eighteen patients, twelve men and six women, with aplastic anemia underwent allogenic bone marrow transplantation (bmt) from hla-matched siblings during the period of 1990 to 1996. the conditioning regimen was cyclophosphamide with or without busulfan, depending on the cause of aplasia. antilymphocyte globulin (alg) and cyclosporine were used for rejection and acute gvhd prophylaxis, respective...

acute myeloid leukemia (aml-m7) is a type of pediatric aml accounting for 3–10% of primary childhood aml and children may present with a broad variety of symptoms including low-grade fever, diarrhea, easy bruising, failure to gain weight and life-threatening conditions. we report a rare case of aml .a 26-month-old boy who presented with weakness and fatigue. he was diagnosed as a case of amlm-7...

background: anti-hla-antibodies are known to affect the allograft survival in transplant recipient patients. objective: the aim of this study was to evaluate the association between anti-hla antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (dbmi). methods: between june 2006 and may 2007, forty living unrelated donor kidney tra...

The morphology of the bone marrow of 21 dentists who habitually used nitrous oxide in their surgeries was investigated. Exposure to nitrous oxide was measured with an atmospheric sampling device, and each dentist was invited to fill in a questionnaire giving details of medical history, diet, and intake of alcohol. During the trial a full neurological and haematological investigation was carried...

Cisplatin is the most effective and widely used chemotherapeutic agent for many types of cancer. Unfortunately, its clinical use is limited by its adverse effects, notably bone marrow suppression leading to abnormal hematopoiesis. We previously revealed that neuropeptide Y (NPY) is responsible for the maintenance of hematopoietic stem cell (HSC) function by protecting the sympathetic nervous sy...

Intravenous (IV) injection of 0.1 to 10 micrograms of authentic prostaglandin E2 (PGE2) in intact steady-state mice induces a population of bone marrow and spleen cells having the capacity to suppress CFU-GM proliferation when admixed with normal bone marrow cells. Equivalent suppression of CFU-GM committed to monocytic as well as granulocytic differentiation was observed using colony-stimulati...

objective(s):sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. this study was performed   to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rbmmsc) into osteogenic lineage. materials and methods: isolated rbmmsc were grown in dmem supplemented with 10% fbs. the cells were exposed to different concen...

background: langerhans' cell histiocytosis (lch) is a reactive proliferative disease of unknown pathogenesis characterized by proliferation of langerhans cells. involvement of bone marrow (bm), liver and lung are related to high risk factors and poor survival. the aim of this report is to highlight the clinical and haematological findings of 5 cases of lch with bm infiltration which may help to...
