The problem solved includes identification of frequencies of ultrasonic oscillations characterizing a certain type of cellular structures (i.e. the characteristic frequencies). These frequencies are registered by means of a measuring system characterized by a complex type of intrinsic resonances comprising the natural oscillations of both the cellular system and that of the media interacting with the latter. For the purpose of selective influence on a certain component of cellular systems it is proposed to expose the latter ones to ultrasonic waves of a significantly higher intensity at the aforesaid characteristic frequencies until the desired effect (up to the complete inactivation) is produced.
