摘要:目的:研究当归精油对实验性哮喘大鼠模型的平喘作用及对肺脏IL-10与Foxp3表达的影响。方法:取雌性大鼠随机分6组(n=9),通过注射卵白蛋白(OVA)和氢氧化铝致敏与OVA雾化吸入激发复制哮喘模型,经当归精油干预,观测哮喘大鼠肺功能、哮喘行为学、支气管肺泡灌洗液(BALF)中IL-10(ELISA法)以及肺组织Foxp3(免疫组化法)的表达。结果:40~160 mg/kg当归精油可明显改善哮喘大鼠的肺功能,减轻吸入混合激发液后的哮喘等行为学症状,提高BALF中IL-10的水平及肺组织Foxp3蛋白的表达强度。结论:当归精油具有一定的平喘作用,而改善Treg细胞免疫功能异常低下是其作用机制之一。
Objective: To study the effects of Volatile Oil of Radix Angelicae Sinensis (VOA)on experimental asthma in rat model based on abnormal immune functions of Treg cells. Methods: After grouping, the asthmatic rats were developed through injecting OVA and AI(OH)3 for sensitization and then administering OVA aerosol for challenge, and the respiratory functions, asthmatic behaviors, IL-IO levels in broncho- alveolar lavage fluid(BALF) (ELISA) and Foxp3 expression (immunohistochemistry) in lung of asthmatic rats were observed. Rmdts: VOA at the doses of 40 ~ 160 mg/kg could improve the respiratory functions and the asthmatic behaviors, and upgrade IL-10 levels in BALF and Foxp3 expression in lung of asthmatic rats. Conclusion: VOA has some effects of anti-asthma and one of the mechanisms is to improving the lower immune functions of Treg cells.
