In a series of important studies Murphy and his colleagues demonstrated that the preparation and storage of platelet-rich plasma and platelet concentrates at 22°C rather than 4°C improved their life span in vivo (Murphy and Gardner, 1969; Murphy, Sayar, and Gardner, 1970). The potential clinical relevance of this finding has been confirmed by Handin and Valeri (1971), and it is likely that this...

S UMMA R Y. Rapid and relevant evaluation of platelet function is often clinically important. By means of fluorescent labelled chicken antibodies (which do not bind to Fc-receptors) against fibrinogen and von Willebrand factor and flow cytometry, we have determined the time course of ligand association to platelets after stimulation with adenosine 5’-diphosphate and ristocetin respectively. The...
This paper is a preliminary report of in vitro studies comparing platelet storage in the new polyolefin PL732 packs with the present polyvinyl PL146 packs. The parameters used to assess platelet viability in these studies were the recovery from the hypotonic stress test (HST) and the pH. The effect of the mass of concentrate was assessed by preparing 20 g, 35 g and 50 g packs. The method of agi...
The platelet-rich fibrin-like matrix (PRFM) is usually prepared onsite and immediately used for regenerative therapy. Nonetheless, to meet the clinical necessity of preserving the PRFM without quality deterioration, we developed a method for preparation of PRFMs from short-term-stored whole blood (WB) samples. In this study, to evaluate the practical expiration date of storage, we extended the ...
