Fig. 2. Concentration-dependent effect of red wine and white wine on cell mediated oxidation of LDL. Incubation conditions were as described in the legend to Fig. 1 except for incubation in 24-well plates (200,000 cells/well). The mean TBARS production by the cell control (represented as 100%) = 15.1 ± 2.4 nmoles MDA/mg LDL protein. The points are the means ± SEM of four determinations done in triplicate. Red wine vs. white wine in the range of 0.05–0.5 mg EtOH/mL, p < 0.001, at 1.0 mg/mL, NS. RW = red wine; WW = white wine.
