“…In another study it was reported that one third of the US equipment were outside the standards, reducing its reliability in the application and the results 17 . In an effort to evaluate the effects and potential risks of US at high intensities in the venous system, Araújo et al 18 carried out applications in the auricular veins of rabbits. It was observed that, with an intensity of 3W/cm 2 in a continuous mode, there was the induction of venous thrombosis and significant increases in the lymphocytes, which could be observed macroscopically by edema, erythema and heat.…”

“…Como modelo animal [15][16][17][18][19][20] , foram utilizados 30 coelhos adultos jovens [15][16][17][18][19][20] , divididos em 2 grupos, da espécie Oryctolagus cuninulus [15][16][17][18][19][20] , linhagem natural, pesando mais de 2 kg, com base na literatura [15][16][17][18][19][20] . Utilizamos a veia auricular lateral da orelha direita de cada coelho.…”

“…Os animais foram submetidos à sedação com xilazina, na dose de 2 a 5 mg/kg de peso corporal, por via intramuscular profunda na face lateral da coxa do membro posterior direito 19,22 . Realizamos a remoção cuidadosa dos pelos da face dorsal da orelha direita do coelho, no nível do trajeto da veia auricular lateral (vena auricularis lateralis), que foi escolhida devido ao seu calibre se assemelhar às microvarizes dos seres humanos.…”

Eficiência do laser diodo 980 nm em comparação à da glicose a 75% na oclusão de veias da orelha de coelhosPalavras-chave: escleroterapia; terapia a laser; glucose; coelhos. AbstractBackground: The laser is a new treatment to varicose veins and there is several myths and doubts in relation to its efficacy; then, there is the need to compare it with the most commonly sclerosing solution (hypertonic glucose) used in our specialty. Objective: To compare the efficiency of the diode laser 980nm to the glucose 75% in the occlusion of veins from the ear of rabbits. Methods: Aleatory trial in laboratory animals during 21 days. The sample consisted of ears from male adult rabbits. Group L (laser): 15 ears treated with laser; group G (glucose 75%): 15 ears treated with glucose 75%. Primary variables: sclerotic and/or occluded veins. Complementary variables: volume of the managed substance, complications and weight of rabbit. The sample size was estimated in 30 ears. The statistical analysis was carried out by Fisher'' s exact test associated to the Relative Risk (RR), calculating the confidence interval of 95% for the mentioned variables.Results: The incidence of sclerosis or venous occlusion in group G was 53% (8/15; 95%CI: 27-79) and in group L was 20% (3/15; 95% CI: 4-49). Two-tailed p was 0.1281, RR using the approximation of Katz was 2.66; 95%CI: 0.87-8.15. Conclusion:The efficiency of the diode laser 980 nm in comparison to glucose 75% in occlusion of veins in this experimental model was equivalent.

“…The broad use of ultrasound therapy in several health branches made it possible to identify several different biological effects of low-intensity ultrasound (US) in a number of tissues [1][2][3][4][5][6][7][8][9][10][11][12][13][14] , namely fibrinolytic effects 9 , as well as thrombolytic 10 , lipolytic 6,8 , angiogenic 13 , enzymatic 5,14 , and oxidative effects 13 , as well as synergic in vasoactive drugs 4,5 , to name but a few 3,11 . All of these effects are directly associated with the dosages used (power, frequency, time-length), and also with the responsiveness of the biological tissue exposed, i.e.…”

Implications of dermosonic lipoclasisfor energy metabolism and body composition of healthy Wistar rats Implicações da lipoclasia dermossônica no metabolismo energético e na composição corporal de ratos Wistar saudáveis Gonçalves WLS, Cirqueira JP, Abreu GR, Moysés MR AbstractObjectives: To investigate the implications of Dermosonic lipoclasis (DLC), i.e. lipolysis on subcutaneous white adipose tissue induced by ultrasound, for the energy metabolism and body composition of healthy rats. Methods: Twenty four-month-old male Wistar rats weighting ±380g were randomly divided into two groups: 1) sham control (SC) and 2) low-intensity ultrasound therapy (LIUST). For 10 days, after sedation with 3% vaporized halothane, the animals underwent LIUST (I SATA =3MHz, 1 Wcm -2 , pulsed mode 2:8ms, 30% cycles for 3 minutes) in the infra-abdominal and inguinal regions. Weight measurements, naso-anal length and metabolic parameters (food and water intake and excretion) were monitored during the study. At the end of the treatment, blood samples were collected for biochemical analyses. Retroperitoneal (RET), perirenal (PR), epididymal (EP) and inguinal (ING) adiposity was evaluated. HOMA-IR (homeostasis model assessment) was calculated to estimate insulin resistance. For statistical analyses, the Student t test, ANOVA and the Tukey test were used, and differences were established as p<0.05. Results: Regarding body weight, the SC group (384±9g) did not show any changes, while the treated group (337±2g) showed reductions (p<0.01). This was also seen in relation to food intake: (25±1g) vs. (21±1g). There were also reductions (p<0.05) in the RET, PR and ING fat-pads, obesity index, triglyceride levels and plasma lipoprotein levels. Hyperinsulinemia without changes in glycemia characterized a state of insulin resistance, which was confirmed by HOMA-IR. Conclusions: DLC reduced the food intake and body weight and modified the fat deposition in the RET, PR and ING stores in rats. This changed the lipid profile to produce a significant state of insulin resistance.Key words: ultrasound therapy; dermosonic lipoclasis; adipose tissue; energy metabolism; insulin resistance. ResumoObjetivos: Investigar as implicações da lipoclasia dermossônica (LCD), lipólise do tecido adiposo branco subcutâneo induzido por ultrassom (US), no metabolismo energético e na composição corporal de ratos saudáveis. Métodos: Utilizaram-se 20 ratos Wistar saudáveis, com 4 meses de idade, pesando ±380g, divididos aleatoriamente em 2 grupos: 1) controle-sham (CS), 2) terapia ultrassônica de baixa intensidade (TUSBI). Durante 10 dias, após sedação (halotano-3% vaporizado), os animais eram submetidos à TUSBI (I SATA =3MHz, 1W.cm -2 , modo pulsado 2:8ms, ciclo de 30% por 3 minutos) em região infra-abdominal e inguinal. Medidas de peso, comprimento naso-anal e parâmetros metabólicos (ingestão e excreção) foram controlados durante o estudo. Ao final do tratamento, amostras de sangue foram coletadas para dosagens bioquímicas, e então avaliadas adiposidades retroperitoneal (RET...
