The authors assessed during comprehensive examination of amniotic fluid obtained by transabdominal amniocentesis on account of genetic indication during the second trimester of normal pregnancy between the 15th and 22nd week of gestation four selected trace elements - Zn, Cu, Pb and Cd, using the method of atomic absorption spectrometry. One of the criteria for evaluation of the results was also the relationship of the concentration of the selected trace elements and sex of the foetus. In 157 amniotic fluids collected during the 16th-19th week of gestation they recorded a significantly elevated lead level in male foetuses. During the 17th week normal pregnancy they found also a significantly increased zinc concentration in amniotic fluid of female foetuses. The authors are so far unable to interpret these interesting results which will be the subject of future investigation.
作者在正常妊娠中期第15至22周，因遗传指征经腹羊膜腔穿刺获取羊水进行全面检查时，采用原子吸收光谱法评估了四种选定微量元素——锌、铜、铅和镉。评估结果的标准之一还包括选定微量元素浓度与胎儿性别的关系。在妊娠第16至19周收集的157份羊水中，他们记录到男性胎儿的铅水平显著升高。在妊娠第17周时，他们还发现女性胎儿羊水中的锌浓度显著增加。作者目前无法解释这些有趣的结果，这些结果将是未来研究的主题。
