a 25-year old man presented with chronic low back pain for about 5 years due to mild congenital lumbar kyphosis (l1-l3 25° with congenital posterior wedge vertebra l2). preoperative neurologic examination was normal. after posterior spinal fusion and instrumentation with moderate curve correction, the patient gradually developed the symptoms and signs of cauda equina syndrome due to intraoperat...

objective: recent studies have shown that the use of prolonged and intermittent normobaric hyperoxia (95%) decrease the infarct volume of stroke. the aim of current study was to study the effect of an oxygen radicals-scavenger applied during intermittent normobaric hyperoxia on infarct volume in the rat brain and neurologic deficit. materials and methods: male wistar rats (250-350 g) were divi...
