  • The purpose of this study is to examine the current status of allergic diseases associated with the housing environment and the psychological attitude of residents towards relevant risk factors. This study surveyed 1,200 people. In the first round, 200 participants were questioned through direct survey methods, while 1,000 participants filled out an online survey in the second round. Selected study subjects consisted of allergic diseases known to be closely related to housing environment factors. With advice from medical experts, the analysis included the examination of the prevalence status regarding five types of allergy-related diseases-allergic conjunctivitis, allergic rhinitis, allergic dermatitis, asthma and headache-with the range of disease incidence set within the past ten years. The survey was conducted on all age groups except those nine years old and younger, and the findings are as follows. Allergic diseases were found to be more prevalent among women than men. Residents identified effective methods for the alleviation and treatment of allergic diseases as ventilation, use of environmentally-friendly finishing materials, maintenance of a clean living space through cleaning or washing, and sunlight exposure. Residents' understanding of allergic diseases varied depending on their experience with such diseases and residential characteristics.

  • 안토시아닌(anthocyanins)은 플라보노이드에 속하고 항산화 활성들을 포함한 그들의 다양한 건강 유익성에 대해 알려져 있다. 그들 중 검정콩 껍질에서 분리한 주요 안토시아닌은 glycopyranose를 함유하고 있는 배당체이다. 천식은 호염기성 세포(basophils)와 비만세포(mast cells)를 포함한 다양한 면역세포와 관련된 알레르기 관련 질병이다. 호산구(eosinophils), 호염기성 세포, 비만세포는 탈과립화에 의한 천식-특이적 보조 2(T-helper 2) 사이토카인 분비 그리고 계속해서 일어나는 증폭과 같은 염증을 일으키는 매개체의 증가를 통해 알레르기 천식(allergic asthma)에서 중요한 역할을 한다. 흰쥐 호염기성 백혈병(rat basophilic leukemia) RBL-2H3 세포는 알레르기 반응을 측정하기 위해 가장 일반적으로 사용되는 in vitro 모델이다. 본 연구에서는 검정콩 껍질 안토시아닌이 항원으로 자극한 RBL-2H3 세포에서 탈 과립 그리고 Th2 사이토카인 생산에 미치는 효과를 조사하였다. 세포 탈과립은 ${\beta}$-hexosaminidase의 방출을 검출함으로써 평가하였다. IgE-항원 복합체로 자극한 RBL-2H3 세포내 ${\beta}$-hexosaminidase 방출과 Th2 사이토카인 생산이 무처리군의 그것과 비교하여 더 높았다. 안토시아닌은 RBL-2H3 세포의 IgE-항원 복합체 유도 탈과립을 현저하게 억제시켰고 RBL-2H3 세포내 IgE-항원 복합체-매개체 interleukin(IL)-4, IL-13 그리고 TNF-${\alpha}$ 생산을 저해하였다. 이러한 결과는 검정콩 껍질 유래 안토시아닌이 알레르기 반응(allergic reaction)을 현저히 저해하는 효과가 있음을 보였고, 이들 안토시아닌이 향후 알레르기 천식을 억제하거나 개선하는데 유용한 물질로 사용될 가능성이 있을 것으로 판단되었다.

  • Thymic stromal lymphopoietin (TSLP) is a novel interleukin (IL)-7-like cytokine and was originally discovered in the supernatant of a murine thymic stromal cell line. TSLP signal initiates via complex of the TSLP receptor and the IL-7 receptor α chain. TSLP expression is closely connected with many diseases such as atopic dermatitis, allergic rhinitis, asthma, inflammatory arthritis, eosinophilic esophagitis, rheumatoid arthritis, inflammatory bowel diseases, and cancer. In this review, I discussed biological roles of TSLP on mast cell-mediated allergic responses. In addition, this review summarizes the effective drugs in allergic-inflammatory reactions induced by TSLP on mast cells.

  • Allergic inflammation requires the orchestration of altered gene expression in the target tissue and in the infiltrating immune cells. The transcription factor STAT6 is critical in activating cytokine gene expression and cytokine signaling both in the immune cells and in target tissue cells including airway epithelia, keratinocytes and esophageal epithelial cells. STAT6 is activated by the cytokines IL-4 and IL-13 to mediate the pathogenesis of allergic disorders such as asthma, atopic dermatitis, food allergy and eosinophilic esophagitis (EoE). In this review, we summarize the role of STAT6 in allergic diseases, its interaction with the co-factor PARP14 and the molecular mechanisms by which STAT6 and PARP14 regulate gene transcription.

  • Allergy has a born predominant cause of atopy in body and react oversenstively several meterial. The cause of allergy are tick, house dust, egg, milk, bean, cosmetics, virus, bacteria, flesh and meat in Western medicine. While, Oriental medicine did not have an application on the allergy, but recognized that allergy is connected with fetal toxicosis, heat-syndrome in new born, syndrome characterized by dyspnea, sneezing, stuffy nose, nasal discharge and phlegm. Therefor, We knowed method of medical treatment following cause of disease and pathogenesis against allergy. Allergic disease(atopic dermatitis, bronchial asthma, rhinitis) were related with lung, spleen, kidney. To prevent allergic disease in born, Oriental medicine taked a serious view of fetal education. In Western medicine, The cause of allergy applied to exopathogen of Oriental medicine. In Oriental medicine, Treatment of allergy used generally strengthening the body resistance to eliminate pathogenic factors.

