Abstract:
Objective:To study the instant and short term effects of diagnostic ultrasound on ultrastructure and hydrogen peroxide cytochemistry of human villi. Methods: Fifteen healthy women with gestational ages of 6 to 8 weeks were divided into 4 groups. Group A( n =3),B( n =4),C( n =4) and D( n =4) were exposured to diagnostic ultrasound for 0,10,20 and 20 min respectively. In group A, B, and C, the villi were taken out immediately after ultrasound exposure and were studied. In group D, the villi were taken out 3 d after ultrasound exposure. Results: The results showed that there were changes only in group C. Enlargement of endoplasmic reticulum and mitochondrial intracristal space were observed in syntrophoblast cells. In group A, B, and D, there were no evident abnormality. Conclusion: The conventional acoustic exposure of diagnostic ultrasound is safe for human villi.
