The aim of this study was to characterise brain tumour type and treatment response in relation to the uptake of thallium-201.201Tl single photon emission tomography (SPET) was performed in 58 patients with brain tumours. Fifty-six patients were utilised for the statistical comparison of the early and delayed201Tl indices expressed as the ratio of tumour to(More)
BACKGROUND Nobody knows whether cognitive dysfunction affects survival. Furthermore, it is unknown whether the dysfunction is caused by the tumor itself or by its treatment. METHODS Patients with 20 gliomas (LGG, 7; MG, 13 [AG, 4; GM, 9]) in the right brain (nondominant) and 11 gliomas (LGG, 1; MG, 10 [AG, 6; GM, 4]) in the left brain (dominant) were(More)
Brain metastases from gynecological cancers were retrospectively investigated in 18 patients who were treated between 1985 and 2006. Six patients received surgical resection followed by radiotherapy, and 12 patients received only radiotherapy. The median survival for all patients was 4.1 months (range 0.7-48.2 months), and the actuarial survival rates were(More)
We present a rare case showing symptomatic vasospasm after intraventricular hemorrhage from a ruptured arteriovenous malformation. No significant subarachnoid hemorrhage in the basal cisterns was observed on computed tomography in the entire course of illness. Although most cases showing vasospasm are associated with the deposition of blood in the basal(More)
We previously reported that the anti-inflammatory cytokine interleukin (IL)-4 induced selective clearance of oligomeric β-amyloid (Aβ(1-42)) in rat primary type 2 microglial cells. For the present study, we investigated whether IL-4 and IL-13 could activate microglial cells to induce Aβ clearance in vivo and improve cognitive deficits in APP23 mice, which(More)
A 48-year-old female presented with vertiginous feeling and behavior disturbance. Computed tomography showed an arachnoid cyst on the left cerebral convexity. Single photon emission computed tomography revealed decreased cerebral blood flow (CBF) in the left frontal lobe. The Wechsler Memory Scale-Revised test demonstrated memory dysfunction. The arachnoid(More)
Okinawa Habu (Trimeresurus flavoviridis) venom is well known for its toxic efficacy, from which one kind of specific protein, Okinawa Habu apoxin protein-1 (OHAP-1) has been extracted. The purpose of this study was to investigate whether OHAP-1 could induce apoptosis in some glioma cells, and if so, to elucidate the possible mechanism involved. Three(More)
PURPOSE To analyze retrospectively the risk factors of spinal recurrence in patients with intracranial germinoma and clinical outcomes of patients who developed spinal recurrence. METHODS AND MATERIALS Between 1980 and 2007, 165 patients with no evidence of spinal metastases at diagnosis were treated with cranial radiotherapy without spinal irradiation.(More)
Moyamoya disease is a progressive occlusive cerebrovascular disorder of unknown etiology. We describe a case of a fatal cerebral infarction after intraventricular hemorrhage in a 29-year-old primipara with moyamoya disease. The patient had been stable for about 10 days after the initial hemorrhage, but she showed a fulminant clinical course of cerebral(More)
