826600-4	1976	Pretreatment of rats with cobalt (30 min) produced the following changes in PCB actions on heme metabolism in liver: (a) augmentation of the porphyrinogenic effect of PCB, as determined by the total porphyrin content and ALAS activity; (b) augmentation of PCB inhibition of ALAD activity; and (c) blockade of induction of microsomal hemoprotein (cytochrome P-448).	Cobalt	26-32	aminolevulinate dehydratase	Rattus norvegicus	274-278	
1228174-9	1975	Porphobilinogen synthase [EC 4.2.1.24] activity in the liver decreased and reached its minimum value (42% of the control) 12 hr after cobalt injection.	Cobalt	134-140	aminolevulinate dehydratase	Rattus norvegicus	0-24	
1228174-16	1975	Inhibitions of 5-aminolevulinate synthase and porphobilinogen synthase activities by cobalt in vitro were not as marked as expected from in vivo experiments.	Cobalt	85-91	aminolevulinate dehydratase	Rattus norvegicus	46-70
