Table 3. Pre- and post-ex plasma malondialdehyde (MDA), plasma protein carbonyl content (PCC), susceptibility of non-HDL to oxidation (non-HDL ox.), serum ceruloplasmin (CER) values and erythrocyte superoxide dismutase (SOD) and glutathione peroxidase (GPX) activities in non-smokers and smokers. Data are means (median; SEM).
