The stability of red blood cell antigens and plasma coagulation factors stored in new plastic blood packs containing either citrate-phosphate-dextrose (CPD) or citrate-phosphate-dextrose-adenine (CPDA-2) was studied. The containers were made of either polyolefin (PL 732TM) plastic without a plasticizer, or polyvinyl chloride with a non-diethylhexyl(More)
To determine what effect different preparative protocols and different platelet storage bags have on in vitro release, platelet concentrates were prepared according to two different protocols (group I: 2,200 g for 3.5 min followed by 4,900 g for 5 min; group II: 1,000 g for 9 min and 3,000 g for 20 min). The storage bags used were either a standard(More)
Red cells anticoagulated with citrate-phosphate-dextrose (CPD) or a commercial preservative solution containing adenine, sodium chloride, and mannitol (ADSOL) and stored in heat-sealed segments of plastic tubing were tested for antigen stability after refrigeration at 4 degrees C for up to 56 days. Reactivity of the A, B, c, D, K, Lea, Fya, M, and P1(More)
To determine the effect of transfusing granulocyte concentrates through microaggregate blood filters, granulocytes prepared with a cell processor were passed through screen and depth microaggregate filters. Pre- and postfiltration evaluations were made of total granulocyte count, levels of muramidase, granulocyte viability, motility, phagocytosis,(More)
To determine the effect of microaggregate blood filtration on patients with compromised pulmonary function, we divided 50 patients having elective coronary bypass surgery into two groups. One group received all blood transfusions via a 170-micron standard filter (SF). The other group received blood through a 20-micron microaggregate blood filter (MF).(More)
Fibronectin, an opsonic glycoprotein, is known to bind fibrinogen and fibrin. Microaggregate debris contained in stored bank blood is composed of degenerating platelets, leukocytes, and fibrin strands. The debris ranges in size from 10 to 160 micrometers. This study examined the effect of transfusion of 2 units of stored red blood cells, containing varying(More)
To determine the degree of damage occurring during preparation and storage of platelet concentrates, the percent release of B-thromboglobulin (BTG) and percent leakage of the cytosolic protein lactic dehydrogenase was determined sequentially from phlebotomy to the end of storage for 72 h at 20-24 degrees C. The effect of storage temperature, pH, and(More)
