Abstract

Gestational diabetes mellitus (GDM) constitutes carbohydrate metabolism disorders that lead to severe and
sometimes life-threatening complications of pregnancy.
Materials and Method: 40 placenta biopsies with blood samples were taken from gestational diabetic
pregnant women and 20 placenta biopsies with blood samples were taken from healthy pregnant women,
the tissues were fixed,processed, embedded and cutting separately depending on procedure for enzyme
histochemical and routine histological technique and the bloodwas centrifuged.
Results: The histological changes inthe GDM group represented by villous oedema in approximately (30%)
of the GDM group, an excessive amount of collagen fibres in the villous stroma (57.5%). Syncytial knots
were formed (70 %) in addition to an excessive number of cytotrophoblast cells in about (65 %). The stromal
fibrinoid deposition was noticed in (52.5 %). Hypo-vascular villi are seen in (32.5%) also, atherosis of the
uteroplacental arteries in (40%) of biopsies. In enzyme histochemistry, the villous stroma of the GDM
grouphas a strong reaction to the G-6-P enzyme. There is a significant increase (p<0.05) in serum blood
sugar, cholesterol, blood urea in the GDM group when compared with the normoglycemic group.
Conclusions: The increment of serum blood sugar caused histologicaland enzyme histochemical alteration
during pregnancies.
