目的探讨丹酚酸B对鸡胚绒毛尿囊膜血管新生的影响。方法将7日龄鸡胚制备鸡胚绒毛尿囊膜(chick embryo chorioallantoic membrane,CAM)模型,随机分为6个组,分别为PBS(phosphatebuffer solution)对照组,丹酚酸B 4个剂量组(150、50、16.67、5.56 mg.L-1)及VEGF(vascular endo-thelial growth factor)组,培养3 d后时采集数据进行评价。结果丹酚酸B 150、50 mg.L-1组血管新生面积明显高于PBS(phosphate buffer solution)对照组(P〈0.01,P〈0.05)。结论丹酚酸B可明显促进鸡胚绒毛尿囊膜血管新生。
Objective To investigate the effect of sal B on angiogenesis of the chick embryo chorioallantoic membrane(CAM).Methods Forty-eight 7-day-old fertilized eggs were randomly divided into 6 groups,PBS(phosphate buffer solution)group,different concentrations of sal B(150.00,50.00,16.67 and 5.56 mg·L-1)groups and VEGF(vascular endothelial growth factor)group,the chorioallantoic membrane(CAM)models were made,and the carriers with subjects were put on the CAM.After incubation for another 3 days at 37.8 ℃ at constant humidity,their effects were evaluated.Results The angiogenesis area in sal B 150,50 mg·L-1 groups was obviously increased compared with PBS group(P0.01,P0.05).Conclusions The result shows that sal B can obviously stimulate angiogenesis of the chick embryo CAM.
