Human lymphocytes were exposed in vitro to ultrasound from two clinical devices, one of which was previously reported to have increased the frequency of sister chromatid exchanges. The ultrasonic exposures had no significant effect on the frequency of sister chromatid exchanges from three blood donors. Exposure to ultrasound also had no effect on cell cycle progression. A concomitant positive control (mitomycin C) resulted in a significant increase in sister chromatid exchanges.
将人类淋巴细胞在体外暴露于两台临床设备发出的超声波下，其中一台设备先前曾被报道会增加姐妹染色单体交换频率。对三名献血者的淋巴细胞进行超声波照射后，姐妹染色单体交换频率没有显著变化。超声波照射对细胞周期进程也没有影响。同时进行的阳性对照（丝裂霉素C）导致姐妹染色单体交换显著增加。
