The purpose of this study was to determined the rate of sensitization to food allergen in children with Atopic Dermatitis (AD) in Korea. A total of 3,783 patients (male = 1983, female = 1800) with AD (age under 18 years) who had visited Samsung Medical Center from 1998 to 2003 were enrolled in the study. Food hypersensitivity was measured by specific IgE to egg, cow's milk, soy, peanut, wheat, buckwheat, beef, pork, chicken, shrimp, crab, salmon, mackerel, etc. Specific IgE levels > 0.7 kU/L. by Captured Allergen Product (CAP) assay were considered positive. Chi-square test at p value < 0.05 was used to examine the difference of the prevalence by sex and age. The rate of sensitization to multiple food allergens was 31.2% and decreased with age. Hypersensitivity to egg showed highest prevalence, which was 24.3%, compared to the prevalence of other foods. High prevalence of hypersensitivity to milk. wheat, soy, peanut, crab or shrimp was observed (11.6- 17.7%). Low prevalence of hypersensitivity to beef, pork, tuna or chicken was observed (1.9-3.5%). Children aged under 3 years had significantly higher prevalence of hypersensitivity to egg, milk, soy and beef than children aged at least 3 years. Our results stress the need for examination of food hypersensitivity aimed at identified and limited each food allergen among children with AD caused by food to help patients outgrow their food allergy.

한국산 감잎으로부터 폴리페놀 화합물군을 분리하여 알레르기성 접촉피부염에 미치는 영향을 관찰하였다. 그 결과 대조군에 비해 폴리페놀 화합물군에서 era swelling이 감소되었으며, 비만세포의 분포에서도 대조군에 비하여 감잎 폴리페놀 화합물 투여군에서 매우 적은 수가 확인되었으며, 이러한 결과는 제4형 알레르기 반응을 지연 또는 예방할 수 있는 생약제로서의 가능성을 시시하는 것으로 보여진다.

Erythrosine used as a colouring agent in drugs, cosmetics and foods in Korea, was examined for its effects on murine immune system and methemoglobin formation. As immunotoxicologic assay parameters, we adopted circulating leukocytes and immunoorgan weights for pathotoxicology, IgM plaque forming cells and arthus reaction for humoral immunity, delayed hypersensitivity reaction of cell mediated immunity and carbon clearacnce for macrophage function. Erythrosine's effects were observed as follows; 1. Ery throsine showed no significant effects on circulating leulocyte counts and relative immunoorgan weight. 2. Erythrosine diminished IgM plaque forming cells. 3. Erythrosine decreased arthus reaction, in the dose dependent manner. 4. Erythrosine had no significant effect on delayed hypersensitivity. 5. Phagocytic and corrected phagocytic index were not affected. 6. Methemoglobin content was similar in the test and control groups.

황산화제인 Propyl gallate가 in vivo에서 정상 웅성 마우스이 세포 면역기능에 미치는 영향에 관한 실험 결과, 1. Propyl gallate는 지연형과민증을 용량의존적으로 감소시켰다. 2. Phagocitic index와 corrected phagocytic index는 Propyl gallate의 영향을 볼수 없었다. 3. Propyl gallate는 혈중 백혈구 수를 용량의존적으로 감소시켰다.

5가지 식용식물인 신이(Flos magnoliae), 지실(Poncirus trifoliata), 시호(Bupleurum falcatum), 황금(Scutellaria baicalensis), 및 오미자(Schisandra chinensis)의 열수 추출물(10 mg/20 g B.W.)이 제IV형 알레르기 반응에 미치는 억제효과를 관찰하기 위하여 DNFB로 감작된 6주령의 웅성 BALB/C mouse에 1, 2차 시료를 투여한 후, 유도된 접촉성 피부염에 의한 부종도를 측정하였으며 대조 약물로는 cyclosporin(0.005 mg/20 g B.W)을 사용하였다. DNFB의 피부염증반응에 대한 귀 두께 측정은 1차 감작에서 황금, 오미자, 지실 군이 대조 군에 비하여 유의한 감소를 나타냈고(p<0.05), 약물 대조군인 cyclosporin과 같은 억제효과를 보였다. 시호, 신이 군은 대조 군에 비해 감소하는 경향을 보였으나 유의한 차이는 없었다. 억제 효과는 황금>오미자>지실>시호>신이의 순으로서 황금 군의 활성이 가장 높았다. 2차 감작에서는 오미자, 지실, 황금, 신이 군이 대조 군에 비하여 유의한 감소를 나타냈고 오미자와 지실은 약물 대조군인 cyclosporin과는 유의적인 차이는 없었지만 억제 효과가 더 컸다. 시호군은 대조 군과 유의적인 차이가 없었으며 오미자>지실>황금>신이>시호의 순으로서 오미자 군이 가장 높은 억제효과를 나타냈다.

