effect of ultrasound exposure on erythrocytes sedimentation rate

ABSTRACT

In the present work, the effect of continuous wave [CW] ultrasound with different frequencies and different intensities on erythrocytes sedimentation rate [ESR] have been studied in vitro. Ultrasound exposure to erythrocytes suspended in saline leads to a change in the sedimentation rate of the cells relative to control. It was found that the change in ESR is a function of ultrasonic intensity and frequency as well as the sonification time. This behavior may be attributed to some changes in the cells due to the nonthermal [mechanical] mechanisms of interaction between ultrasonic waves and the suspended cells
