[Human placental lactogen levels in normal pregnancy monitored by serial ultrasound].
Parallel to the great use of ultrasound in diagnostical purposes the interest for biological effects of ultrasound is growing every day. The present studies of the biological action of ultrasound concerned the cytogenetic investigations as well as those of animals and men. Taking into account that the extrapolation of results from animals to men is uncertain all data obtained in human population are of utmost importance. We tried to define the possible biological action of routine diagnostical ultrasound on foetoplacental unit. Women with physiological pregnancy were exposed to ultrasound during regular antenatal control-examinations in the 20th, 30th and 38th week of gestation. The follow-up concerned HPL levels in the serum 1 hour before and 1 hour after exposure to ultrasound. There was no significant difference in concentrations of the examined hormone in both blood samples.
