13. Experimental model of distraction osteogenesis in edentulous rats
Distraction osteogenesis (DO) is a surgical technique producing bone lengthening by distraction of the fracture callus. Although a large number of experimental studies on the events associated with DO of craniofacial skeleton have been reported, the few employing rat mandibular bone DO used complicated designs and produced a small volume of newly formed bone

15. Efeitos do carbonato de lodenafila na consolidaÃÃo de fraturas da diÃfise femoral de Ratos tratados com haste intramedular / Effects of lodenafil carbonate on femoral diaphysis fractures healing in rats treated with intramedullary stem.
The study was to investigate the effects of Lodenafil Carbonate in the process of bone healing in femurs of rats with reduced KirshnerÂs wire. The vascular factors are extremely important for the formation of callus. Lodenafil Carbonate cause vasodilatory effects, belongs to the group of selective phosphodiesterase type 5(PDE5) inhibitors, that enzyme inhib

16. OSTEOSSÍNTESE UMERAL EM POMBOS DOMÉSTICOS (Columba lívia) POR XENOENXERTO ÓSSEO, CONSERVADO EM MEL TRATADOS OU NÃO COM LASER ARSENETO DE GÁLIO (AsGa) / OSTEOSYNTHESIS OF THE HUMERAL IN DOMESTIC PIGEONS (Columba lívia) BY BONE XENOGRAFTS, PRESERVED IN HONEY TREATED OR NOT WITH GALLIUM ARSENIDE LASER (GaAS)
The increase in attendance of wild animals, especially birds, leads to the veterinarian deal with numerous diseases in these animals, being the fractures one of the most frequent injuries in the veterinary clinical surgery. The aim of this study was to reduce the recovery period of birds with humeral fracture in order to anticipate the release of them back i

17. Avaliação da reparação e indicadores de desnutrição de ratos submetidos à fratura de côndilo mandibular e com desnutrição protéica / Evaluation of healing and undernutrition indicatives of rats submitted to mandibular condyle fracture and with protein undernutrition
This study evaluated the healing and undernutrition indicatives of rats submitted to mandibular condyle fracture and with protein undernutrition (8% of protein with vitamin and minerals supplement). Forty-five adult male Wistar Rattus norvegicus were used and distributed in 3 groups of 15 animals: fracture group, submitted to condylar fracture with no change

18. Alloxan-induced diabetes delays repair in a rat model of closed tibial fracture
A closed fracture was performed on the left tibia of 3-month-old Wistar rats weighing 250 to 350 g that were either healthy (N = 24) or made diabetic with alloxan (N = 24) to investigate the effect of alloxan-induced diabetes on the course of bone fracture healing. Histomorphometric analysis of the fracture site was performed at 7, 14, 25, and 35 days. After

19. Influence of methotrexate on bone healing of a defect simulating a fracture in rat mandible / Avaliação do efeito do metotrexato na reparação tecidual em um defeito ósseo simulando fratura de mandíbula em ratos
Purpose: The present study aims to verify the effect of high and low dose of methotrexate (MTX) treatment on bone repair of mandibular fractures in rats. Methods: The experimental model employed consists in creating a defect in rat mandible, similar to a fracture. Eighty rats were distributed in 4 groups of 20 animals that received, intraperitoneally: saline

20. PINO ÓSSEO HOMÓLOGO CONSERVADO EM GLICERINA A 98% NA OSTEOSSÍNTESE UMERAL DE POMBOS DOMÉSTICOS (Columba livia) / HOMOLOGOUS BONE PIN CONSERVED IN GLYCERIN AT 98% IN HUMERUS OSTEOSYNTESIS OF DOMESTIC PIGEONS. (Columba livia)
The objective of the present study was to evaluate the use of a homologous bone pin, conserved in 98 % glycerin associated to hemicerclage with 910 polyglactin in transverse humerus osteosynthesis in domestic pigeons (Columba livia). The distal part of the tibialtarsus, conserved with bone marrow, was used as a bone pin. Twenty non-sexed healthy adult domest

23. Avaliação de parâmetros ultra-sônicos utilizados na caracterização de tecidos ósseos / Assessment of Ultrasonics Parameters Utility in Customization of Bone Tissues.
A transmissão do ultra-som no organismo humano tem sido objeto de estudos a várias décadas, com a finalidade de promover diagnóstico. Recentemente tem sido usada para avaliar a densidade óssea e poder diagnosticar precocemente o aparecimento da osteoporose e prever o risco de fratura. Nesse trabalho foi desenvolvido um sistema capaz de gerar, receber e
