1. Uso do laser infravermelho em episiotomia: ensaio clínico aleatorizado / Use of infrared laser in episiotomy: a randomized controlled trial
Introdução: A episiotomia é uma ampliação cirúrgica do períneo amplamente utilizada na assistência ao parto, embora seu emprego rotineiro não seja justificado pelas evidências científicas. Está associada à dor e ao desconforto no período pós-parto. O Laser em Baixa Intensidade (LBI) vem se destacando na literatura como uma tecnologia promissor

2. Effect of gallium-arsenide laser, gallium-aluminum-arsenide laser and healing ointment on cutaneous wound healing in Wistar rats
This study determined the effects of gallium-aluminum-arsenide laser (GaAlAs), gallium-arsenide laser (GaAs) and Dersani® healing ointment on skin wounds in Wistar rats. The parameters analyzed were: type I and III collagen fiber concentrations as well as the rate of wound closure. Five wounds, 12 mm in diameter, were made on the animals’ backs. The depth

3. Effects of low-level laser therapy on human osteoblastic cells grown on titanium
The aim of this study was to investigate the effects of low-level laser therapy (LLLT) by using gallium aluminum arsenide (GaAlAs) diode laser on human osteoblastic cells grown on titanium (Ti). Osteoblastic cells were obtained by enzymatic digestion of human alveolar bone and cultured on Ti discs for up to 17 days. Cells were exposed to LLLT at 3 J/cm2 (wav

4. The effectiveness of low laser therapy in subacromial impingement syndrome: a randomized placebo controlled double-blind prospective study
OBJECTIVES: Conflicting results were reported about the effectiveness of Low level laser therapy on musculoskeletal disorders. The aim of this study was to investigate the effectiveness of 850-nm gallium arsenide aluminum (Ga-As-Al) laser therapy on pain, range of motion and disability in subacromial impingement syndrome. METHODS: A total of 52 patients (33

5. The effects of low-level laser on muscle damage caused by Bothrops neuwiedi venom
The present study aimed to assess the effects of low-level laser (660 nm) on myonecrosis caused by the insertion of Bothrops neuwiedi venom in the gastrocnemius muscle of rats. Male Wistar rats were divided into three groups (n = 24 each): Group S (0.9% saline solution); Group V (venom) and Group VLLL (venom plus low-level laser). These categories were subdi

6. Influence of the gallium arsenide laser and gallium aluminum arsenide laser and healing oitment in the cutaneous wounds in Wistar rats / Influência do laser arseneto de gálio e arseneto de gálio alumínio e pomada cicatrizante em feridas cutâneas de ratos Wistar
The present work had as objective evaluates the healing effect of the gallium aluminum arsenide (GaAsAl) 830nm (30J/cm2) (60J/cm2) laser and gallium arsenide (GaAs) 904nm (4J/cm2) laser, comparing with the Dersani ointment. The analyzed parameters were the amount of type I and III collagen fibers, and the area of contraction of the wound in the different tre
