Abstract

The chemotherapeutic drug methotrexate (MTX) is utilized to treat various malignancies. MTX exposure during pregnancy causes miscarriages, abnormalities in newborns, and developmental delays. The current study examined the placenta’s sequential histopathological alterations following exposure to the MTX in pregnant rats. Twenty-four pregnant rats were assigned into; the control group and MTX group (0.2 mg/kg). MTX was given intraperitoneally on gestational days 11–12. Oxidative stress parameters were measured in placental homogenates. The placental specimens were evaluated by light, immunohistochemical (caspase-3 and vascular endothelial growth factor (VEGF)), and electron microscopic study. Malondialdehyde levels were significantly elevated by MTX, whereas glutathione peroxidase and superoxide dismutase levels were significantly reduced
