It is known that house dust mites which settle on sofa, carpet, and dust in the house ignite asthma and allergic rhinitis. Dermatophagoides farinae and Dermatophagoides pteronyssinus distribute widely and densely in Korea. In this study we carried out to identify that shed hair of dogs which was applied topically with fipronil ($\Frontline^{circledR}$) kill house dust mites. We co-cultured house dust mites with fipronil-applied hair of dog during 12 hours, and then compared the death rate of mites here with that cultured without hair. The larger amount of hair, the more mites were killed. The death rate of mites was higher than control significantly until 2 weeks after $\Frontline^{circledR}$ application. Hair which had been shed at 3 days after $\Frontline^{circledR}$ application always killed the smaller number of mites than not shed. The present study suggested that the use of $\Frontline^{circledR}$ to our pets control house dust mites effectively.

The purpose of this study were to identify seasons variation of house dust mites allergen and perceived allergic symptom. The subjects were consisted of 29 family with allergy patients and 34 family without allergy patients. Perceived allergic symptoms were accessed and house dust was sampled from beds, floor of bedroom, kitchen and livingroom in spring(August), summer (July), fall(October) and winter(January) and tested using two-site ELISA. The results were as follows; 1) In all family, amount of house dust mites allergen(Der fI) of livingroom floor was the highest in summer$(4.73{\mu}g/1g\;of\;dust)$, and then fall$4.67{\mu}g/1g\;of\;dust)$, winter$(3.94{\mu}g/1g\;of\;dust)$, spring$(1.73{\mu}g/1g\;of\;dust)$. 2) In family with allergy patients, amount of house dust mites allergen(Der fI) of bedroom floor was highest in fall $(9.75{\mu}g/1g\;of\;dust)$. 3) In family with allergy patients, amount of house dust mites allergen(Der fI) of mattress was highest in fall$(8.23{\mu}g/1g\;of\;dust)$. 4) Perceived allergic symptom scores of family with allergy patients were higher than family without allergy patients in all seasons. In family without allergy patients, perceived allergic symptom scores was the highest in spring(4.29) and perceived allergic symptom scores of family with patients was the highest in winter(2.49). 5) The relationship of house dust mites allergen and perceived allergic symptom scores were positively related (r=.941, p=.000). Perceived allergic symptoms were correlated with amount of house dust mites allergen, That is, perceived allergic symptoms were became worse by house dust mites allergen. So House dust mites allergen reducing strategies and intervention should be recommended in further study.

The exposure to house dust mites is closely connected with allergic diseases such as atopic dermatitis, allergic rhinitis and asthma. Control of house dust mite populations has been principally achieved by using chemical insecticides. But the risk to human health would be a potential problem. Moreover, house dust mite remain as allergens even after death. Therefore, repelling the house dust mites is more effective method than killing them. The use of plant-derived repellents has been considered as a promising alternative to chemical repellents. Eucalyptus oils are regarded as safe compounds, there have been attempts to commercialize and market the insecticides/repellent products containing Eucalyptus oil as such or based upon them. For that reason, we experimented repellent activity against these mites using laundry detergent with Eucalyptus oil in this experiment. House dust mites (Dermatophagoides farinae and Dermatophagoides pteronyssinus) were exposed at different concentrations (4, 8, 16, $32{\mu}L/mL$) in fabric treated laundry detergent with Eucalyptus oil for 24 hours. The repellent effects (%) of laundry detergent with Eucalyptus oil exposed at 4, 8, 16, and $32{\mu}L/mL$ were 48.16%, 74.62%, 52.67%, and 44.47%, respectively. These results suggest that laundry detergent with Eucalyptus oil have potential effect to repel the house dust mites.

Majority of asthma and atopic dermatitis are known to be spontaneously sensitive to house dust mite allergen. Control of house dust mite populations has been principally achieved by using chemical insecticides. But the risk to human health would be a potential problem. Moreover, house dust mite remain as allergens even after death. So, It is more effective method keeping the house dust mites away than killing them. The use of plant-derived repellents has been considered as a promising alternative to chemical repellents. Eucalyptus is a diverse genus of flowering trees in the myrtle family, Myrtaceae. It has insect repellent properties and is an active ingredient in some commercial mosquito repellents. These studies were carried out to investigate repellent effects of Eucalyptus oil against house dust mites and compare lemongrass oil. Eucalyptus oil and lemongrass oil were exposed at different doses (0.2, 0.1, 0.05, 0.025, 0.0125, $0.00625{\mu}l/cm^2$) and different times (1, 3, 6 hours) on house dust mites. The most effective dose of Eucalyptus and lemongrass oils against house dust mites was $0.1{\mu}l/cm^2$ and $0.025{\mu}l/cm^2$. Each repellent effect(%) in most effective dose was 90.3% (Eucalyptus) and 80.8% (lemongrass).

Purpose: The purpose of this study was to identify the indoor environment i.e. house type and age, ventilation method, use of bed & sofa, cockroach, ants, etc. on HDM (House dust mites), especially Der fI allergen. Method: Samples of dust from mattresses, pillows and the floor were collected by using a vacuum cleaner from April. 2000. The amount of Group I allergen(Der. fI) of HDM (house dust mites) were measured by two-site ELISA. Indoor Environmental characteristics were accessed by using questionnaires on 178 house wives living in the Seoul area. Results: The amount of HDM allergen (Der fI) was higher in sofa using house. There were higher concentrations of HDM allergen (Der fI) in sofas made from quilt material than for those that were made from leather. Homes that had pets like dogs living in them had higher concentrations of HDM allergen (Der fI) than without dogs. Conclusion: The photophobic mites thrive in dark. warm and humid environments; Items such as pillows. mattresses, box springs, blankets. carpets. and upholstered furniture should be considered ideal environments for the mite. Therefore, an indoor environmental control program should be carried out to avoid the HDM allergen.

House dust mites play an important role in the pathogenesis of allergic diseases. Many factors may influence mite growth. The presence of mites is related to mean temperature and humidity as well as altitude. The aim of this study was to analyze the mite fauna in 5 regions of western Anatolia, Turkey, that have similar climatic properties with low mean temperature and humidity, but differ in altitude. During the period October-November 2004, house dust was collected from 290 homes in 5 different cities. House dust mites were isolated in 67 (23.1 %) of 290 samples. The family Pyroglyphidae (Astigmata) was present in all positive samples. This study suggests that the selected western Anatolian regions that share similar environmental conditions host similar dust mite populations.

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.
