Potential Antioxidant Activity of Calcium and Selected Oxidative Stress Markers in Lead- and Cadmium-Exposed Workers

Figure 3

The concentrations of total antioxidant status (TOS), lipid hydroperoxides (LPH), malondialdehyde (MDA), lipofuscin (LPS), oxidative stress index (OSI), total antioxidant capacity (TAC), sulfhydryl groups (SH), ceruloplasmin (CER), and superoxide dismutase (SOD) in serum. Concentrations are expressed as percentage of the mean baseline values in the low-calcium-level group (L-Ca group). —comparison between the low- and high-calcium-level groups.
