Comparative study of the effects of the Ga-As (904 nm, 150mW) laser and the pulsed ultrasound of 1 MHz in inflammation of tibialis muscle of Wistar rats
This paper aims to compare the therapeutic effect of the laser As-Ga of 904nm and pulsed Ultrasound of 1 MHz applied in striated skeletal muscle of inflamed rats. The animals received an intramuscular injection of bupivacaine hydrochloride in tibialis muscle in order to induce the inflammatory process, and after 24 hours, the time was considered 0 for the initiation of therapy, using a laser and ultrasound. Samples collected the muscles of the animals were stained with Hematoxylin-Eosin and histological sections of the groups used for the analysis of the muscle tissue in relation to reducing the inflammatory process, comparing the results of the two therapies used. In this study it is suggested that both treatment with laser as with ultrasound can act as anti-inflammatory. However, the laser seems to have anti-inflammatory effect for all periods observed, while the ultrasound was only able to induce declining inflammatory response to seven days.
