Background and purpose: Cold storage results in clustering of gpIbα molecules on platelets. Consequently, the lectin domains of αMβ2 receptors on the liver macrophages recognize these molecules and ingest the platelets. Probably coverage of sugar molecules of gpIbα using galactose could prevent the recognition and ingestion of platelets by macrophages. The purpose of this study therby was to...
Erythropoietin reduces storage lesions and decreases apoptosis indices in blood bank red blood cells
BACKGROUND Transfusion of blood at the limits of approved storage time is associated with lower red blood cell (RBC) post-transfusion recovery and hemolysis, which increases plasma cell-free hemoglobin and iron, proposed to induce endothelial dysfunction and impair host defense. There is noted variability among donors in the intrinsic rate of storage changes and RBC post-transfusion recovery, y...
118cc-1-3-117 Full text Multicenter studies require a high degree of standardization to guarantee the demanded quality standard. One potential source of error is incorrect blood specimen collection in the different study centers, especially if different types of anticoagulants or specific inhibitors (eg cyclooxygenase inhibitors for prostaglandin determinations) are used. To avoid such problems...
INTRODUCTION Cardiac surgery using cardiopulmonary bypass in newborns, infants and small children often requires intraoperative red blood cell transfusions to prime the circuit and oxygenator and to replace blood lost during surgery. The purpose of this study was to investigate the influence of red blood cell storage time prior to transfusion on postoperative morbidity in pediatric cardiac oper...
Background: As increase of cytokines (like IL-1 , IL-6 , IL-8 and TNF- ) in platelet concentrates (PCs) during storage are involved in Febrile Non Hemolytic Transfusion Reactions (FNHTRs) after Platelet transfusion, the aim of this study was the survey of these cytokines level in PCs produced in Tehran Blood Center. Materials and Methods: This study proposed to determine if WBC reduction in P...
The use of whole-blood spots on filter paper for the detection of antibody to human immunodeficiency virus type 1 (HIV-1) was evaluated during a 20-week period under a variety of storage environments simulating the harsh tropical field conditions in Kinshasa, Zaire. During the first 6 weeks of storage, all replicates of high- and low-titer HIV-1-positive reference samples remained positive by e...
We compared results for glycohemoglobin obtained from fresh whole blood or separated erythrocyte samples with results obtained after storage. We judged the storage condition to be acceptable ("stable") if the glycohemoglobin results after storage were within the 95 confidence interval (+/- SD) of the results obtained for the specimens on the day of venipuncture. Hemolysates can validly be store...
