrodermal activity(the mean absolute value of positive, negative pulse conductivity) between hypertensive and normotensive group in t-test and electrodermal activity showed the significant influence on the prevalence risk of hypertension with age, body mass index and dyslipidema in binominal logistic regression. In conclusion, hypertensive patients had high level of electrodermal activity compared with normotensive subjects and this finding suggests that electrodermal activity which is explained excess tendency in Korean traditional medicine could be used for diagnosis in hypertension patients at Korean traditional medical clinic.

  • Bioelectrical Impedance Analysis (BIA) is a non-invasive and low-cost technique that estimates body composition based on the distribution of water and electrolytes in the body by analyzing body's electrical responses to source voltages. In this work, we carried out a systematic literature review on BIA researches in traditional East Asian medicine (TEAM). For comparison, firstly we introduced the concept and principle of BIA, and offered a general overview of research trends in western medical perspectives. We searched through the databases of Oriental Medicine Advanced Searching Integrated System and DataBase Periodical Information Academic for the articles published between 1994 and 2013, with keywords such as 'BIA', 'bioelectrical impedance' and 'impedance'. Among the rough-searched 274 articles, we finally selected 21 articles appropriate to the intended research field. The selected articles were categorized into diagnosis in Sasang medicine, impedance analysis in meridian system, and change of body composition after taking herbal medicine. We found that most of BIA researches in TEAM were preliminary and remained in the peripheral levels which is far behind the western medical research activities. Therefore, more efforts are needed to study BIA in association with major subjects such as pattern identification or physiological/pathological phenomena. In addition, methodological breakthrough of BIA is possible by applying the diagnostic concepts of the TEAM in relation to the balance of Qi and Blood.
