| individual allergens as risk factors for asthma and bronchial hyperresponsiveness in chinese children. | the role of allergen sensitization in the development of asthma in the chinese is not clear. this study aims to determine the relationship of sensitization to individual allergens, and the development of asthma and bronchial hyperresponsiveness (bhr) in schoolchildren from three chinese cities: hong kong, beijing and guangzhou. community-based random samples of 10-yr-old schoolchildren from three chinese cities were recruited for study using the international study of asthma and allergies in chi ... | 2002 | 11871366 |
| [individual allergens as risk factors for asthma and bronchial hyperresponsiveness in chinese children]. | objective this study aimed to determine the relationship between individual allergens with current wheezing and bronchial hyperresponsiveness (bhr) in schoolchildren from three chinese cities: beijing, guangzhou and hong kong. methods community-based random samples of 10-yr-old schoolchildren from the 3 cities were recruited for study using the international study of asthma and allergies in childhood (isaac) phase ii protocol. the subjects were studied by parental questionnaires (n = 10,902), sk ... | 2003 | 14746684 |
| detection of dermatophagoides farinae in the dust of air conditioning filters. | the allergenic dust mite species dermatophagoides pteronyssinus and dermatophagoides farinae generally inhabit warm moist environments. this study tested the hypothesis that these allergenic species may thrive in air conditioner filters. | 2007 | 17505140 |

| bioinformatic studies on the group 2 allergens of dermatophagoides farinae from china. | the present study aimed to characterize the group 2 allergens of the house dust mite dermatophagoides farinae (der f 2) from hainan island, a tropical region in southeastern china. we cloned and sequenced cdna coding for der f 2 and found an additional region of 87 base pairs (bp) (from +77 to +163 bp) in our strain that was absent in the reference sequence (genbank ab195580) used for primer design. however, the blast analysis identified the same sequence in strains reported from reinbek, german ... | 2007 | 18402292 |
| [mites in mattress dust and relevant environmental factors in student dormitories in shenzhen]. | three hundred and eight mattress dust samples were collected from college dormitories in shenzhen with a mite prevalence of 88% (271/308). from the samples, 6163 mites were isolated and identified. dermatophagoides farinae, d. pteronyssinus and blomia tropicalis were three most abundant species, occupying 29.7%, 21.7% and 17.9%, respectively. it was found that sex of the students, mattress cover (bamboo mat or bed sheet), with or without air conditioner installation, and daily using of air condi ... | 2009 | 19459513 |
| influence of environmental characteristics and climatic factors on mites in the dust of air-conditioner filters. | to investigate mites in the dust of air-conditioner filters (macf) in china, a total of 652 dust samples were collected from six cities: guangzhou (n = 129), nanchang (n = 127), shanghai (n = 113), xian (n = 93), beijing (n = 93), and shenyang (n = 79). tarsonemus granarius was the most dominant species (87.2%). dermatophagoides pteronyssinus and dermatophagoides farinae only represented 7.0 and 3.0% of total mites, respectively. with latitude increasing, both mite occurrence rate (p < 0.001) an ... | 2009 | 19840146 |
