[Hormone levels in the serum of pregnant woman].

The levels of HCG, prolactin, progesterone, 17-beta estradiol and oxytocinase were simultaneously tested in one serum sample in women during the normal course of pregnancy and in those with late toxaemia of pregnancy or threatened premature labour. The significance of the deviations from the mean values measured in both groups of risk pregnancies was estimated in comparison with the values found in physiological pregnancies. On the basis of the comparison of all parameters followed, it has been found out that the deviations in the hormonal levels as measured in both groups of risk pregnancies were as a rule similar.
