4 Pharmacology and Biochemistry

4.1 Metabolism/Metabolites

... In vitro experiments suggested that trace amounts of hydrogen selenide, which is an intermediate of selenite metabolism, probably induced hemolysis. For evaluation of the therapeutic value of hemoperfusion in selenium poisoning, in vitro hemoperfusion experiments were performed, which revealed only a moderate effect on selenium blood levels.
