  • Purpose: In addition to regulating calcium and phosphorus homeostasis and bone metabolism, vitamin D is known as an immune modulator. Recently, there has been increased worldwide interest in the association between low levels of vitamin D and allergic diseases. The purpose of this study was to assess the relationship between serum vitamin D levels and allergic/vasomotor rhinitis (AR/VR) in children. Methods: This study included 164 patients. The sample included 59 patients with AR, 42 patients with VR, and 63 controls. Their ages ranged from 0 to 16 years. We examined the levels of 25-hydroxyvitamin D, Immunoglobulin E, specific IgE, and eosinophil cationic protein; peripheral blood eosinophil count; and the results of a skin prick test. Results: Serum 25-hydroxyvitamin D levels were $19.0{\pm}8.5ng/mL$ in the AR group, $25.5{\pm}10.9ng/mL$ in the VR group, and $26.9{\pm}10.7ng/mL$ in the control group. After adjustment for body mass index and season at the time of blood sampling, vitamin D levels in the AR group were lower than those of the VR group (P=0.003) and control group (P<0.001). Vitamin D levels were inversely correlated with Immunoglobulin E levels (r=-0.317, P<0.001). AR patients with food allergy or atopic dermatitis did not have lower levels of 25-hydroxyvitamin D than AR patients without these diseases. Conclusion: This study demonstrates a possible relationship between vitamin D levels and allergic rhinitis in Korean children.

  • Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity lung disease due to bronchial colonization of Aspergillus fumigatus that occurs in susceptible patients with asthma or cystic fibrosis. A 10-year-old girl was referred to the Department of Pediatric Pulmonology for persistent consolidations on chest radiography. Pulmonary consolidations were observed in the right upper and left lower lobes and were not resolved with a 4-week prescription of broad-spectrum antibiotics. The patient had a history of atopic dermatitis and allergic rhinitis but no history of asthma. She had no fever but produced thick and greenish sputum. Her breathing sounds were clear. On laboratory testing, her total blood eosinophil count was $1,412/mm^3$ and total serum IgE level was 2,200 kU/L. Aspergillus was isolated in the sputum culture. The A. fumigatus-specific IgE level was 15.4 kU/L, and the Aspergillus antibody test was also positive. A chest computed tomography scan demonstrated bronchial wall thickening and consolidation without bronchiectasis. An antifungal agent was added but resulted in no improvement of pulmonary consolidations after 3 weeks. Pulmonary function test was normal. Methacholine provocation test was performed, revealing bronchial hyperreactivity ($PC_{20}=5.31mg/mL$). Although the patient had no history of asthma or bronchiectasis, ABPA-seropositivity was suspected. Oral prednisolone (1 mg/kg/day) combined with antifungal therapy was started. Pulmonary consolidations began decreasing after 1 week of treatment and completely resolved after 1 month. This is the first observed and treated case of seropositive ABPA in Korean children without previously documented asthma.

  • Sinichengpaeum has been widely used in the oriental medical treatment of nasal diseases. These studies were performed done to investigate the effect of Sinicheng- paeum on the anti-allergic action We studied the vascular permeability response induced by the histamine and serotonin injection(allergy Ⅰ type), homologous PCA provoked by the IgE-like antibody against EWA(allergy Ⅳ type), contact dermatitis induced by picryl chloride(allergy Ⅳ type), delayed type hypersensitivity response to SRBC (allergy Ⅳ type), and the amount of eosinophil and IgE. The results were as follows: 1. The effect of Sinichengpaeum on vascular permeability responses to intradermal histamine and serotonin were significant. 2. In the homologous PCA provoked by the IgE-like antibody against white egg albumin, Sinichengpaeum showed a significant effect. 3. In the delayed type hypersensitivity responses to picryl chloride, Sini-chengpaeum provoked a significant effect. 4. After reaction provoked by picryl chloride, Sinichengpaeum showed an insignficant effect on amount of eosinophil, but a significant effect in IgE amount. 5. In the delayed type hypersensitivity responses to SRBC, Sinichengpaeum provoked a significant effect. 6. After reaction provoked by SRBC, Sinichengpaeum showed a significant effect on amount of cosinophil, but an insignificant effect in IgE amount.

  • Objective : Active treatment for a skin condition has produced a substantial change in the history of allergic contact or wound induced dermatitis. The frequency of opportunistic contacts and allergen-related dermatitis has increased, though new skin treatments have developed. Especially, there has been a interest in the korean herbal bathing. This study was performed to investigate the effects of the korean herbal bathing candidates on skin lesions in mice model. These candidates are Korea's representative herbs on skin lesions. Method : ICR mice were divided into five groups : naive, control, experimental group A and B and C. Control and experimental groups induced skin lesions by DNFB and TMA. Each experimental group was pasted with corresponding korean herbal bathing candidates on skin lesions. Result : Significant improvements in skin wound index, epidermal thickness associated with skin lesions were seen with the korean herbal bathing candidates. Conclusion : These results suggest that the korean herbal bathing candidates could be at least as effective as steroid, anti-histamine for the treatment of skin lesions.

