This study was undertaken to examine the effect of transforming growth factor-beta 1 (TGF-beta 1) administered into the subarachnoid space after spinal cord injury (SCI) on the increased production of inducible-nitric oxide synthase (i-NOS) in the injured spinal cord in rats. The expression of i-NOS mRNA after SCI was remarkably down-regulated by TGF-beta 1(More)
The intercellular adhesion molecule 1 (ICAM-1) plays an important role in immune responses by promoting infiltration of neutrophils into tissues; however, its implication in the secondary destructive pathomechanism after the initial mechanical injury to the spinal cord has not been clarified yet. This study was conducted to examine the role of ICAM-1 in(More)
This study was undertaken to examine the spinal cord of rats after trauma for the induction of apoptosis. DNA ladder formation was demonstrated by gel electrophoresis of the DNA obtained from the spinal cord at the site of injury after trauma from 12 h to 8 days and was most significant on Days 3 and 4. As for the longitudinal spread of the injury in the(More)
OBJECTIVE In an attempt to elucidate a possible role for eicosanoids in the pathogenesis of spinal cord injury (SCI), we measured the concentration of leukotriene (LT) C4, thromboxane B2, and 6-keto-prostaglandin F1 alpha in cerebrospinal fluid in both a canine experimental model and 11 patients with SCIs. METHODS The eicosanoid concentration in(More)
Delayed CT Myelography (CTM) demonstrated intramedullary cavities in 18 patients, most of which appeared on the 6-hour scan. The attenuation values of the normal spinal cord increased progressively with time, and recorded a peak at 6 hours. The CT numbers of the gray matter of metrizamide were significantly high, as compared with those of iotrol. In the(More)
The aims of this study were to examine whether the heat shock response is operative in the spinal cord, and to identify the type of responsible cell. Immunoblot analysis using an antibody specific for a highly stress-inducible heat shock protein with a molecular mass of 72 kDa (HSP72) showed that exposing rats to whole body hyperthermia remarkably induced(More)
STUDY DESIGN Transverse areas of the spinal canal, the dural tube and the spinal cord of the cervical spine of normal adults and patients with cervical spondylotic myelopathy (CSM) were analyzed by magnetic resonance imaging (MRI). OBJECTIVES Correlations of the results of MRI to clarify the pathogenesis of CSM. SUMMARY OF BACKGROUND DATA Relationships(More)
We have reviewed 37 patients under the age of 18 years with lesions of the lumbar posterior end plate. All but one were active in sport, and most were seen because of low back pain. An abnormality was commonly found at the inferior rim of the body of L4 and at the superior rim of the sacrum. All adjacent intervertebral discs showed a decrease of signal(More)
The effects of lecithinized superoxide dismutase (PC-SOD) and/or methylpredisolone (MP) in preventing secondary pathological changes after spinal cord injury (SCI) were investigated in rats with reference to recovery of hindlimb motor function and expression of mRNA of pro-inflammatory and neurotrophic genes. Hindlimb motor function was assessed as the BBB(More)
Although superoxide dismutase (SOD) has been reported to promote functional recovery in ischemic spinal cord injury, it presents many difficulties in practical use primarily due to its short half-life in vivo and low tissue affinity. In this study, we investigated the effects of a new type of SOD, a lecithinized superoxide dismutase (PC-SOD), on motor(More)
