RESUMEN

Several important generalizations can be made concerning the interaction of cavitation ultrasound and biological structures including cellular and molecular phenomena. Physicochemical modifications of nucleic acid bases are independent on whether the bases are individually in sonicated solution or they are incorporated within DNA molecule. The ultrasonic effects involving cavitation phenomena obey pseudomonomolecular (first-order) kinetics, as a function of the amplitude of the acoustic parameter and time of exposure.
