鼻息肉以慢性嗜酸细胞性炎症为特征,常与鼻炎和哮喘合并存在。但在许多鼻息肉病例中未能发现变态反应病因,为探讨鼻息肉形成与变态反应的关系,进行该项分组对比研究。四组病例分别为:鼻息肉合并豚草过敏(PRW+)组,鼻息肉不合并豚草过敏(PRW-)组,无鼻息肉但有豚草过敏(NPRW+)组,无鼻 Nasal polyps are characterized by chronic eosinophilic inflammation, often associated with rhinitis and asthma. However, in many cases of nasal polyps failed to find the cause of allergy, nasal polyps to explore the relationship between the formation and allergy, the sub-group comparative study. Four groups of patients were: nasal polyps with ragweed allergy (PRW +) group, nasal polyps without ragweed allergy (PRW-) group, no nasal polyps with ragweed allergy (NPRW +) group, no nasal polyps
