What is Thresholds for Hemorrhages in Mouse Skin and Intestine Induced by Lithotripter Shock Waves about?
Zn GVO biological effects of ultrasound should be characterized as thermal or cavitational to understand their etiology and significance. A spark-gap shock-wave lithotripter was built and used to compare cavitation-induced hemorrhages to the heat-induced petechial hemorrhages caused by continuouswave ultrasound in mouse intestine. Intestinal hemorrhages induced in anesthetized hairless mice by the lithotripter pulses involved tissue destruction with bleeding into the lumen of the intestine, and were associated with intestinal gas bubbles. Skin hemorrhages were also observed, which appared to be contusions, wlth no actual breakage of the skin. Admitistration of 100 shock waves with peak positive amplitude of 18.5 MPa produced an average of 7.6 (standard error [SE] 3.1, n = 6) intestinal hemorrhages and 45 (SE 11) skin hemorrhages. The counts and severity of hemorrhages increased with increasing numbers (3 to 300) of shock waves. Absorbers of varying thickness were used to reduce the pressure amplitude of the shock waves, which were thereby modified into low frequency ultrasound pulses. For 100 pulse exposures, apparent thresholds for effects occurred between 1.6 and 4.0 MPa for the
