Fig. 5. TBARS production from HDL oxidation at various concentrations of red and white wines. The incubation conditions were as described in the legend for Fig. 4 except for incubation in 24-well plates (200,000 cells/well). The mean TBARS production by the cell control (represented as 100%) = 9.7 ± 0.7 nmoles MDA/mg HDL protein. The results are the means ± SEM of four determinations done in duplicate. Red wine vs. white wine in the range of 0.05–0.5 mg EtOH/mL, p < 0.007, at 1.0 mg EtOH/mL, p = 0.0534 RW = red wine; WW = white wine.
