In order to investigate the efficacy of BJBB on atopic dermatitis, various immune related factors were studied. The results and conclusions are as follows. Atopic dermatitis symptoms were improved in BJBB treated group and significant decrease in dermatitis index were observed in 13 weeks. ALT, AST and BUN, Cr levels were all with in the normal ranges in BJBB treated group, indicating no induced toxicity. BJBB treated group showed significant decrease in CD4+, CD11b+/Gr-1+ immune cell ratio in dorsal skin by 33% and 62% respectively. BJBB treated group showed significant decrease in the expression of IL-4, IL-5, IL-13 and histamine by 83%, 62%, 53% and 61% respectively. Also the group showed decrease in the transcription of IL-4, IL-5 and IL-13 mRNA in spleen by 41%, 52% and 50% respectively. BJBB treated group showed decrease in the expression of IgE by 57% respectively. The results above indicated that treatment of BJBB improved atopic dermatitis symptoms by immune modulation activity a clinical evidence. thus, BJBB has a potential use as a composition of medicinal plants for treatment against inflammation related disease.

Objectives : Atopic dermatitis is a chronic inflammatory skin disease which is characterized by severe pruritis, erythema, edema, effusion and scabs. The aim of this study was to understand effects of Arctium lappa Linne, which is well known for its efficacy for various skin diseases, on atopic dermatitis Methods : We conducted this experiment using the DNFB-induced NC/Nga mice. After two weeks of applying DNFB to NC/Nga mice, severe symptoms of atopic dermatitis occurred. We divided the mice into three different groups: a control group which was given no treatment at all, a group treated with dexamethasone (1mg/kg), and another group treated with Arctium lappa Linne (300mg/kg). After one week of treatment, results were recorded according to their improvement on skin, itching behavior, IL-4, and INF-$\gamma$ measurement, which is a significant criterion for diagnosing atopic dermatitis. Results : Itching behavior showed significant improvement in the Arctium lappa Linne group. However Arctium lappa Linne failed to reduce IL-4 and INF-$\gamma$ count. Also there was no satisfying improvement on AD-like skin lesions on the rostral back of the NC/Nga mice treated with Arctium lappa Linne. Conclusions : Arctium lappa Linne showed improvement in itching behavior in NC/Nga mice induced by DNFB. Arctium lappa Linne showed neither significant improvement on skin lesions nor in IL-4 and INF-$\gamma$ measurement.

The prevalence of Atopic Dermatitis (AD), a non-infective chronic inflammatory skin disease, is increasing worldwide. Avoiding the allergen is the basic principle in the treatment of AD. However, when the allergen is food, excessive restriction can lead to nutrition deficiency. The objective of the study was to examine the status of the dietary restriction and compare the caregiver's restriction practice with doctor's recommendation in Korean children with AD. A total of 158 children diagnosed with Atopic Dermatitis were recruited for this study. Information about foods that aggravate AD symptoms and food restriction were collected from the mothers of 158 children aged 6 month-5 year with AD using questionnaires. Food restriction recommendation by doctor was collected through medical chart. McNemar and Margianl homogeneity tests were used to detect a relationship between food restriction recommended by doctor and current practice by mother. There were significant proportion differences of food restriction for each food between by doctor and mother. We found 75.9% of children were avoiding eggs although only 61.4% were recommended for egg restriction by a doctor. Children with restriction of more than 4 kinds of food were 53.2% compared to 13.3% by doctor. Excessive restrictors tended to be younger and diagnosed at younger age. The caregivers of excessive restrictors had trends of "being older" and "having higher income". Avoidance of common foods in children without food allergy could result in malnutrition or impaired growth. Nutrition education is needed for sound practice and nutrition care in children with Atopic Dermatitis as well as interactive communication between caregivers and experts.

Atopic dermatitis (AD) is a chronic inflammatory skin disease accompanied by severe itching, mainly before five. The aim of this study is to investigate the effects of 405 nm+850 nm LED light therapy on AD-like symptoms in NC/Nga mice. The mice were randomly placed in the normal (Vehicle), atopic dermatitis-induced (CON), and 405 nm + 850 nm LED light therapy (LED) groups. The LED experimental group conducted 405 nm+850 nm wavelength LED ray therapy for 10 minutes a day for seven days. LED light therapy research confirmed the improvement and improvement of Dermatics score and observed the reduction of epidermal tissue thickness caused by dermatitis. Based on the significant decrease of serum IL-1𝛽 and transdermal moisture loss and serum IgE concentration due to LED light therapy, LED light therapy can help restore normal skin conditions in mice that cause atopic dermatitis. This study showed the anti-atopic effect of infrared light and blue light. Light in mice with atopic dermatitis led to the simultaneous use of circular LEDs with two wavelengths.

