[Pro-angiogenic effects of four Chinese medicines and three herbal prescription in chicken chorioallantoic membrane model].

Objective: To observe the pro-angiogenic effect of four Chinese medicines and three herbal prescriptions,screen the effective components from them. Methods: Chicken chorioallantoic membrane( CAM) model was employed to observe the pro-angiogenic activities of Angelicae Sinensis Radix,Salviae Miltiorrhizae Radix,Notoginseng Radix,Astragali Radix,Xuefuzhuyu decoction,Dangguibuxue decoction and Taohongsiwu decoction,all of them were claimed to promote angiogenesis. The effective components were screened from the extracts. Results: Compared with negative control group,the blood vessel densities in Angelicae Sinensis Radix and Notoginseng Radix groups were not increased significantly( P 0. 05). However,blood vessel densities in Astragali Radix group,Salviae Miltiorrhizae Radix group,Xuefuzhuyu decoction group,Dangguibuxue decoction group and Taohongsiwu decoction group were notably enhanced( P 0. 05). Dangguibuxue decoction showed a more than 90% of increase in blood vessel densities as compared with the negative control group( P 0. 01),and components contained ferulic acid and astragaloside from Dangguibuxue decoction displayed significantly pro-angiogenic effect( P 0. 05). Conclusion: Dangguibuxue decoction and its extract,components contained ferulic acid and astragaloside,can improve angiogenesis in CAM model significantly.
