Forty-eight male Wistar rats were divided into control group (CG), continuous ultrasound treated group (CTU) and pulsed ultrasound (PTU). Animals were subjected to surgical incision. A transverse lesion was made in the biceps femoris muscle (50%). CTU (1.0 MHz) was applied at 12-hour intervals on the lesion, for three days, with 0.4 W cm-2 and three minutes of duration (six applications in the total). PTU was applied in the pulsed mode 20% (2 ms on/8 ms off), maintaining the other parameters. Fibrinogen, white and red blood cells were analyzed in the 24th, 48th and 72nd hour after the injury. PTU has reduced fibrinogen levels by 20% at the 24thh and by 30% at the 48thh (p < 0.001) and haemoglobin reduction at the 72nd hour (p < 0.001), which had already occurred during the 2nd collection in the other groups. CTU favoured erythrocyte reduction at the 48th h (p = 0.003). PTU presented an anti-inflammatory effect due to plasma fibrinogen reduction, and CTU favored haemorrhage due to the reduction of erythrocytes when applied in the first 72 hours after muscle injury. 2014 artículo científico 1679-9291 https://www.redalyc.org/articulo.oa?id=307229993005 en http://www.redalyc.org/revista.oa?id=3072 Acta Scientiarum.
