Microglial Activation in Rat Experimental Spinal Cord Injury Model
نویسندگان
چکیده مقاله:
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-µm long injured spinal cord showed a significant increase in glial cell density percentage at day 2 as compared to other days. Whereas the highest increase in ED-1 immunoreactive cells (monocyte/phagocyte marker in rats) was observed at day 2 (23.15%) post-injury. Evaluation of cavity percentage showed a significant difference between weeks 3 and 4 post-injury groups. Conclusions: This study provides a new insight into the multiphase immune response to SCI, including cellular inflammation, macrophages/microglia activation, glial cell density, and cavitation. Better understanding of the inflammatory processes associated with acute SCI would permit the development of better therapeutic strategies.

متن کاملEffect of Aspirin on Spinal Cord Injury: An Experimental Study
Aspirin is an anti-inflammatory drug, peroxyl radical scavenger, and antioxidant agent that inhibits phospholipases, nitric oxide synthetases, and cyclooxygenase enzymes. The existing literature contains no studies on the effects of various doses of aspirin on spinal cord injury (SCI). Therefore, we sought to investigate the putative effects of aspirin on experimental SCI.The weight-drop injury...

BACKGROUND The purpose of this study was to investigate the therapeutic effects and mechanisms of hyperbaric oxygen (HBO) treatment on rats following spinal cord injury (SCI). METHODS A total of 45 Sprague-Dawley (SD) rats were randomly divided into three groups. Sham-SCI group was surgically exposed but not subjected to the SCI procedure. SCI-control group was administered SCI and treated wi...
متن کاملRelating Histopathology and Mechanical Strain in Experimental Contusion Spinal Cord Injury in a Rat Model
During traumatic spinal cord injury (SCI), the spinal cord is subject to external displacements that result in damage of neural tissues. These displacements produce complex internal deformations, or strains, of the spinal cord parenchyma. The aim of this study is to determine a relationship between these internal strains during SCI and primary damage to spinal cord gray matter (GM) in an in viv...
