| the house-dust mite and childhood asthma in the cape peninsula. | sensitivity to house-dust and the mites dermatophagoides pteronyssinus and d. farinae was the commonest cause of asthma in children living in the cape peninsula. of 103 asthmatic children examined, 65,5% had positive skin tests to these allergens. only a small number of the children were sensitive to pollens, feathers, moulds or food. the median serum ige level was 496 u/ml, with a range of 18-15972 u/ml, and the median blood eosinophil count was 691/microliter (range 93-8 159) in 102 of the chi ... | 1977 | 897857 |
| controlled trial of hyposensitisation to dermatophagoides pteronyssinus in children with asthma. | hyposensitisation with dermatophagoides pteronyssinus tyrosine absorbate in asthmatic children with bronchial sensitivity to d. pteronyssinus was effective in a 12-month double-blind controlled clinical trial. compared with controls, treated children used a smaller quantity of drugs while maintaining clinical and lung function improvements. in most children who improved there was no change in immediate response to d. pteronyssinus on bronchial provocation test, but the late reaction was lost in ... | 1978 | 81927 |
| measurement of igg, iga and ige antibodies to dermatophagoides pteronyssinus by antigen-binding assay, using a partially purified fraction of mite extract (f4p1). | an extract of dermatophagoides pteronyssinus culture has been fractionated by chromatography on sephadex g-100 and pevikon block electrophoresis to obtain a partially purified allergen (f4p1). this preparation has a molecular weight of between 15--25,000 dalton, migrates slowly on electrophoresis, and is colourless in solution. the skin-test reactivity of f1p1 was comparable to that of crude d. pteronyssinus extract. f4p1 was radio-labelled with 125i and used in an antigen-binding radioimmunoass ... | 1978 | 750116 |
| house dust mite sensitivity in childhood asthma. | the clinical features of perennial asthmatic children with a skin or bronchial reaction to the house dust mite (dermatophagoides pteronyssinus) were compared with those of asthmatic children without mite sensitivity. mite sensitive asthma was characterised by an early age of onset of symptoms, these being predominantly nocturnal. a history of wheezing precipitated by dust exposure, during vacuuming, bedmaking, or dusting was present in 52% of cases. asthmatic children with mite sensitivity were ... | 1978 | 718239 |
