Figure 7.

The effect of 24 h exposure to 1 µg·mL⁻¹ LPS, 1 µg·mL⁻¹ LPS plus 1 µM quercetin (Quer) and 1 µg·mL⁻¹ LPS with a combination of 10 µM myricetin (Myr) and 1 µM quercetin on nitrite ion production in porcine coronary artery segments incubated in DMEM. Myricetin was added to DMEM 60 min before quercetin, which in turn was added 60 min prior to the addition of LPS. The values shown are the mean ± SEM of 12 observations. **P < 0.01 significant difference from control by anova. DMEM, Dulbecco's modified Eagle's medium; LPS, lipopolysaccharide.
