Studies of changes in the structure of erythrocytes by an acoustic method-the method of a constant-length interferometer-have been carried out. The method is based on the use of standing ultrasonic waves in a cylindrical resonator. In the course of the experiment, the whole human blood was taken, the erythrocytes of which were hypotonic and hypertonic solutions. The resulting suspension was placed in the acoustic cell of the analyzer. Comparison of the relative velocity of ultrasound in whole blood and after exposure to hypotonic and hypertonic solutions was performed. A clear picture of the change in the structure of erythrocytes under the influence of solutions was obtained, and all the data were obtained by acoustic measurements.
