Twenty-four kinds of water extracts derived from 22 plants that are traditionally used for the treatment of malaria on Java Island, Indonesia, were screened for their antibabesial and antimalarial activities. Among the extracts, 8 extracts displayed strong antimalarial activity, with an inhibition range from 89.6 to 100%, and 15 showed strong antibabesial(More)
Evidence suggests that T lymphocyte-mediated inhibition of hematopoiesis in myelodysplastic syndrome (MDS) contributes to cytopenia in some patients and can be reversed by treatment with immunosuppression. We examined the T-cell repertoires of 12 patients with MDS before and after antithymocyte globulin (ATG)-based treatment by T-cell receptor Vbeta(More)
Reactivation of resolved hepatitis B virus (HBV) infection, which is known as reverse seroconversion (RS), has been reported as a rare complication of allogeneic hematopoietic stem cell transplantation. We retrospectively studied HBV serologic markers in 14 recipients with pretransplant anti-hepatitis B surface antigen antibody (anti-HBs). Progressive(More)
PURPOSE The clinical outcome for elderly patients with diffuse large B-cell lymphoma (DLBCL) has improved. However, the management of elderly patients with cancer is frequently complicated by their coexisting disorders. The aim of this study was to evaluate the correlation between comorbid medical status and clinical outcome among elderly patients with(More)
We evaluated the efficacy and toxicity of a new salvage regimen, consisting of rituximab (375 mg/m(2), day 1), ifosfamide (1500 mg/m(2) on days 3-7), etoposide (150 mg/m(2), days 3-5), cytarabine (100 mg/m(2), days 3-5) and dexamethasone (40 mg/body, days 3-5) (R-IVAD) for relapsed or refractory aggressive B-cell lymphoma. In this study, a total of 32(More)
A 22-year-old Japanese man was diagnosed with Sézary syndrome with large cell transformation. His skin lesions persisted after treatment with 7 cycles of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone), psoralen and ultraviolet light A, and total skin electron beam irradiation. He subsequently underwent allogeneic bone marrow(More)
OBJECTIVE Bacillus cereus (B. cereus) septicemia is a cause of life-threatening infection in patients with hematologic diseases. However, preventing a fatal prognosis in patients with B. cereus infection has not yet been achieved due to insufficient clinical investigations. To discover more optimal treatment strategies, we analyzed B. cereus septicemia in(More)
INTRODUCTION A combination of fractionated total body irradiation (TBI) with etoposide (VP-16) and cyclophosphamide (CY) as a preconditioning regimen (VP/CY/TBI) has been reported to be safe and effective for both adults and children undergoing allogeneic bone marrow transplantation (allo-BMT). However, the reported doses of VP-16 were different. We(More)
A 27-year-old man with advanced colon cancer that was resistant to conventional chemoradiotherapies was treated with reduced-intensity allogeneic peripheral blood stem cell transplantation (PBSCT). After obtaining complete donor-type chimerism, there was an apparent graft-versus-tumor effect accompanied by severe hepatic graft-versus-host disease (GVHD)(More)
