Among the inhalant and foods which caused allergy, which is increasing nowaday, this research has a purpose of studying allergy-causing materials (allergen) which most frequently cause allergy. In order to conduct this research, we selected 100 hundred patients (M : F = 65 : 35) from in Kwangju Christian Hospital, who were tested through allergy multiple antigen simultaneous test (MAST) immunoblot assay (RIDA$^{(R)}$ X-Screen; r-Biopharm Co., Darmstadt, Germany). According to the test, the total IgE positive rate (above Class 2) from the inhalant is 58.3%, and that from food is 35%, respectively. This research showed that the first most allergen was the tick (Derm. farinae/Derm. pteronyssinus), the second most was housedust, and the third was the hair of pets such as cats and dogs; 65%, 35%, 26.3% in inhalant panel, and 52.5%, 40%, 50% in food panel, respectively. Thease allergens newly added to inhalant and food panels were not contributable to the detection of specifical allergen. We needs further improvement to be used as primary screening or quantitative test for allergy.

Objectives The purpose of this study was to explore the differences in allergic reactions by type of Sasang constitution using multiple allergen simultaneous test(MAST). Methods This study was conducted using the big data of Korean medical health checkups. Subjects with a history of allergic disease, Sasang constitution type information, and MAST results were included. Subjects who had taken drugs before MAST that affected allergic reactions were excluded. We compared total immunoglobulin E(IgE) concentrations, and the number of positive antigens by Sasang constitution using analysis of variance. The presence or absence of a positive reaction and specific IgE concentration classes of 92 antigens in MAST were analyzed by Fisher's exact test or Chi-squared test. Results The distribution of Sasang constitutional types of Tae-Yang, Tae-Eum, So-Yang, and So-Eum among 147 subjects was 2.7%, 42.9%, 38.1%, and 16.3%, respectively. There was no statistically significant difference in the total IgE concentration, the number of positive antigens, and specific IgE concentration classes for each antigen. There was a statistically significant difference in MAST-positive reaction for alder and pine antigens by type of Sasang constitution, and Tae-Eum had the most. Conclusions Tae-Eum showed a relatively strong positive reaction to a large number of antigens compared to the other types, but no statistically significant difference was observed. It is necessary to continuously investigate allergic reactions to provide evidence for the treatment of allergic diseases by Sasang constitution.

As the allergic diseases in patients are increasing, it is important to find out the allergens. A multiple antigen simultaneous test(MAST) is a simple method for in vitro measurement of allergen-specific IgE antibodies. This study was performed to evaluate the relationship between allergen-specific IgE antibodies, serum total IgE and peripheral eosinophil count in the allergic patients. According to the results of the study, the total IgE positive rate(above class 2) from the inhalent is 96.97%, and that from food panel is 98.06%. The research showed that the positive rate of the allergen-specific IgE was House dust 51.52%, D. farinae 45.46%, Cat 31.99% in inhalent panel, and 55.34%, 42.72%, 34.96% in food panel. Serum total IgE was associated with allergy, however, allergy was not always associated with eosinophilia.
