摘要: 目的: 探讨白细胞介素-1 受体拮抗剂(IL-1ra)与哮喘的气道高反应性(AHR)的关系。方法: 正常豚鼠,先腹腔注射卵清蛋白(OA)致敏而后雾化吸入OA激发豚鼠哮喘(哮喘组),激发前30min静脉注射IL-1ra 1mg·kg-1(哮喘+IL-1ra 组),测定豚鼠的气道反应性(组胺的PC20值),并收集支气管肺泡灌洗液(BALF)进行细胞总数计数及分类记数。结果: 哮喘+IL-1ra 组PC20 值与对照组无显著性差异(P>0.05),显著高于哮喘组(P<0.01);BALF 中的中性粒细胞(NES)的百分比显著低于哮喘组(P<0.01)。所有豚鼠均存在-IgPC20值与BALF中的NES的百分比呈正相关(r=0.95,P<0.001)。结论: IL-1ra能降低AHR,其机制可能与IL-1ra减少NES的浸润有关。

Abstract: AIM: To explore the relationship between interleukin-1receptor antagonist (IL-1ra) and airway hyperresponsiveness (AHR) of asthma.METHODS: The airway responsiveness to inhaled histamine as PC20 was evaluated among the normal guinea pigs, and sensitized with ovalbumine (OA) and challenged 14 days later (athma group), and injected IL-lra 1 mg·kg-1 intravenously 30 minutes before challenged (asthma plus IL-lra group).The numbers of different cells was counted and classified in bronchoalveolar lavage fluid (BALF).RESULTS: The PC20 of the asthma plus IL-1ra group was higher than that of asthma group (P<0.01), and the percentage of the neutrophils (NES) in BALF of the asthma plus IL-1ra group was lower than that of the asthma group (P<0.01).There was a significant correlation between -IgPC20 and the percentage of the NES in BALF in all animals(r=0.68,P<0.001).CONCLSION: IL-1ra can attenuate airway hyperresponsiveness, possibly by decreasing the airway infiltration of neutrophils.
