(A) t-PA-positive reaction was seen in myocardial, vascular, interstitial cells of the heart tissue exposed to ultrasonic field. There was no positive reaction observed in the same tissue without ultrasound in experimental group; (B) No t-PA positive cells were found in heart tissue in control group; (C) No t-PA positive cells were found in liver; (D) No t-PA positive cells were found in kidney; immunohistochemical stain 200×; (E) No t-PA positive cells were found in lung; immunohistochemical stain 100×.
