Antiangiogenic Effects of Eugenol in Chorioallantoic Membrane of Chick Embryo

Introduction: Eugenol is a substance obtained from clove that has some therapeutic properties. Angiogenesis involves the formation of new blood vessels from the primary vessels. Since today natural products are taken into consideration in regard with anti-angiogenic therapies, this study intended to investigate anti-angiogenic effects of eugenol on chorioallantoic membrane (CAM) of chick embryo. Methods: In this experimental study, 70 Ross fertilized eggs were randomly divided into: control, sham and five experimental groups. On the 8th day of incubation, experimental groups were treated with 0.5 -5 mM of eugenol. On the 12th day, all cases were photographed and the numbers and lengths of vessels around the sponges were measured via applying image J software. Furthermore, the hemoglobin content was measured using Drabkin test, and then the embryo weight was recorded. The study data were analyzed statistically via SPSS software utilizing ANOVA test at significance level of p
