Platelet Disintegration during Clotting
Sequential alterations in the ultrastructure of blood platelets observed during the clotting of human platelet-rich plasma are described, with emphasis on disintegration of the platelet. As the clotting reaction proceeds, aliquots of citrated and recalcified citrated plasma are fixed by adding buffered OsO(4). After recalcification a lag period of about 10 minutes is followed by an interval of ...
متن کاملPlatelet-Rich Plasma During Clotting
detected. Ii both cases malonic acid was by far the most abundant product. The traces of glutaric and adipic acid in the oxidation products of the C18 and C1,9 acid respectively, can be explained by the presence of C20 and C21 pentaenoic acid, from which the above dicarboxylic acids are the known oxidation products. However, the possible presence of small amounts of an isomeric octadecatetraeno...
متن کاملFlow Cytometric Measurement of CD41/CD61 and CD42b Platelet Receptors and Clotting Assay of Platelet Factor 3 During Long Term-Storage of Platelet Concentrates
Background: The purpose of the present in vitro study was to evaluate the effect of long term storage of conventional platelet concentrates (PCs) on major platelet receptors CD42b and CD41/CD61 by flow cytometry method and also measuring the overall platelet procoagulant activity status using platelet factor 3 (PF3) assay. Materials and Methods: Six random units of conventional platelet conce...
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 کاملNictemeral Profile of Platelet Aggregation and Clotting Parameters in Horses during Training
The daily rhythm of platelet aggregation and clotting parameters during training were investigated in six Thoroughbred horses. Blood samples were collected every 4 h for 48 h. Platelet aggregation was measured with an aggregometer and subsequently according to the trends recorded, the percentage of aggregation was calculated. Prothrombin time (PT), activated partial thromboplastin time, thrombi...
