氟尿嘧啶抗血管生成作用的实验研究

The experimental study of 5-FU on inhibiting angiogenesis

目的 :探讨氟尿嘧啶 (5 FU)的抗血管生成作用。 方法 :以人脐静脉内皮细胞 (HUVEC)原代培养模型 ,MTT法测定 5 FU对HUVEC增殖的影响 ;采用鸡胚尿囊膜血管形成模型 (CAM模型 ) ,观察 5 FU对鸡胚尿囊膜新生血管的抑制作用。 结果 :5 FU在非细胞毒浓度下可在体外抑制HUVEC的增殖 ,在体内抑制鸡胚尿囊膜新生血管形成。 结论 :5 FU在非细胞毒浓度下具有抗血管生成作用。

Objective:To investigate the antiangiogenesis ability of 5 FU. Methods:Human umbilical vein endothelial cells were cultured primarily in vitro and influence of 5 FU on HUVEC proliferation was evaluated by MTT method. Chick chorilallantoic membranes(CAM) model was used to check whether the neovascularization of CAM could be suppressed in vivo . Results:5 FU both inhibited proliferation of HUVEC in vitro and suppressed angiogenesis of CAM in vivo at none cytotoxic doses. Conclusion: 5 FU demonstrated antiangiogenesis ability without obvious cytotoxicity.
