作者由6—21周妊娠孕妇中采集得216份血清标本,以测定人类胎盘泌乳素(HPL)浓度的正常范围。其中143例行流产术。下剩73例孕期正常,后分娩正常婴儿。母血甲胎球蛋白(AFP)浓度的正常范围依据前人的报道。作者另又测定112例妇女的129份血清标本,这些孕妇在妊娠头3个月或4—6个月均有阴道出血。妊娠延续到28周以上的共有43例,自然流产的共有69例。结果:对86例妊娠超过10周的HPL进行分析,因孕期过短则HPL水平的正常范围分布过宽,不易分辨。在此86例中,HPL水平正常者计47例(占55％),其中29例(62％)分娩,18例(38％)流产。而36例水平降低者全部流产。下余水平处于降
The authors collected 216 serum samples from 6-21 weeks of pregnant women to determine the normal range of human placental lactoprotein (HPL) concentrations. 143 cases of abortion. The remaining 73 cases of normal pregnancy, after delivery of normal infants. The normal range of maternal blood methyl feturamide (AFP) concentration is based on previous reports. The authors also measured 129 serum samples from 112 women who had vaginal bleeding during the first trimester or 4-6 months. A total of 43 cases of pregnancy extended to more than 28 weeks, a total of 69 cases of spontaneous abortion. RESULTS: Of the 86 HPLs that had been in pregnancy for more than 10 weeks, the normal range of HPL was too broadly distributed and difficult to distinguish because of the short pregnancy duration. Of the 86 patients, 47 (55%) had normal HPL levels, with 29 (62%) delivered and 18 (38%) aborted. While 36 cases of lower levels of all abortion. The remaining level is in decline