  • Food allergy is an important public health problem affecting 5% of infants and children in Korea. Food allergy is defined as an immune response triggered by food proteins. Food allergy is highly associated with atopic dermatitis and is one of the most common triggers of potentially fatal anaphylaxis in the community. Sensitization to food allergens can occur in the gastrointestinal tract (class 1 food allergy) or as a consequence of cross reactivity to structurally homologous inhalant allergens (class 2 food allergy). Allergenicity of food is largely determined by structural aspects, including cross-reactivity and reduced or enhanced allergenicity with cooking that convey allergenic characteristics to food. Management of food allergy currently focuses on dietary avoidance of the offending foods, prompt recognition and treatment of allergic reactions, and nutritional support. This review includes definitions and examines the prevalence and management of food allergies and the characteristics of food allergens.

  • 본 연구는 DNCB로 유도한 아토피 피부염 유사 병변 실험동물 모델을 활용한 in vivo와 피부 각질세포주를 이용한 in vitro 연구를 통하여 아로니아와 모링가 종자 추출물의 아토피 피부염 개선 효능을 분석하였다. 조직학적 검사 결과 아로니아 추출물(AM) 또는 모링가 종자 추출물(MO) 단독 투여 시보다 1:1로 혼합한 복합물(AM-MO)을 투여했을 때 표피 부분의 과증식과 염증세포의 침윤이 감소하였으며, 염증 및 부종을 나타내는 피부 두께를 측정한 결과에서도 추출물 단독으로 투여하였을 때보다 AM-MO 투여 시 DNCB 도포군과 비교하여 유의하게 감소함을 보여주었다. 피부장벽 손상으로 인한 수분 손실에 대해서는 유의한 효과를 나타내지 않았으며, 혈청 IgE 수준은 AM과 MO 각각 단독으로 투여했을 때보다 혼합 투여하였을 때 현저하게 억제되었다. In vitro에서는 피부각질세포주인 HaCaT 세포를 $TNF-{\alpha}$$IFN-{\gamma}$로 자극하면 발현이 증가하는 Th2 케모카인 TARC 및 MDC에 대하여 mRNA 수준을 분석하였을 때, 이 역시 단독 추출물 처리 시보다 복합물 처리 시 억제 효과가 더 뛰어남을 확인하였다. 종합적으로 DNCB로 유도된 아토피 피부염 in vivo 모델에서 아로니아 및 모링가 종자 추출물은 단독으로 투여하는 것보다 복합물로 투여하였을 때 현저하게 피부 염증 및 혈청 내 IgE 생성을 억제하였으며, 피부각질 세포주를 이용한 in vitro 연구에서도 추출물 단독 처리보다 혼합하여 처리하였을 때 더 유의한 Th2 케모카인 억제 활성을 나타내었다. 이로 인해 아로니아 및 모링가 종자 추출물은 복합적으로 사용하였을 때 상호작용에 의해서 더 효과적인 아토피 피부염 개선 식품 소재로써 활용될 가능성이 높을 것으로 생각된다.

  • Purpose: Atopic dermatitis (AD) is a chronic inflammatory relapsing skin disorder. Vitamin D plays a pivotal role in the development of AD, and interleukin (IL) 31 is known to be related to pruritus in AD. The aim of our study was to determine whether 25-hydroxyvitamin D (25(OH)D) levels are related to IL-31 levels or to the severity of AD. Methods: We enrolled 91 children with AD and 32 control subjects without history or symptoms of allergic diseases. Blood was drawn to evaluate complete blood cell count, total eosinophil count (TEC), and total IgE, specific IgE to common allergens, 25(OH)D, and IL-31 levels. Serum 25(OH)D and IL-31 levels were measured using high-performance liquid chromatography and enzyme-linked immunosorbent assay, respectively. The scoring atopic dermatitis (SCORAD) index was used to evaluate the severity of AD. Results: The mean 25(OH)D level was significantly lower in the AD group than in the control group; 25(OH)D decreased greatly in the moderate and severe AD groups compared with the mild AD group. Children with atopic sensitization showed significantly lower 25(OH)D levels than nonatopic children. However, serum IL-31 levels were not related to AD group, SCORAD index, or 25(OH)D levels. The SCORAD index was inversely correlated with serum 25(OH)D level and positively correlated with TECs and total IgE levels. Children with moderate and severe AD had significantly higher TECs than children with mild AD. Conclusion: Vitamin D is related to the severity of AD independently of IL-31.

  • CRTh2 receptor is an important mediator of the inflammatory effects and act as beneficial target for the treatment of asthma, COPD, allergic rhinitis and atopic dermatitis. In the present work, Hologram QSAR studies were conducted on a series of 50 training set CRTh2 antagonists (2-(2-(benzylthio)-1H-benzo[d]imidazol-1-yl acetic acids). The best HQSAR model was obtained using atoms, bonds, connections and donor/acceptor as fragment distinction parameter using hologram length 257 and 6 components with fragment size of minimum 7 and maximum 10. Significant cross-validated correlation coefficient ($q^2=0.786$) and non cross-validated correlation coefficients ($r^2=0.954$) were obtained. The model was then used to evaluate the 15 external test compounds which are not included in the training set and the predicted values were in good agreement with the experimental results ($r^2_{pred}=0.739$). Contribution map show that presence of C ring and its substituents makes big contributions for activities. The HQSAR model and analysis from the contribution map could be useful for further design of novel structurally related CRTh2 antagonists.
