羊水铁蛋白、总胆碱酯酶、真性胆碱酯酶和肌酐测定的临床意义(附107例分析)

Assay of ferritin, total choline esterase, acetyl choline esterase and creatlnine in amniotic fluid of 107 pregnancies

测定了107例孕妇羊水铁蛋白、总胆碱酯酶、真性胆碱酯酶和肌酐。结果表明,各孕月的后三种值差别无显著性,铁蛋白值有随孕月增加而下降的趋势,但到孕期末又稍有升高,羊水铁蛋白浓度与母体血红蛋白呈正相关关系,仅一例脊柱裂的铁蛋白值稍高。

The assay of ferritin, total choline esterase, acetyl choline esterase and creatinine by RIA double-tube method in amniotic fluid of 107 pregnancies showed that there were no significant differences between the last three results of different pregnant months, only the ferritin values declined during advance pregnant month and had a little raise at the end of pregnancy. The geometric average of ferritin was 78.7 μg/L. Concentration of ferritin of amniotic fluid correlatedpositively with hemoglobin of mother blood.Ferritin was>500μg/L in 5 cases, but only one case was spina bifida.
