BACKGROUND Extensive burn injury leads to production of free radicals subsequent to massive fluid resuscitation, which in turn increases the risk of acute lung injury. Edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one), a novel free radical scavenger, is clinically effective in improving the prognosis after cerebral infarction. However, the effect of edaravone against extensive burn injury has not...

Introduction: Edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one) of a free radical scavenger has been widely used in treatment of acute ischemic stroke. However, effects of edaravone on hypoxic astrocytes have not been fully understood. Therefore, we investigated the effects by proteomic analysis. Methods: We cultured human astrocytes under hypoxia and normoxia with or without edaravone. Then, we ...

Angiotensin II (Ang II) is known to be involved in the progression of ventricular dysfunction and heart failure by eliciting cardiac fibrosis. The purpose of this study was to demonstrate whether treatment with an antioxidant compound, edaravone, reduces cardiac fibrosis and improves ventricular function by inhibiting Ang II AT1 receptor. The study was conducted in a rat model of transverse aor...

Introduction: This study investigates the relationship between the mechanism of traumatic brain injury and free radicals, and the influence of a novel free radical scavenger, edaravone, on experimental brain injury. Materials and Methods: Male Wistar rats were anesthetized with 1–2% halothane in a mixture of 50% oxygen and 50% air. Brain injury was produced using a controlled cortical impact in...

3-methyl-1-phenyl-2-pyrazolin-5-one (edaravone), an effective free radical scavenger, provides neuroprotection in stroke models and patients. In this study, we investigated its neuroprotective effects in a chronic rotenone rat model for Parkinson's disease. Here we showed that a five-week treatment with edaravone abolished rotenone's activity to induce catalepsy, damage mitochondria and degener...

BACKGROUND AND PURPOSE Hypoperfusion-induced thrombosis is an important mechanism for postsurgery stroke and cognitive decline, but there are no perioperative neuroprotectants to date. This study investigated whether prophylactic application of Edaravone, a free radical scavenger already used in treating ischemic stroke in Japan, can prevent infarct and cognitive deficits in a murine model of t...

Free radicals play major roles in the pathogenesis of tissue damage in many diseases and clinical conditions, and the removal of free radicals may offer a treatment option. Several modulators of free radical scavenger pathways have been developed and some have progressed to clinical trials. One such agent, edaravone, was approved in 2001 in Japan ...

UNLABELLED Refractory wound healing is a major complication of diabetes, which restricts wound healing by interfering with the inflammatory response, decreasing granulation, causing peripheral neuropathy, and inhibiting angiogenesis. Oxidative stress has been proposed as an important pathogenic factor in diabetic wound complications. Edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one) is a strong f...

background: cyclosporine a (csa) is an immunosuppressant with therapeutic indications in various immunological diseases; however, its use is associated with chronic nephropathy. oxidative stress has a crucial role in csa-induced nephrotoxicity. the present study evaluates the protective effect of edaravone on csa-induced chronic nephropathy and investigates its antioxidant and nitric oxide modu...

Traumatic brain injury (TBI) is a major cause of death and disability in young people. No effective therapy is available to ameliorate its damaging effects. Our aim was to investigate the optimal therapeutic time window of edaravone, a free radical scavenger which is currently used in Japan. We also determined the temporal profile of reactive oxygen species (ROS) production, oxidative stress, a...
