Abstract:
Chorionic villi of 6-9 week normal pregnant women were obtained twenty-four hours after exposure to diagnostic ultrasound and observed under transmission electron microscope. Trophoblastic syncytium and trophoblastic cell showed remarkable ultrastructural changes which included:① cellular membrane lost its integrity, ② cytoplasm escaped into the interstitial arca, ③ endoplasmic reticulum dilated and ④ mitochondria swelled, cirstane reduced with small vesticle and irregular morphology.
