目的:了解妊娠期高血压患者脐带血NO水平。方法:采用李力等人的方法略加改进,对50例孕妇脐血一氧化氮水平分析,其中妊娠高血压组28例,正常孕妇组22例,采用硝酸还原酶法。结果:妊娠高血压组脐血NO2-/NO3-含量低于正常孕妇脐血NO2-/NO3-含量,差异有显著性(P<0.01)。结论:NO水平与血压呈负相关,了解妊娠期高血压对新生儿的影响。
Objective: To understand the umbilical cord blood NO level in hypertensive patients during pregnancy. Methods: Using the method of Li et al., A slight improvement was made. The levels of nitric oxide in cord blood of 50 pregnant women were analyzed. Among them, 28 cases of gestational hypertension and 22 cases of normal pregnant women were treated with nitrate reductase method. Results: The level of NO2- / NO3- in umbilical cord blood in gestational hypertension group was lower than that in normal pregnant women (P <0.01). CONCLUSION: The level of NO is negatively correlated with blood pressure, so as to understand the effect of gestational hypertension on newborns.
