Abstract:

Objective: To investigate the distribution of pollen allergens in patients with allergic rhinitis（AR）in Baoshan, Yunnan,
and to offer basis for the diagnosis, prevention and treatment. Methods: 980 allergic rhinitis were examined by skin prick test（SPT）
with 15 kinds of pollen antigen extract of allergic rhinitis. Results: Among 980 cases, 269 cases（27.4%）were detected with one
antigen, 460 cases（46.9%）were detected with two or more antigens. The main common pollen allergens in patients with allergic
rhinitis in Baoshan were 348 cases of Gramineae（35.5%）, 310 cases of aestivo-autumnal（31.6%）, 251 cases of Chinese ash
（25.6%）, 2 cases of sakura（0.2%）which is the least one. Positive rate of pollen allergens were different between youngsters group
and middle-aged group. Conclusion: Gramineae, stivo-autumnal and Chinese ash were the main pollen allergens of allergic rhinitis in
Baoshan. Most patients with allergic rhinitis were allergic to two or more kinds of pollen allergens. Skin prick test（SPT）is helpful for
the discovery of the allergens so as to provide important basis of desensitization therapy.
