Prenatal Exposure to Sodium Arsenite Alters Placental Glucose 1, 3, and 4 Transporters in Balb/c Mice

Figure 1

Morphologic alterations found in placentas from female mice exposed to NaAsO₂ in water. Microphotographs show the decidua (D), junction zone (JZ), and labyrinth (L) zones of murine placenta. (a) Normal morphology of murine placenta and the trophoblast giant cells (arrows) and clusters of glycogen trophoblast cells (arrowheads) are shown in JZ and near to L. Magnification 10x. (b) Infarct and deposits of fibrinoid material (FM) present in JZ and L. (c) Hemorrhagic lesion located in D zone found in placenta from a NaAsO₂ exposed female. Magnification 10x. (d) Normal appearance of the L zone present in placenta from a nonexposed female. Magnification 60x. (e) Vascular congestion (VC) located in L zone present in the placenta from a NaAsO₂ exposed female. Magnification 60x. (f) Magnification of fibrinoid material (FM) in the placenta from a female exposed to NaAsO₂. Magnification 60x. H&E stain.
