RESUMEN
Feto-maternal transfusion is an uncommon cause of neonatal anemia due to the passage of fetal blood in maternal circulation, in an amount greater than 150-180 ml. The onset of anemia may be acute or chronic in relation to the speed of blood loss. The case that we report has intermediate features between the acute and chronic form.

Our results show in an unquestionable way that both the steroid (ethinylestradiol) and non-steroid (Ralone) estrogens studied by us were absorbed percutaneously by the rat. They also demonstrate that both estrogens affected target organs in a quite similar way being proportionally dependent upon the 1-to-1,000 ratio existing between them, as established on the basis of a known activity parameter. When one of the two estrogens is given for therapeutical purposes its systemic effects are of a dose-related type.
