Purpose Herein we evaluated the effects of platelet concentrate (PC) and platelet-poor plasma (PPP) on bone repair using noncritical defects in calvaria rabbits compared them to presence TGF-β1 osteocalcin reparative sites. Methods Five 8.7 mm diameter were created 15 animals. Each defect was treated differently, autograft (ABG), ABG associated with PC (ABG + PC), PPP PPP), isolated PPP, blood ...
A method is presented for isolating osteoblasts from newborn mouse calvaria without the use of digestive enzymes. The procedure is based on the ability of osteoblasts to migrate from bone onto small glass fragments (Jones, S.J., and A. Boyde, 1977, Cell Tissue Res., 184:179-193). The isolated cells were cultured for up to 14 d in Dulbecco's modified Eagle's medium supplemented with 10% fetal ca...
Objective: To determine the regenerating effect of hyaluronic acid on circumferential bone defects in albino Wistar rats. Material and Methods: An experimental type study was designed carried out with 15 male rats, 4 months old weighing between 250 350 grams. Two 3mm diameter 0.8mm deep were created calvaria parietal (on both sides midline). One defect filled a demineralized matrix (control gro...
Introduction: The establishment of new therapeutic approaches for tissue repair and regeneration can be accelerated if adequate technologies for monitoring the repair process are developed. In craniomaxillofacial surgery, 96,000 bone graft procedures are performed each year to treat bone loss due to trauma or disease. Alas, autologous bone grafts are not always available, and additional surgery...
Gentamicin was evaluated for developmental toxicity in pregnant Sprague-Dawley rat. Gentamicin was administered subcutaneously on days 6-15 gestation at dose of 100 mg/kg. On gestation day 21, all live fetuses were examined for external and skeletal malformations and variations. Increased resorptions and dead fetuses, and reduced fetal body weight were observed at dose of 100 mg/kg. Gentamicin ...
