[Action of low-frequency ultrasound on the peritoneum, peritoneal exudate cells and the course of experimental peritonitis].
The authors studied the action of low-frequency ultrasound on rat and guinea-pig peritoneal exudate cells during aseptic peritonitis, on the intact peritoneum of these animals, and on experimental peritonitis in guinea-pigs. It was shown that ultrasound "hammers in" India ink solutions and antibacterial drugs into the peritoneum and in combination with antibiotics, it increases the guinea-pig survival rate in peritonitis. Ultrasound was not found to produce a direct bactericidal effect in vivo. Exposure of peritoneal exudate to ultrasound (1 s/cm2) demonstrated an increase in chemotaxis of neutrophil leukocytes to autologic serum and appreciable phagocytic activity. A longer exposure (up to 3-5 s/cm2 or 6-8 s/cm2) resulted in the partial damage to the peritoneum. Leukocytes, mesotheliocytes and subperitoneal striated muscles were found to be especially sensitive to ultrasound.
