  • In recent years, the safety of sunscreens have been challenged based on the reports of its adverse effects on users; dermatitis, allergic contact dermatitis, photoallergic contact dermatitis. In the toxicological aspect, the need to investigate the safety of sunscreens is steadily increasing. However, there were few studies on the correlation between sun protection factor (SPF) and the safety of sunscreens. The objective of this study was to assess whether there was a correlation between SPF and the skin irritation index of sunscreens. Octyl methoxycinnamate (OMC) was selected, which was the most frequently used (about 92% in korea and about 90% in the world) in sunscreens. In vitro SPF test was performed using the standard samples recommended by KFDA guideline. We examined primary and cumulative skin irritation and eye irritation of OMC standard sample as well as homosalate. As in vitro SPF was increased, skin irritation index was increased in primary skin irritation test ($r^2$=0.986) and cumulative skin irritation test ($r^2$=0.939). In addition, OMC was non-irritating and non-sensitizing. In this results, there was a good correlation between SPF index and skin irritation index.

  • Previous infant feeding guidelines recommended a delayed introduction of solids to beyond 6 months of age to prevent atopic diseases. However, scientific evidence supporting a delayed introduction of solids for prevention of atopic diseases is scarce and inconsistent. Current evidence does not support a major role for maternal dietary restrictions during pregnancy or lactation in the prevention of atopic disease. In studies of infants at high risk of developing atopic disease, there is evidence that exclusive breastfeeding for at least 4 months compared with feeding intact cow milk protein decreases the incidence of atopic dermatitis, cow milk allergy, and wheezing in early childhood. For infants at high risk of developing atopic disease who are not breastfed exclusively for 4 to 6 months, there is modest evidence that atopic dermatitis may be delayed or prevented by the use of extensively or partially hydrolyzed formulas, compared with cow milk formula, in early childhood. There is no convincing evidence that a delayed introduction of solid foods beyond 4 to 6 months of age prevents the development of atopic disease. For infants after 4 to 6 months of age, there are insufficient data to support a protective effect of any dietary intervention for the development of atopic disease.

  • Purpose: This study was done to estimate the prevalence of atopic dermatitis (AD) and its risk factors for AD in children living in the community. Method: Random samples of 10,236 were selected from 43 kindergarten (1,418) and 57 elementary (8,718) students in K city. Data from 1,079 (kindergarten children) and 7,271 (elementary) students were used in the final analysis. The Korean-translated modified version of the International Study of Asthma and Allergies in Childhood (ISSAC) questionnaire was used in this cross-sectional survey. Parents answered the survey questionnaire. Results: The lifetime and last 12-month prevalence of AD were 40.15%; 30.86% in kindergarten children and 33.56%; 25.37% in elementary children. The lifetime and last 12-month prevalence of AD diagnosis were 40.8%; 18.68% in kindergarten children and 34.36%; 12.63% in elementary children. The lifetime prevalence of AD treatment was 25.93% in kindergarten children and 22.07% in elementary children. Multivariate logistic regression analysis revealed that risk factors for AD were age, allergic disease, age of house, carpets, pets. Conclusion: The study suggests that prevalence of AD has increased among children in the community. These data can be used to manage possible risk factors that are predictors of childhood AD.

  • "Chimumchang" seems to be a kind eczema. The cause and symptom of eczema is similar to that of chimumchang. so, I investigated the literatures of oriental medicin and recent medicine. The results are summarized as follows. 1. Chimumchang seems to be a kind of eczema. Allergic contact dermatitis, atopic dermatitis, seborrheic dermatits, neurodermatitis, nummular dermatitis, xerotic eczema and so on are similar to chimumchang on cause & symptom. 2. The cause of chimumchang are summer vital energy excess(夏脈太過), sehwa excess(歲火太過), herat meridian wind-heat(心經風熱), heart fire(心火), wind taken spleen dampnees(脾濕受風), and so on. The cause of eczema are contact of external agent, immunological problem, heridity, infection, abnormalities of sebaceous glands, neurologic dysfuction, and so on. 3. The symptoms of chimumchang have been described to the three pattern on literature of oriental medicine until now. 1) scratching slightly, It has exudation, and combination. 2) Vital energy on skin is irritable by psychological problem. At the acute stage the patient is complain of itching & pain, and gradually the exudation expands in whole body. 3) early peorid it's size is very small, and at first the patient is complain of itching, later complain of pain. The exudation change to ulcer and expands in the whole body. 4. In the investigation of prescription(Total: 34, Oral medicine: 4, Ointment: 30), the most frequently used oral medicine is sungmatang(4 times), and the most frequently used ointment are kohosan, korvunsan and kegwanhyuldobang.

