title: [Topographic distribution of arsenous anhydride in pregnant mice using macroscopic autoradiography].
abstract: Radioactive arsenic trioxide is given to pregnant mice in order to complete a recent pharmacokinetics study in the same species and to investigate an eventual transplacental passage, whole body autoradiographic study is performed in the mouse after a single administration of that compound considering its fast elimination process. Both in mice and foetus a fixation has particularly kept our attention: the radioactivity is well fixed in the bone marrow and it might be related to some malformations which occur in the newborns.
