  • The aim of this study was to observe the changes in allergenicity of saeujeot (salted and fermented shrimp) using a competitive indirect enzyme-linked immunosorbent assay (Ci-ELISA). The fermentation conditions tested for saeujeot consisted of various temperatures (25, 15, and $5^{\circ}C$) and salt concentrations (25, 15, and 10%). When saeujeot was fermented at a low salt concentration and high temperature, the binding ability of mAb and shrimp-allergic patient serum to allergen was significantly decreased. In particular, the binding ability of mAb to allergen in saeujeot fermented with 10% salt at $25^{\circ}C$ for 5 days decreased to 5%. Also, the binding ability of shrimp-allergic patient serum to allergen in saeujeot fermented for 5 days with 10% salt at $25^{\circ}C$ was 8%. In conclusion, the binding of mAb and shrimp-allergic patient serum to tropomyosin in saeujeot decreased with longer fermentation periods, lower salt concentrations (10%), and higher temperatures ($25^{\circ}C$).

  • We examined the responses of PBMCs to house dust mite (HDM) allergen in atopic and healthy, non-atopic dogs to identify differences in lymphocyte reactivity that might reflect the immunologic status of atopic dermatitis. Thirteen of 20 (65%) atopic dogs showed a positive lymphocyte proliferative response to HDM allergen. The rate of response was significantly higher in the atopic dogs than that in healthy, non-atopic dogs insensitive to the allergen (P = 0.007). The proliferative responses were positively correlated with the level of HDM-specific IgE in serum (P = 0.035), and were thereby confirmed to reflect the activity of lymphocytes competent to promote IgE production. These results suggest that HDM-specific lymphocytes were present in peripheral blood and played a role in the pathogenesis of canine atopic dermatitis.

  • Objectives: This study attempted to investigate the allergic histories and the distribution of offending allergens in the general public and further to help their diagnosis and treatment with Oriental Medicine. Methods: Allergic skin tests (AST) were performed and allergic histories were taken of 359 members of the general public who visited the International Exhibition on Oriental Medicine from Sept. 1 to Sept. 5, 2000. The allergen reagents for AST were three (House dust, D. farinae, Dog hair) and the control reagent was histamine solution. Results: 1.50.1 % of the subjects (n=359) were positive to AST. The ratio between males' positivity and females' was 1.06:1. 2. The younger the subjects were, the higher the positivity was. 3. The positive subjects' (n=180) positivity to three allergens was as follows: D. farinae 98.9%, House dust 30.0%, Dog hair 1.7%. 4. The younger the positive subjects were, the higher the positivity to House dust was. In contrast, the positivity to D. farinae was high in all age groups. 5.71.1 % of the positive subjects reacted positively to monotype allergen and 28.9% reacted positively to multiple allergens (2.46:1). The most common monotype allergen was D. farinae (98.4%) and the most common combination of multiple allergens was House dust and D. farinae (94.2%). 6.52.8% of the positive subjects (n=180) and 51.4% of the negative subjects (n=179) represented the history of allergic diseases. There was no relationship between allergic skin test and allergic diseases. Conclusion: To help in diagnosis and treatment with oriental medicine, research to analyze the relationship between allergic skin test and allergic diseases should be continued on the basis of Oriental medical theories.

