PP12 is one of the recently discovered soluble tissue antigens of the placenta. During normal pregnancy maternal serum PP12 levels rise during the first 18 weeks reaching a mean peak value of 139.9 +/- 40.26 micrograms/l; after that there is a fall to a mean value of 111.9 +/- 42.39 micrograms/l between 28 and 40 weeks. Significantly higher mean serum PP12 levels were found in the third trimester in two high risk pregnancy groups (281.09 +/- 117.08 micrograms/l in pre-eclamptic toxaemia and 203.71 +/- 73.77 micrograms/l in diabetes) while serum PP12 levels remained normal (114.94 +/- 58.06 micrograms/l) in twin pregnancy. The increase of serum PP12 concentration in toxaemia and in diabetes may be of considerable diagnostic significance.
PP12是胎盘最近发现的可溶性组织抗原之一。在正常妊娠期间,孕妇血清PP12水平在孕18周前升高,平均峰值达到139.9±40.26微克/升;之后下降,在28至40周之间平均值为111.9±42.39微克/升。在两个高危妊娠组的孕晚期发现血清PP12平均水平显著更高(先兆子痫中毒组为281.09±117.08微克/升,糖尿病组为203.71±73.77微克/升),而双胎妊娠时血清PP12水平保持正常(114.94±58.06微克/升)。子痫中毒和糖尿病患者血清PP12浓度升高可能具有重要的诊断意义。
