Aspirin-intolerant asthma (AIA) is characterized by severe asthmatic attack after ingestion of aspirin and/or non-steroidal anti-inflammatory drugs. In this study, we investigated the relationship between Prostaglandin E2 receptor (PTGER) gene family polymorphisms and AIA in 243 AIA patients and 919 aspirin-tolerant asthma (ATA) controls of Korean ethnicity in two separate study cohorts. After genotyping 120 SNPs of the PTGER gene family for the $1^{st}$ cohort study, four SNPs in PTGER1, ten in PTGER3, six in PTGER3, and a haplotype of PTGER2 showed association signals with decreased or increased risk of AIA. Among the positively associated SNPs, one in PTGER1 and four in PTGER3 were analyzed in the $2^{nd}$ cohort study. The results show that rs7543182 and rs959 in PTGER3 retained their effect, although no statistical significance was retained in the $2^{nd}$ cohort study. Our findings provide further evidence that polymorphisms in PTGER3 might play a significant role in aspirin hypersensitivity among Korean asthmatics.

본 연구에서 저알레르기 처리 공정은 Autoclaving, 가열처리, micro wave, dry heating, 초음파, 효소, 인산염, 천연효소, 가용화, 복합처리 등의 처리 공정으로 하였다. 저 allergy처리에서 allergy가 완전히 억제되는 것은 가열처리를 한 것으로 쇄양 B(추출액+가열 3분), autoclave 처리, micro파 처리, dry heating처리, 복합처리를 했을 때이다. 또한 천연효소(키위)를 침지한 후 tolergen과 같이 3분간 가열했을 때 allergy가 억제되는 것으로 나타났다. 즉 가열처리로 인한 단백질 구조 변성으로 이러한 결과를 보인 것으로 보인다. 인산염의 경우도 어느 정도 억제가 되는 것으로 보이고 있다. 나머지 처리들은 거의 효과를 보이고 있지 않다. 천연효소와 tolergen(쇄양)을 그냥 처리했을 때에는 allergy 억제효과는 없는 것으로 나타났다. 우유의 저 allergy 처리는 효소, autoclave, micro 파, NaOH 처리, 복합처리에서 감소되는 것으로 나타났다. 이러한 결과는 western blotting으로도 확인되었으며 그 억제율 %은 식육에서는 상당한 가열처리를 통하여 알레르기를 감소시킬 수 있는 것을 볼 수 있으며 또한 인산염, 가용화(NaOH처리)도 저 알레르기 효과가 있음을 알 수 있다. 키위, 쇄양 단독 처리 시 저 알레르기 효과가 없지만 약간의 가열을 통하여 알레르기가 감소됨을 알 수 있다. 우유는 효소나 autoclave 처리만이 저 allergy 효과가 각각 28%, 45%로 적게 나타났다. 모든 복합처리의 경우에서는 그 억제율이 41-96%로 높은 효과가 있음을 알 수 있다. 천연효소처리와 인산염 처리된 식육의 전자현미경적 관찰은 control과 비교시 조직의 변화가 없고 둘다 근육 단백질 구조를 분산시키는 것으로 나타났다. 또한 고기를 단계별 복합처리로 저 allergy 처리는 단계별로 점차적으로 allergy가 감소되었다. 즉 단계별로 억제가 안되는 것부터 억제되는 처리를 복합적으로 처리한 것으로 그 단계는 천연효소처리에 인산염 처리, 여기에 초음파 처리, 마지막 단계로 3분 끓이면 억제율이 68%까지 억제되었다. 이는 단일처리시 전혀 억제를 못하는 처리를 단계별로 한 단계씩 더해가면 allergy 억제효과가 나타난다고 할 수 있겠다. 초음파 처리도 역시 저 allergy 처리 공정에 이용될 수 있는데 이것은 그 처리로 인해 새로운 알러젠이 생성될 수도 있다. 또한 복합처리로 allergy를 감소시키면 연속적이고 동시적으로 하기 때문에 원가를 절감할 수 있다.

According to the hygiene hypothesis, westernized and urbanized life style leads to the increase of allergic disease. This hypothesis supports the use of probiotic therapy for the prevention or treatment of food allergy. The probiotics which contains potentially beneficial microorganism have been used for the treatment of some gastrointestinal disorders and atopic disease as dietary supplements. Many results of studies support the immunologic bases of probiotics therapy. The most important mechanism is that probiotics suppress Th2-skewed immunity as the stimulation of regulatory T cell. The difficulties of diagnosis of food allergy, variable symptoms, many kinds of microorganism, diet style and non-standardized study designs are attributed to the variety and controversy of the effectiveness of probiotics in food allergy with infant and children. More studies is needed to confirm the efficacy of probiotics in infant and children with food allergy.

