Cancer-Incidence, prevalence and mortality in the oldest-old. A comprehensive review.

abstract：:Age-related changes in the activities of superoxide dismutase, catalase, and glutathione peroxidase were determined in brain, heart, hepatocytes, intestinal mucosa, and kidney from male Fischer F344 rats. Superoxide dismutase activity decreased significantly with age in all five tissues studied. The activity of catala...
