We provide the first data that cathepsin B (Cath B), a lysosomal cysteine protease, is up-regulated following contusion-spinal cord injury (SCI). Following T12 laminectomy and moderate contusion, Cath B mRNA and protein expression profiles were examined from 2 to 168 h post-injury in rats using real-time PCR and immunoblots, respectively. Contusion injury significantly increased [mRNA]Cath B in...

Traumatic brain injury is a major cause of mortality in developed countries. Cerebral parenchymal injury is evidenced by a significant percentage of patients. The most important structural lesion of the brain is the cerebral contusion, which is a complex and dynamic area, a result of the primary lesion and which is associated with ischemic and inflammatory phenomena that need to be known by the...

BACKGROUND Cardiac contusion is an important cause of mortality after blunt chest trauma (BCT). The aim of this study was to investigate the therapeutic efficacy of the usage of aminoguanidine (AG), in myocardial damage occurring after BCT, alone and in combination with methylprednisolone (MP). METHODS Thirty-five female Wistar albino rats were randomly assigned to five groups (n = 7) includi...

Introduction The adult respiratory distress syndrome (ARDS) represents a final common pathway of injury due to a large variety of massive, often unrelated, insults to the lung (Table 1). For example, the injury may be a consequence of direct pulmonary damage such as aspiration ofgastric contents or pulmonary contusion or the result of a systemic process such as sepsis or cardiopulmonary bypass....

Lipocalin 2 (Lcn2) plays an important role in defense against bacterial infection by interfering with bacterial iron acquisition. Although Lcn2 is expressed in a number of aseptic inflammatory conditions, its role in these conditions remains unclear. We examined the expression and role of Lcn2 after spinal cord injury (SCI) in adult mice by using a contusion injury model. Lcn2 expression at the...

While many studies have focused on modulating the immune response and enhancing axonal regeneration after spinal cord injury (SCI), there is limited work being performed on evaluating the role of glial scar in SCI. We sought to evaluate the effects of glial scar resection in contusion models and dorsal hemisection models of SCI. At 1-week postinjury, 2 mm of glial scar was excised from specimen...

Abstract Background Traumatic asphyxia, also called masque ecchymotique, Ollivier’s syndrome, and Perthes is a rare but serious form of chest trauma described for the first time by Ollivier in 1837. The purpose this study to report our experience with two cases traumatic asphyxia discuss their management view relevant literature. Results During 6-year period, author treated 2 (crush) local teac...

We have previously reported that administration of a CD11d monoclonal antibody (mAb) improves recovery in a clip-compression model of SCI. In this model the CD11d mAb reduces the infiltration of activated leukocytes into the injured spinal cord (as indicated by reduced intraspinal MPO). However not all anti-inflammatory strategies have reported beneficial results, suggesting that success of the...
