Methods\ An epidemiological survey on nasal allergy was carried out among 1 660 primary and middle school students and 1 620 university students, including questionnaire investigation, nasal inspection by the same doctor and scratch test with the allergen extract of Cj. The pollen of Cf and Cj were observed by optical and electron microscope. The genes of chloroplast of them were analysed. Results ①The total positive rate of cedar pollen scratch test was 4.2%. 55 cases of nasal allergy were confirmed according to the criteria of diagnosis, in which 8 cases showed positive reaction to Cj and only 1 case was hypersentive to it. ②No significant distinction between Cf and Cj was found by optical and electron microscope and no difference in gene analysis was found. Conclusion\ ①Cedar pollinosis does exist in China. It′s low prevbalence is related to the low quantity of cedar pollen.②Cf and Cj are of the same family and genus. ③There may be an increasing tendency of cedar pollinosis in China.\; 关键词：cedar cedar pollen cedar pollinosis EPIDEMIOLOGICAL
