- Abstract
Introduction: The death of neurons and cerebral edema are the main consequences of stroke. However, inflammatory processes play key roles in aggravating cerebral damage following a stroke. This study aimed to investigate the effects of Viola odorata extract (VOE) on the infarct volume (IV), neurologic deficits (ND), and the expression of NF-κB and VCAM-1 in the Middle Cerebral Artery Occlusion (MCAO) model. Methods: The animals were randomly separated into 6 groups: (1) control group, (2) vehicletreated group, (3) MCAO group, (4) VOE25 group, (5) VOE50 group, and (6) VOE75 group (n= 12). VOE (25, 50, and 75 mg/kg) and distilled water were administered daily for 30 days. Two hours after the last gavage, the rats were exposed to MCAO for 60 minutes. Twenty-four hours later, IV, ND, and NF-κB/VCAM-1 expressions were evaluated. Results: Viola odorata extract exhibited excellent neuroprotective effects by reducing IV (mainly in the core and subcortex areas), and induced downregulation of NF-κB and VCAM-1 expression. Conclusion: Viola odorata could also activate intracellular pathways, reducing the expression of NF-κB and VCAM-1. It is useful for developing a novel medical herb for treating cerebral ischemia.
