[Relationship between bronchial asthma and mite].

We studied the relationship between bronchial asthma and mite as an antigen by reviewing previous reports. The incidence of the bronchial asthma has been increasing and it is estimated to be more than 2% of the total population. The main components of the antigen in the house dust (H, D.), which has been considered to be an important antigen of the perennial asthma, are Dermatophagoides farinae (D, f.) and Dermatophagoides pteronyssinus (D, p.) in H, D. The housing environment in recent years have become favorable for the reproduction of D, f. and D, p. It is considered that environmental pollution increases the incidence of asthma, especially infants.
