Platelet Microparticles: A Carrier of Platelet-Activating Factor?
Biochemical and Biophysical Research Communications, 1996Platelet-activating factor (PAF) has been considered to be released in a soluble form from activated platelets. Also a considerable number of microparticles were released from stimulated platelets. To evaluate the possibility that microparticles contain PAF, the amount of PAF in whole activated platelets, microparticles and the suspending medium was ...

Platelet Factor 3 Activity in Washed Platelets
Thrombosis and Haemostasis, 1973SummaryPlatelets collected with an EDTA solution and simply washed in an incomplete Tyrode’s presented clotting times in the recalcification (man and rat) and the Stypven (rat) tests that were practically identical to those of the PRP when slow speed centrifugation was used (800 G in man, 1000 G in rat). This was demonstrated, in 6 pools of 5 rats each

Radioimmunoassay for platelet‐activating factor
Lipids, 1991AbstractA radioimmunoassay (RIA) for measurement of platelet‐activating factor (PAF) was developed. At a final antiserum dilution of 1∶640, the lowest detection limit of PAF was 0.1 pmol (50 pg). The standard curve obtained was suitable for measurement of PAF in amounts ranging from 0.1 pmol to 30 pmol. The antiserum showed high specificity.

Platelet-activating factor receptor
Prostaglandins & Other Lipid Mediators, 2002Platelet-activating factor (PAF, 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine) is a biologically active phospholipid mediator. Although PAF was named for its potential to induce platelet aggregation, intense investigations have elucidated potent biological actions of PAF in a broad range of cell types and tissues.

Thrombin and Platelet Activation
Chest, 2003The accumulation of thrombin at sites of vascular injury provides one of the chief means for recruiting platelets into a growing hemostatic plug. Studies completed over the past 10 years show that platelet responses to thrombin are mediated by a subset of G protein-coupled receptors known as protease-activated receptors.

Cisplatin Triggers Platelet Activation
Thrombosis Research, 2000Clinical observations suggest that anticancer drugs could contribute to the thrombotic complications of malignancy in treated patients. Thrombotic microangiopathy, myocardial infarction, and cerebrovascular thrombotic events have been reported for cisplatin, a drug widely used in the treatment of many solid tumours.

Platelet-activating factor and asthma
Journal of Allergy and Clinical Immunology, 1988anaphylaxis. And if you research into the 1920s) there a very useful treatment in blocking both thrombocyare articles, particularly in the German literature, that topenia and some of the features of anaphylaxis. The report thrombocytopenia as being a feature of clinical first article (1924) stated that heparin totally prevents asthma.

Platelet Activation in Acute Pancreatitis
Pancreas, 2012The aim of this study was to assess the functional state of platelets in patients with mild acute pancreatitis and severe acute pancreatitis (S-AP).The number of platelets and their morphological parameters were measured with Advia 2120. β-Thromboglobulin and platelet factor 4 concentrations were determined by enzyme-linked immunosorbent assay method ...

Platelet Activating Factor and Platelets
1999Among agents which activate platelets PAF is unique since it is the only phospholipid known to date which stimulates platelets at nanomolar range. The first indications of such a mediator dates back to 1966 when it was observed that a mixture of rabbit platelets and stimulated leukocytes released histamine on specific antigen challenge (Barbaro and ...
