Neuroprotective Effectiveness of Intravenous Ubiquinone in Rat Model of Irreversible Cerebral Ischemia

The neuroprotective effect of ubiquinone (coenzyme Q(10))was demonstrated on the rats model of ischemic stroke provoked by persistent 24-h occlusion of the middle cerebral artery. Coenzyme Q(10) (30 mg/kg) was injected intravenously in 60 min after artery occlusion. Ubiquinone crossed the blood-brain barrier, accumulated in the brain, and produced a neuroprotective effect: it alleviated ischemia-induced neurological deficit and reduced the size of necrotic zone by 49% in comparison with rats receiving physiological saline.
