Methods Sixty Wistar rats were divided in two groups (meshed and unmeshed). Each group was, then, divided into two subgroups for evaluation at 30 and 90 days. Capsules were analyzed based on hematoxylin and eosin (HE) and picrosirius staining. Results The number of fibroblasts...
Platelet-concentrated and platelet poor-plasma promote different pattern on imm...
Oliveira-Filho,Marco Antonio de; Souza,Marcelo; Tabushi,Fernando Issamu; Almeida,Luís Eduardo; Figueiredo,Fernanda Pirajá; Lourenço,Elora SampaioABSTRACT Purpose Herein we evaluated the effects of platelet concentrate (PC) and platelet-poor plasma (PPP) on bone repair using noncritical defects in the calvaria of rabbits and compared them to the presence of TGF-β1 and osteocalcin on reparative sites. Methods Five noncritical defects of 8.7 mm in diameter were created on the calvaria of 15 animals. Each defect was treated differently, using autograft (ABG...
