ECENTLY DEVELOPED technics for the study of chromosomes in peripheral blood and bone marrow cells have resulted in important discoveries in the field of cytogenetics. Recognition of numerical and morphologic changes following irradiation and the identification of a characteristic defect, the Ph’ chromosome, in human chronic myelogenous leukemia ( CML) have aroused speculation on the relationshi...
Further investigations on phytochemical constituents of dichloromethane extract fromroots of Salvia lachnocalyx (S. lachnocalyx) led to the isolation and identification of eightknown diterpenoids from this plant for the first time. The chemical structures of the purifiedcompounds were elucidated using spectroscopic analyses including EI-MS, 1H and 13C NMR andby compariso...
The alpha4beta1 integrin very late activation antigen-4 (VLA-4) is an alpha4 (CD49d)/beta1 (CD29) heterodimer. It plays a key role in the adhesion of both hematopoietic progenitor cells and leukemic blast cells to bone marrow stromal cells which express the vascular cell adhesion molecule-1 (VCAM-1) or produce fibronectin. VLA-4 expression has been associated with bone-marrow minimal residual d...
Plasma and urine levels of cyclic adenosine 3',5'-monophosphate (cAMP) and of cyclic guanosine 3',5'-monophosphate (cGMP) were measured in 35 normal subjects, in 24 patients with nonneoplastic diseases (iron deficiency anemia, peptic ulcer, and cholelithiasis), and in 50 leukemic patients. The leukemic group included patients with acute lymphoblastic leukemia, acute myelogenous leukemia, chroni...
Polylactosaminoglycans were isolated from human chronic myelogenous leukemia cells and their structures were elucidated. The lactosaminoglycan saccharides were isolated by hydrazinolysis and fractionated by QAE-Sephadex. The structures of fractionated oligosaccharides were analyzed by fast atom bombardment-mass spectrometry and methylation before and after treatment with specific exoglycosidase...
Second generation tyrosine kinase inhibitors have recently been introduced as first-line treatment for chronic phase chronic myelogenous leukemia. We aimed to evaluate the efficacy and safety of 2(nd) generation tyrosine kinase inhibitors versus imatinib as first-line treatment for these patients. We carried out a systematic review and meta-analysis of randomized controlled trials comparing 2(n...
Granulocytic sarcoma (GS) is an extramedullary tumor composed of immature myeloid cells, typically occurring during the course of acute myelogenous leukemia. Non-leukemic GS, that is, GS with no evidence of overt leukemia and no previous history of leukemia, is very rare, and even more unusual is nonleukemic GS of the bile duct. We report a case of nonleukemic GS of the bile duct. The patient w...
BACKGROUND Flavopiridol is a protein-bound, cytotoxic, cyclin dependent kinase inhibitor. A phase II trial of flavopiridol followed by ara-C and mitoxantrone with flavopiridol given by 1-h bolus for adults with newly-diagnosed, poor-risk acute myelogenous leukemia yielded 67% complete remission with median disease-free survival of 13.6 months. DESIGN AND METHODS We compared bolus flavopiridol...
Chronic myelogenous leukemia (CML) is a malignant clonal disorder of hemopoietic stem cells characterized by abnormal proliferation and accumulation of immature granulocyte. Leukostasis is one of the complications of CML and is characterized by partial or total occlusion of microcirculation by aggregation of leukemic cells and thrombi leading to respiratory, ophthalmic or neurologic symptoms. W...
splenic infarction occurs due to occlusion of splenic vessels that leads to splenic tissue ischemia and necrosis. there are several reports regarding splenic infarction in patients with acute myelogenous leukemia (aml). herein, we report a case of acute promyelocytic anemia (aml-m3) who presented with abdominal pain and splenic infarction.
