Background: Pancytopenia is a manifestation of a wide range of disorders. The main prognostic factor for predicting outcome and response to treatment is based on the underlying cause. To detect the root cause of this problem, depending on other accompanied signs or symptoms, the need for bone marrow examination and other advanced work ups is different at least at the practical level. This study...

Background: Previous studies about the relationship between bone marrow megakaryocyte count and the chronicity of ITP has yielded paradoxical results. The aim of the present study was to investigate any relationship between the megakaryocyte count in the bone marrow and the chronicity of ITP. Materials and Methods: This study was performed to compare the primary bone marrow aspiration megakar...

  Background and Objectives: Bone marrow necrosis (BMN) is a rare and ominous complication of wide variety of diseases including hematologic malignancy. This study was performed to identify frequency and the underlying associated diseases of marrow necrosis. Materials and Methods: In this descriptive study, totally 850 bone marrow trephine biopsies related to living patients at the Pathology ...

Recent studies of the involvement of the bone marrow in human atopic asthmatic responses to inhaled allergen confirm what we have found in a canine model of Ascaris suum induced bronchial hyperresponsiveness: CD34/45+ haemopoietic progenitors, increased in numbers in the blood and marrow of atopic individuals, can be specifically upregulated following airway allergen challenge eliciting bronchi...

hematopoietic stem/progenitor cells (hspcs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. interacting factors such as stromal derived factor-1/cxcr4, very late antigen-4/vascular cell adhesion molecule-1, lymphocyte function-associated antigen-1/ intercellular adhesion molec...

conclusions the results of this study showed that the meticulous microsurgical nerve repair, which was performed using the vein tubulization induced significantly better sciatic nerve regeneration. however, the addition of bone marrow mesenchymal stem cell to vein conduit failed to promote any significant changes in regeneration outcome. results all animals tolerated the surgical procedures and...

background: the purpose of this study was to find the accurate absorbed dose in the femur bone marrow during the x-ray radiography for constant mas and aec techniques. materials and methods: the dosxyznrc was used to simulate radiation doses in two human femurs during diagnostic radiography. egsnrc phantoms produced from actual ct images of human femurs were modified by adding seven micrometre ...

introduction: it is an unfamiliar, frightening and stressful experience for the parents of a child who is undergoing bone marrow transplantation. it is impossible to propose an effective caring method without considering all dimensions related to such experience. objective: the purpose of this study was to describe and understand the lived experiences of parents whose children were undergoing b...

background: chronic graft versus host disease (cgvhd) is one of the most serious potential complications of allogeneic bone marrow transplantation. study design and method: we analyzed the incidence of cgvhd and its associated risk factors in a group of 161 iranian recipients of hla-identical sibling transplants, with at least 90 days post-transplantation survival. in the majority of cases (n=7...
