We describe a 19-year-old woman with hemophagocytic syndrome and adult Still's disease who showed rare features of central neurological involvement, including cerebellar symptoms and the sudden onset of unconsciousness with pleocytosis in the cerebrospinal fluid during the early course of the illness. As this patient's serum showed a high level of(More)
We have identified a novel RING-B-box-coiled-coil (RBCC) protein (MAIR for macrophage-derived apoptosis-inducing RBCC protein) that consists of an N-terminal RING finger, followed by a B-box zinc finger, a coiled-coil domain, and a B30.2 domain. MAIR mRNA was expressed widely in mouse tissues and was induced by macrophage colony-stimulating factor in murine(More)
More than 20 different partner genes with MLL have been cloned from leukemia cells with translocations involving chromosome 11 band q23 (11q23). All reported partner genes fused in-frame to MLL and the fusion cDNA encode chimeric MLL proteins with a significant portion derived from the partner genes. We analyzed one patient with de novo acute monoblastic(More)
Interleukin (IL)-4, IL-10, and IL-13 affect monocyte/macrophage functions including regulation of cytokine production. We analyzed the regulatory effects of these cytokines on cytokine production using a human monoblastic cell line, UG3. It is interesting that IL-10 up-regulated, whereas IL-4 and IL-13 down-regulated monocyte chemoattractant protein-1(More)
BACKGROUND Insulin signaling comprises 2 major cascades: the insulin receptor substrate/phosphatidylinositol 3'-kinase/protein kinase B and Ras/Raf/mitogen-activated protein kinase/kinase/ERK pathways. While many studies on the tissue-specific effects of the insulin receptor substrate/phosphatidylinositol 3' -kinase/protein kinase B pathway have been(More)
Differentiation inhibitory factor nm23 gene has been found to be expressed in high quantities in acute myelogenous leukemia (AML), especially in acute monocytic leukemia (AML-M5) and is suggested as a new prognostic factor in AML-M5. We report an example of elevated expression of nm23 mRNA in a patient with chronic myelogenous leukemia (CML) who developed(More)
We describe a patient with myelodysplastic syndrome (MDS) that transformed to Burkitt's acute lymphoblastic leukaemia (ALL). The leukaemic blasts were negative for peroxidase staining, and expressed CD10, CD19, CD22, CD38, human leucocyte antigen (HLA)-DR and surface immunoglobulin (sIg) M, but neither sIgD nor sIgG were expressed. Chromosomal study during(More)
A 48-year-old patient was admitted to our hospital for leukocytosis. The blast cells were positive for peroxidase and he was tentatively diagnosed as acute myeloid leukemia according to the French-American-British criteria. By flow cytometry, the bone marrow cells were positive for CD10, CD13, CD33 and HLA-DR, but two-color analysis revealed that most of(More)
Spatial disorientation (SD) is one of the most severe causative factors in aviation accidents. We analyzed the reported SD episodes to evaluate the characteristics of severe SD in fighter pilots. Three hundred seventeen cases (95.5%) of 332 total valid cases experienced SD, and the ratio of night and day SD experiences (52.7% vs. 47.3%) (p < 0.05) shows a(More)
A 69-year-old man was admitted to our hospital due to pancytopenia and a marked bleeding tendency. On admission, he had a white cell count of 2.8 x 10(9)/l, hemoglobin level of 6.0 g/dl, and a platelet count of 3 x 10(9)/l. He was given a diagnosis of refractory anemia on the basis of bone marrow aspiration findings, which disclosed trilineage(More)
