目的了解呼和浩特市气传花粉的种类、数量、飘散规律,探讨其与花粉症的关系。方法 2008年6月1日—2009年5月31日采用Durham重量玻片法取样进行气传花粉的调查,并对612例花粉症患者进行变应原皮肤试验及发病季节调查,分析其与花粉浓度间的相关性。调查结果与1984—1985年度进行分析比较。结果全年观察到花粉种类56种,收集花粉17 680粒。气传花粉飘散高峰集中在春季的3—5月和秋季的7—9月。花粉症患者的发病季节与气传致敏花粉高峰期相吻合,2次调查相比,花粉种类、数量均成倍增长,秋季花粉所占比率稍减少,春季花粉数量明显增加。蒿属花粉为优势气传花粉。结论该调查为呼和浩特市气传花粉的流行病学研究提供了参考资料,对该地区与花粉相关的变应性疾病的防治具有一定的临床指导意义。
Objective To understand the species, quantity and dispersion of airborne pollen in Hohhot and to explore its relationship with hay fever. Methods From June 1, 2008 to May 31, 2009, the Durham weight slide method was used to sample the airborne pollen and the allergen skin test and season investigation were performed in 612 cases of pollinosis. Correlation between concentrations. The survey results are compared with those of 1984-1985. Results A total of 56 pollen species were observed and 17 680 pollen collected. Gone with the Wind Gone with the Peaks are concentrated in March-May in the spring and July-September in the fall. The onset season of hay fever patients was coincident with the peak of air-pollination sensitized pollen. Compared with the two surveys, the pollen types and numbers doubled. The percentage of autumn pollen decreased slightly and the quantity of pollen in spring increased significantly. Artemisia pollen is the dominant gas-pollen. Conclusion The survey provided a reference for the epidemiological study of airborne pollen in Hohhot, which is of clinical significance for the prevention and treatment of allergic diseases associated with pollen in this area.
