Abstract

The ultrasonic propagation properties of the livers of rats exposed for five weeks to ethanol or carbon tetrachloride were examined. The lipid concentration nearly doubled for both treatments while protein content remained unchanged. The attenuation coefficient and speed in 51 samples were measured at 100 MHz with the scanning laser acoustic microscope. In the ethanol groups an increase of the attenuation coefficient (76%) and a decrease of speed (1.3%) compared to the pair-fed controls were observed. In the CCl4 study there was a 46% increase of the attenuation coefficient and a 0.7% decrease of speed. Results were significant to 5% according to the student's t-test.
