Platelet Count and Platelet Stickiness in Rats

Thrombosis and Haemostasis, 1971
SummaryIn 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 Aggregometry and Anti-Platelet Isoantibodies

Haemostasis, 2009
102 sera from polytransfused patients have been screened in platelet aggregometry. Anti-human platelet isoantibodies, tested against ‘responsive’ human platelets in PRP, give in the aggregometer a decrease in optical density recorded as a sigmoidal curve.

Status of Platelet Collection and Platelet Transfusion

Therapeutic Apheresis, 2001
Abstract: 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 ...

Platelet aggregation and platelet-inhibiting drugs

Neurochemical Pathology, 1987
Platelet 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 dose for prophylactic platelet transfusions

Expert Review of Hematology, 2010
Although 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 ...

Platelet Glycolysis in Platelet Storage

Transfusion, 1979
The 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.

Effects of clofibrate on platelets and evidence of the involvement of platelet lipids in platelet function

Thrombosis Research, 1977
Abstract The effects of clofibrate, a recognised plasma lipid lowering agent, on platelet function and lipid metabolism were examined to determine the role of platelet lipids in platelet function and the mechanism of the inhibitory action of clofibrate on platelets.

Platelets and platelet inhibitors in infective endocarditis

Current Infectious Disease Reports, 2002
The 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 ...

Platelet associated IgG, platelet survival, and platelet sequestration in thrombocytopenic states

British Journal of Haematology, 1982
Summary. Platelet‐associated IgG (PAIgG), platelet mean life span (MLS), and platelet sequestration sites were studied in 69 patients with immune (ITP) and presumed nonimmune thrombocytopenias (NTP). A shortened MLS was associated with elevated PAIgG (N=46), and with normal PAIgG (N=15), Four patients had a normal MLS, but elevated PAIgG, four ...

The Platelet Count and Mean Platelet Volume

British Journal of Haematology, 1981
Summary. 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.
