  • Atopic disease is caused by a complex combination of environmental factors and genetic factors, and studies on influence of exposure to various environmental factors on atopic diseases are continuously reported. However, the exact cause of atopic dermatitis is not yet known. Our study was conducted to analyse the association of SNPs with the development of atopic disease in a small cohort. Samples were collected from the Mothers' and Children's Environmental Health (MOCEH) study and 192 cord blood DNA samples were used to identify incidence of atopy due to influence of exposure to environmental factors. Genetic elements were analysed using a precision medicine research (PMR) array designed with various SNPs for personalized medicine. Case-control analysis of atopy disease revealed 253 significant variants (p<0.0001) and SNPs on five genes (CARD11, ZNF365, KIF3A, DMRTA1, and SFMBT1) were variants identified in previous atopic studies. These results are important to confirm the genetic mutation that may lead to the onset of foetal atopy due to maternal exposure to harmful environmental factors. Our results also suggest that a small-scale genome-wide association analysis is beneficial to confirm specific variants as direct factors in the development of atopy.

  • This study aims to evaluate the anti-inflammatory effect of Coptidis Rhizoma (CR) extract for atopic dermatitis through maintaining skin barrier and regulating Th2 cell differentiation. We divided NC/Nga mice into 3 groups as follows; atopy-like dermatitis induced group with CR treatment (CT, n=10), no treatment group(Ctrl), atopy-like dermatitis elicited group(AE). Atopy-like dermatitis was induced to NC/Nga mice by sensitizing with dermatophagoides farinae(DfE) on 7, 8, 9, 11, 12, and 13th week. After inducing atopic dermatitis, CR extract was administered 20 mg/kg daily for the experimental duration to the CT group. We measured the integrity of lipid layers in the epidermis and Th2 differentiation through immunohistochemical staining against filaggrin, loricrin, IL-4, and IL-13. We also measured the distribution of subcutaneous collagen fibers by the Masson's trichrome staining. Administration of CR significantly inhibited the reduction of lipid layers in the skin that caused atopy. The expression of IL-4, IL-13, each of which is a cytokine secreted by T helper type 2 (Th2) cells, was markedly suppressed in the CT group as compared with AE group (p<0.05). CR treatment also decreased the expression of iNOS, $p-I{\kappa}B$. Atopic dermatitis induced dermatological damage to skin, such as hyperplasia of epithelium, and capillary proliferation was significantly reduced by CR administration. CR effectively inhibited the thinning of the skin barrier and inflammatory responses in atopic dermatitis-induced mice. In particular, it showed anti-inflammatory effects by reducing the expression of IL-4 and IL-13, Th2 cell cytokines, which play a crucial role in development of atopic dermatitis. Therefore, CR can be a good candidate to ameliorate and treat atopic dermatitis.

  • Purpose: The purpose of this study was to investigate the factors associated with atopic dermatitis in Korean adults. Methods: The data were obtained from the Korean National Health and Nutrition Survey on 2008. Subjects of this study were 7,280 adults aged older than 18 years. The data were analyzed for demographic characteristics, health status, alcohol drinking, smoking, hypertension, hyperlipidemia, asthma, chronic sinusitis, rhinitis, stress, depression, and suicidal ideation between atopy group and non-atopy group. Results: Among 7,280 subjects, 2.9% of Korean adults had a diagnosis of atopic dermatitis from doctor. Multiple logistic regression identified that the presence of atopic dermatitis was associated with marital status (OR=2.66, CI 1.84~3.86, p<.001), rhinitis (OR=1.52, CI 1.04~2.22, p = .030), and depression (OR=1.89, CI 1.04~3.41, p = .036). Conclusion: Based on these results, marital status, rhinitis, and depression should be considered in addressing individuals with atopic dermatitis. And the other factors contributing to atopic dermatitis need to be specifically identified.

