Abstract

In 1978, Pizzarello and co-workers reported that exposure of rat fetuses to diagnostic levels of ultrasound caused marked reduction in fetal weight. Replicates of these experiments have been conducted and, in addition, exposures at 10 times the peak and average intensity were used. No effect on fetal weight, numbers of living fetuses or resorptions could be attributed to ultrasound at either exposure level.

摘要

1978年，皮扎雷洛及其同事报告称，将大鼠胎儿暴露于诊断级别的超声波下会导致胎儿体重显著降低。这些实验已被重复进行，此外，还使用了峰值和平均强度10倍的超声波进行照射。在这两种照射水平下，超声波对胎儿体重、存活胎儿数量或吸收情况均未产生影响。
