Adenine and Guanine Nucleotide Metabolism During Platelet Storage at 22OC
Adenine and guanine nucleotide metabolism of platelet concentrates (PCs) was studied during storage for transfusion at 22 f 2°C over a 7-day period using high-pressure liquid chromatography. There was a steady decrease in platelet adenosine triphosphate (ATP) and adenosine diphosphate (ADP), which was balanced quantitatively by an increase in plasma hypoxanthine. As expected, ammonia accumulate...
متن کاملAn Overview on Platelet-derived Microparticles in Platelet Concentrates: blood collection, method preparation and storage
Preparations of platelet concentrates (PCs) that are stored under blood bank conditions and used for transfusion purposes, appear to be enriched in platelet derived-microparticles (PMPs) with high coagulant activity that may change platelet efficacy and safety issues. High shear stress could cause shedding of PMPs from the platelet plasma membrane, platelet aggregation, and activation of the co...
متن کاملPlatelet Factor 3 Based-clotting Time Assay as a Quality Marker for Long-term Storage of Platelet Concentrates
Background: Platelets rapidly lose their qualities usually after 5 day of storage. Different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. The purpose of this study was to demonstrate if platelet factor 3 (PF3) assay could be an indicator of storage lesion and provide ...
متن کاملProteolysis of myosin during platelet storage.
Physical properties of actomyosin from either fresh or stored platelets have been compared. Actomyosin obtained from platelets after 3 days of storage contained myosin that was 60-80% degraded to myosin rod. No myosin rod was detected in fresh platelets. The platelet myosin rod is similar to the rod produced by limited proteolysis of skeletal muscle myosin.
متن کاملPlatelet storage pool deficiency in pigs.
We report a new bleeding disease--storage pool deficiency (SPD) of platelets--in pigs from the Mayo swine colony of homozygous von Willebrand's disease (vWD) and of heterozygous carriers of vWD. Levels of factor VIII, von Willebrand factor antigen (vWF:Ag), and ristocetin cofactor (RCof) were similar in the vWD carriers and SPD pigs. The latter pigs, however, had bleeding times of 15 minutes or...
