introduction bacillus calmette-guérin (bcg) vaccine, a live attenuated mycobacterium bovis strain, is administrated to all newborn infants in endemic regions according to the current world health organization (who) recommendation. case presentation we report a 10-month-boy who was a known case of severe combined immunodeficiency (scid) admitted with multi-focal fusiform painful swelling in his ...

Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...

Background & objective: Introduction: First detection of any solid tumour as metastatic deposits in bone marrow directs clinicians to start searching for the primary tumour. Detection of bone marrow metastasis determines the stage of the malignancy, prognosis, mode of treatment, chemotherapeutic response and follow-up in case of relapse. The aim of the current...

PURPOSE To examine the influence of α-particle radiation exposure from internally deposited plutonium on chromosome aberration frequencies in peripheral blood lymphocytes of workers from the Sellafield nuclear facility, UK. MATERIALS AND METHODS Chromosome aberration data from historical single colour fluorescence in situ hybridization (sFISH) and Giemsa banding (G-banding) analyses, together...

In order to study the normal hematopoiesis, cellular components and myeloid/erythroid (M/E) ratio in the bone marrow of the pheasant (Phasianus colchicus), bone marrow samples were collected from the proximal tibiotarsus bone of 16 clinically healthy adult pheasant. The bone marrow smears were stained using the Giemsa stain. The results indicated that the development and formation of b...

A man with acute myelogenous leukemia, treated with chemotherapy, had a decrease in circulating formed blood elements. Bone marrow biopsy revealed necrosis. Imaging with In-Ill chloride demonstrated activity in the liver, but not in the spleen or bone marrow. Eighteen days later, the circulating blood count had risen; a repeat bone marrow biopsy showed the return of blood cell precursors....

Presently, skeletal dosimetry models utilized in clinical medicine simulate electron path lengths through skeletal regions based upon distributions of linear chords measured across bone trabeculae and marrow cavities. In this work, a human thoracic vertebra has been imaged via nuclear magnetic resonance (NMR) spectroscopy yielding a three-dimensional voxelized representation of this skeletal si...

Purpose: To determine the frequency of CT procedures in a cohort of bone marrow transplant patients and estimate the effective dose from each CT procedure as well as rough estimates of lifetime attributable risk (LAR) of cancer (both incidence and mortality). Background: Pediatric patients who undergo bone marrow transplant benefit greatly from the diagnostic power of computed tomography, but d...

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...
