Background: Angiogenesis is said to be the formation of new capillaries from existing vascular network. One of the
effective factors on angiogenesis is endothelial growth factor (VEGF), which with its receiver plays an important role
in angiogenesis. Olive leaf through combination of polyphenols and flavonoids in itself has anti-oxidant and antiinflammatory
effects as well as the direct and indirect effects on VEGF gene expression.
Methods: In this interventional study, male Wistar rats were divided into 4 groups. In ischemia groups, gastrocnemius
artery was blocked after anesthesia with ketamine. For 21 days, the control groups (sham-ischemia) and the
treatment groups (sham- ischemia), took normal saline and olive leaf extract orally (300 mg/kg), respectively. After
anesthesia, the rats Gastrocnemius muscle were separated from the body. VEGF gene expression in muscle tissue was
measured by Real Time PCR method.
Results: In this study, the mean of VEGF gene expression in the treatment ischemia group (300 mg/kg) significantly
decreased as compared to that of the control ischemia group (P?.007). VEGF gene expression was more decreased in
the treatment sham group than in the ischemia control group, and this reduction was significant (P?.045). no
significant difference was observed in gene expression between the two treatment sham and ischemia groups
(P?.467).
Conclusion: According to the results, olive leaf extract reduces VEGF gene expression in the ischemic muscle.
