For decades, the primary approach and goal of therapy for stroke has focused on neuroprotection, namely treating the injured tissue, with interventions designed to reduce the volume of cerebral infarction. Enormous effort in the laboratory has been devoted to the development of neuroprotective agents in an attempt to salvage ischemic neurons in the brain from irreversible injury; however, all these efforts have failed to demonstrate efficacy in clinical trials of stroke. In order to treat stroke, we have to re-con- ceptualize and redefine our therapeutic targets. Acute neu- roprotective treatments for stroke fight a temporal battle of salvaging cerebral tissue before the onset of death, as well as a physiological impediment of delivery of therapy to tissue which has inadequate blood flow.展开更多

Clinical and experimental studies have revealed the main pathological changes of injured spinal cord implicated in all these signs and symptoms, including neuropathic pain. After few hours of traumatic SCI, it is usual to observe broken blood brain barrier with plasma and blood cells extravasation, cell necrosis, disruption of ascending and descending spinal cord pathways and increased potassium and glutamate. Glutamate contributes to excitotoxicity of neurons whereas potassium facilitates ectopic depolarization of survival neurons and activation of resident microglia.展开更多
