采用胆碱酯酶同工酶带密度比测定法,分析100例正常羊水和31例畸胎羊水,对血污染羊水进行了鉴别。结果:①血污染羊水较正常羊水多5种ChE同工酶;②血污染羊水与外表多发性畸胎、内脏膨出、脑膜膨出等羊水ChE同工酶带的3/2密度比值均≤0.089、正常单双胎者为零、无脑儿或无脑儿合并脊柱裂的均≥0.11。上述结果不仅可校正血污染羊水,还可诊断和鉴别各种畸胎。 Using cholinesterase isozyme with density ratio assay, analysis of 100 cases of normal amniotic fluid and teratogenic amniotic fluid in 31 cases, the blood of amniotic fluid were identified. Results ① blood-stained amniotic fluid had 5 more ChE isoenzymes than normal amniotic fluid; ② blood-stained amniotic fluid and the appearance of multiple teratogenic, visceral bulge, 0.089, normal single and twins were zero, no brain or no brain children with spina bifida were ≥ 0.11. The above results not only correct blood pollution amniotic fluid, but also the diagnosis and identification of various teratogenic.
