[Current data on prolactin].

Prolactin has been lately singled-out among the pituitary hormones, and as such the object of considerable research in the past 15 years. The frequency of prolactin secreting adenomes is established now. The responsibility of iatrogenic factors (neuroleptics, oral contraceptives) in some hyperprolactinaemias is a known fact. The study of the inhibiting dopaminergic system was a landmark in the treatment of hyperprolactinaemia. During the recent Nice Congress, some issues remained unsettled on the physiological activities of prolactin. The matter is clearer when it comes to prolactin secretion. In equilibrium between inhibiting and stimulant factors, the secretion is controlled by the CNS, influenced by the hormonal environment, and its timing is the object of a retrocontrol. This is a very instructive pattern in endocrinology.

[Alpha-fetoproteins in maternal serum. Radioimmunologic determination in current obstetrical practice. Analysis of 669 determinations].

The analysis of 669 levels of maternal serum alpha-fetoproteins carried out using a radio-immunological technique with double antibodies has enabled a diagram of normal values to be established on the one hand has shown up certain modifications of levels when different pathological conditions arise in pregnancy on the other hand. Raised levels were found in: intra-uterine fetal death. In some cases the rise preceded death, in twin pregnancies. Low levels were found in: severe pre-eclamptic pregnancies, in low intra-uterine fetal growth after the 32nd week, in threatened premature labour. Finally, the levels of AFP in the maternal serum were found to be normal in two cases where there were neural tube malformations. The existence of variations in the levels of AFP in maternal serum in a variety of pathological features suggests that these levels could be used as a new parameter in the biochemical monitoring of the fetus.