  • The aim of this study was to investigate the effects of several herbal prescriptions in patients with allergy or atopic disease, such as atopic dermatitis, asthma and allergy rhinitis and others, on the blood immunological parameters and to verify the safety of long-term use of herbal medicine. Eighty one patients with allergy or atopy disease who taken herbal medicine at least for 2 months were compared with patients who taken same medicine with no allergy & atopy disease (n=14) and normal healthy subjects (n=22). According to the comparison of immunological parameters change, the data showed that herbal medicine decreased IgE (P=0.003), Eosinophil ratio (P<0.001) and count (P<0.001) of White Blood Cell (WBC) and did not affect to the liver cell enzymes in blood. This results indicated that herbal medicine decreased immune hypersensitivity and improved chronic inflammation related to blood immunological parameters of allergy or atopy diseases. In addition, herbal medicine seemed to be safe to the liver function for long-term use.

  • Objectives : The aim of this study is to report the effect of Capsosiphon fulvescens(Maesangi) extract(MSE) on contact dermatitis(CD). Methods : CD induced by Dermatophagoides farinae body(Dfb) in NC/Nga mice. 4% sodium dodecyl sulfate(SDS) $150{\mu}l$ and Dfb(10mg/ml) ointment 100mg were topically treated twice a week for four weeks. MSE 200 mg/kg was topically treated every 4weeks. Every week, we examined the skin lesions, weight of spleen and lymph node, epidermal thickness, production of Tumor necrosis factor-alpha($TNF-{\alpha}$) and interleukin-6(IL-6). Results : MSE reduced features of Dfb-induced skin lesions, weight of spleen and production of $TNF-{\alpha}$. MSE significantly reduced weight of lymph node, epidermal thickness, number of mast cells and production of IL-6. Conclusions : MSE may have a potential therapeutic effects for CD by suppressing allergic inflammation.

  • Atopic dermatitis (AD) is an allergic and inflammatory skin. Recently, the limitations and side effects of drug therapy, and possibility of alternative therapies, such as music therapy are emerging in the treatment of AD. Thus, the present study determined whether traditional Korean music, Daegeum Sanjo, regulates AD symptoms by comparing the rhythm, Jinyangjo-jangdan and Jungmori-jangdan in an AD-like murine model. Jinyangjo-jangdan and Jungmori-jangdan of Daegeum Sanjo reduced the duration of scratching behavior increased by DNFB challenge. Jinyangjo-jangdan and Jungmori-jangdan of Daegeum Sanjo attenuated clinical symptoms. However, Jinyangjo-jangdan and Jungmori-jangdan of Daegeum Sanjo did not inhibit IgE, histamine, interleukin (IL)-4, IL-6, or thymic stromal lymphopoietin levels in serum or AD-like skin lesions. In conclusion, the present study suggests that it is possible for Jinyangjo-jangdan and Jungmori-jangdan of Daegeum Sanjo to ameliorate AD symptoms. However, further study is needed to clarify significant mechanisms of Jinyangjo-jangdan and Jungmori-jangdan of Daegeum Sanjo therapy for AD symptoms.

  • Lactococcus lactis is a lactic acid bacterium and used in the dairy food industry. The ameliorating effects of Lactobacillus species on atopic dermatitis (AD) have been extensively studied, but the specific effect of L. lactis strains has not yet been investigated. In this study, the efficacy of L. lactis LB 1022, isolated from natural cheese, was evaluated using RAW 264.7, HMC-1 and HaCaT cell lines and an ovalbumin-sensitized AD mouse model. L. lactis LB 1022 exhibited nitric oxide suppression and anti-allergy and anti-inflammatory activity in vitro. Oral administration of L. lactis LB 1022 to AD mice significantly reduced the levels of IgE, mast cells, and eosinophils, and a range of T cell-mediated T helper Th1, Th2, and Th17-type cytokines under interleukin (IL)-10, transforming growth factor-β (TGF-β), thymus and activation-regulated chemokine (TARC), and thymic stromal lymphopoietin (TSLP). In addition, L. lactis LB 1022 treatment increased the concentration of short-chain fatty acids. Overall, L. lactis LB 1022 significantly modulated AD-like symptoms by altering metabolites and the immune response, illustrating its potential as candidate for use in functional food supplements to alleviate AD.

  • House dust mite (HDM) is important in the pathogenesis of allergic diseases including asthma and atopic dermatitis. Dermatophagoides pteronissinus (Dp) is one of major HDM allergens. In this study, we investigated that Dp extract (DpE) affects on the chemotactic activity of monocytes isolated from the peripheral blood. DpE inhibited the migration of human monocytes in response to CC chemokines such as MIP-$1{\alpha}$, RANTES, HCC-4, MCP-1, and TARC. DpE did not alter the expression of CC chemokine receptors (CCRs) such as CCR1, CCR2, CCR3, CCR4, and CCR5. These results indicate that DpE blocks the chemotaxis of human monocytes and its mechanism is not involved in alteration of CCR expression. Better understanding of the effect of DpE on monocytes will enable elucidation of the role of Dp in the development of allergic diseases.
