13. A comparative in vivo ultrasonometric evaluation of normal and delayed fracture healing in sheep tibiae
OBJECTIVE: To compare normal and delayed bone healing by measuring ultrasound conduction velocity across the bone callus. METHODS: A model of transverse linear and 5 mm resection osteotomies of sheep tibiae was used. Fourteen sheep were operated on and were divided into two groups of seven according to osteotomy type. The procedure was performed on the rig

14. Dipyrone has no effects on bone healing of tibial fractures in rats
OBJECTIVE: To evaluate the effect of dipyrone on healing of tibial fractures in rats. METHODS: Fourty-two Wistar rats were used, with mean body weight of 280g. After being anesthetized, they were submitted to closed fracture of the tibia and fibula of the right posterior paw through manual force. The rats were randomly divided into three groups: the co

15. Effect of hyperbaric oxygen therapy combined with autologous platelet concentrate applied in rabbit fibula fraction healing
OBJECTIVES: The purpose is to study the effects of hyperbaric oxygen therapy and autologous platelet concentrates in healing the fibula bone of rabbits after induced fractures. METHODS: A total of 128 male New Zealand albino rabbits, between 6-8 months old, were subjected to a total osteotomy of the proximal portion of the right fibula. After surgery, the

16. Modulação da expressão dos componentes da matriz extracelular e a modulação celular na regeneração da fratura óssea padronizada em tíbia de ratos / Modulação da expressão dos componentes da matriz extracelular e a modulação celular na regeneração da fratura óssea padronizada em tíbia de ratos / Modulation of expression extracellular matrix components and the cell modulation in regeneration of fracture bone standardized in the tibia of rats / Modulation of expression extracellular matrix components and the cell modulation in regeneration of fracture bone standardized in the tibia of rats
O propósito do presente trabalho foi investigar a participação da proliferação celular e da expressão dos componentes da matriz extracelular na cascata de eventos do processo de reparo da fratura óssea, empregando as técnicas histológica, imunohistoquímica e morfométrica, em um modelo experimental padronizado para a indução da lesão na tíbia d

17. Histomorphometric analysis of the temporal bone after change of direction of force vector of mandible: an experimental study in rabbits
OBJECTIVES: The present study aimed at performing a histological evaluation of the response of temporal bone tissue to a change of direction of the force vector of the mandible in relation to the base of the skull. MATERIAL AND METHODS: Adult rabbits were assigned into four groups with two control and four experimental animals in each group. experimental ani

18. The effects of alpha-tocopherol supplementation on fracture healing in a postmenopausal osteoporotic rat model
OBJECTIVE: Osteoporosis increases the risk of bone fractures and may impair fracture healing. The aim of this study was to investigate whether alpha-tocopherol can improve the late-phase fracture healing of osteoporotic bones in ovariectomized rats. METHOD: In total, 24 female Sprague-Dawley rats were divided into three groups. The first group was sham-opera

19. Aloenxerto ósseo cortical desvitalizado com nitrogênio líquido ¿ estudo experimental em ovelhas
Bone grafting is employed in veterinary orthopedics with a variety of purposes as for arthrodesis, spinal fusions, fracture repairs, treatment of delayed or non-unions, filling bone defects, supporting corrective osteotomy, and as replacement in limb sparing techniques for tumor resection. The allograft bone, in contrast to the autologous bone graft, is asso

20. Avaliação do reparo tecidual em defeito ósseo por microtomografia tridimensional por raio X / Evaluation of tissue repair after bone fracture using 3D X-ray microtomography
Fracture is a bone discontinuity that can be surgically produced or caused by an impact that exceeds the mechanical strength of bone by initiating a series of systemic events and specific tissue response. Radiological tests are commonly performed in clinical and animal experiments for monitoring the bone healing by providing information about the alignment o

21. Efeitos do Ãcido zoledrÃnico na consolidaÃÃo de fraturas da diÃfise femoral de ratos / Effects of zoledronic acid on fracture healing of femoral diaphysis of rats.
Femoral fractures are considered a public health problem and account for a high rate of morbidity and mortality by the occurrence of complications. They occur not only in young patients exposed to major trauma but in the elderly population as well. Most elderly patients have certain conditions, eg, osteoporosis, which further increase the risk of such fractu

22. Expression of TGF-β1 in the blood during fracture repair in an estrogen-deficient rat model
OBJECTIVES: Previous studies have reported that osteoporosis due to estrogen deficiency influences fracture healing. Transforming growth factor (TGF-b) has been found to be involved in fracture healing via the regulation of the differentiation and activation of osteoblasts and osteoclasts. The current study aimed to determine the effects of estrogen on the e

23. 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

24. Treatment with paracetamol, ketorolac or etoricoxib did not hinder alveolar bone healing: a histometric study in rats
Prostaglandins control osteoblastic and osteoclastic function under physiological or pathological conditions and are important modulators of the bone healing process. The non-steroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase (COX) activity and consequently prostaglandins synthesis. Experimental and clinical evidence has indicated a risk for r
