[Clinico-immunologic characteristics of mite-borne bronchial asthma].

The authors describe clinicoimmunological features of bronchial asthma caused by Dermatophagoides pteronyssinus. This type of asthma usually afflicts young persons, its course is mild. The main symptoms are dyspnea, rhinitis and conjunctivitis.

[Immunochemical and acarological study of mites].

The data derived in the study of Dermatophagoides pteronyssinus by microscopic and immunological assays (double radial immunodiffusion in 2 modifications and indirect rat mast cell degranulation) are provided. The immunochemical assays permitting the detection of mites in 93.3% of cases have been shown to compare very favourably with the microscopic techniques that make it possible to detect mites only in 41.

[Comparative evaluation of the specific activity of different types of allergens from Dermatophagoides pteronyssinus mites].

The specific activity of different kinds of allergens prepared from dermatophagoid mites has been studied by the method of the indirect mast cell degranulation and the method of changing the volume of cerebral glial cells in patients with the atopic form of bronchial asthma. In cases of sensitization to mites the presence of reagin and precipitin antibodies has been revealed. Allergens prepared from the mite medium and directly from mites have been found to possess almost the same specific activity.
