STUDY DESIGN The effect of edaravone, a novel free radical scavenger, was assessed functionally and histologically using a rat spinal cord contusion model. OBJECTIVE To investigate the effect of edaravone on neuroprotection after spinal cord injury in rats. SUMMARY OF BACKGROUND DATA The spinal cord injury results in immediate physical damage (primary injury), followed by a prolonged neural...

UNLABELLED Lysophosphatidic acid (LPA) is an extracellular lipid mediator involved in many physiological functions that signals through six known G-protein-coupled receptors (LPA1-LPA6). A wide range of LPA effects have been identified in the CNS, including neural progenitor cell physiology, astrocyte and microglia activation, neuronal cell death, axonal retraction, and development of neuropath...

By reducing the progressive degeneration and disconnection of axons following spinal cord injury the functional outcome should improve. After direct transection of dorsal column sensory axons, neurotrophin-3 (NT-3) treatment can reduce degeneration and promote regeneration of the proximal stumps. Here, we tested in adult rats whether NT-3 infusion at the site of a moderate T9 spinal cord contus...

Objective(s): Pulmonary contusion (PC) is a clinical entity that often accompanies blunt traumas. We aimed to investigate the radiological and histopathological effects of surfactant treatment in an experimental rat model in which lung contusion was formed by blunt thoracic trauma.Materials and Methods: 50 female Sprague-Dawley rats were...

Despite the vast improvements of cell therapy in spinal cord injury treatment, no optimum protocol has been developed for application of neural stem/progenitor cells. In this regard, the present meta-analysis showed that the efficacy of the neural stem/progenitor cell (NSPC) transplantation depends mainly on injury model, intervention phase, transplanted cell count, immunosuppressive use, and p...

To explore the effect of electroacupuncture on spinal cord injury (SCI) involving immune-related factors and regeneration-related in rats. The model contusion was established by PCI 3000 instrument. Two types acupuncture points were selected for treatment rats tested once a week, fiber remodeling detected magnetic resonance imaging. Transcriptome sequencing performed scar samples. Using Python ...

The heat shock protein 72 (HSP 72) is a universal marker of stress protein whose expression can be induced by physical exercise. Here we report that, in a localized model of spinal cord injury (SCI), exercised rats (given pre-SCI exercise) had significantly higher levels of neuronal and astroglial HSP 72, a lower functional deficit, fewer spinal cord contusions, and fewer apoptotic cells than d...

To evaluate the hypothesis that calpain 1 knockdown would reduce pathological damage and functional deficits after spinal cord injury (SCI), we developed lentiviral vectors encoding calpain 1 shRNA and eGFP as a reporter (LV-CAPN1 shRNA). The ability of LV-CAPN1 shRNA to knockdown calpain 1 was confirmed in rat NRK cells using Northern and Western blot analysis. To investigate the effects on sp...

PURPOSE To define the clinical and prognostic role of MR in a pediatric population with spinal cord injury. METHODS Fifteen children underwent MR 12 hours to 2 months postinjury using decoupled surface coils and ventilator support as needed. MR was correlated retrospectively with clinical, CT, and radiographic findings. RESULTS On MR, of seven children with spinal cord neurologic deficits, ...
