摘 要:Objective: To explore the role of nitric oxide (NO), an internal vasodilative factor, in occurrence ofpregnancy induced hypertension (PIH). Methods: The antepartum and postpartum levels of NO2-/NO3-, the stable metabolic end product of NO, and those of cyclic guanosine monophosphate (cGMP) in 30 patients with PIHand 30 healthy women in their late pregnancy were measured with greiss reagent. ResultS: ① The plasma levels ofNO2-/NO3- and cGMP were significantly decreased in patients with PIH as compared with the healthy women (P<0. 05). ②In patients with PlH, the antepartum level of NO2-/NO3- was markedly lower than the postpartum one(P<O. ol ). ③There was a negative correlation between the level of plasma NO2- /NO3- and systolic blood pressurein patients with PIH (P<0. 01). ④ A positive correlation was found between the level of plasma NO2-/NO3- andthat of cGMP in patients with PIH (P<0. 01). Conclusion: The decrease of NO synthesis may play an importantrole in occurrence of PIH.Objective: To explore the role of nitric oxide (NO), an internal vasodilative factor, in occurrence ofpregnancy induced hypertension (PIH).
