摘要
在花期前采集豚草植株的茎叶并制成过敏原浸出液,对44例豚草花粉皮试阳性及30例豚草花粉皮试阴性的秋季哮喘患者,作皮内试验和血嗜碱细胞组织胺释放试验(HRBT)。花粉皮试阳性组豚草茎叶浸出液皮试阳性率为88.6%(39/44),HRBT阳性率为70.5%(31/44)。而花粉皮试阴性组豚草茎叶浸出液皮试阳性率为13.5%(4/30),HRBT阳性率为6.6%(2/30)。20例健康对照其非花粉植株浸出液皮试均呈阴性反应。
Allergenic activities of ragweed leaves and stems collected before pollina- tion were studied.In 44 ragweed pollen-sensitive subjects with autumnal asthamtic attacks, intradermal test was positive in 88.6%(39/44)of the cases and HRBT(histamine-release- from-basophil test)was positive in 70.5% of the cases.In contrast,in 30 ragweed pollen in- sensitive subjects with seasonal asthmatic attacks,percentages of positive cases were 13.5% (4/30)and 6.6(2/30)respectively.Twenty non-atopic adult volunteers were negative.
