title: Effects of dibutyryl cyclic AMP and gonadotropin-releasing hormone added prior to filter sterilization of the media and variation in oxygen partial pressure on output of human chorionic gonadotropin from term placental explants.
abstract: The effect of 2 mM dibutyryl cyclic AMP (dbcAMP) and 10 and 100 micrograms/ml gonadotropin-releasing hormone (GnRH) added prior to filter sterilization and of varying oxygen partial pressure (5, 20, and 95% oxygen) were evaluated using explants from each of 4 placentas on each of 6 days of culture. There were significant differences between placentas on days 1 and 2 of culture (both p less than 0.025), and day 4 (p less than 0.05), but there were no effects of GnRH or varying oxygen partial pressure on output of human chorionic gonadotropin under the conditions evaluated.