  • The purpose of this study is to investigate the prevalent allergens causing canine atopic dermatitis in Daejeon area. Twenty two dogs were diagnosed with atopic dermatitis by an using intradermal skin test (IDST). Allergens used for the IDST included 33 allergen extracts from nine allergen groups: house dust mites (HDM), house dust, moulds, trees, weeds, grasses, insects/fleas, epithelia and others. The 22 purebred dogs with atopic dermatitis enrolled in this study included Shi-tzus (10/22, 45.5%), Yorkshire terriers (5/22, 22.7%), Miniature pinschers (4/22, 18.2%), Pugs (2/ 22, 9.1 %) and Cocker spaniels (1/22, 4.5%). The age of onset of atopic dermatitis ranged from 5 months to 5 years old (median: 1.79 years). The males (12/22, 54.5%) and females (10/22, 45.5%) were almost equal. The number of positive reactions to allergens recorded in each dog with atopic dermatitis was 3 (9/22, 40.9%), 2 (8/22, 36.4%), 1 (3/ 22, 13.6%) and 4 (2/22, 9.1 %), respectively. The most common positive allergen reaction was HDM (52.6%). The other positive allergen reactions recorded were from house dust (17.5%), insects/fleas (15.8%), trees (5.3%), moulds (3.5%), kapok (3.5%), silk (3.5%), epithelia (1.8%), weeds (0%) and grasses (0%), respectively. Positive reactions recorded to Dermatophagoides farinae and D. pteronyssinus were in 53.3% and 46.7%, respectively. The IDST results demonstrate that the most common causative allergens in canine atopic dermatitis in Daejeon area were HDM.

  • Malignant melanoma is rare in Asians and one of the poorer prognostic diseases. Malignant melanoma accounts for only a small ratio of all skin cancers, but it causes the greatest number of skin cancer - related deaths worldwide. Melanoma incidence has continued to increase worldwide and in Korea, like other countries, the number of patients has increased compared with previous cancer incidence data. In this case report, we describe a case of a malignant melanoma patient who showed neck node metastasis (right supraclavicular area) after wide excision of facial melanoma 2 years before the diagnosis of relapse. The patient refused to get conventional western medical treatment including chemotherapy and the size of cancer increased over the 5 months of clinical follow-up. After 4 months of traditional Korean medical treatment using allergen-removed Rhus verniciflua Stokes(A-RVS), however, the size of cancer mass decreased and the patient showed no side effects. Further study will be needed in order to determine the long-term effect of allergen-removed Rhus verniciflua Stokes on patients with malignant melanoma.

  • The purpose of this research is to investigate and analyze food allergy labelling for the arrangement of improvement plans. Survey was done as a quantitative research targeting food industry employees with 399 random workers in Seoul and Gyonggi area. The data was analyzed using SPSS windows (ver. 12.0) for frequency analysis, t-test and factor analysis. The importance and performance of the food allergen labelling were divided by 15 items. Only 43.1% of the workers understood the operation allergic food labels. The first improvement on allergic food labels was "using boldface for food allergen labes". The importance of all of these factors was significantly higher than performance. The selection attributes with relatively low the performance but high importance(2 quadrant) were "consumer education for allergic food labels" and "training of professional counselors on food allergy". Therefore, the factors to be improved through the IPA were consumer education and training of professional counselors. With this research and extended efforts for revision of laws, reliability of food industry and accuracy of food labelling would improve, thereby boosting the productive commercial activities in labelling code.

  • Objectives: The main purpose of this study is to produce background data which can be compared with several large-scale industrial complex regions. Methods: The framework of this study was designed to evaluate and monitor health effects associated with low-level and long-term exposure to environmental pollutants. In this study, 1,009 local residents were recruited in the city of Chungju using personal questionnaires, medical check-ups, and allergen skin-prick tests for 12 common allergens. The prevalence rate of skin allergens was reviewed together with that from large-scale industrial areas. Results: The diagnosis prevalence and medical treatment prevalence of asthma was 5.6% and 1.7%, respectively. Allergic rhinitis was 25.4% and 16.7%, allergic dermatitis was 16.6% and 9.9% and allergic conjunctivitis was 18.7% and 7.9%, respectively. These results were similar with those of industrial complexes. The prevalence of allergen skin-prick test was 16.4% and the most common allergen was dust mites (27.9-31.6%). This result was lower than those of the industrial complexes (22.5-39.9%) and Gangneung (18.2-24.7%). Conclusion: Further study is required to find the cause of the regional differences in skin prick prevalence.
