Enzymatic differentiation in human amniotic cells.

R Prasad, A Werch, R H Kaufman

    American Journal of Obstetrics and Gynecology
    |December 15, 1975
    PubMed
    Summary

    Enzyme patterns in amniotic fluid cells, including lactate dehydrogenase and alpha-esterase, differed between normal and complicated pregnancies. These enzymatic changes may indicate pregnancy status and gestational variations.

    Area of Science:

    • Biochemistry
    • Prenatal Diagnostics
    • Enzymology

    Background:

    • Amniotic fluid analysis offers insights into fetal well-being.
    • Enzyme profiles can serve as biomarkers for physiological states.

    Purpose of the Study:

    • To investigate electrophoretic patterns of various enzymes in amniotic fluid cells.
    • To determine if enzyme alterations correlate with pregnancy complications or gestational stage.

    Main Methods:

    • Electrophoresis was used to analyze enzymes in noncultured amniotic fluid cells.
    • Samples were obtained from 87 women, including 33 with normal pregnancies and 54 with complicated pregnancies.

    Main Results:

    • Electrophoretic patterns of lactate dehydrogenase, alpha-esterase, and acid phosphatase varied with gestation and pregnancy status.
    • Malate dehydrogenase and protein bands showed no alterations.
    • Glucose-6-phosphate dehydrogenase and alkaline phosphatase were undetectable.
    • 6-Phosphogluconate dehydrogenase was detected in complicated pregnancies.

    Conclusions:

    • Altered enzyme patterns in amniotic fluid cells may serve as indicators of pregnancy complications.
    • Further research is needed to elucidate the specific significance of these enzymatic changes.
