The aim of this study was to examine and compare the eating habits, dietary intake patterns and nutrient intake status of children with and without atopic dermatitis by questionnaire during July, 2008. A total 388 subjects of 5th and 6th grade elementary school children (AG: atopic group, n=65, NG: non-atopic group, n=323) in Seoul and Ulsan areas participated in this study. The questionnaire included general characteristics, dietary habits, and atopy-related food frequency. One-day 24 hour recall was collected to estimate nutrient intakes of the subjects. The data were analyzed by Chi-square test for food frequency analysis and by t-test for nutrient intakes. Atopy-related foods included milk, buckwheat, beef, pork, chicken, crab, egg, mackerel, peach, and tomato. From the findings, AG had a more irregular eating habit than NG (p<0.05). In case of food frequency, AG tended to consume more atopy-related foods than NG (p>0.05). The nutrient intakes of AG were significantly lower than those of NG (p<0.05), but only intake of animal iron in AG was higher than NG (p<0.05). NG consumed more protein than AG (p<0.05). Although milk was a noted hypersensitive allergic food, frequency and the amount of milk intake were not significantly different between two groups. In conclusion, atopic children had eaten more atopy-related foods and less nutrient intakes. Therefore, it is necessary to educate on good nutrition and guide atopic children and their parents.

Purpose: Eosinophilic colitis is a disease characterized by gastrointestinal symptoms, peripheral eosinophilia, eosinophilic infiltration of the colonic wall. The etiology and pathogenesis of this disease is not clear and it is considered to be idiopathic. This study aimed to ascertain the clinical features, treatment and prognosis of eosinophilic colitis in early infancy. Methods: We reviewed 6 infants retrospectively, presented with bloody stool in early infancy, who were diagnosed with eosinophilic colitis in Pusan National University Hospital between August 2002 and February 2004. Results: Five males and one female were included. The mean age when bloody stool was identified was $79.2{\pm}56.1$ days (10~145 days). All but one infant with atopic dermatitis did not have other allergic diseases. Nobody had a family history of allergic disease. No specific dietary history in infants and their mothers related to food allergy was identified. Peripheral eosinophilia (total WBC count $11,763{\pm}3,498/mm^3$, eosinophils $17.0{\pm}4.3%$, absolute eosinophil count $2,044{\pm}996/mm^3$) was observed in all infants. Colonoscopy in six infants revealed diffuse erythema, congestion and granulation pattern of mucosa in the rectosigmoid colon. Histopathologic findings of colononic biopsies showed chronic inflammation with severe eosinophilic infiltration in the mucosa. Two infants were treated with hydrolyzed casein-based formula and four infants with prednisolone. Gastrointestinal symptoms and peripheral eosinophilia resolved completely with prednisolone and partially with a hydrolyzed casein-based formula. Relapse was not observed during the follow-up period. Conclusion: Our study demonstrated that there is no evidence of a definite relationship between eosinophilic colitis and food-allergic disorders. Clinical course and prognosis of infantile form of eosinophilic colitis is very favorable and treatment with prednisone was effective.

Abdominal skin tissues of ICR mouse painted with Dinitrochlorobenzene (DNCB) were observed to investigate the delayed type hypersensitivity of skin by chemical allergen as hapten. The abdominal skin tissues were obtained at hour 48 after secondary DNCB sensitization that were stained by Luna's method for mast cell, and immunohistochemical stain method for IL-2 receptor. The superficial perivascular lymphocytic aggregation were shown in basement membrane after DNCB secondary painting and the large size capillaries in dermis were appeared. The infiltration of lymphocyte to epithelium, the vacuolation of epithelial cell and intercellular space were increased. The number of mast cell in dermis was increased and these shape is degranulation type. The number of IL-2 receptor positive cell was increased in dermis. As results indicated that the hypersensitivy of immune system were induced by DNCB, subsequently to damage evoke inflammation in skin.

