Age-Related Changes in Hepatic Activity and Expression of Detoxification Enzymes in Male Rats

Figure 6

Age-related differences in specific activities of antioxidant enzymes in rat liver. The white column represents young (6-week-old) rats, and the hatched column indicates old (21-month-old) rats. Values are expressed as mean ± SD (six animals per age group) (*data with , Student’s t-test). SOD = superoxide dismutase; CAT = catalase; GPx = glutathione peroxidase; nonspecific Px = nonspecific peroxidase.
