최근 들어 알레르기 질환이 급증하고 있다. 국내 알레르기 환자 수는 6백만 명 이상이며 서구화된 생활환경, 공해, 각종 화학물질 사용의 증가로 인해 환자는 계속 증가 추세이다. 현재 추정되는 환자수 만도 전 인구의 15~20%선, 우리 나라 성인 중 약 10%, 어린이는 약 20%에서 나타나고 있는 것으로 알려져 있다. 대표적인 알레르기 질환은 꽃가루에 의한 화분증과 집먼지 진드기, 동물의 털 등이 주원인인 알레르기성 비염.결막염.천식.피부염 등이 있다. 그러나 알레르기 질환은 주위에서 흔히 접하면서도 일반인들에게 막연히 알려져 있고, 단지 완치가 힘들어 난치병 정도로만 인식되어 있다. 알레르기 질환 보통 대부분의 사람에게 있어서는 아무런 문제도 일으키지 않는 물질이 어떤 사람에게만 두드러기, 비염, 천식 등 이상과민반응을 일으키는 것을 말한다. 알레르기도 우리 몸 속에서 일어나는 면역반응의 한 종류지만 몸에 유해한 반응을 말하며 요즘 들어서는 과민성이란 의미로 사용된다.

Dermatophagoides pteronissinus (DP) is one of the house dust mites (HDM) associated with allergic diseases. The cysteine protease Der p 1 from DP is a powerful allergen. The pathogenic mechanism of allergy is involved in cytokine secretion of lymphocytes and spontaneous apoptosis of neutrophils. In this study, we investigated whether Der p 1 induces cytokine secretion of lymphocytes and if the release of cytokines is associated with regulation of neutrophil apoptosis. In normal and allergic subjects, Der p 1 increased IL-6, IL-8, MCP-1, and GM-CSF release in a time-dependent course. Supernatants collected from normal and allergic neutrophils after Der p 1 stimulation suppressed the apoptosis of normal and allergic neutrophils, although Der p 1 alone has no effect on neutrophils. Der p 1 suppressed neutrophil apoptosis in coculture of normal neutrophils with normal lymphocytes. Der p 1 more strongly suppressed apoptosis of allergic neutrophils cocultured with allergic lymphocytes than normal neutrophils cocultured with normal lymphocytes. In summary, Der p 1 increases the secretion of cytokines, which has anti-apoptotic effects on neutrophils of normal and allergic subjects. These results will contribute to elucidate the pathogenic mechanism of allergic diseases.

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.

Purpose: The purpose of this study was to investigate the effect of the asthma management educational program given to the allergic asthmatics receiving immunotherapy due to house dust mite on the disease related to knowledge, stress, and self-efficacy. Method: The subjects of this study were the patients received immunotherapy to house dust mite at a week interval after being diagnosed for house dust mite allergic asthma at the respiratory center of a hospital affiliated to the university. They were divided into the experimental group of 29 patients who received asthma management education, the control group of 32 patients, and 61 patients in total. Experimental treatment, as an asthma management educational program, was the group education of one time and the reinforcement education of three times with environmental therapy and immunotherapy to house dust mite. Results: The results revealed that the improvement in disease related knowledge, the improvement in self-efficacy and the decrease in stress, were significantly higher in the experimental group than the control group. Conclusions: The asthma management educational program had an effect on improving the disease related knowledge and self-efficacy, and decreasing the stress of the patients asthmatics allergic to house dust mite.

This study was conducted to provide basic knowledge of effective environmental control of patients with allergic rhinitis during the period of July to December 1995. The subjects were consisted of 29 patients with allergic rhinitis. Each patient of nasal symptom scores assessed and dust samples drowned from their bedrooms twice for 1 month interval. The data. 58 samples were analyzed by using ANOVA. t-test and stepwise multiple regression. The results were as follows 1. Out of a total 52 dust samples $(89.7\%)$ were isolated house mites. Total 815mites/0.5gm dust were collected and identified the most prevalent house mites was Pyroglypidae mite with $81.1\%$ 2. The amount of house dust mites in the group of bedding laundry with hot water was significantly lower than that those of with cold water. 3. The nasal symptoms of the patients in the group of bedding laundry with hot water was significantly less than that those of with cold water. and also those of using large size bedroom was significantly lower than that those of using small size one. The nasal symptoms of the patients was closely associated with the washing water temperature. bedroom size. bedroom temperature. type of bedclothes, and frequency of cleanig room.

