摘要
目的:探讨川贝对哮喘模型小鼠血管生成的作用及机制。方法:建立哮喘模型小鼠并将小鼠随机分为模型组(OVA致敏的小鼠),中药川贝组和PBS组(正常对照组)。中药川贝组给予中药川贝(9.0g/kg),观察其对模型小鼠的气道炎症、血管生成、血管内皮生长因子(VEGF)和缺氧诱导因子-1α(HIF-1α)表达的影响。结果:与哮喘模型小鼠相比,中药川贝可以改善过敏性气道炎症,并显著减少血管百分比,同时也降低于VEGF和HIF-1α的表达。血管百分比与VEGF和HIF-1α表达呈正相关,同时与VEGF和HIF-1α表达呈正相关。结论:中药川贝具有显著的抑制哮喘模型小鼠血管生成作用,其通过抑制VEGF和HIF-1α表达发挥抗血管生成活性。
