Abstract

The rate of hemolysis and the decline in glutathione (GSH) in rabbit erythrocytes caused by copper (Cu) ions were determined. Prior investigations have proposed that the oxidative stress induced by Cu ion depleted the normal cell protective mechanisms. The decline in GSH has been proposed as a necessary prerequisite for hemolysis. We have observed that both GSH decline and hemolysis are Cu dependent, but are two concurrent and independent processes. We have confirmed that oxygen is a necessary reactant for hemolysis and responsible for a major portion of GSH decline. However, in the presence of Cu ion, a slow decline in GSH occurs even in a deaerated system.
