Electrophoretic studies of red cell extracts of stored blood.
It has been shown that red cells of blood collected in acid-citrate-dextrose (ACD) undergo changes in their dimensions, osmotic fragility, permeability and metabolism during storage at 4° C (1). Information concerning the effect of storage on the physical and chemical states of soluble red cell proteins, particularly hemoglobin, is not available. Such data may be of interest in view of the mark...
متن کاملHemoglobin 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 کاملApo E genotyping from blood stored on filter paper
BACKGROUND & OBJECTIVES Dried blood spotted on to filter paper has been found suitable for a large number of studies. In tropical countries with varying temperature conditions the use of dried blood needs to be validated. We carried out this study to assess the use of blood spotted filter paper as a transport system to study genotyping of Apo E gene. METHODS Fifty five patients visiting Cardi...
متن کاملStudies on Blood Coagulation
Although calcium is essential for the formation of thrombin, it can be recovered quantitatively from formed horse thrombin without affecting its coagulating activity. Citrate also has no significant effect. As stated in the text, this does not exclude the possibility that thrombin is actually a calcium compound present in minute concentration; but confirming the results of Hammarsten, it does s...
متن کاملStudies on Blood Capillaries
The pathway by which intravenously injected ferritin molecules move from the blood plasma across the capillary wall has been investigated in the muscle of the rat diaphragm. At 2 min after administration, the ferritin molecules are evenly distributed in high concentration in the blood plasma of capillaries and occur within vesicles along the blood front of the endothelium. At the 10-min time po...
