Traumatic axonal injury (TAI), a feature of traumatic brain injury (TBI), progressively evolves over hours through impaired axonal transport and is thought to be a major contributor to cognitive dysfunction. In spite of various studies suggesting that pharmacologic or physiologic interventions might reduce TAI, clinical neuroprotective treatments are still unavailable. Edaravone, a free radical...

BACKGROUND AND PURPOSE Our previous studies have demonstrated that oxidative DNA injury occurs in the brain after intracerebral hemorrhage (ICH). We therefore examined whether edaravone, a free-radical scavenger, could reduce ICH-induced brain injury. METHODS These experiments used pentobarbital-anesthetized, male Sprague-Dawley rats that received an infusion of either 100 microL autologous w...

The data of the nationwide prospective registry of acute cerebral large vessel occlusion (LVO; RESCUE-Japan Registry) were analyzed to know the effect of edaravone, a free radical scavenger, on clinical outcome at 90 days after onset. In this registry, patients with acute cerebral LVO admitted within 24 h after onset were prospectively registered. The effect of various factors including endovas...

Edaravone (MCI-186; 3-methyl-1-phenyl-2-pyrazolin-5-one), a free radical scavenger, is used for the treatment of acute cerebral infarction. Edaravone is mainly excreted into the urine after conjugation to glucuronide or sulfate. Previous studies have demonstrated that edaravone sulfate is a good substrate of human organic anion transporter (OAT) 1 (SLC22A6) and human OAT3 (SLC22A8). In this stu...

Edaravone, a clinical drug used widely for the treatment of acute cerebral infarction, is reported to scavenge free radicals. In the present study, we investigated the radioprotective effect of edaravone on X-ray-induced apoptosis in MOLT-4 cells. Apoptosis was determined by the dye exclusion test, Annexin V binding assay, cleavage of caspase, and DNA fragmentation. We found that edaravone sign...

Background Although inflammation and free radicals have been reported to play deteriorative role in the ischemic brain lesion, the effect of free radical scavenger in ischemic stroke patients is still under debate. For exploring the hypothesis that the ischemic damage is reduced by edaravone or not, we evaluated the temporal profile of the size of ischemic stroke lesion assessed by MRI for more...

The combination of alteplase, a recombinant tissue plasminogen activator, and edaravone, an antioxidant, reportedly enhances recanalization after acute ischemic stroke. We examined the influence of edaravone on the thrombolytic efficacy of alteplase by measuring thrombolysis using a newly developed microchip-based flow-chamber assay. Rat models of embolic cerebral ischemia were treated with eit...

Edaravone is clinically used for treatment of patients with acute cerebral infarction. However, the effect of double application of edaravone on neurogenesis in the hippocampus following ischemia remains unknown. In the present study, we explored whether pre- and posttreatment of edaravone had any effect on neural stem/progenitor cells (NSPCs) in the subgranular zone of hippocampus in a rat mod...

Edaravone is a free radical scavenger that protects the adjacent cortex during cerebral infarction. We created a hemiparetic model of cerebral thrombosis from a photochemically induced infarction with the photosensitive dye, rose bengal, in rats. We examined the effects of edaravone on recovery in the model. A total of 36 adult Wistar rats were used. The right sensorimotor area was irradiated w...

PURPOSE Edaravone (MCI-186) is a newly developed antioxidative radical scavenger for the treatment of acute cerebral infarction, exerting neuroprotective effects against ischemic insult. The neuroprotective effects of edaravone on pilocarpine-induced seizures in rats were investigated. METHODS Rats were treated intraperitoneally with saline or edaravone (1-30 mg/kg), applied 30 min before pil...
