Microglial Activation in Rat Experimental Spinal Cord Injury Model
Background: The present study was designed to evaluate the secondary microglial activation processes after spinal cord injury (SCI). Methods: A quantitative histological study was performed to determine ED-1 positive cells, glial cell density, and cavitation size in untreated SCI rats at days 1, 2, and 4, and weeks 1, 2, 3, and 4. Results: The results of glial cell quantification along the 4900...
متن کاملIn vivo diffusion tensor imaging of rat spinal cord with echo planar imaging.
The in vivo apparent diffusion tensor (ADT) of spinal cord was measured in nine rats at 2.0 T using an interleaved multi-shot echo planar imaging (EPI) diffusion sequence. A technique that combines sliding acquisition and phase correction, based on a calibration scan, to reduce ghosting artifacts in the images introduced by the strong diffusion-sensitizing gradients was described. Two rotationa...
متن کاملDiffusion Imaging in the Rat Cervical Spinal Cord
Magnetic resonance imaging (MRI) is the state of the art approach for assessing the status of the spinal cord noninvasively, and can be used as a diagnostic and prognostic tool in cases of disease or injury. Diffusion weighted imaging (DWI), is sensitive to the thermal motion of water molecules and allows for inferences of tissue microstructure. This report describes a protocol to acquire and a...

متن کاملComparative Analysis Between Thoracic Spinal Cord and Sacral Neuromodulation in a Rat Spinal Cord Injury Model: A Preliminary Report of a Rat Spinal Cord Stimulation Model
OBJECTIVE The purpose of this study is to compare a neuroprotective effect of thoracic cord neuromodulation to that of sacral nerve neuromodulation in rat thoracic spinal cord injury (SCI) model. METHODS Twenty female Sprague Dawley rats were randomly divided into 4 groups: the normal control group (n=5), SCI with sham stimulation group (SCI, n=5), SCI with electrical stimulation at thoracic ...
