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。
目的：探討川貝對哮喘模型小鼠血管生成的作用及機製。方法：建立哮喘模型小鼠併將小鼠隨機分為模型組（OVA緻敏的小鼠），中藥川貝組和PBS 組（正常對照組）。中藥川貝組給予中藥川貝（9.0g/kg），觀察其對模型小鼠的氣道炎癥、血管生成、血管內皮生長因子（VEGF）和缺氧誘導因子-1α（ HIF-1α）錶達的影響。結果：與哮喘模型小鼠相比，中藥川貝可以改善過敏性氣道炎癥，併顯著減少血管百分比，同時也降低于VEGF和HIF-1α的錶達。血管百分比與VEGF和HIF-1α錶達呈正相關，同時與VEGF和HIF-1α錶達呈正相關。結論：中藥川貝具有顯著的抑製哮喘模型小鼠血管生成作用，其通過抑製VEGF和HIF-1α錶達髮揮抗血管生成活性。

Objective:To determine the effects and mechanisms of Bulbus Fritillariae Cirrhosae on angiogenesis in murine asthma models .Methods:Murine asthma models were established and mice were divided into three groups:the model group ( OVA-sensitized and challenged mice ) , the BFC group ( Bulbus Fritillariae Cirrho-sae -treated mice) and the PBS group (normal control mice).Mice in the BFC group were administered with inhaled Bulbus Fritillariae Cirrhosae (9.0g/kg) daily.The effects on airway inflammation, angiogenesis, ex-pression of hypoxia inducible factor -1α( HIF-1α) and vascular endothelial growth factor ( VEGF) were ex-amined.Results:Administration of Bulbus Fritillariae Cirrhosae ameliorated allergic airway inflammation and significantly reduced the percentage vascularity compared with those in the asthmatic model mice .It also re-duced the expression of HIF -1α, as well as that of VEGF.Percentage vascularity had a positive correlation with both HIF-1αand VEGF expressions .Furthermore , there was a positive relationship between HIF -1αand VEGF expressions .Conclusion:The results demonstrate that Bulbus Fritillariae Cirrhosae has an important inhibitory effect on angiogenesis in asthma .Inhaled administration of Bulbus Fritillariae Cirrhosae can achieve anti-angiogenic activity through inhibition of HIF -1αand VEGF expressions .
