Atopic dermatitis is a chronic inflammatory skin disease associated with cutaneous hyper-reactivity to environmental triggers. In order to develop effective therapeutic herbal extracts for atopic dermatitis, cytotoxicity, antioxidant, anti-inflammatory and anti-allergic activities were investigated for various herbal extracts. Among candidate extracts, we selected Aloe vera L. (AV), Viola mandshurica W. Becker (VM), Punica granatum L. (PG), Dendrobium nobile L. (DN) and mixture of the above extracts (MX) for further investigations. All of them did not show cytotoxic activities to macrophage RAW264.7 cells below the concentration of 100 ppm. All showed antioxidant, anti-inflammatory and anti-allergic effects, although to various extents. In antioxidant effects, AV showed the highest effect, followed by PG and VM, while DN did the lowest. In evaluation for anti-inflammatory activities in macrophage RAW264.7 cells, AV and DN inhibited almost completely the LPS-induced production of nitric oxide, while AV, DN and VM showed strong inhibitory activities on the LPS-induced production of TNF-${\alpha}$. In anti-allergy effect in mast cell HMC-1, DN showed the highest effect, followed by AV and PG, while VM did the lowest. In the topical allergy reaction induced by compound 48/80 in Sprague-Dawley rat, DN exhibited significant anti-allergic effect, while PG, VM and AV did slight effect. These results suggest that AV, VM, PG and DN have antioxidant, anti-inflammatory and anti-allergic activities, and thus have the potential to reduce and alleviate the symptoms of atopic dermatitis.

Objective : The purpose of this clinical research was to analyze the correlation between disease severity and disease specific quality of life adjusted by general quality of life measure in adult patients with atopic dermatitis attending Wonkwang Univ. Sanbon Oriental Medical Center. Methods : A total of 35 patients participated in atopic dermatitis clinical trial from June 1st, 2010 to June 30th, 2011 were included in this study. SCORing Atopic Dermatitis(SCORAD) index, Dermatologic Life Quality Index(DLQI), Health Utility Index III(HUI-III) and EuroQoL 5-Dimension(EQ-5D) have been estimatied. Baseline statistical analysis and normality test were done by using Student t-test, Shapiro-Wilk test and ladder test. Pearson analysis and Spearman analysis were conducted to examined the correlation of each variables. Hierachial regression analysis was performed using related variables. Statistical significance was achieved if the probability was less than 5%. Results : There were statistically significance between DLQI and SCORAD index, and also between DLQI and EQ-5D. However there was no significant between DLQI and HUI-III. In the hierachial regression analysis, after adjusting for demographic variables (gender, age) and general quality of life (EQ-5D), SCORAD index significantly predict the intensity of disease specific quality of life (DLQI). Conclusions : We confirmed the correlation between SCORAD index and DLQI, and developed the inference for regression equation of DLQI using SCORAD index, EQ-5D and demographic variables.

Objectives: The purpose of this study was to investigate the effects of Angelica gigas Nakai extract(AGNE) and Bacillus polyfermenticus KJS-2 (BP2) on atopic dermatitis (AD) induced by 2, 4-dinitrochlorobenzene (DNCB) in mice. Methods: In the experiment, we divided mice into four groups: a control group, a DNCB group, an AGNE group, and an AGNE+BP2 group. Then we examined the changes in scratching frequency, clinical aspects on dorsum skin, immunoglobulin (IgE), cytokines ($TNF-{\alpha}$, IL-6) and expression of COX-2. Resutls: From the experiment, the scratching frequency was significantly dropped in AGNE group and AGNE+BP2 group. Clinical observations of dorsum skin, there were a severe keratotic lesion and drop of dead skin cell in DNCB group, but symptoms of AD were decreased 39.6% in AGNE group and 49.6% in AGNE+BP2 group during 3 weeks. IgE, $TNF-{\alpha}$ and IL-6 were decreased significantly in both AGNE and AGNE+BP2 group. Expression of COX-2 was also decreased significantly in both groups. Conclusions: In conclusion, these data suggest that AGNE can decrease symptoms of AD and BP2 makes AGNE more effective. So AGNE can be useful herbal therapy for AD.

Objective : The aim of this study is to assess the impact of chronic atopic dermatitis (AD) on quality of life (QoL) as well as the economic burden associated with oriental medical treatment on adult patients with chronic AD in Korea. Methods : The EQ-5D health states, existence and duration of AD in the 2007 National Health and Nutrition Examination Survey (NHANES) were used to obtain the study subjects. A questionnaire including the questions on direct medical and direct non-medical costs associated with oriental medical treatment for adult patients with AD was specifically designed. Twenty-nine, members of the Korean Oriental Medical Ophthalmology, Otolaryngology and Dermatology Society (KOMOODS), completed the questionnaires. Results : The incidence of AD was around 3.09% in 2007 NHANES (sample survey, n=2981). Three months and above in duration of disease was 1.35%. The QoL data revealed as follows: 0.932 in non-chronic AD, 0.916 in chronic AD, and 0.908 in non-AD. We also stratified our analysis by age. The QoL data in 40's was statistically significant (P<0.023). But, no significant differences were reported in 20's, 30's, and 50's. The total direct medical costs of oriental medical treatment for AD was about 2,560,717 Won, and total direct non-medical costs was about 605,125 Won in a year. Conclusions : This study might be applied to find the evidence of economic evaluation in oriental medicine for AD. More rigorous studies are warranted.

Objectives : This study aims to evaluate the effects of natural herb mixutre (NHM) on atopic dermatitis and skin regeneration using in vivo test. Methods : NHM was prepared with DW. 25% of NHM was applied to skin lesion, where atopic dermatitis was induced by DNCB in NC/Nga mice. The levels of cytokines (IL-4, IL-5, IL-6, IL-13, TNF-a, and $IFN-{\gamma}$), and IgE in serum were measured by Luminex. Immune cells (WBC, eosinophil, lymphocyte, and monocyte) in blood were counted by coulter counter. The gross investigation of atopic dermatitis index score test were performed during the NHM treatment period. Also, the histopathological change of dorsal skin was observed by H&E and M&T staining. Results : NHM showed the levels of IL-4, IL-5, IL-6, IL-13, IgE, WBC, eosinophil, lymphocyte, and monocyte in serum or blood were significantly decreased. On the contrary, the productions of FGF, and VEGF were increased in the serum. Also, atopic dermatitis index score in NHM-treated mice were observed in the similar levels to those of normal group. Histological examination demonstrated that NHM suppressed immune cell infiltration and thickening of epidermis, meanwhile the extraction induced collagen production in the dorsal skin. Conclusion : This study demonstrated that NHM is appeared to be effective on atopic dermatitis and skin regeneration efficacy based on the observations with hematologic, gross, and histologic examinations. Therefore, we suggest that NHM could be effectively used as an external therapeutics against atopic dermatitis and a consequence skin damage.
