摘要:目的:探讨当归对阴虚哮喘BALB/c小鼠气道MUC5AC及相关炎症因子表达的影响。方法:取雌性小鼠随机分7组(n=12),通过注射卵清白蛋白(OVA)致敏、吸入OVA激发复制哮喘模型,实验后期给予甲状腺素以复制阴虚哮喘BALB/c小鼠模型;在受试药的干预下,观测当归对哮喘行为学、肺组织病理学、BALF中活性因子(包括IL-13、TNF-α、MUC5AC)及肺组织中MUC5AC表达的影响。结果:2、4、8 g/kg当归可明显降低哮喘行为学综合评分,缓解肺组织病理学变化,降低BALF中IL-13、TNF-α及MUC5AC的水平,抑制肺组织中MUC5AC的表达(P<0.05,0.01)。同时,当归与地塞米松配伍后抑制IL-13与MUC5AC表达有一定的协同作用(P<0.05)。结论:当归对哮喘具有一定的治疗作用,通过抑制IL-13、TNF-α而调节MUC5AC的表达可能是其作用机制之一,而在调节IL-13与MUC5AC的表达方面当归与糖皮质激素有一定的协同作用。
Objective:To study the effects of Radix Angelicae Sinensis (RASI) on expression of airway MUC5AC and related inflammatory factors in asthmatic mice with Yin deficiency syndrome. Methods: Injecting ovalbumin (OVA) to sensitize,inhaling OVA to stimulate, using Thyroxin during late stimulation, the asthmatic mouse with Yin deficiency syndrome was established and evaluated through asthmatic behaviors, lung histopathology, active factors (IL-13, TNF-α and MUCSAC) in broncho-alveolar lavage fluid (BALF), and MUC5AC expression in lung tissue. Results: 2, 4, 8 g/kg RASI could reduce asthmatic behaviors score, relieve pathological changes of lung tissue, reduce the contents of IL-13, TNF-α and MUC5 AC in BALF, and depress MUC5AC expression in lung tissue (P〈0. 05,0. 01 ). In addition,there was a certain synergy between RASI and dexamethasone (DXM) on depressing the ex- pression of IL-13 and MUC5AC (P〈0. 05). Conclusion: RASI has certain anti-asthma effect and one of mechanisms is to regulate the MUCSAC expression through inhibit IL-13 and TNF-α. On the expression of IL-13 and MUC5AC, the compatibility of RASI with glu- cocorticoid has some synergy effect.
