Figure 3. Plasma circulation time of SOD and catalase in rats. Antioxidant enzyme samples were injected intravenously into anesthetized Sprague-Dawley rats. The activities of SOD (U) and catalase (U) remaining in the plasma were measured as a function of time. Rat plasma before injection was used as the blank for plasma enzyme activity determination. Initial glutaraldehyde concentration for polymerization reaction was 0.25%..
