摘要
目的 探讨薏苡仁注射液对肿瘤血管形成抑制作用。方法 通过建立动物肿瘤模型 ,运用薏苡仁实验治疗 ,检测其抑瘤率和肿瘤内血管密度 ,以及瘤体VEGF和bFGF表达的改变。结果 薏苡仁具有明显的抑制S180肉瘤生长作用。实验组的S180瘤体内微血管密度均明显低于对照组 ;免疫组化显示薏苡仁大、中剂量组均可下调S180瘤体内VEGF、bFGF的表达。结论 薏苡仁注射液对肿瘤血管形成均有明显抑制作用 ,降低VEGF、bFGF的表达可能是其抑制肿瘤血管形成的主要机制之一。
Objective To investigate the effect of inhibiting angiogenesis by coix lacryma-jobi.Methods The tumor inhibitory rate and the vascular density were tested in animal tumor model with experimental treatment. The expression of VEGF and bFGF were measured by immunohistochemistry.Results Coix lacryma-jobi has inhibitory effect on S180 sarcoma and the vascular density of S180 sarcoma were lower than the control group. The expression of VEGF and bFGF were down-regulated when the middle and high dose were used.Conclusion Coix lacryma-jobi injection has inhibitory effects on S180 sarcoma and strong inhibitory effects on angiogenesis. Its mechanism may be associated with the down-regulating of VEGF and bFGF expression.
