Introduction: Angiogenesis is regarded as a complex activity required for physiological process as well as many pathological conditions as solid tumor progression and metastasis. Stachys Lavandulifolia of Laminacea family prossesses antioxidant and anti-apoptosis effects. Therefore, this study aimed to investigate the effect of Stachys Lavandulifolia alcoholic extract on angiogenesis in chorioallantoic membrane of Ross chicken embryo.

Methods: In this experimental study, 30 Ross fertilized eggs were divided into 5 random groups consisting of: control, sham-exposed, treatment with 25, 50, 100 mg/kg doses of alcoholic extract. On the 2nd day of incubation, windows were opened for eggs under the sterile conditions. On the 8th day, a gelatine sponge with 1×4×4 diameter (Albumen and Agar solution in normal saline) was placed on chorioalantoic membrane (CAM) to which extract was added. On the 12th day, length and weight as well as chorioallantoic membrane (CAM) of embryos were photographed. Then, the number and length of vessels in a special area on the CAM were measured by Image J. The study results were analyzed by Minitab (16) via applying t-test and ANOVA.

Results: Length and weight mean of embryos as well as number and length of vessels in control and
sham-exposed groups did not show any significant differences. Length and weight mean of embryos and vessels length in all treatment groups demonstrated a significant difference compared to the sham group, Moreover, mean of vessel number did not reveal any significant differences in dose of 50.

Conclusion: As the study findings indicated, the effect of this extract is dose dependet, so as it demonstrates pro angiogenesis in low doses and anti-angiogenesis effect in high doses.
