title: Prevention of transplacentally induced malignant diseases.
abstract: Administration of vitamin A (retinol palmitate) causes a reduction of transplacentally induced leukemias. Subsequent to a transplacental application of ENU, addition of vitamin A as a suspension to drinking water leads to a reduction of leukemia incidence to 50% as well as to a corresponding decrease of this disease as a cause of death. Yet there is no influence of vitamin A on the adenomas of the lung arising in this experimental design.
