CD-1 strain, female mice, aged 5 to 7 months, were mated with males of the same age. Females presenting vaginal plug were separated and randomly distributed in two groups to be treated from the 6th to 17th day of gestation. One group received single daily diazepam doses (2.7 mg/kg i.p.), the other, 0.9% saline in equivalent volumes. Females were killed on 18th day, the placentas removed and fixed in 10% formaldehyde, pH 7.3, dehydrated and embedded in paraplast; 3 microns thick sections were stained with hematoxylin-eosin and Weigert hematoxylin and analyzed under light microscopy. Placentas of the diazepam-treated females presented dilated chorion vessels and intervillous spaces. Trophoblastic cell nuclei presented chromatin in coarse granules, atypically distributed in the karyolymph, which had lesser staining affinity. Giant cells showed vacuolized cytoplasm and coarsely granulated chromatin. Results indicate that diazepam causes structural changes, possibly placental and fetal physiology.
