Concentrations of uric acid (UA) and oxypurines (OPs) were enzymatically determined in fetal scalp plasma, amniotic fluid, and maternal venous plasma simultaneously collected during oxytocin-induced labor in 19 normal term parturient patients. Values were compared with concentrations in arterial and venous cord plasma and maternal plasma drawn immediately post partum. During labor until just before delivery fetal levels of UA were significantly lower and OP concentrations were significantly higher than the corresponding maternal levels. These differences were absent when cord and maternal concentrations were compared. It is concluded that UA and OP values in cord plasma do not reflect fetal levels during labor. The cause of this discrepancy remains obscure.
对19例足月正常分娩产妇在催产素引产过程中同时采集的胎儿头皮血浆、羊水和母体静脉血浆中的尿酸（UA）和氧嘌呤（OPs）浓度进行了酶法测定。将这些值与动脉和静脉脐血血浆以及产后立即采集的母体血浆中的浓度进行比较。在分娩过程中直至即将分娩前，胎儿的UA水平显著低于母体相应水平，而OP浓度则显著高于母体相应水平。当比较脐血和母体浓度时，这些差异并不存在。得出的结论是，脐血血浆中的UA和OP值不能反映分娩过程中的胎儿水平。这种差异的原因仍不清楚。
