In this study, the authors attempted to investigate distribution of the house dust mites in Korea on a nationwide scale. Mites were isolated and classified from 211 house dust samples which were collected from 7 urban areas and 3 rural areas. The result were as follows: 1) Nineteen species of mites were identified in this study including 4 new species which were not recorded in Korea. 2) The most frequent house dust mites were Pyroglyphid mites. Among then, Derntatophagoides farinae was found to be dominant species in Korea since this species was more widely distributed and more frequently found than D. pteronyssinus, 3) The occurence rates of Dermatophagoides sp. in the urban areas were higher than that in the rural areas, but vice versa in the occurence rates of other mites accidently found in the dust samples.

PURPOSE: The objective of this research is to provide the indoor environment management education program for the asthma patients and their families and then analyze the effectiveness in education preventing allergic asthma. METHODS: A pre-post single group quasi-experimental design was used to provide an education program about correct indoor environment management to a total of 58 households (29 patient households and 29 normal households). The performance rate of correct indoor environment management procedure, amount of house dust mite antigen, allergy subjective symptoms score and knowledge score about indoor environment management were compared before and after the education to test the effectiveness of the education. RESULTS: Home-visit education in this research had effects in improving subject households' performance rate of indoor environment management procedures, reducing the amount of house dust mite antigen - an important inducing factor of allergy, and reducing perceived subjective symptoms of allergy.

Studied group includes 42 patients with allergic rhinitis in whole the year by house dust mite. Control group includes 14 healthy, no allergic subjects. In normal person serum specific IgE level was nearly none. The most of allergic rhinitis patients had serum IgE with variois levels. The assay gave the same sensivity and specificity of 85.71%. In 6 patients non-consistent result of the assays was 14.29%. There is a correlation of these 2 assays with a coefficient of r = 6.12

This study was conducted to investigate distribution of the house dust mites in the bedroom of allergic rhinitis patients in Pusan. From July to December 1995, 51 dust samples were drawn from the bedroom of the patients by using electronic vaccum cleaner. House dust mites were isolated from 50mg dust by applying the modified wet sieving method. The results were as follows: 1 Out of a total 49 dust samples(96.1%) were isolated house mites. 2 Total 977 mites were collected and identified the most prevalent house mites was Pyroglypidae mite with 92.2%. Among them D.pteronyssinus was predominant species. 3 In 1gm of the house dust, 100-499 mites were found in 17 samples(33.3%), more then 500 mites in 12 samples (23.6%). 4 The density of Pyoglypidae mite was close associated with the month. 5 The density of house dust mite was not affected by the type of house, region and the relative humidity of the bed room

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.

It has been well known that prutic skin diseases are very common among the chicken raisers. Authors visited three paultry farming area in Kyung Ki Province to observe the avian mite dermatitis among the workers and to collect the causative paultry mites during the period from March to September, 1982. At every paultry farming area, we chose two families to investigate every family member and to check the dermatitis correlated with the mite that we had collected from the samples of each house dust and hen-house dust. The result were summarized as follows; 1. Ornithonyssus sylviarum (Canestrini and Fanzago, 1877) was found in dust samples from two houses and two hen-houses. And Dermatophagoides species and Acarus siro (Linnaeus, 1758) were also collected from the other house and henhouse samples. 2. Three cases of avian mite dermatitis were found in one family, where O. syiviarum was collected in the dust samples from their house and hen-house.
