We compared fMRI findings (using SPM99) obtained with repetition task in normal subjects with those of two patients with Broca's and Wernicke's aphasia who received speech therapy and showed complete recovery. Both aphasic patients with left hemisphere damage who showed complete recovery exhibited activation of only the compensatory area in the right(More)
Our present study shows that transient changes in relative cerebral blood volume (rCBV) induced by stimulation with bicuculline under six different conditions of anesthesia can be detected with high spatial resolution functional magnetic resonance imaging (fMRI). Bicuculline was administered at a low dose to induce neural activation, and no seizure activity(More)
A new model useful for studying capillary growth in vitro is described. When the microvessel fragments and accompanying single cells (myofibroblastic cells) from rat epididymal fat pads were co-cultivated, the myofibroblastic cells initially began to grow and reached confluence. A few days later, endothelial cells started to sprout from the vessel(More)
Glomerular visceral epithelial cells (vGEC) play an important role in the synthesis of the glomerular basement membrane (GBM), and together with glomerular endothelial cells and the GBM, in glomerular ultrafiltration. Therefore clarification of the properties of vGEC is essential to investigations of glomerular morphology and function in both physiologic(More)
A serial section study of leukaemic lymphocytes was carried out to elucidate the three dimensional morphology of nuclear pockets containing nuclear material and their mode of genesis. From this and a previous study on nuclear pockets containing cytoplasmic material we conclude that these are two distinct lesions each with its own mode of genesis and one(More)
A serial section study of nuclear pockets in a lymphoma of the stomach showed that: 1) no tumour cell nucleus was free of pockets; 2) approximately 10 to 50 pockets occur on a nucleus; and 3) the pockets show a focal rather than a diffuse distribution on the nucleus. In most pockets cytoplasmic material is completely sequestrated and no channel of(More)
Two cell lines, T24 and MGH-U1, established from human urinary bladder carcinoma showed typically epithelial features. Although the proliferating cell population presented a polymorphic appearance including polygonal and elongated cells, ultrastructural studies failed to identify different types of cells in each cell line. Extensive cytoplasmic organelles,(More)
The follicular dendritic cells (FDC) in B-lymphoid follicles are unique reticular cells that retain immune complexes on their surfaces. We developed new monoclonal antibodies (MAb), SKY01, 28, 41, and 49, against mouse FDC without useful cell markers. Immunohistochemical study of spleen and lymph node tissues from Balb/c, C3H, and C57BL/6 mice revealed that(More)
Background: Recently, functional MRI (fMRI) is used for the judgment of the training effect of the aphasia. However, this task is very difficult for fMRI. The purpose of this study is to evaluate fMRI repetition data using block design and event-related design. Subjects and Methods: Eleven healthy control men (mean±s.d. 20.4±1.55 years) participated in this(More)
