[Effect of low-frequency ultrasound on the pleura and adjoining lung tissue].
Morphological changes in the pleura and adjacent pulmonary tissue were studied in 50 rabbits exposed to various doses of low-frequency ultrasound. When the exposure did not exceed 20 sec/cm2, no changes in pleural structure were noted. A longer period of exposure was followed by serous effusion. The contact of a wave-guide with the lung tissue caused the necrosis of the pleura and adjacent tissue.