  • Objective: Eosinophils are typically characterized by a bilobar nucleus with highly condensed chromatin and cytoplasm containing two major types of granules, specific and primary granules, and lipid bodies. The role of inflammation in asthma and other allergic diseases of the airways is widely appreciated, and airway inflammation is now included as a defining feature of asthma. The importance of the presence of eosinophils in the airways of patients with fetal asthma has long been recognized, but the mechanism by which these cells are recruited and retained in the lungs are only now being elucidated. Eotaxin is a potent and specific eosinophil chemoattractant that is mobilized in the respiratory epithelium after allergic stimulation. Methods : Water extracts of Armeniacae Amarum Semen(AAS) and pulmonary epithelial cell lines A549(alveolar typeII epithelial cells) and human eosinophils were used. Cytotoxic effects of AAS and MIS assay were estimated, as well as the effects of AAS on chemokines from prestimulated A549 cells by sandwich ELISA and RI-PCR. Chemotaxis assay was conducted on prestimulated eosinophils treated with AAS. Results : In this study it is demonstrated that $TGF-{\alpha}$, IL-4 and $IL-1{\beta}$ induced the accumulation of chemokine mRNAs in the alveolar epithelial cell lines A549 in dose-dependent manner. Eotaxin and IL-8 were inhibited by AAS in dose-dependent manner(p<0.05). Eosinophil migration was inhibited at high concentrations of AAS(p<0.05). Conculusions : These findings are indicative of suppression of eotaxin and IL-8, and suggest that this is accomplished through AAS treatment. This raises the possibility that AAS is of therapeutic value in diseases such as asthma.

  • Recent increases of asthma and allergies in childhood made the need for a standardized approach to international and regional comparisons of their prevalence and severity. To address these issues, 'International Study of Asthma and Allergies in Childhood (ISAAC)' is currently underway. In Korea, 'Nationwide Study of Asthma and Allergies in Korean Children' began in 1995 according to ISAAC protocol. ISAAC written and video questionnaires were used in this survey, but their reliability and validity were not evaluated properly yet. In this study, our aim was to evaluate the reliability and validity of two kinds of questionnaires and their usefulness in international and regional comparisons. The test and retest of two questionniares were completed by male(n=110) and female(n=111) middle school students with two and three weeks interval each. Kappa(or weighted kappa) were calculated from each questions and validity coefficients were estimated from those statistics. In Korean version of written questionnaire, the questions for allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and food allergy proved to have high kappa values (or weighted kappa values) and validity coefficients and they can be used in further studies without any correction. But some questions about asthma(especially nocturnal cough, wheezing in exercise, and severe asthma) and drug allergy need to be revised for better under-standing to study subjects. Video questionnaire has the same degree of reliability and validity when compared to written questionnaire and this is the unexpected result. Accordingly, it also need to be revised to overcome the racial and cultural differences of the study subjects. In conclusion, the Korean version of written and video questionnaires may be considered to be useful methods in international and regional comparisons of asthma and allergic diseases in childhood after correction of some questions.

  • It has been reported that Bopheyangyoungjeon(BYJ) has an effect on deficiency asthma(喘虛) clinically. The aim of this study was to determine an appropriate dosage of BYJ to treat asthma. In order to study the effects of orally administered BYJ on allergic asthma, mice were pretreated with three oral doses of the herbal solution of BYJ before antigen sensitization. 2 days later Mice were actively sensitized with a subcutaneous injection of ovalbumin and 13 day later ovalbumin aerosols were used to provoke asthmatic reaction. Serum level of IgE, IL-4, WBC, RBC, HGB, cell numbers in bronchoalveolar lavage fluid(BALF), and in vitro isometric contractile responses of the isolated tracheal smooth muscle(TSM) to acetylcholine(ACh, 0.1-1000uM), KCl were measured. The results were as follows ; 1. Contractile responses of TSM to ACh significantly increased in C group at Ach 0.3, 1, 3, 10, 30, 100, 300, 1000uM(P<0.05, P<0.01) and increased in D at 0.1, 0.3, 3, 30, 30, 100, 300, 1000uM. 2. The sensitivity of TSM to Ach increased more in A, B group, but it was not significant. 3. The maximal contractile response of TSM to ACh decreased more significantly in C group(P<0.01) and D group(P<0.05) the control group. 4. The maximal contractile response of TSM to KCI decreased more significantly in B group and C group(P<0.001) than in the control group. 5. The counts of lymphocytes in BALF decreased more significantly in B group and D group(P<0.05) than in the control group. 6. The counts of macrophages in BALF decreased more significantly in B group, C(P<0.05) than in the control group. 8. Serum IgE level increased more significantly in B group and C group(P<0.05) than the control group. 9. The counts of WBC, RBC, HGB in blood increased more significantly in A group than the control group. The above results support a role for BYJ orally administered in treatment of deficiency allergic Asthma.
