Alterations in local cerebral glucose utilization (LCGU) induced by electrical stimulation of the sensory relay nucleus (VPL) or parafascicular nucleus (Pf) of the thalamus in conscious rats were measured by the [14C]2-deoxyglucose method, the objective being to assess the mechanism of analgesia induced by electrical stimulations of these structures.(More)
BACKGROUNDS Chemotherapy is a mainstay in the treatment of extensive-disease small-cell lung cancer (ED-SCLC), although the survival benefit remains modest. We conducted a phase II trial of amrubicin (a topoisomerase II inhibitor) and topotecan (a topoisomerase I inhibitor) in chemotherapy-naïve and relapsed SCLC patients. METHODS Amrubicin (35 mg/m(2))(More)
In a patient with a syndrome of continuous muscle fiber activity, peripheral nerve block completely abolished the EMG discharges. Reduction of spontaneous discharges by epidural block and demonstration of a silent period after the H response suggested that the disorder may originate in the spinal cord or ventral roots, sparing inhibitory influences on the(More)
It has been reported that the F-Dopa (FD) uptake in patients with idiopathic Parkinson's disease (PD) decreased significantly in the caudate and putamen when compared to controls. The FD uptake severely decreased in the putamen, while it was relatively spared in the caudate nucleus. We also previously reported that atypical parkinsonism with no or little(More)
Alterations in local cerebral glucose utilization (LCGU) in rats with unilateral striatal lesions and the modification by apomorphine were investigated. Electrolytic lesions were made in the rostral part of the right striatum, and 1, 7, and 30 days later, LCGU was observed in terms of relative and absolute LCGU values, using the [14C]deoxyglucose method. A(More)
Positron emission tomographic (PET) studies of regional cerebral glucose metabolism were performed in patients with various types of dementia, patients with Parkinson's disease but without dementia, and healthy normal controls. Patients with Alzheimer-type dementia showed significant decreases in glucose metabolism in frontal, temporal, parietal,(More)
A patient with a right internal capsule and thalamic hemorrhage showed ipsilateral hemiplegia. MRI at 10 months after the cerebral hemorrhage demonstrated Wallerian degeneration, which could be traced to the ipsilateral anterior funiculus at the cervical level. The findings of motor evoked potentials and somatosensory evoked potentials indicate a(More)
Striatal blood flow, glucose metabolism and 18F-Dopa uptake were studied with positron emission tomography (PET) in eight non-demented patients with idiopathic Parkinson's disease and eight with atypical Parkinsonism. Patients with atypical Parkinsonism had no specific cause for the Parkinsonian symptoms and were clinically different from Parkinson's(More)
Alterations in local cerebral glucose utilization (LCGU) in conscious rats during electrical stimulation of the striatum and the globus pallidus were investigated using the [14C]deoxyglucose method. Stimulation of the globus pallidus produced a marked contraversive circling behavior, while stimulation of the striatum led only to contraversive head turning.(More)
Alterations in local cerebral glucose utilization (LCGU) following ablations of the unilateral frontal cortex in rats were studied to elucidate the effect of the lesion on the functional activity in the related cerebral structures. Frontal cortical ablations (areas 2, 4, 6 and 10) were made by aspiration on the left side, and LCGU was evaluated at 7 days(More)