  • Introduction : Atopic dermatitis is very epidermic disease in these days. Atopic dermatitis is difficult for patient to be treated because there is no specific treatment. The oriental method of atopic dermatitis is varied as patient situation and doctor's view point. The Treatise on Febrile Diseases(傷寒論) may be a hint for atopy disease. Object: Although we use various method such as acupucture, aroma therapy, a medicine for external use, we use the two decoctions in the Treatise on Febrile Diseases according to differentiation of syndromes and abdominal diagnosis. Result : After inpatient treatment in 21 days, the itching, redness, exudation, crust, lichen get better and insomnia and constipation was removed quickly. The SCORAD index is decreased from 84.2 to 25.9. Conclusion : These decoction can treat the atopic dermatitis although there is no symptom in atopy because we cure the all situation of the patient. We can cure the atopic dermatitis not only by routine remedy for various symptoms but also by diagnosis and treatment based on overall analysis of symptoms and signs.

  • Objectives : The purpose of this study is to evaluate clinical utilization by measuring compliance with the use of mobile health applications (AtopyPHR developed in a previous study) for patients with atopic dermatitis. Methods : Based on the AtopyPHR and the input period and frequency survey results for each symptom item, a scenario for measuring compliance was derived. The study period was 4 weeks. Participants installed AtopyPHR app and Telegram app on their smartphones, conducted user training on the app, and recorded symptoms using the app for 4 weeks. At the 2nd and 4th week visits, the AtopyPHR data recorded by the user can be viewed on the web page and used for medical decision. Compliance was analyzed by the date the symptoms were recorded. Results : There were 28 participants, all (100%) were compliant, and the compliance was 96.8. The patients were 1 to 18 years old, and the average age was 8.2±5.7 years, 10 males and 18 females. The actual date of participation in recording symptoms was 28.6±0.56 on average. Compared to Week 1, compliance decreased at Week 2, and Week 4 had the highest compliance. Daily check, daily emotion, stool/urine/sleep, and meal management showed high compliance, SCORAD and quality of life were higher than required to record. Conclusions : AtopyPHR was effective in compliance. The results of this study could be used to collect personal health data in daily life through the AtopyPHR, improving participant compliance. It is considered to be meaningful because it measured the compliance with the symptom record actually recorded using the mobile app rather than a questionnaire. This study may be useful not only for personal health care but also for medical decisions, as opinions are given by experts who treat atopic dermatitis.

  • Objective : The aim of this study was to search and analyze the herbal combinations in formulas used to treat atopic dermatitis in Korean medicine. Methods : Articles on the atopy were searched for from among those registered on the OASIS up to December, 2015. After the articles were reviewed, information on both internal and external formulas for atopy was constructed. Then, the herbal combination in the formulas was analyzed by using frequency distribution, network analysis, and data mining. Results : The combination of 'Saposhnikovia Radix - Schizonepetae Spica' and 'Scutellariae Radix - Phellodendri Cortex ' was mostly used in both internal and external formulas to treat atopy in articles. By using the network analysis and data mining, twelve combinations including ' (Saposhnikovia Radix, Ponciri Fructus Pericarpium) - (Platycodi Radix, Schizonepetae Spica) ' were discovered. Five effective combinations were also searched for external formulas.Conclusions : This study could help researchers to analyze the formulas in various ways. Moreover, the herbal combination in atopy formulas could be used to search for atopy formulas in other databases or make a new prescription.

  • Objectives: Natural environment therapy is considered as an option for atopic dermatitis. This study was aimed to examine the beneficial effects of natural environment therapy among patients with atopic dermatitis who have moved in an atopy-free village. Methods: The questionnaire-based survey was conducted from parents of 20 children with atopic dermatitis (12 male and 8 female, median age 8 years, ranging from 6 to 13 years). The questionnaire consisted of 10 questions for the changes of two typical symptoms of pruritus and sleeping difficulty after moving into an atopy-free village. Results: 75.0% and 88.9% of patients have a family history (at least one parent and one of siblings respectively) of allergic disorders. The median staying period of patients was 27.6 months (ranging from 2 to 55 months). The score indicating pruritus was significantly improved from $6.2{\pm}2.8$ into $4.8{\pm}1.8$ (p<0.05), and sleeping difficulty was also improved from $5.7{\pm}2.9$ into $4.3{\pm}2.1$ (p<0.05) too. Conclusions: This study suggests that the natural environmental therapies could be a choice for patients with atopic dermatitis, which should be studied further for their scientific evidence and mechanisms.

