[The lead concentration of the maternal serum in cases of missed abortion].

The neurotoxic effect of lead is well known, but the investigations of the pregnant women are still few. The aim of the present study is to establish whether there is difference in the concentration of lead in the blood of the pregnant women with missed abortion in comparison with women with normally developing pregnancy in the same gestational age. There were examined 35 patients with missed abortion and a control group of 26 women with normal pregnancy in the same gestational age. There were established statistically significant higher levels of lead (p < 0.001) in women with normal pregnancy (124.46 +/- 46.65 micrograms/l) in comparison with cases with missed abortion (183.73 +/- 24.16 micrograms/l). There were discussed the possible mechanisms, which can be responsible for the observed changes.
