PURPOSE The aim of this report was to indicate both the advantages and disadvantages of local cell transfer therapy using ex vivo expanded autologous tumor-specific T lymphocytes (ATTLs) for recurrent cases of malignant gliomas. EXPERIMENTAL DESIGN Subjects are 10 cases of malignant gliomas consisting of 7 cases of glioblastoma multiforme, 2 cases of(More)
Autologous cytotoxic T lymphocytes (CTL) against primary-cultured malignant gliomas were generated from peripheral blood mononuclear cells in vitro in 4 patients. Activities of the CTL were highly specific to the corresponding autologous glioma and were inhibited, in one patient, with antibodies against CD3, CD8 and MHC-class I molecules. When the CTL were(More)
The authors induced autologous cytotoxic T lymphocytes (CTLs) directly from peripheral blood lymphocytes by preparing a coculture of minced tissue fragments of glioblastoma multiforme (GBM) with interleukins-1, -2, -4, and -6 and interferon-gamma in RHAM alpha medium containing 5% autologous plasma for 2 weeks. At the end of this period, the frequencies of(More)
Fifteen patients with clinical diagnosis of brain death were examined by magnetic resonance (MR) imaging. Aortography with intraarterial digital subtraction angiography (IADSA) was also performed in nine patients. MR imaging indications of the flow void phenomenon were evaluated in the cavernous portion of internal carotid artery (ICA) and the middle or(More)
Complications associated with intraarterial papaverine infusion occurred in two patients treated for vasospasm due to subarachnoid hemorrhage (SAH). A 42-year-old male with an anterior communicating artery aneurysm underwent craniotomy and aneurysm clipping. Five days after the SAH occurred, angiography demonstrated moderate vasospasm in spite of(More)
Intracranial hemangioblastomas (HBs) are hypervascular neoplasms mainly located in the posterior fossa of the central nervous system. Preoperative embolization of the feeding arteries is one proposal for reduction of intraoperative hemorrhage, although indications for the procedures should be evaluated carefully due to the potential complications. This(More)
Surface-mediated gene transfer systems using apatite (Ap)-based composite layers have received increased attention in tissue engineering applications owing to their safety, biocompatibility and relatively high efficiency. In this study, DNA-antibody-apatite composite layers (DA-Ap layers), in which DNA and antibody molecules are immobilized within a matrix(More)
A 3-year-old girl with spinal cord injury without radiologic abnormality (SCIWORA) is reported. Magnetic resonance imaging (MRI) showed an abnormal intensity of the spinal cord at the level of C7 to Th1 in the acute stage and severe atrophic change in the chronic stage. This is the first report of SCIWORA with positive diagnostic imaging. The mechanism of(More)
Our objective was to develop a bone substitute coated with fibroblast growth factor-2 (FGF-2) that subsequently releases FGF-2. We investigated the use of our system of bone substitutes to induce bone formation. Hydroxyapatite ceramic buttons (HAP-CBs) were coated with FGF-2 by precipitation in supersaturated calcium phosphate solution. HAP-CBs were coated(More)
BACKGROUND We have recently developed a safe and efficient gene transfer system using a laminin-DNA-apatite composite layer. The objectives of the present study were to fully characterize and optimize the laminin-DNA-apatite composite layer in relation to the efficiency of gene transfer and to demonstrate the feasibility of the composite layer in the(More)