This study compared the individual, family, environmental factors, and subjective sleep sufficiency according to gender among Korean adolescents and to examine relevance among the individual, family, environmental factors, and subjective sleep sufficiency. The subjects were 65,528 Korean adolescents(male: 33,803, female: 31,725), who were derived from the 12th Korea Youth Risk Behavior Web-based Survey 2016 in South Korea. As a result, the prevalence of the subjective sleep sufficiency in this study was 33.4% male and 19.5% female. The subjective sleep sufficiency was affected by the depression experience, suicidal ideation, school achievement, feeling of stress, feeling of happiness, subjective health status, alcohol experience, smoking experience, substance experience, allergic rhinitis, and atopic dermatitis in individual factors; economic status, educational level of parents and living arrangement in family factors; school grade, school type and emotional support in environmental factors in both males and females. In individual factors, breakfast eating and asthma affected the male's subjective sleep sufficiency and physical activity affected the female's. The mental health of the individual factors was the most influential factor in adolescent's subjective sleep sufficiency. Therefore, nursing intervention to improve Korean adolescent's subjective sleep sufficiency should be applied considering gender differences.

Epinastine is an antiallergic drug effective for bronchial asthma, allergic rhinitis, urticaria and dermatitis. Epinastine is topically active, direct H1-receptor antagonist and an inhibitor of the release of histamine from the mast cell. The purpose of the present study was to evaluate the bioequivalence of two epinastine hydrochloride tablets, Alesion Tablet (Boehringer Ingelheim Korea Ltd.) and S-napine tablet 10 mg(Sam Chun Dang Pharm. Co., Ltd), according to the guidelines of the Korea Food and Drug Administration(KFDA). The release of epinastine from the two epinastine formulations in vitro was tested using KP VIII Apparatus II method with various dissolution media(pH 1.2, 4.0, 6.8 buffer solution and water). Twenty six healthy male subjects, $23.35{\pm}1.57$ years in age and $66.29{\pm}10.61kg$ in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After two tablets containing 20 mg as epinastine hydrochloride was orally administered, blood was taken at predetermined time intervals and the concentrations of epinastine in serum were determined using HPLC with UV detector. The dissolution profiles of two formulations were similar at all dissolution media. In addition, the pharmacokinetic parameters such as $AUC_t,\;C_{max}\;and\;T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t.\;C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, Alesion tablet, were 1.50, 1.46 and -13.48% for $AUC_t,\;C_{max}\;and\;T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25(e.g., log 0.95$\sim$log 1.12 and log 0.93$\sim$log 1.10 for $AUC_t\;and\;C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating S-napine tablet 10 mg was bioequivalent to Alesion tablet.

Purpose: Recently, complementary and alternative medicine (CAM) has been increasingly used in children. Studies have shown that 34% of adults and 11% of children use CAM in the USA and Canada. The purpose of this study was to investigate the prevalence and patterns of CAM use in elementary children in Korea. Methods:From July to August 2007, parents of elementary children completed a questionnaire survey at Gwang-ju. In all, 794 questionnaires were analyzed. Results:Of the 794 respondents, 278 answered that their pupils (35%) had experienced CAM. The following types of CAM therapy were used: herbal medicine, 62.5% dietary supplements, 31.2% vitamins, 30.2% and acupuncture, 11.1%. CAM therapies were used for the following diseases: nutritional deficiency, 33.3% atopic dermatitis, 31.3% arthralgia, 31.3% allergic rhinitis, 28.8% obesity, 26.3% and asthma. The following were the motives to use CAM: prevention of diseases (33.5%), dissatisfaction with modern medicine (21.2%), and complementary therapy to modern medicine (20.5%). People gained information about CAM through neighbors (65%) and mass media (21%). Moreover, 83 parents (30%) were satisfied with CAM because of its effectiveness. Conclusion:Many parents have advocated the use of CAM in their children. However, most of them used CAM without any prescription or adequate knowledge. Further studies are required to determine the efficacy of CAM.

Allergic contact dermatitis is a common skin disease resulting from specific immumologic sensitization to topically applied various allergen. Purpose of this study was to investigate skin morphologic chganges by light microscopic, changes of protein band by SDS-PAGE in the skin treated on the surfactant. Furthermore, lectin histochemistry is used to know the chagnges of the terminal sugar of the glycoconjugate in the skin treated on the surfactant. The results were as follows : The 1 day of treated group was indicated the enlargement of capillary, the 3 days of treated group was showed that the cytoplasm was eosinophlic by the pyknotic of nucleus. The 6 days of treated group was observed hyperkeratinoid, increased of inflammation cells to epithelium. The 9 days of treated group was appeares that serum crust was sheded and formed a acanthosis. But dermis layer was cytoplasmic vaculation and enlargement of intercellular space. The 12 days treated group made up new epidermis layer of seven layer and of observed an decreased in quantity of inflammation cells. The mast cell of degranulated type was increased in treated surfactnat. It was secreating granules hold histamin, serotonin and heparin. Accordingly, protein band of electrophortic phase was observed a sudden changes since 3 days treated group. At observeation of the cell-surface glycoconjugates, LCA, PNA, SBA and WGA lectin positive cells but inducated lectin negative cells in Con-A. Furthermore, PNA and SBA showed stroger positive reaction as treated surfactant group.

