Abstract
By using house dust antigens, in addition to the relation between specific Ig[immunoglobulin]E antobody, precipitin antibody and bronchial provocation test (BPT), the changes of serum complement [C] activities and eosinophil counts after BPT were studied. Decreased serum concentrations of C4 and factor B were found in 3 of 15 skin-test positive asthmatic children, thus confirming the involvement of C in the pathogenesis of immediate type BPT reaction. Eosinophil counts tended to increase after BPT but the increase did not correlate with the occurrence of the immediate type BPT reaction.
