The amount of Mn superoxide dismutase (MnSOD) and the activity of Cu,Zn-superoxide dismutase (CuZnSOD) have been studied in human fibroblasts of five subjects with trisomy 21 and five subjects with normal karyotype, using nuclear magnetic relaxation and polarographic methods. In the trisomic fibroblasts we have found a mean molar amount of MnSOD 25.4% lower than in the control, and an amount of...

iron is a pro-oxidant cofactor that may be linked to atherosclerosis progression. free iron catalyzes the generation of free radicals and free radicals promote the oxidation of lipids. reduction of body iron stores secondary to blood donation has been hypothesized to reduce lipid peroxidation. the aim of this study was to evaluate the association between blood donation and antioxidant enzymes a...

Superoxide anion generation plays an important role in the development of paraquat toxicity. Although superoxide dismutase mimetics (SODm) have provided protection against organ injury involving generation of superoxide anions, they often suffer problems, e.g., regarding their bioavailability or potential pro-oxidant activity. The aim here was to investigate and compare the therapeutic potentia...
