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

Аннотация

The neuroprotective effect of ubiquinone (coenzyme Q₁₀)was demonstrated on the rats model of ischemic stroke provoked by persistent 24-h occlusion of the middle cerebral artery. Coenzyme Q₁₀ (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.
