The NO content and the NOS activity were down in the PIH pregnant women placenta.This showed that the ghrelin regulated the VEGF and influenced the the NO down.And the placenta angiospasm,blood pressure highten, and the PIH were caused also by this. The ghrelin,VEGF,Flt-1,NO and NOS were detected by the SP-immunochemistry, RQ-PCR,cell culture in vitro,ASODN and nitrate reductase in the normal pregnancy,PIH placenta and the cultured HUVEC antisense blocking ghrelin in vitro.

结果证实：PIH孕妇胎盘组织中Ghrelin，VEGF、Flt-1蛋白和mRNA水平下降与正常孕妇比较有显著性差异p＜0.05提示在PIH发病过程中Ghrelin可能对VEGF，Flt-1蛋白和mRNA的表达具有下调作用，进而影响胎盘血管网的形成和发育；NO含量与NOS活力水平在PIH孕妇胎盘组织中下降，提示Ghrelin可能通过下调VEGF的表达进一步影响血管舒张因子NO水平下降，进而引起胎盘血管痉挛，血压升高，最终导致PIH的发生。
