Photomicrographs from placenta collected from mice of control and treated groups stained with H&E stain. The control placenta showing average decidua basalis (db), labyrinth zone (Lz), and glycogen cells (gc). The area of labyrinth zone showing fetal blood vessels (Fbv) and trophoblastic cells (Tc) (a–c) (H&E ×4, ×10, and ×40 respectively). d G II showing decreased area of decidua basalis (db), excess glycogen cells (gc) (H&E ×4) and labyrinth zone showing markedly congested blood vessels (arrows) with excess fibrin deposition (blue arrow) (e) (H&E ×10). f G II showing excess glycogen cells (gc) and dilated fetal blood vessels (arrows) (H&E ×40). The high power showing markedly congested fetal blood vessels (star) and some of trophoblastic cells showing pyknotic nuclei (arrows) (g) (H&E ×100). The placenta of GIII showing average decidua basalis (db), labyrinth zone (Lz), and glycogen cells (gc). The area of labyrinth zone showing fetal blood vessels (Fbv) (h, i) (H&E ×4 and ×10 respectively). The placenta of GIV (j) showing decidua basalis (db) with mild glycogen cells (gc) and markedly congested labyrinth zone (star) (H&E ×10). The area of labyrinth zone with some apoptotic cells (black arrows) (k) (H&E ×40), the higher power showing mild congested fetal blood vessels in labyrinth zone (star), with trophoblastic giant cell (arrow) (l) (H&E ×100)
