Avaliação histológica e morfométrica do retalho axial oris angularis e da terapia por ondas de choque aplicados a defeito palpebral experimental em cães

Considering that the cutaneous flap can be affected by isquemic complications the extra corporeal shock wave therapy (ESWT) was described as rescue techniques. The present study was developed to analyze histological and with morfometry, twenty one skin samples treated or not with the shock wave therapy, obtained from flap's distal border, used in this study to repair eyelids' experimental defects in dogs. The flap with or without ESWT did not show any histological sign of inflammatory or atrophic alterations. Both group treated showed similar morphometrical characteristics. The ESWT with the protocol used in this study (2500 impulses at 0,15 mJ/mm 2) did not demonstrate significant clinical outcomes as a rescue technique when applied over the oris angularis flap, however results showed no signals of collateral deleterious effects.

Influência da posição e tempo de irradiação sobre a capacidade de desinfecção em forno de micro-ondas

Objective: To evaluate the variations of temperature in 2 models of domestic micro-wave ovens, single emission (F 1) and dual emission of waves (F 2), to investigate areas of higher and lower intensity of the electromagnetic field. Materials and methods: A beaker containing water (60mL, 26°C) was irradiated into each of 5 positions (front - P 1; right - P 2; posterior - P 3; left - P 4; central - P 5) within each oven (900W/ 2min). To evaluate the effectiveness of disinfection in F 2, Bacillus subtilis suspension was irradiated in each of the 5 positions for 2, 4 and 6minutes. Data were analyzed by Kruskal-Wallis and nonparametric multiple comparisons at 5% significance level. Results: 84.80°C (F 1) and 92.01°C (F 2) were mean levels of temperature. For F 1, the positions P 1, P 2, P 3 and P 5 showed similar values among them and upper than P 4, while for F 2, the positions P 1, P 2 and P 4 were similar among them and upper than P 3 and P 5. Kruskal-Wallis test found significant differences between positions and models of ovens (p<0.05). It was observed that P 2 promoted bacterial death from 4min of irradiation, while the other positions promoted disinfection at 6min of irradiation. Conclusion: The protocols of position and time specified for the various procedures in microwave ovens can be different according to the characteristics of each device due to the electromagnetic field heterogeneity. © 2011 Sociedade Portuguesa de Estomatologia e Medicina Dentária.

Determinação da densidade mineral e da elasticidade óssea após a aplicação de ondas de choque extracorpóreas no terceiro metacarpiano de equinos atletas

The porpoise of this study was to evaluate the effects of extracorporeal shock waves in third metacarpus bone from healthy horses by determination of bone elasticity. It were used 20 Thoroughbred horses, male and female, with two years old, on top of training and selected as the state healthy. At the beginning of the experiment (D0), all animals were submitted for evaluation of bone elasticity held in the third metacarpus bone. The animals were divided into two groups (Control Group - CG and Experimental Group - EG). The application of extracorporeal shock wave therapy (ESWT) was performed on the right forelimb of the animals in the experimental group in the same place evaluated for bone elasticity and was used apparatus for extracorporeal therapy of waves with 0.15 mJ/mm2 energy flux density and 2000 pulses with E6R20 probe, with focus feature of the shock wave of 20 mm. The ESWT were repeated every 21 days, a total of three sessions (D0, D21 and D42). The analysis of bone elasticity determination was realized at D21, D42 and D72. The average of speed ultrasound differed between groups at D21, D42 and D72, and the animals from EG had lower bone mineral density after applications of ESWT. There was also difference in the analysis of bone mass (Z-Score) between the groups at D21 and D42, which animals from EG showed a significant decrease in bone mass. The risk of fracture was higher in animals from experimental group at D21. It was concluded that ESWT is able to promote change in bone mineral density.