  • Purpose : To investigate the effects of the lavender, lemon and eucalyptus oil mixture on the atopy dermatitis skin lesions induced on NC/Nga Mice by dinitrochlorobenzene (DNCB). Material and Method : For this purpose, we fabricated the oil mixture blending three essential oils (lavender, lemon, eucalyptus : ELL) with one carrier oil (jojoba) and apply it on the atopic dermatitis skin lesions of NC/Nga Mice. Atopic dermatitis in NC/Nga Mice was induced by DNCB treatment on the dorsal skin of mice for 8 weeks. The mixture of ratio of each essential oil drop was 1 (eucalyptus) : 2 (lemon) : 2 (lavender) and this mixture was blended with jojoba oil 50ml (0.025%). The ELL-ointment was supplied for 8 weeks. We evaluated the effects of ELL on cell viability of mouse lung fibroblast, clinical skin features and severity, the level of serum Immunoglobulin (Ig) E & Ig G1, Interleukin (IL)-4, IL-13 and Interferon (IFN)-$\gamma$. Results : ELL showed safety on the cell viability of mouse lung fibroblast compared with control group. The cell viability was measured by SRB method. The effects of ELL on clinical skin features and severity in DNCB-induced dermatitis model of NC/Nga mice was significant compared with control group. EEL also showed significant effects on clinical symptom score compared with control group. Serum IgE & IgG1 level and development of atopy dermatitis skin lesions were evaluated. Serum IgE & IgG1 production was significantly down-regulated in EEL group compared with control group. ELL also down-regulated the levels of IL-4 and IL-13, and up-regulated the level of IFN-$\gamma$ compared with control group significantly. Conclusion : ELL was effective on atopy dermatitis by modulating Th2 related factors.

  • We investigated the inhibitory effect of an oral administration of a Sophora flavescens Aiton ethanol extract (SFE) on the development of atopic dermatitis (AD) by using NC/Nga model mice. The induction of atopic dermatitis-like lesion was conducted by the removal of the back hairs and topical application of a mite antigen (Dermatophagoides farinae, Df) on to the back skin twice a week for 8 weeks. SFE was orally administered at a different doses (100-400 mg/kg). Atopic dermatitis-like skin lesions were evaluated by dermatitis scores, skin histology and immunological parameters (serum levels of IgE, TARC/CCL17, MDC/CCL22, and CTACK/CCL27). Oral administration of SFE significantly inhibited the clinical sign of Df-induced atopic dermatitis, including dermatitis score and leukocyte infiltration. Moreover, SFE suppressed significantly the serum IgE and Th2 chemokine (TARC/CCL17, MDC/CCL22, and CTACK/CCL27) levels in a concentration dependent manner. These results suggest that oral administration of SFE could reduce significantly the clinical signs and Th2 chemokines in Df-induced atopic dermatitis model mice. Therefore, SFE may be effective substances for the management of AD in human.

  • This study was conducted with 60 adult males who visited the Atomi Cooperative Clinic(Atomi Dermatology/Pediatrics/Oriental Clinic) in Seoul between May 2003 and December 2004; they were divided into three groups, each of which consisted of 20 persons, according to the level of erythma and then each group was subdivided to consist of ten according to whether they received skin treatment and care. The standard care provided to two groups involved topical steroids and oriental medicines prescribed by a dermatologist and a oriental doctor, respectively. 5th-grade topical steroid ointment was applied to the face and 3rd-grade to the limbs; a oriental medicine was administered in a lukewarm state half an hour after meals three times a day. To determine how special and systematic skin treatment and care was helpful in treating atopy, a skin treatment system was applied to the experimental group while the control group was provided with standard care alone. By using Mexameter(MX18) manufactured by ck-mpa as a measuring tool, the inflammation level was observed at the right antecubital space during each visit to the clinic. In view of the re suits, introduction of the systemic skin care for A. D to legitimate treatment provided by a medical institution is expected to be an appropriate supplementary treatment for adult patients who suffer from frequent recurrence of atopic dermatitis.