Due to the increasing prevalence and number of life-threatening cases, food allergy has emerged as a major health concern. The classic immune response seen during food allergy is allergen-specific IgE sensitization and hypersensitivity reactions to foods occur in the effector phase with often severe and deleterious outcomes. Recent research has advanced understanding of the immunological mechanisms occurring during the effector phase of allergic reactions to ingested food. Therefore, this review will not only cover the mucosal immune system of the gastrointestinal tract and the immunological mechanisms underlying IgE-mediated food allergy, but will also introduce cells recently identified to have a role in the hypersensitivity reaction to food allergens. These include IL-9 producing mucosal mast cells (MMC9s) and type 2 innate lymphoid cells (ILC2s). The involvement of these cell types in potentiating the type 2 immune response and developing the anaphylactic response to food allergens will be discussed. In addition, it has become apparent that there is a collaboration between these cells that contributes to an individual's susceptibility to IgE-mediated food allergy.

Effect of brine mineral water(BMW) on contact hypersensitivity reaction(CHR) was estimated using trimellitic anhydride (TMA) induced CHR in the mouse. BMW exhibited potent inhibitory activity on TMA induced CHR. BMW treatment suppressed the ear swelling, and attenuated hyper-activated lymph nodes stimulated by TMA challenge, thereby reduced their weight. The immunological index was analyzed after BMW administration in CHR. The level of serum IgE was significantly down regulated after BMW treatment. Furthermore, BMW showed inhibitory property of cytokine production. BMW treatment suppressed not only Th2 type cytokine, IL-4 but also pro-inflammatory cytokines such as TNF-${\alpha}$ and IL-6. From the histological analysis, the inflammatory context appeared by atopic dermatitis lesion after challenging with TMA are diminished by BMW treatment. Our results suggest that BMW may attenuate the development of CHR, and can be available for functional ingredient.

Drugs can have various adverse effects on the immune system including unintended immun-osuppression, induction of both drug-specific immune responses (including drug allergies) and non-specific immunostimulation (including autoimmune reactions), and direct activation of effector mechanisms (such as histamine release). As a practical matter, the Center for Drug Evaluation (CDER) relies on standard non-clinical toxicology studies to detect unintended immunosuppression. Specific assays using guinea pigs and mice are available to identify drugs that can induce immune-mediated dermal hypersensitivity reactions. Respiratory and systemic hypersensitivity and autoimmune reactions are more difficult to model in non-clinical studies. Unintended nonspecific immunstimulation can be detected in animal studies. CDER is currently developing specific guidance for evaluating potential drug immunotoxicity.

In the present study, we aimed to analyze the antinociceptive, immunomodulatory and antipyretic activities of nymphayol were investigated in wistar rats and mice. Antinociceptive effect was evaluated by acetic acid induced writhing, formalin induced paw licking and hot-plate tests. Immunomodulatory activity was assessed by neutrophil adhesion test, humoral response to sheep red blood cells, delayed-type hypersensitivity, phagocytic activity and cyclophosphamide induced myelosuppression. Antipyretic activity was evaluated by yeast induced hyperthermia in rats. Nymphayol produced significant (p<0.05) antinociceptive activity in acetic acid induced writhing response and late phase of the formalin induced paw licking response. Pre-treatment with nymphayol (50 mg/kg, oral) evoked a significant increase in neutrophil adhesion to nylon fibres. The augmentation of humoral immune response to sheep red blood cells by nymphayol (50 mg/kg) was evidenced by increase in antibody titres in rats. Oral administration of nymphayol (50 mg/kg) to rats potentiated the delayed-type hypersensitivity reaction induced by sheep red blood cells. Treatment with nymphayol showed a significant (p<0.05) reduction in pyrexia in rats. The results suggest that nymphayol possesses potent anti-nociceptive, immunomodulatory and antipyretic activities.
