Estudio morfológico y morfométrico del epitelio lingual de fetos de ratas intoxicadas con cobre durante la preñez
Morphologic and morphometric study of the tongue epithelium of rat fetuses after copper intoxication during pregnancy

En ratas grávidas se estudiaron los efectos de la administración intravenosa de sulfato de cobre (4 mg/kg de peso) sobre la estructura del epitelio de la mucosa lingual de sus fetos. Los exámenes histopatológicos y morfométrico revelaron, en los animales del grupo intoxicado, un epitelio más delgad...
