Background: Reduction of permanent or transient cerebral blood flow may lead to some structural and functional changes of the brain, causing high mortality and morbidity. The aim of this experimental study was to investigate the effects of hydroalcoholic extract of Nigella sativa (NS) on markers of cerebral angiogenesis in rats induced by global brain ischemia. Methods: Thirty-two male Wistar rats (250 +/- 20 g) were randomly divided into 4 groups: group 1, control group receiving only normal saline; group 2, sham group undergoing surgery and stroke induction without treatment; and groups 3 and 4 treated with 10 and 20 mg/kg NS, respectively, after induction of stroke. Global ischemia was induced by ligation of the right carotid artery for 20 minutes. Results: According to the results of this study, brain edema and infarct volume were significantly decreased in the group treated with 20 mg/kg NS compared with the group treated with 10 mg/kg NS (P < .05). Global ischemia caused a significant reduction in gene expression of vasoactive endothelial growth factor (VEGF) and hypoxia-inducible factor (HIF) in the sham group compared with the control group (P < .05), but NS groups, in led to a significant increase in gene expression of VEGF and HIF compared with the sham group (P < .05). In addition, the activity level of matrix metallopeptidase-9 was decreased among NS groups compared with the control group (P < .05). Conclusions: Application of NS extract among rats with brain ischemia is associated with increase of VEGF and HIF as angiogenic markers and inhibition of matrix metallopeptidase-9 activities.
