Curasan PRP kit vs. PCCS PRP system

2002

An important reason to improve methods of isolating platelet-rich plasma (PRP) is the potential use of autologous thrombocyte growth factors. In addition to discontinuous cell separation, two methods for extracting PRP that can be performed directly by the surgeon are now available. This study compared the suitability of these two methods for the preparation of PRP. Whole blood was drawn from 47 healthy donors (18 men, 29 women) aged 20-59 years (mean 29.9, SD 7.7). For each donor, PRP was separated by the PCCS method (PCCS Kit, 3i Implant Innovations, Palm Beach Gardens, FL, USA) and by the Curasan method (analogous to the PRP kit, Curasan, Kleinostheim, Germany). Thrombocyte counts differ…

Growth factor levels in platelet-rich plasma and correlations with donor age, sex, and platelet count.

2002

Abstract Introduction: Platelet-rich plasma contains autologous thrombocyte growth factors and might be promising for acceleration of dentoalveolar bone regeneration. In this study, it was analysed for platelet counts and growth factor concentrations. Material and method: Platelet-rich plasma was isolated by discontinuous cell separation from 158 healthy men and 55 women aged 17–62 years. One hundred and fifteen specimens (stratified for age and gender of the donor) were analysed for growth factor concentrations and platelet count. Results: The platelet count in platelet-rich plasma (1,407,640±320,100/μl) was 5 times higher than in donor blood (266,040±60,530/μl). Platelet-derived growth fa…