Objectives: To investigate trends in the prevalence of allergic disease over a 9-year period. Methods: Using National Health Insurance Service (NHIS) data, the annual number of patients with allergic disease was obtained for each regional subdivisions (small cities, counties, and districts) from 2003 to 2011. Annual populations for each sub-region were obtained and used to calculate the standardized prevalence. To compare prevalence within the study period, data was standardized spatially and temporally. For standardization, demographic data was used to obtain the registered population and demographic structure for 2010, which was used to perform direct standardization of previous years. In addition, a geographic information system (GIS) was used to visualize prevalence for individual sub-regions, and allergic diseases were categorized into five groups according to prevalence. Results: The nationwide outpatient prevalence of allergic rhinitis increased approximately 2.3-fold, from 1.27% in 2003 to 2.97% in 2013, while inpatient prevalence also increased approximately 2.4-fold,. The outpatient prevalence of asthma increased 1.2-fold, and inpatient prevalence increased 1.3-fold. The outpatient prevalence of atopic dermatitis decreased approximately 12%, and inpatient prevalence decreased 5%. Conclusions: There was a large difference between prevalence estimated from actual treatment data and prevalence based on patients' self-reported data, particularly for allergic rhinitis. Prevalence must continually be calculated and trends should be analyzed for the efficient management of allergic diseases. To this end, prevalence studies using NHIS claims data may be useful.

The prevalence of atopic dermatitis (AD), chronic cutaneous disease, has increased rapidly worldwide. Since AD is the most common disease affecting infants, maternal food intake during pregnancy as well as lactation is important. The purpose of this research was to examine the difference in maternal food intake during pregnancy between mothers having children with or without AD. One hundred forty-eight mothers with children aged under 2 years with AD (AD group, n=74) or without AD (non-AD group, n=74) were included in the study. Diet during pregnancy was examined using a food frequency questionnaire. There were no differences in the status of mothers' food consumption during pregnancy between the AD and non-AD groups. Mothers in the AD group consumed significantly less white fish (P<0.05), carrot & pumpkin (P<0.01), walnut & pine nut (P<0.05), mandarin & orange (P<0.05), and peach (P<0.05) than those in the non-AD group. As food frequencies were categorized according to <1/month, 1~3/month, 1~6/week, and 1~3/day, lower consumption of carrot & pumpkin (Odds Ratio (OR)=6.67, 95% Confidence Interval (CI)=1.98~22.44), tomato (OR=5.11, 95% CI=1.62~16.08), mandarin & orange (OR=8.64, 95% CI=1.59~46.81), and walnut & pine nut (OR=3.85, 95% CI=1.26~11.77) increased the risk of childhood AD. According to the results, maternal food intakes during pregnancy were significantly different between the AD and non-AD groups. Therefore, further studies are necessary to examine the causal relationship between maternal food intake and prevalence of AD in children.

Breastfeeding has been known as the best feeding practice to prevent allergies including atopic dermatitis (AD) However, the benefit on the prevention of allergic disease is still controversial. The objectives of this study were to examine the rate of sensitization to the protein of eggs, cow's milk and soy in exclusively breastfed infants and to evaluate antigen-antibody reaction between breast milk and serum of AD infant. Data on feeding and food hypersensitivity were obtained for 62 AD infants (32 male, 30 female) aged < 6 month who had visited Samsung Medical Center from September 2001 to May 2003. Food hypersensitivity was determined by measuring specific IgE to egg, cow's milk and soy. Specific IgE levels > 0.7 kU/L by CAP assay (Pharmacia, Uppsala, Sweden) were considered positive. The rates of sensitization in breastfed infants were $41.9\%$ (26/62) to egg, $30.6\%$ (19/62) to milk and $18.0\%$ (11/62) to soy. Immunoblotting analyses were performed using breast milk with the matched serum of seven AD infants (4 male/3 female). Binding patterns of AD infant's IgE to breast milk extract showed visible specific band for immunoglobulin, especially in case of a lactating mother who did not completely restricted ingestion of egg, milk and soy. These results indicate that sensitization to food allergen develops via breast milk feeding. Breast milk feeding should be recommended in infants at risk of developing allergic disease, but maternal intake of highly allergenic food might be restricted for prevention and treatment of food allergy among the babies with AD.

