Ribonucleotide Reductase of Rabbit Bone Marrow

Ribonucleotide reductase of rabbit bone marrow.

Ribonucleotide reductase activity was increased in extracts of bone marrow from rabbits treated with methyl phenyldiazenecarboxylate, a hemolytic agent which results in an increased number of reticulocytes in blood. The enzyme has been partially purified from bone marrow of rabbits treated with this agent. Enzymatic reduction of cytosine ribonucleotides requires a dithiol, magnesium ions, and A...

MRI evaluation of rabbit bone marrow after acute irradiation

Background: Magnetic Resonance Imaging (MRI) is a safe modality and useful in characterizing normal and abnormal bone marrow (BM). MRI also presents a more global view of BM than biopsy therefore, it may provide a better understanding of hematologic disorders. The purpose of this study was to monitor radiation-induced alterations of BM in acute phase of irradiation (1-10 day after total body ir...

The Role of Bone Marrow Aspiration and Bone Marrow Biopsy in Diagnosis of Bone Marrow Metastases

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...
