1. Some studies of cyclophosphamide (CP) and its metabolite acrolein in chick embryo liver were carried out in order to investigate the mechanism of the porphyrinogenic action of CP. 2. In vitro and in vivo studies revealed that CP induced but did not activate delta-aminolaevulinic acid (ALA) syntha...
