title: [Quality of buffy-coat-derived platelet concentrates prepared using automated system terumo automated centrifuge and separator integration (TACSI)].
abstract: Platelet recovery, and viability, and function is strongly dependent on the method of the preparation of platelet concentrate (PC). The glucose consumption, decrease of pH, release of alpha granules during storage in platelet concentrate impair their clinical effectiveness.
  
  
  OBJECTIVE
  To compare of the quality of buffy-coat-derieved platelet concentrates prepared using automatic system terumo automated centrifuge and separator integration (TACSI) and stored over 7 days.
  
  
  METHODS
  PCs were prepared from buffy coats using manual method (group I), or automatic system TACSI (group II). Fifteen PCs prepared from the 5 buffy coats each were stored over 7 days in 22-24 degrees C and tested. Samples were taken from the PCs container on days 1 and 7. The following laboratory tests were performed: number of platelets, platelets derived microparticles, CD62P expression, platelet adhesion, pH, glucose, lactate dehydrogenase activity.
  
  
  RESULTS
  We have observed higher expression of CD62P in PCs prepared using manual method compared to the PCs produced automatically Platelet recovery was significantly higher in PCs prepared using automatic systems compare to manual method.
  
  
  CONCLUSIONS
  Compared to manual methods, automatic system for preparation of buffy coats, is more efficient and enable production of platelets concentrates of higher quality.
