Figure 1.Differences (S, % Change) between pre- and post-ex plasma malondialdehyde (MDA), plasma protein carbonyl content (PCC), susceptibility of non-HDL to oxidation (non-HDL), serum ceruloplasmin (CER) values and erythrocyte superoxide dismutase (SOD) and glutathione peroxidase (GPX) activities in non-smokers and smokers. Bars represent means and standard errors of means. * p<0.05 and *** p<0.001, compared to non-smokers.
