Platelet-rich plasma in rabbits: introduction of one experimental animal model

Background - Multiple uncertainties still exist about the action of the growth factors and the platelet-rich plasma on the mechanism of repair. Aim - To obtain the platelet-rich plasma in rabbits through a simplified and suitable method, creating an experimental model. Methods - Twenty-five female New Zealand rabbits without previous diseases were used. Fifteen mL of blood of each rabbit was collected and 10 mL of the collected blood were twice centrifugated. To check the effectiveness of the proposed method mechanical counting of the blood and of the final product were performed. Results - The mean platelet concentration was 687% higher than the initial peripheral blood counting. Mean initial platelet counting, platelet-rich plasma platelet counting and enriched were obtained with 95% CI and in terms of enrichment percentage there is a chance that the interval 530 to 844 be the real mean platelet enrichment. Conclusion - This simplified method permits to get an effective platelet-rich plasma to be used in trials about growth factors in mechanisms of tissue repair.
