Cat brain tumors were produced by stereotactical xenotransplantation of rat glioma clone F98 into the internal capsule of the left hemisphere. Two to four weeks after implantation, the tissue content of water, sodium, potassium, calcium, magnesium, serum albumin, serum immunoglobulin, and hemoglobin was measured in samples taken from the tumor, from(More)
Experimental brain tumours were produced in adult cats by stereotactic xenotransplantation of the rat glioma clone F98. Regional ATP, glucose and lactate were measured after 2-4 weeks on coronal cryostat sections by substrate-induced bioluminescence, potassium content was imaged by the histochemical sodium cobaltinitrite method, and regional pH by(More)
The effect of barbiturate treatment on post-ischemic cerebral protein biosynthesis was studied in gerbils subjected to 5 min transient occlusion of carotid arteries followed by 2 h or 48 h recirculation. Ischemia induced a remarkable decline of amino acid incorporation into brain proteins in most forebrain structures. The initial inhibition recovered to(More)
BACKGROUND AND PURPOSE Prolonged inhibition of protein synthesis precedes delayed neuronal death in the CA1 sector of the hippocampus after transient cerebral ischemia. Organic calcium antagonists have been recommended for alleviation of ischemic neuronal damage. The present study was undertaken to investigate whether these drugs improve the recovery of(More)
OBJECT The authors examined the effect of psychological and emotional status on the outcome in patients with suspected chronic discogenic low-back pain (LBP) who have undergone lumbar fusion. METHODS The authors retrospectively analyzed the medical records, including the results of the 36-item Short Form (SF-36), of 57 consecutive patients (mean age 42.7(More)
We investigated the additive effect of repetitive transcranial magnetic stimulation (rTMS) combined with granulocyte-colony stimulating factor (G-CSF) on functional outcome in the early subacute phase of stroke. Seven-week-old male rats were subjected to permanent middle cerebral artery occlusion (MCAo) and were divided into four groups: normal saline(More)
OBJECTIVE To investigate the effect of repetitive magnetic stimulation (rMS) of the spinal cord on limb angiogenesis in healthy rats and explore its implication for the treatment of lymphedema. METHOD Twelve adult male Sprague-Dawley rats were divided into four groups as follows: sham rMS followed by tissue harvest 5 minutes later (group 1, n=2), 1 Hz rMS(More)
In adult cats experimental brain tumours were produced by stereotactical xenotransplantation of the rat glioma clone F 98 into the internal capsule of the left hemisphere. Two to four weeks after transplantation tumours and peritumoural oedema were investigated by magnetic resonance imaging (MRI), electrophysiological recording and analysis of tissue(More)
Focal cerebral ischemia was produced in monkeys by injection of autologous clots into the left internal carotid artery. Regional protein synthesis was studied 2 hours after embolism by autoradiographic and biochemical evaluation of [3H]phenylalanine incorporation into brain proteins, and the results were correlated with electrophysiologic(More)
