Hemoglobin Function in Stored Blood
INTRODUCTION The ultimate aim in transfusing blood is the maintenance or restoration of a medium for the transport of oxygen to body tissues. Most often, the efficacy of transfusion therapy is evaluated by survival of the donor erythrocytes in the recipient. However, red cells may have a normal in vivo survival yet be unable to bind and unload oxygen physiologically. In 1956, Valtis and Kennedy...
متن کاملIron accelerates hemoglobin oxidation increasing mortality in vascular diseased guinea pigs following transfusion of stored blood.
Non-transferrin-bound iron (NTBI) and free hemoglobin (Hb) accumulate in circulation following stored RBC transfusions. This study investigated transfusion, vascular disease, and mortality in guinea pigs after stored RBC transfusion alone and following cotransfusion with apo-transferrin (apo-Tf) and haptoglobin (Hp). The effects of RBC exchange transfusion dose (1, 3, and 9 units), storage peri...
متن کاملMultiphoton excited hemoglobin fluorescence and third harmonic generation for non-invasive microscopy of stored blood.
Red blood cells (RBC) in two-photon excited fluorescence (TPEF) microscopy usually appear as dark disks because of their low fluorescent signal. Here we use 15fs 800nm pulses for TPEF, 45fs 1060nm pulses for three-photon excited fluorescence, and third harmonic generation (THG) imaging. We find sufficient fluorescent signal that we attribute to hemoglobin fluorescence after comparing time and w...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولPosttransfusional recovery of defective respiratory function of stored blood in dogs.
Changes in the oxygenation properties and the relevant biochemical parameters of canine blood were followed during its storage in acid-citrate-dextrose (ACD) medium (4 degrees C) and after transfusion of the stored blood. Reductions of the blood P50 (pH 7.40, PCO2 40 Torr, 37 degrees C) and 2,3-diphosphoglycerate (DPG) during storage was much slower than in human blood. Half-decay time for DPG ...
