Abstract:
:The effect of Co(NO3)2, CdSO4, NiSO4, ZnSO4, and HgCl2 (given repeatedly in subtoxic doses in the drinking water for 30 days) on rat liver monooxygenases was studied in experiments on male Wistar rats. The salts of Co, Cd, and Zn increased the activity of benzphetamine-N-demethylase, the content of cytochrome P-450 and microsomal heme. The data suggest that these salts exert an enzyme-inducing effect on the hepatic monooxygenases. The same metal salts (Co, Cd, and Zn) increased the activity of delta-aminolevulinic acid (ALA) synthetase and decreased that of heme oxygenase. The increased cytochrome P-450 content is probably due to the increased synthesis and the decreased breakdown of this hemoprotein. HgCl2 and NiSO4 did not exert an enzyme-inducing action. The lack of change in the activity of NADPH-cytochrome c reductase and cytochrome b5 (except for ZnSO4) suggests that these components of the electron transport chain are not likely to be involved in the enzyme-inducing action of the heavy metal salts.