Purpose: The aim of the present study was to investigate the clinical features and outcome of eosinophilic gastroenteritis (EGE) in children. Methods: Our study enrolled 24 children who were diagnosed with EGE from 1993 to 2014 at the Department of Pediatrics, Seoul National University Children's Hospital. The patients' clinical manifestations, treatments, and outcomes were reviewed from the medical records. Results: The mean age at diagnosis was 5.3 years. Most patients had gastrointestinal symptoms including diarrhea (54.2%) and abdominal pain (45.8%). Peripheral eosinophilia was present in 91.7% of the patients. Thirteen patients (54.2%) showed anemia, and 15 patients (62.5%) had hypoalbuminemia. EGE was classified as mucosal, subserosal, or muscular in 75.0%, 20.8%, and 4.2% of cases, respectively. Three patients showed gastroduodenal ulcers upon endoscopic analysis. A history of allergy was reported in 13 patients, including atopic dermatitis, allergic rhinitis, and asthma. Five patients (20.8%) improved with food restrictions. Among the 19 patients treated with steroids, 11 (57.9%) discontinued steroid treatment without subsequent relapse, 4 (21.1%) relapsed after ceasing steroid treatment, and 4 (21.1%) showed no response to steroids. Two patients who were resistant to steroids underwent therapeutic surgery. The presence of gastroduodenal ulcers was significantly associated with relapse and steroid resistance. Conclusion: A high suspicion of EGE is warranted when children have nonspecific gastrointestinal symptoms and peripheral eosinophilia. Most patients improved with food restrictions or steroid treatment, although one-third of patients showed a relapse or steroid resistance.

A three-year-old male jindo with generalized skin lesions (including seborrhea, hyperk- eratosis, alopecia, papules, and ecchymoses), pruritus lymph node enlargement, and fever was brought to Veterinary Teaching Hospital, College of Veterinary Medicine, Chungbuk National Uni- versity. There were no laboratory findings for parasites and fungi in the hair and skin But, the com- plete blood counts (CBC) showed leukocytosis and severe cosinophilia, It was suspected to be an inflammatory and allergic dermatitis. Thus, prednisoIone (0.5 mg/kg PO, BID for 1 week) and ampi- cillin (10 mg/kg PO, BID for 1 week given. One week later, pruritus and ecchymoses were reduced. These treatments were repeated for 7 day again. Three months later, the dog was presented again due to the relapse and exacerbation of the clinical signs. The signs were as follows; severe pru- ritus, vesicobullous skin lesions, anorexia, emaciation, lameness, and welling of carpal joints that showed inflammatory skin lesion and draining of synovia-like fluid. The values of WBC counts were returned to normal ranges. In contrast, eosinophilia was still observed. Coombs test for patient RBC and serum were negative. Hypoalbuminemia (2.5g/dl) was shown by serum chemistry. The uri- nalysis revealed and presence of leukocytes. Luxation finding of right radial carpal joint by polyarthritis was shown in radiography of affected joints.Lupus eryhematosus(LE) cells also appeared in peripheral blood and synovial fluid of affected joints. Definitely, antinuclear antibody (ANA) of patient serum using feline peripheral blood mononuclear cells was detected by all immu- nofluorescence. Based on these findings such as sedum ANA-Positive. major signs (skin disease, non- erosive polyarthritis with soft tissue swelling. and proteinuria), minor signs (fever), and LE cell-pos- itive, a diagnosis of systemic lupus crythematosus (SLE) was mad\ulcorner in this dog. The dog with SLE was administered with Pre(2.0 mg/kg PO, BID for first 4 week and then QOD) to inhibit the production of autoantibodies and with ampicillin (10 mg/kg PO, BID for first 4 weeks and then QOD) to prevent the secondary infection. The condition of this dog was monitored every 2 weeks by physical examinations, radiography, CBC, serum chemistry and urinalyais. At 8th week of treat- ment, the state of SLE evaluated by physical examinations and laboratory findings was markedly improved except for proteinura.
