3 Definition and Prevalence of Allergic Rhinitis (AR) AR = IgE-mediated inflammation of the nasal mucosa AR is one of the most common chronic conditions, particularly in subjects under million sufferers worldwide, 250 million in China - Up to 40% of children IgE = immunoglobulin E. Bousquet et al. J Allergy Clin Immunol. 2001;108 (5 suppl):s147; Bauchau and Durham. Eur Respir J. 2004;24:758; Linneberg. BMJ. 2005: ; Wjst et al. PLoS Med. 2005;2:e294; Jarvis et al.

35 使用說明拔開防塵蓋 ( 圖 A) 37

36 使用說明使用前應充分振搖容器第一次使用時, 以大拇指支撐瓶底, 食指和中指壓住瓶身白色的頸部往下壓, 以將幫浦引流 ( 圖 B) 壓放幫浦約 6~7 次, 直到均勻的噴霧產生此時噴霧幫浦已可使用如果已有 14 天或更久未曾使用, 下次使用前應重新引流 38

37 使用說明輕輕自鼻中吹氣以清潔鼻孔壓住一邊鼻孔頭部向前微傾, 持瓶身向上, 小心將噴頭伸進鼻孔 ( 圖 C) 以大拇指支撐瓶底, 食指和中指壓住瓶身白色的頸部充分一次壓到底是一個噴劑量, 噴完後自此鼻孔輕輕吸氣 39

38 使用說明另一邊鼻孔重覆上述動作將防塵蓋蓋回另一邊鼻孔重覆上述動作 40

39 清洗方法清潔噴頭時, 拔下防塵蓋, 輕輕自白色頸部將噴頭拔起, 與防塵蓋一起用冷水沖洗待乾後將其裝回原位 41
