在胎盘组织中现已检出、提取并定量出了多种激素,如人绒毛膜促性腺激素(HCG),人绒毛膜生长激素(HCS)和一些甾体激素。某些胎盘的蛋白质激素,在结构与机能上均类似于垂体的激素。最近报告,离体的胎盘组织能合成促黄体生成素释放因子(LH-RF)。作者试图确定胎盘LH-RF的含量并分析它与胎儿性别和孕龄的关系。从自然流产,死产及子宫切除治疗性流产的孕妇得到胎盘,经病理学检查均为正常胎盘。孕龄根
A variety of hormones such as human chorionic gonadotropin (HCG), human chorionic gonadotropin (HCS), and some steroid hormones have been detected, extracted and quantified in placental tissue. Some of the placenta protein hormones, in the structure and function are similar to the pituitary hormones. Recently, it has been reported that isolated placental tissue can synthesize luteinizing hormone releasing factor (LH-RF). The authors attempted to determine the content of placental LH-RF and analyze its association with fetal sex and gestational age. Placenta was obtained from pregnant women who had spontaneous abortion, stillbirth and hysterectomy. All of them were normal placenta through pathological examination. Gestational age root