House dust mite was the most important cause of allergic asthma and rhinitis. More than 70% of Korean children and about 50% of adult with respiratory allergy were sensitive to house dust mite. This experiment was indoor environment in house and house dust mite existence inquiry. From 23rd December 2005 to 28th February 2006, dust samples were collected from the bedclothes by a vacuum cleaner and air sampler And the levels of Der f1 and Der p1 were determined by ELISA((Enzyme-Linked Immunosorbent Assay). The results were as follows : 1 The dust mites allergy contaminations of bedclothes in house were higher than international standards(2000 ng/g). 2. In type of dust mite, the Korean house the almost have the D. farinae other than D. pteronyeeinus of mite. 3. The Der f1 and Der p1 levels per gram of dust from the bedclothes were 2074.99 ng on average, but they did not exist in air. The concentrations of house dust mite were significantly high in the bedclothes. This results suggest that the bedclothes have enough concentrations of dust mites to develop the sensitization. The control of indoor environment should be emphasized to prevent the sensitization by the repeated exposure to dust mite.

This study was conducted to provide basic knowledges of effective environmental control of patients with allergic rhinitis. From July to October 1995, 58 dust samples Were drawn from the bedrooms of patients with allergic rhinitis who were registerd at an allergy clinic of a hospital. Those samples were examined for the amount of house mite allergens & dusts. The data were analysed by using ANOVA and Pearson correiation coefficients. The results were as follows : 1. As for the amount of house mite allergens in terms of environmental factors, the amount of house mite allergens of using washing water temperature of bedding above than $55^{\circ}C$ was significantly lower than that of below $54^{\circ}C$. Other environmental factors such as type of house, area of bed room floor, bed in bedroom, bedroom cleaning by vacuum cleaner, days after bedding washing, relative humidity of bedroom were relate to the amount of house mite allergens. 2. As for the amount of dusts in terms of environmental factors, the amount of dusts of days of days after bedding washing more than 15 days was significantly lower than thant of less than 15days. Other environmental factors such as type of house, area of bedroom floor, bed in bedroom, bedroom cleaning by vacuum cleaner, was hing water taemperature of bedding, relative humidity of bedroom were not relate to the amount of dusts. 3. There was a significant positive correlation between the amount of house mite allergens and the amount of dusts. It may be conclusively said. the amount of dusts and house mite allergens were closely associated with the washing temperature and days after washing of bedding. Hence. intensive instruction for the methods of bedding washing was needs of the patients with allergic rhinitis.

Canine sarcoptic mite (Sarcoptes scabiei var. canis) is ectoparasite which burrow usually in the stratum corneum of the skin of dogs. Antigens from the burrowing mites induce humoral and cellmediated immune responses in the hosts. The effect of antigenecity induced by somatic antigens of house dust mite (Dermatophagoides pteronyssinus) isolated by continuous elution has been evaluated in canine sarcoptic mites infestation. Continuous elution was carried out in 7.5% SDS-PAGE to isolate proteins of common antigens from somatic antigens of house dust mite. These eluted proteins from somatic antigens of house dust mite were confirmed by Western blotting in 7.5% SDS-PAGE, and eluted proteins (65, 60 kDa) were isolated. To evaluate the antigenetic effect of eluted proteins, eight dogs were divided as 4 groups such as non-vaccinated and non-challenged control (Group I), challenged control (Group II), vaccinated (Group III), and vaccinatedandchallenged (Group IV) groups. Group II and IV were artificially infested canine sarcoptic mites. Group III and IV were immunized with eluted proteins (65, 60 kDa). At the 6th week of the vaccination, the antibody titers of Group of IV were statistically significant higher than those of Group II (p<0.05). And antibody titers of Group III were also statistically significant higher than those of Group I (p<0.05). From these result, it is possible to replace somatic antigens of canine sarcoptic mites with eluted proteins from somatic antigens of house dust mites in order to diagnose and prevent the canine sarcoptic mite infestations.

To find out the effectiveness of clinical examination for detection of dermatophagoides farinae allergen asthma disease, 50 patients (control group) and 50 healthy persons matched by sex and age to the control group, were tested for allergen asthma. The results of the study follow. The ESR there was significantly different from the comparisons of the patients' normal reference values, 95.3 % in ESR, patient groups allergen asthma and heamatology values with control group. The ESR level of allergen asthma patients, $62.23{\pm}35.09$ mm/hr, was higher than that of the controls, $9.47{\pm}5.36$ mm/hr (p<0.001). The eosinophil count level of the patients, $370.65{\pm}365.45mm^3$, was higher than that of the controls with $171.99{\pm}131.80mm^3$ (p<0.001). The IgE level of the patients, $1137.79{\pm}784.69IU/ml$, was higher than that of the controls with $71.29{\pm}14.28 IU/ml$ (p<0.001).
