Controlled exposure of chicken embryos to continuous 30 W/cm2, 29 kHz ultrasonic vibration in a water medium produced, in proportion to exposure, progressively retarded growth or death. Analysis supports, and observation confirms, the presence of cavitation in the water medium. The effects reported here differ substantially from published observations of megaHertz insonation of chicken embryos at similar intensities. The experiments closely resemble in method of application, frequency and intensity the operation of several ultrasonic surgical and dental instruments.
在水介质中,将鸡胚置于连续30 W/cm²、29 kHz的超声振动下进行控制性暴露,结果显示,随着暴露程度的增加,鸡胚生长逐渐迟缓或死亡。分析结果支持且观察结果证实了水介质中存在空化现象。此处报告的效应与已发表的关于以类似强度对鸡胚进行兆赫兹超声照射的观察结果有很大不同。这些实验在应用方法、频率和强度方面与几种超声外科和牙科器械的操作非常相似。
