妊娠早中期妇女胎盘组织中P物质含量的测定

MEASUREMENT OF SUBSTANCE P IN THE PACENTA TISSUES OF THE PREGNANT WOMEN IN THE EARLY AND MIDDLE PERIOD OF THE PREGNANCY

目的 :探讨 P物质对妊娠生理过程的影响。方法 :本文应用放射免疫方法 ,测定了妊娠早、中期妇女胎盘组织中 P物质 ( Substance P,SP)的含量。测定结果显示 :妊娠早、中期妇女胎盘组织中均含有 SP。早期胎盘组织中SP含量为 1 8.86± 1 .0 2 pg/ mg湿重组织 ,中期 SP含量为 2 3.4 2± 2 .53pg/ mg湿重组织。早、中期 SP含量无显著性差异。结论 :胎盘组织中含有 SP的结果提示 :SP作为一种调节肽 。

To investigate the effect of substance P on pregnancy Methods:The content of substance P in placenta tissues of the pregnant women was detected using redioimmunoassay method Results:The results showed that the placenta tissues contained substance P in the early and middle period of pregnancy The content of substance P is (18 86±1 02) pg/mg wet tissue in the early period of pregnancy and (23 42±2 53) pg/mg in the middle period Conclusion:This result suggests that substance P might play an important role in the complex process of pregnancy
