OZAWA, N., YAJIMA, A., SOH, K., TAKABAYASHI, T., SATO, S., SATO, A. and SUZUKI, M. Sister Chromatid Exchanges in Human Lymphocytes after Exposure to Pulse-Wave Ultrasound. Tohoku J. exp. Med., 1984, 143 (4), 473-480 - We have investigated the frequencies of sister chromatid exchange (SCE) induced by pulse-wave ultrasound in lymphocytes obtained from the human umbilical vein. The following results were obtained: 1) There is an increase in the frequency of SCEs with increases in acoustic power. 2) The critical acoustic power was 37.3-73mW/cm2 (spatial average temporal average, SATA). 3) Regardless of changes in pulse duration and repeated pulse frequency, if the acoustic power remains constant, the SCE frequency does not change significantly.
