The self-oncoprotein ErbB-2 is overexpressed in a number of malignancies. The presence of endogenous anti-ErbB-2 Ab and T cell immune responses to this protein in cancer patients has made ErbB-2 an attractive target for active immunization. However, the finding that murine anti-ErbB-2 Abs can have stimulatory, inhibitory, or no effects on cancer cell growth(More)
We have evaluated the antitumor activity of a murine antibody (IgG2a) against the leukocyte antigen CD48. CD48 is expressed on T and B lymphocytes, monocytes, and a wide range of lymphoid malignancies. To assess the therapeutic potential of an anti-CD48 antibody, we established a reproducible model of human B-cell (Raji) leukemia/lymphoma in C.B17/scid(More)
The aim of this study was to develop a flow cytometric test to quantitate low levels of circulating myeloma plasma cells, and to determine the relationship of these cells with disease stage. Cells were characterized using five-parameter flow cytometric analysis with a panel of antibodies, and results were evaluated by comparison with fluorescent(More)
High resolution 31P nuclear magnetic resonance spectroscopy has been employed to study the fermentation of glucose to ethanol by Zymomonas mobilis, strain ZM4, a bacterium which uses the Entner-Doudoroff pathway. The levels of nucleoside triphosphates, sugar phosphates, UDP-sugars and Pi in intact fermenting cells have been studied with a time resolution of(More)
Progressive multifocal leucoencephalopathy (PML) is a rare disorder characterized by progressive demyelination within the brain. It is usually fatal and occurs when there are defects in cell-mediated immunity. We report a case of PML which developed following allogeneic bone marrow transplantation. It was preceded by the development of a persistent(More)
The aim of this study was to investigate the combination of fludarabine phosphate, dexamethasone, cytosine arabinoside and cis-platinum (FLUDAP) in the treatment of patients with relapsed/refractory aggressive non-Hodgkin's lymphoma (NHL). This regimen comprises: dexamethasone 100 mg/d continuous infusion (cont. inf.) d1-3; cytosine arabinoside (ara-C) 1(More)
Previous studies have shown the presence of definite changes in the bio-electric pattern of mice correlated with the onset and presence of spontaneous adenocarcinoma of the mammary gland (Burr, Smith, and Strong, 1938). It was found that the arrangement of bio-electric gradients was characteristic for each of the two strains of mice used; one being(More)
The primary objective of this study was to determine the complete remission (CR) rate achieved with the FLAG (fludarabine phosphate, cytarabine and granulocyte colony-stimulating factor) regimen in patients with relapsed or refractory acute myeloid leukaemia (AML) or de novo refractory anaemia with excess of blasts in transformation (RAEB-t).
