Iron deficiency in whole blood donors.
Each year, 5 million regular donors meet almost half the transfusion needs of the United States by voluntarily giving their blood. In this issue of Transfusion, we learn how well the needs of these committed donors are being met from an analysis of enrollment data from the Retrovirus Epidemiology Donor Study-II (REDS-II) Donor Iron Status Evaluation (RISE) study of the National Heart, Lung, and...
متن کاملThe Influence of Iron Loading and Iron Chelation on the Proliferation and Telomerase Activity of Human Peripheral Blood Mononuclear Cells
Background: Iron is an essential trace element in cell proliferation. Several investigations demonstrate that iron deprivation inhibits cell proliferation. However, the impact of iron on telomerase activity of activated lymphocytes remains unexplained to date. Objective: In this study, the effect of iron on the proliferation and telomerase activity of lymphocytes stimulated by phytohemagglutini...
متن کاملMeasurement of blood and iron loss in colitis with a whole-body counter.
Estimation with a whole-body counter of the fall in total body radioactivity due to loss of parenterally administered (59)Fe has been used to measure blood loss in 17 patients with ulcerative colitis. It was shown that blood loss was related to the activity of disease as judged by sigmoidoscopic changes and less obviously to the extent of involvement of the colon. Blood losses of 50 to 150 ml p...
متن کاملIron alters red blood cell morphology.
Under physiologic conditions a small percentage ( 3%) of red blood cells (RBCs) are irreversibly trapped within the fibrin clot mesh. By contrast, in prothrombotic states such as diabetes mellitus, significantly more RBCs are tightly bound to fibrin fibers. Such interactions affect clot properties, making it more resistant to fibrinolytic degradation. This phenomenon may explain thrombolytic re...
متن کاملThe Iron Content of the Whole Blood of Normal Individuals
During t.he course of an investigation involving the determination of blood iron values in normal subjects, it became evident that t.he results were consistently higher than the figures recently reported for human blood by Murphy, Lynch, and Howard (1) and Reich and Tiedemann (2). Furt,hermore, hemoglobin values calculat,ed on the basis of their iron determinations differed considerably from va...
