title: [Biological effects of ultrasonics used in diagnosis. Experimental studies on the incorporation of tritiated thymidine into rat hepatocytes].
abstract: In order to evaluate the possible effects of diagnostically employed ultrasounds on DNA turnover, 35 Wistar strain rats were subjected to an ultrasonic frequency band of 2.25 MHz for exposure times varying from 10 to 500 seconds. Upon administration of thymidine tritiate, it was observed that capacity to absorb the substance remained largely normal in those rats exposed for up to 40 seconds, but was diminished where longer exposure times were employed.
