STUDY DESIGN Examination of hyaluronidase-4 (Hyal-4) expression in a rat spinal cord hemisection model. PURPOSE To determine the status of Hyal-4 expression after hemisection of the spinal cord, and the relationship between its expression and that of chondroitin sulfate proteoglycans (CSPGs). OVERVIEW OF LITERATURE CSPGs are expressed at the site of spinal cord injury and inhibit axon regen...

BACKGROUND AND OBJECTIVES Light therapy has biomodulatory effects on central and peripheral nervous tissue. Spinal cord injury (SCI) is a severe central nervous system trauma with no effective restorative therapies. The effectiveness of light therapy on SCI caused by different types of trauma was determined. STUDY DESIGN/MATERIALS AND METHODS Two SCI models were used: a contusion model and a ...

Loss of respiratory function is one of the leading causes of death following spinal cord injury. Because of this, much work has been done in studying ways to restore respiratory function following spinal cord injury (SCI) - including pharmacological and regeneration strategies. With the emergence of new and powerful tools from molecular neuroscience, new therapeutically relevant alternatives to...

Objective(s): AMP-activated protein kinase/sirtuin 1 (AMPK/SIRT1) signaling pathway has been proved to be involved in the regulation of autophagy in various models. The aim of this study was to evaluate the effect of AMPK/SIRT1 pathway on autophagy after spinal cord injury (SCI). Materials and Methods:The SCI model was established in rats in vivo and the primary spinal cord neurons were subject...

background: neutrophil infiltration plays an important role in inflammatory reactions following spinal cord injury (sci) and these cells cause substantial secondary tissue damage. the purpose of this study was to determine the effect of oleuropein (oe) on myeloperoxidase (mpo) activity as an index of neutrophil infiltration. methods: rats were randomly divided into four groups of 7 rats each as...

Background: Spinal cord injury (SCI) refers to spinal cord damage arising from trauma, disease or degeneration. At present, there is still no treatment for any paraplegia resulting from SCI. We have previously shown that very low intensity, low frequency, electromagnetic field treatment (VLIFE) promotes neuronal plasticity after stroke and as a result, improves clinical recovery. Objective: In ...

An important barrier for axon regeneration and recovery after traumatic spinal cord injury (SCI) is attributed to the scar that is formed at the lesion site. Here, we investigated the effect of mouse mast cell protease (mMCP) 6, a mast cell (MC)-specific tryptase, on scarring and functional recovery after a spinal cord hemisection injury. Functional recovery was significantly impaired in both M...

Mechanisms of oligodendrocyte death after spinal cord injury (SCI) were evaluated by T9 cord level hemisection in wild-type mice (C57BL/6J and Bax+/+ mice), Wlds mice in which severed axons remain viable for 2 weeks, and mice deficient in the proapoptotic protein Bax (Bax-/-). In the lateral white-matter tracts, substantial oligodendrocyte death was evident in the ipsilateral white matter 3-7 m...

Objective(s) Recent studies revealed the neuroprotective effects of epigallocatechin gallate (EGCG) on a variety of neural injury .The purpose of this study was to determine the effects of EGCG on the tissue lipid peroxidation after spinal cord injury (SCI). Materials and Methods Rats were randomly divided into four groups of 7 rats each as follows: sham-operated group, trauma group, and EGC...
