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...

balint’s syndrome is a rare neurological disorder associated with bilateral parieto-occipital damage which was described by rezsö bálint in 1909.the syndrome is manifested clinically by the presence of a hemispatial negligence. the lesion is usually inside parietooccipital region bilaterally in most cases but may also be compromised angular convolutions, the dorsolateral area of the occipital l...

We used a new approach, termed dynamic cortical deformation (DCD), to study the neuronal, vascular, and glial responses that occur in focal cerebral contusions. DCD produces experimental contusion by rapidly deforming the cerebral cortex with a transient, nonablative vacuum pulse of short duration (25 milliseconds) to mimic the circumstances of traumatic injury. A neuropathological evaluation w...

This study was designed to determine the effect of erythropoietin (Epo) on cerebral blood flow (CBF), nitric oxide (NO) concentration, and neurological outcome after traumatic brain injury. In one experiment, the hemodynamic effects of Epo were determined after controlled cortical impact injury (CCII) by measuring mean arterial pressure, intracranial pressure, CBF using laser Doppler flowmetry,...

Text of Abstract Liability to develop posttraumatic epilepsy (PTE) correlates in a general way with trauma dose. While contusion of the brain produces an admixture of extravasated blood, edema fluid and necrotic tissue at the site of skull trauma and in regions remote from the direct force, an unpredictable cascade of shearing injury, torsion and rotation and a myriad of physiological changes o...

Results Of the 132 cases referred for CT brain, 109 had a GCS score of less than 13 on initial evaluation. Among 109 cases with MHI, 90 were males and 64 (58.7%) were in the age group of 14-44 years. 78 cases were Road Traffic Accident victims, 17 were assaulted and 14 had history of fall. Twenty six (23.9%) had abnormal CT findings. Skull fracture was the commonest finding (19,17.4%), followed...

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...

Angiogenesis following traumatic brain injury (TBI) may be of importance not only for post-traumatic reparative processes but also for the development of secondary injuries. Vascular endothelial growth factor (VEGF) is a major regulator of endothelial cell proliferation, angiogenesis, and vascular permeability, though its possible involvement in secondary injuries after TBI is largely unknown. ...

Posttraumatic epilepsy is a frequent consequence of brain trauma, but relatively little is known about how neuronal circuits are chronically altered after closed head injury. We examined whether local recurrent excitatory synaptic connections form between dentate granule cells in mice 8-12 wk after cortical contusion injury. Mice were monitored for behavioral seizures shortly after brain injury...

introduction: application of chest radiography for all multiple trauma patients is associated with a significant increase in total costs, exposure to radiation, and overcrowding of the emergency department. ultrasound has been introduced as an alternative diagnostic tool in this regard. the aim of the present study is to compare the diagnostic accuracy of chest ultrasonography and radiography i...
