Distribution of magnesium in the human placenta membranes.

In this work we tried to estimate the level of magnesium in the membranes of the placenta. The object of the studies referred to the sections of placenta membranes: the amniotic sac and the chorion taken from healthy women patients in labour between 37th and 41th weeks of pregnancy. The content of magnesium was assayed using atomic absorption spectrometry. An increased magnesium level in the chorion indicates faster metabolism in this layer of membrane.
