The macrophage content of amniotic fluid has been measured and the upper limit of normal on an arbitrary scale is 41. Amongst 65 amniotic fluids collected for antenatal diagnostic studies before 22weeks' gestation there were eight which had macrophage counts ranging from 82 to 6226,three of these were shown to have anencephaly and two spina bifida. The reasons for three apparently false positives are as yet undetermined. Rhesus iso-immunized amniotic fluids were found to have macrophage counts of up to 276 and a possible explanation for this is considered. It is argued that an elevated aminotic fluid macrophage count may indicate a CNS defect or possibly other fetal abnormality.
已对羊水的巨噬细胞含量进行了测量,在任意尺度上正常上限为41。在妊娠22周前为产前诊断研究收集的65份羊水中,有8份巨噬细胞计数在82至6226之间,其中3份被证实有无脑儿,2份有脊柱裂。3例假阳性的原因尚未确定。发现恒河猴同种免疫的羊水巨噬细胞计数高达276,并对此给出了一种可能的解释。有人认为羊水巨噬细胞计数升高可能表明存在中枢神经系统缺陷或其他可能的胎儿异常。
