Status of Platelet Collection and Platelet Transfusion
Therapeutic Apheresis, 2001Abstract: Platelet product derived from single donor plateletpheresis is required to reduce the risks of adverse reactions by blood transfusion. The objectives of this study are to evaluate the status of platelet collection and its efficacy by various kinds of plateletpheresis equipment and to assess the achievement of platelet transfusion by platelet ...

Mechanism and control of platelet-platelet interactions
Microvascular Research, 1972Abstract With the technique of shadow-casting of whole platelets, it has been possible to observe both the very early events produced on the platelet surface by aggregating agents and what appears to be the entire process of platelet aggregation. It has been shown that a variety of aggregating agents and conditions such as ADP, thrombin, collagen ...

Platelet aggregation and platelet-inhibiting drugs
Neurochemical Pathology, 1987Platelet function may cause a progression of central gray matter damage after cerebrospinal hemorrhage or trauma because of the thrombotic occlusion of injured vessels or a vasospasm induced by extravasated blood. It has therefore been suggested that antiplatelet drugs could limit the extent of the neurological lesions produced by a spinal trauma.

Platelet Count and Platelet Stickiness in Rats
Thrombosis and Haemostasis, 1971SummaryIn rat, a transected tail vessel proved an adequate source of blood for platelet enumeration. When suspensions of rat blood in ammonium oxalate were rotated for 1 h a significant loss of platelets was observed. This platelet reduction rate (PRR), calculated as per cent of the pre-rotation count, showed individual constancy and inter-individual ...

Platelet Activity in Washed Platelet Concentrates
Anesthesia & Analgesia, 2004Life-threatening anaphylaxis or febrile nonhemolytic transfusion reactions after transfusion of platelet concentrates (PCs) is a serious clinical problem caused by the sensitizing of recipients to plasma components, such as immunoglobulin A, or by cytokines. There is a possible indication for washing of PCs in these thrombocytopenic patients.

Platelet Glycolysis in Platelet Storage
Transfusion, 1979The metabolism of exogenous citrate by freshly collected human platelets has been investigated by measuring the disappearance of citrate from platelet suspensions and by measuring the formation of C02 and glycogen from purified radioactive citrate. These studies indicate that platelets do not have the capacity to metabolize exogenous citrate.

Platelet dose for prophylactic platelet transfusions
Expert Review of Hematology, 2010Although guidelines exist to deal with some aspects of platelet transfusion practice, many important clinical issues have not been addressed in large randomized controlled trials (RCTs). Slichter et al. conducted a RCT of prophylactic platelet transfusions to determine the effects of the dose of platelets on clinical signs of bleeding, the use of ...

The Platelet Count and Mean Platelet Volume
British Journal of Haematology, 1981Summary. The Coulter Model S‐Plus Counter provides a measure of the platelet count and the mean platelet volume (MPV). An analysis of 5000 unselected blood specimens showed an inverse relationship between the number of circulating platelets and their MPV.

Platelets in the platelet-vessel wall interaction.
Wiener klinische Wochenschrift, 1985Ultrastructural and biochemical aspects of reversible and non-reversible platelet-vessel wall interaction are presented. Special attention is directed towards the role of release products of platelets, the plasmatic coagulation factors and the prostaglandin system.

Platelets and platelet inhibitors in infective endocarditis
Current Infectious Disease Reports, 2002The pathogenesis of infective endocarditis depends on complex interactions between the causative pathogen, plasma proteins, platelets, and vascular endothelial cells. In addition to being the main target of bacteria in the initial stage of bacterial adherence to the endocardium, platelets now appear to play an important role in antimicrobial host ...
