2. Radioprotective Effect of Sodium Selenite on Mandible of Irradiated Rats
Resumo O propósito deste estudo foi testar o efeito radioprotetor do selênio na microarquitetura óssea de mandíbulas de ratos irradiados. Quarenta ratos foram separados em 4 grupos com 10 animais: grupo controle (GC), grupo irradiado (GI), grupo selenito de sódio (SSG) e grupo selenito de sódio irradiado (SSIG). Uma dose única de 0,8 mg/kg de selenito

3. Effect of low power laser in biomodulation of cultured osteoblastic cells of Wistar rats
Abstract Purpose: To analyze aspects of the biomodulating effect of light in biological tissues, bone cells from surgical explants of the femur of rats were irradiated with low intensity laser. Methods: Bone cells were cultured and irradiated with LASER light (GaAlAs). Growth, cell viability, mineralized matrix formation, total protein dosage, immunostim

4. The radiation protection role of heparin-SOD conjugate in irradiated mice
ABSTRACT Heparin-SOD conjugate (Hep-SOD) was prepared by modifying Cu,Zn-SOD with heparin. An acute radiation-induced mouse injury model was constructed to study the radiation protection effects of Hep-SOD conjugate. Fifty-six mice were randomly divided into seven groups: (I) normal control group; (II) irradiated control group; (III) positive control group (

5. The Evolving Role of Erythropoietin in Lung of Irradiated Rats
ABSTRACT The aim of the present study is to evaluate the possible curative effect of erythropoietin (EPO) on radiation-induced damage to the lung and its renin angiotensin system. EPO (200 U/100g) was i.p. injected to male rats one hour post 6 Gy whole body gamma irradiation. The animals were sacrificed after 14 days post irradiation. Irradiation induced sig

6. Low-level laser therapy associated to a resistance training protocol on bone tissue in diabetic rats
ABSTRACT Objective The present study aimed to evaluate the in vivo response of a resistance training and low-level laser therapy (LLLT) on tibias and femurs of rats with diabetes mellitus (DM). Materials and methods Forty male Wistar rats were randomly distributed into four experimental groups: control group (CG), diabetic group (DG), diabetic trained gr

7. Improvement of bone repair in diabetic rats subjected to ƛ780 nm low-level laser therapy
PURPOSE: To investigate the effect of low-level laser therapy on bone healing in diabetic rats. METHODS: Bone cavities (19 mm diameter) were performed in the femur of 72 alloxan-induced diabetic rats, which were assigned into four groups: CTR (non-diabetic control), DBT (diabetic) CTRL (non-diabetic irradiated) and DBTL (diabetic irradiated). Low-level l

9. New Bone Formation around Implants Inserted on Autologous and Xenografts Irradiated or not with IR Laser Light: A Histomorphometric Study in Rabbits
O uso de biomateriais e luz em enxertos ósseos têm sido relatados. Esse trabalho avaliou a influência do laser baixa potência - LBP no volume ósseo (VO) e superfície de contato osso-implante (COI) ao redor de implantes dentários inseridos em blocos de enxerto bovino ou autólogos incorporados, irradiados ou não, em fêmures de coelho. Vinte e quatro

10. Efeitos locais e sistêmicos da LLLT no reparo ósseo inicial de áreas com parafuso PLLA-PGA : estudo em coelhos
This study evaluated the local and systemic effects of LLLT in the initial process of bone repair after implantation of a PLLA-PGA screw in tibia of 24 New Zealand white rabbits. The sample was randomly divided into two groups, experimental and control. A PLLA-PGA screw was implanted in each tibia. In the experimental group, rabbits received applications of

11. Avaliação do comportamento do hidrogel álcool de polivinil (PVA) acetalizado e irradiado como substituto da cartilagem articular implantado em joelhos de ratos / Evaluation behavior polyvinyl alcohol (PVA) hydrogel acetalized and irradiated as substitute of articular cartilage implanted in wistar rat knees
Irradiated and acetalized polyvinyl alcohol (PVA) hydrogel was investigated as a potential material for osteochondral defect repair in articular cartilage. The in vitro cytotoxicity of the material was evaluated with Vero cells and mesenchymal stem cells from bone marrow of Wistar-Kyoto rats. For in vivo analyses, plugs of the material were implanted into de