Although there has been a steady increase in the prevalence of food allergies worldwide in recent decades, no effective therapeutic strategies have been developed. Modulation of the gut microbiota composition and/or function through probiotics has been highlighted as a promising target for protection against food allergies. In this study, we aimed to investigate the allergy-reducing effects of a probiotic mixture (P5: Lactococcus lactis KF140, Pediococcus pentosaceus KF159, Lactobacillus pentosus KF340, Lactobacillus paracasei 698, and Bacillus amyloliquefaciens 26N) in mice with ovalbumin (OVA)-induced food allergy. Administration of P5 significantly suppressed the oral OVA challenge-induced anaphylactic response and rectal temperature decline, and reduced diarrhea symptoms. Moreover, P5 also significantly inhibited the secretion of IgE, Th2 cytokines (interleukin (IL)-4, IL-5, IL-10, and IL-13), and Th17 cytokines (IL-17), which were increased in mice with OVA-induced food allergy, and induced generation of CD4+Foxp3+ regulatory T cells. These results revealed that P5 may have applications as a preventive agent against food allergy.

결핵균은 공기를 매개로 전파되고 결핵균에 노출된 시간과 최초의 노출 정도가 전파의 위험을 증가 시키는 중요한 인자로 알려져 있다. 활동성 폐결핵 환자와 함께 생활하는 가족 내에서 감염이 현저히 증가하는데 이는 결핵균에 노출되는 기회 및 시간이 증가하기 때문이다. 하지만 고식적인 접촉자 조사만으로는 흔히 결핵 발생률을 과소평가할 수 있기 때문에 접촉자 조사와 결핵균의 유전형 조사를 병행하는 것이 감염의 위험이 높은 집단을 선별해내고 발생빈도 및 전염경로를 밝히는 데 보다 효과적인 것으로 보고되고 있다. 이에 접촉자 조사와 결핵균의 유전형 조사를 통해 가족 내 결핵균 전파를 증명한 1예를 보고하는 바이다.

Food allergy refers to an immunologically mediated adverse reaction to food, mainly to proteinaceous constituents. Health implications vary between those individuals who experience mild physical discomforts to those with fast-acting, life-threatening anaphylactic reactions. The prevalence of food allergy is higher in children than in adults, estimated around 4-8% and 1-2% respectively in developed countries. Food allergy has no effective cure at the present time and total avoidance of causative foods is the most reliable prophylactic method currently recommended by the medical community. To help food allergic patients to make informed choices of their foods, mandatory labeling of selected food allergens has been introduced in several countries. All food allergen labelling provisions specify a set of allergens common to the regulated countries. Policy divergence, however, exists between countries by inclusion of additional allergens unique to specific countries and enforcement of specific labelling requirements. Such variations in food allergen labelling regulations make it difficult to manage allergen labeling in imported pre-packaged food products. This paper addresses two current issues in food allergen regulation: 1) an urgent need to determine true prevalence of food allergy in the Asia-Pacific region. This will enable refinement to the food allergen regulation to be more country-specific rather than simply adopting CODEX recommendations. 2) There is an urgent need for harmonization of food allergen regulation in order to prevent food allergen regulation becoming a trade barrier.

Objective: The purpose of this study was to develop a standard tool for pattern identification of radiation pneumonitis. Methods: Textbooks, published studies, and references with comments about patterns were reviewed. Through the Delphi method, we determined pattern identifications based on advice from a committee of experts composed of 13 Korean respiratory internal medicine professors. Results: Using the Delphi method, four pattern identifications were chosen: Qi Deficiency (氣虛), Yin Deficiency (陰虛), Heat Toxin (熱毒), and Phlegm Dampness (痰濕). The tool was developed in a question-and-answer format with 35 questions. Conclusions: A pattern identification tool that can discriminate the patterns of radiation pneumonitis for standardized diagnosis was developed through expert consultation. Further study of its validity and reliability is necessary.

Objective : Atopic dermatitis is a chronic, inflammatory skin disease which was characterized by intense pruritus and the course marked by exacerbation and remission. The purpose of this study is to report the effect of oriental treatment. Especially new oriental prescription to atopic dermatitis Methods : We treated children patients who had atopic dermatitis and visited oriental hospital of Semyung University. Children patients in this case are two person. The first one is fourteen-years-old female, Other one is seven-years-old boy. And I create a new oriental prescription that named 'Allergy 1' thinking about oriental theory. After then I treated them with 'Allergy 1' herb medication and used two index to assess the severity in atopic dermatitis. Results : Each index show us approximately 70% improvement in atopic dermatitis symptom. Conclusion : On the basis of this cases, It may be considered that treatment of atopic dermatitis should be improved by the treatment of herb medication "Allergy 1"

Hematemesis is a rare condition in infants and can be a symptom of cow's milk-induced hemorrhagic gastritis. Other clinical manifestations of cow's milk allergy are vomiting, malnutrition and anemia. The criteria for the diagnosis of cow's milk allergy includes elimination of cow milk formula resulting in improvement of symptoms, specific endoscopic and histologic findings as well as exclusion of other causes. Cow's milk allergy should be considered in the etiologic differential diagnosis of hematemesis and gastritis in infancy. We have experienced a 1-month-old female infant with hematemesis due to cow's milk-induced hemorrhagic gastritis, and report the case with a review of previously published cases.
