Abstract The effect of ultrasound at a space-averaged intensity of 0.5 W/cm2:administered for 2-5 min at frequencies of 2.9, 1.5 and 0.79 MHz and mark-space ratios of 1:4(2 ms:8 ms) and 1:1(2 ms:2 ms) was investigated on the acute oedema response of rats to intracutaneous injection of silver nitrate. Rats. anaesthetized with ether were given Evans blue intravenously and two intracutaneous injections of silver nitrate (2 × 10-6 mol) into the abdominal skin. Insonation of one skin site and mock-insonation of the other was performed immediately after the injections. Rats were killed 30 min after the injections and oedema response measured by the amount of dye leakage expressed as absorbance. Significant reduction of dye leakage occurred with treatment of injection sites with ultrasound at 0.79 MHz frequency and durations of application of 2 and 4 min for both mark-space ratios,but not with the other frequencies and durations tested. Further studies are necessary to determine the relevance of this finding to the clinical efficacy of ultrasound in certain inflammatory conditions.