Objectives: This study was performed in order to determine airborne fungi levels in homes and find related factors that may affect airborne fungi concentration. Methods: Fifty homes were study subjects for measuring airborne fungi. For sampling airborne fungi, the impaction method on agar plates was used and samples were counted as colony forming units per cubic meter of air ($CFU/m^3$). In addition, information regarding housing characteristics and atopic disease in each home were collected via questionnaire. Results: The geometric means (GM) of airborne fungi concentrations in fifty living rooms and bedrooms were 68.03 and 62.93 $CFU/m^3$, respectively. The GM of airborne fungi concentration in atopy homes was 78.42 $CFU/m^3$. This was higher than non-atopy homes' 54.34 $CFU/m^3$ (p-value=0.051). In the results of the multiple regression analysis, outdoor airborne fungal concentration proved a strong effective factor on indoor airborne fungal concentration. Also, construction year, floor area of house, indoor smoking and frequency of ventilation were factors that showed a significant association with indoor airborne fungi concentration. Conclusions: The results of this study show that some housing and living characteristics may affect the development and increase of airborne fungi. In addition, exposure to airborne fungi may be a risk factor for the prevalence of childhood atopic diseases.

Objectives : Atopic Dermatitis (AD) is chronic skin disease characterized by allergic hypersensitivity reactions. Samhwangsasim-tang Gamibang(SHSST) can treat skin disease by cooling down blood heat, clearing away congenital fever and detoxicating. This study was conducted to investigate the effects of SHSST on AD induced by oxazolone in mice. Methods : We investigated the effects of SHSST on skin tickness, skin lesions, erythema and melanin index, water content and histopathological changes in vivo. The effects on body weights and spleen body weight ratio were also investigated in mice with AD. Results : In our results, oral administration of SHSST ameliorated skin lesion such as flare, erythema, exudate and petechia and lowered skin thickness induced by oxazolone. In addition, SHSST lowered erythema index and elevated water content compared to AD control respectively. In the histopathological observation, oral administration of SHSST prevented epidermal hyperplasia and spongiotic changes which is a hallmark of skin inflammation respectively. Finally, SHSST did not affect spleen/body weight ratio. Conclusions : These data imply that SHSST can ameliorate skin lesion of AD such as flare, erythema, exudate and petechia, and be used to treat AD patients with relative safety.

Atopic dermatitis(AD) is a chronic disease that affects the skin. "Atopic" refers to a group of diseases where there is often an inherited tendency to develop other allergic conditions, such as asthma and hay fever. In AD, symptoms vary from person to person. The most common symptoms are dry, itchy skin and rashes on the face, inside the elbows and behind the knees, and on the hands and feet. Although AD may occur at any age, it most often begins in infancy and childhood. The cause of AD is not known, but the disease seems to result from a combination of hereditary and environmental factors along with malfunction of the body's immune system. In contrast to that, the results from literatual study in oriental medicine are as follows; 1. The causes of AD are considered to be Mosusigisadok(母受時氣毒), Waegampoongsubyeol(外感風濕熱), Guasiksinlayeolmul(過食辛辣熱物), Ohbokonje(誤服溫劑). 2. The symptoms are fever, flushed face, red eyes, oliguria, constipation and itching. 3. Chungyeolhaedok(淸熱解毒) would be the basic method of treatment, and it divides into two categories; Subhyung(濕型) and Gunhyung(乾型). In Subhyung(濕型), AD is treated by Josub(燥濕), Chungyeol(淸熱) and Jiyang(止痒) whereas Chungyeol(淸熱), Jiyang(止痒), Jesub(除濕) in Gunhyung(乾型). 4. To prevent further damage and enhance quality of life, it is necessary to keep the temperature and humidity favorable, and healing the skin and keeping it healthy are important. Developing and sticking with a daily skin care routine is critical to preventing flares. Changing the diet and psychological stability may also be helpful to relieve symptoms of AD.
