Objective To explore the sensitizing effect of platanus acerofolia pollen on patients with extrinsic asthma. Methods The skin prick test (SPT) and bronchial provocation test (BPT) were carried out with platanus acerofolia pollen extact (PAE) in 46 patients with extrinsic asthma and the changes of serum lgE levels were detected by BA-ELISA method. Results The SPT showed that 24 cases were strong positive, 22 cases were negative. The PEV1 and PEF of the group with positive SPT to PAE after inspiring PAE were significantly lower than those in basis and after inspiring NS and those of with negative SPT to PAE (t=2. 414-7. 569, P0. 001,0. 05); In the group with positive SPT. 17 cases were positive to BPT. No cases were positive to BPT in the group with negative SPT. There was no significant difference of serum IgE levels between the groups with positive and negative SPT to PAE (t= 1. 558, P0. 05). Conclusion PAE is one of the important allergens to patients with extrinsic asthma. [
