摘要：In this study, we studied electromagnetic field effect on angiogenesis. Ross fertilized eggs were used that divided into 3 random groups 42 consisted of control, sham-exposed and a test group which treated by 0.04 T electromagnetic field. In day 10 members of test group was occurred in 0.04 T electromagnetic fields for 4 h. Members of sham-exposed group was occurred in the same electromagnetic field but in turn off condition. In day 12 chorioalantoic membranes were examined and photographed in all cases. The numbers and lengths of vessels in four random same areas were measured and compared with each other by t-test (p<0.05). Comparison between average number and length of vessels in controls and sham-exposed didn't show any significant differences. In test group we saw a significant decrease in average number (26.69±7.88) and length (44.41±9.88 cm) of vessels in comparison with controls. As a result 0.04 T electromagnetic field has an inhibitory effect on angiogenesis in chick chorioalantoic membrane.
