OBJECTIVE: In order to study the relationship between @entity2023 and airway hyperresponsiveness. METHOD: Each of them were separately engaged skin test with antigen. All 50 @entity1 had intense positive reaction to artemisia pollen (++-+++), but all controls were negative. We conducted bronchial provocation test (BPT) with 1:100 (w/v) artemisia pollen. Before and after BPT, we separately tested the forced expiratory volume in first second (FEV1) which represented ventilative function and eosinophil cationic protein (ECP) in their serum. RESULT: Before BPT, 50 @entity1 and 20 normal controls had no @entity825 symptoms. FEV1 of 50 @entity1 is (70 +/- 20)%, that normal controls is (85.6 +/- 8.9)% (P < 0.001). After BPT, in 50 @entity1 , 23 cases felt constriction in the chest, 10 cases had wheezes, 5 cases had @entity565 , 12 cases had no symptoms. At the same time, all of normal controls had no symptoms. After BPT, FEV1 of 50 @entity1 is (60 +/- 20)%, that of normal controls was (85.6 +/- 8.9)% (P < 0.05), ECP of @entity1 was (30.37 +/- 18.92) micrograms/L, that of controls was (5.245 +/- 3.228) micrograms/L (P < 0.05). CONCLUSION: @entity1 with @entity2023 not only have chronic @entity32 in their nose mucosa that results from allergic react, but also have chronic @entity32 in bronchus which leads to @entity5874 . The results reveal that most @entity1 with @entity2023 have @entity5874 (76%).
