BACKGROUND Prophylactic transplantation of marrow stromal cells (MSCs) before spinal cord ischemia has been shown to attenuate neurologic injures. We sought to investigate the therapeutic effect of MSCs on ischemia-injured spinal cord. METHODS Marrow stromal cells were expanded in vitro and prelabeled with bromodeoxyuridine. Spinal cord ischemia was(More)
BACKGROUND It has been shown that transplantation of bone marrow stromal cells (MSCs) into the ischemic brain improves functional outcome. We sought to investigate whether intrathecal injection of MSCs can attenuate neurologic injury of spinal cord ischemia. METHODS Rabbit MSCs were expanded in vitro and were pre-labeled with bromodeoxyuridine. Spinal(More)
OBJECTIVE We investigated the neuroprotective effect of NS-7 (4-[4-fluorophenyl]-2-methyl-6- [5-piperidinopntyloxy] pyrimidine hydrochloride), a novel Na(+)/Ca(2+) channel blocker, on transient spinal cord ischemia in rabbits. METHODS Spinal cord ischemia was induced in New Zealand white rabbits by means of infrarenal aortic occlusion for 20 minutes. Four(More)
OBJECTIVES Arterial variation is common in the vertebral artery, and simple occlusion of the left subclavian artery may result in brain infarction, especially when it terminates in the posterior inferior cerebellar artery (PICA). We report the results of preoperative vertebral artery evaluation by magnetic resonance angiography (MRA) and its impact upon(More)
A 62-year-old man presented with repeated embolic infarction over the last 3 years. Computed tomography angiography of the aortic arch revealed that the patient had a common trunk for the innominate and left carotid arteries, the so-called bovine aortic arch, with stenosis extending to both the left common carotid artery and innominate artery. Since(More)
