The contents of Cu, Zn-superoxide dismutase and catalase isolated and purified from the rat liver at the terminal stages of alloxan diabetes were decreased by 40% and 15%, respectively, as compared to the control. It can be concluded that the decrease in superoxide dismutase and catalase activity in experimental alloxan diabetes is mainly connected with the decline in the content of these proteins at the terminal stages of the disease, this, probably, being the result of DNA degradation and RNA transport disturbances under the effect of oxygen active forms.
