The goldfish optic nerve can regenerate after injury. To understand the molecular mechanism of optic nerve regrowth, we identified genes whose expression is specifically up-regulated during the early stage of optic nerve regeneration. A cDNA library constructed from goldfish retina 5 days after transection was screened by differential hybridization with(More)
OBJECT Postoperative C-5 palsy is a significant complication resulting from cervical decompression procedures. Moreover, when cervical degenerative diseases are treated with a combination of decompression and posterior instrumented fusion, patients are at increased risk for C-5 palsy. However, the clinical and radiological features of this condition remain(More)
Five unusual cases with massive haematoma of the corpus callosum caused by blunt head trauma are presented. Aside from the callosal haematomas, intraventricular and subarachnoid haemorrhages or small haemorrhagic foci in the basal ganglia or thalamus were common concomitant lesions on the computerized tomographic (CT) scan. The sites of the impacts were the(More)
OBJECT The cervical pedicle screw (PS) provides strong stabilization but poses a potential risk to the neurovascular system, which may be catastrophic. In particular, vertebrae with degenerative changes complicate the process of screw insertion, and PS misplacement and subsequent complications are more frequent. The purpose of this study was to evaluate the(More)
Spinal cord injury (SCI) is a devastating event resulting in permanent loss of neurological function. To date, effective therapies for SCI have not been established. With recent progress in neurobiology, however, there is hope that drug administration could improve outcomes after SCI. Riluzole is a benzothiazole anticonvulsant with neuroprotective effects.(More)
The discharges of 22 antidromically identified dorsal spinocerebellar tract (DSCT) neurones, whose activity was modulated in phase with the spontaneous respiratory cycle, were recorded in the lower thoracic segments of anaesthetized cats. Out of them, 16 neurones increased in their firing rate during the inspiratory phase and 6 during the expiratory phase.(More)
OBJECTIVE To report a series of four cases of intradural disc herniation (IDH) with a review of the literature. SUMMARY OF BACKGROUND DATA IDH is a rare type of disc herniation. Preoperative diagnosis is difficult and IDH is only confirmed during surgery in most cases. Here, we describe four cases of IDH, including three with lumbar hernia and one with(More)
OBJECT Cervical spondylosis that causes upper-extremity muscle atrophy without gait disturbance is called cervical spondylotic amyotrophy (CSA). The distal type of CSA is characterized by weakness of the hand muscles. In this retrospective analysis, the authors describe the clinical features of the distal type of CSA and evaluate the results of surgical(More)
