[Effect of low-frequency ultrasound on the chemotactic and phagocytic activity of peritoneal macrophages in rats].
The influence of low-frequency ultrasound on the chemotactic, ingestive and digestive activity of peritoneal macrophages in rats was studied. The intraoperative treatment of the peritoneum with ultrasound enhanced chemotactic activity 3.3-fold in comparison with that in the control animals. The digestive function of peritoneal macrophages considerably increased, the stimulation of their ingestive capacity also occurred. The activation of the phagocytic function of macrophages was observed within 7 days after a single sonar treatment. The authors believe that the stimulation of the macrophage system is probably one of the mechanisms of the sanative action of ultrasound which is used at present in purulent surgery.
