中文摘要：

目的：探讨直流电场（electric fields．EF）对血管生成的影响及作用机制。方法：于发育第8天的鸡胚绒毛尿囊膜（chick embryo chorioallantoic membrane，CAM）上植入明胶海绵载体，其中加载不同强度EF，计数长入载体的血管和载体内的微血管密度（microvascular densily．MVD）。结果：150mV／mm、200mV／mm组在CAM上长入载体边缘的血管数和MVD与对照组间的有显著差别（p〈0．01）。结论：强度为150mV／mm、200mV／mm的直流电场能促进CAM的血管生成。

英文摘要：

Objective： The study was to reveal the effect of direct electric fields on angiogenesis of chick embryo chorioallantoic membrane（CAM）. Methods： Gelatin sponges were implanted on top of CAM, when chick embryos developed on the 8th day, vessels which towards gelatin and microvascular density（MVD） in gelatin were counted on the 12th day. Results： On CAM model, numbers of vessels at the sponge-CAM boundary and MVD were significantly different between group of 150 mWmm, 200 mV/mm and group of saline （p〈 0. 01）. Conclusions： The study has shown that direct electric fields, 150 mV/mm and 200 mV/mm, could promote the angiogenesis on CAM model.
