The selenium concentration of maternal and umbilical cord whole blood was determined by atomic absorption spectrophotometry in 21 parturients at term. Six placental and amniotic membrane tissue specimens were also investigated. The mean selenium concentrations in the maternal (0.73 +/- 0.15 mumol/l) and umbilical cord blood (0.77 +/- 0.18 mumol/l) were similar and without significant correlation. Placental (2.24 +/- 0.20 mumol/kg wet weight) and amniotic membrane tissue specimens (2.32 +/- 0.54 mumol/kg wet weight) also contained similar concentrations of selenium which were about 3 times higher than those in the maternal and umbilical cord blood. Low whole blood selenium concentration in Finnish parturients may be a sign of deficient nutritional intake of selenium during pregnancy. The relatively high concentration of selenium in the placenta and amniotic membranes on the other hand suggest that metabolically active organs are being provided primarily with this essential trace element.
采用原子吸收分光光度法测定了21例足月产妇母体和脐带全血中的硒浓度。还对6份胎盘和羊膜组织标本进行了研究。母体血（0.73±0.15μmol/l）和脐带血（0.77±0.18μmol/l）中的平均硒浓度相似，且无显著相关性。胎盘（2.24±0.20μmol/kg湿重）和羊膜组织标本（2.32±0.54μmol/kg湿重）中的硒浓度也相似，约为母体血和脐带血中硒浓度的3倍。芬兰产妇全血硒浓度低可能表明孕期硒营养摄入不足。另一方面，胎盘和羊膜中相对较高的硒浓度表明，代谢活跃的器官主要获得了这种必需的微量元素。
