โฆ Synopsis
In order to survive, the developing conceptus must interrupt the normal ovarian cycle of the mother and extend the production of progesterone by the corpus luteum. An unusual Type 1 interferon (IFN), related structurally to the IFN-a molecule and produced in massive amounts for only a few days by the first epithelium (trophectoderm) of the preimplantation conceptus, has been implicated as the antiluteolytic agent in sheep and cattle. IFN-a therapy during this critical period can also improve pregnancy success in sheep. It remains unclear, however, whether the trophoblast IFN have specialized biological properties or whether they are unique merely in the timing, magnitude and site of their expression.

Cytarabine and thioguanine therapy for acute myelomonocytic leukemia initiated in the tenth week of pregnancy (with the addition of vincristine and rubidomycin at 17 weeks) led to a short complete remission of the leukemia in a 24-year-old ptimigravida. This is the first case to be reported in which
The aim of this study was to obtain by transvaginal sonography in early pregnancy normal biometric charts of some fetal ratios and to evaluate the utility of these ultrasonographic indices as biometric markers for the identification of fetal chromosome abnormalities. The study population included 10
