摘要: 目的 研究益气养阴方抗肿瘤诱导鸡胚尿囊膜(CAM) 血管生成及对CAM 移植瘤细胞血管内皮生长因子(VEGF) 表达的效应。 方法 制备接种肿瘤细胞的CAM 模型, 采用血清药理学方法制备含药血清。观察含药血清对肿瘤细胞诱导CAM 血管生成的影响, 并与生理盐水血清组对照。另外应用免疫组织化学及其组织形态学定量分析方法对VEGF 在CAM 移植瘤中的表达进行研究。 结果 益气养阴方含药血清可抑制肿瘤细胞诱导CAM 血管生成。益气养阴方组VEGF 的表达均明显低于对照组, 差异有统计学意义(P<0.05)。 结论 益气养阴方对肿瘤诱导的CAM 血管生成有明显抑制作用, 降低VEGF 的表达可能是其抑制肿瘤血管生成的主要机制之一。

Abstract: AIM: To study the role of Yiqiyangying Fang on angiogenesis and vascular endothelial growth factor (VEGF) in tumor cells transplanted on chick chorioallantoic membrane(CAM). METHODS: The chicken CAM model with tumor cells transplanted was adopted.The drug-contained serum was prepared using serum pharmacological method.The effect of CAM angiogenesis induced by tumor cells was observed in serum containing drugs and normal sodium serum as control group.The expression of VEGF in tumor cells transplanted on CAM was investigated by immunohistochemical analytics methods. RESULTS: The rat blood serum containing Yiqiyangying Fang inhibited angiogenesis in chicken CAM induced by tumor cells transplanted.The expression of VEGF in Yiqiyangying Fang group was lower than that in control group, there was statistical difference (P<0.05). CONCLUSION: Yiqiyangying Fang has significant inhibitory effects on angiogenesis induced by tumor cells in CAM.The down-regulation of VEGF expressions may be one of its mechanisms for inhibiting tumor angiogenesis.

Key words: Yiqiyangyin Fang, vascular endothelial growth factor, angiogenesis
