Lipid profile in plasma. Total cholesterol in plasma (mg·mL⁻¹) in young (a) and old (b) C57BL/6 mice. Triglycerides in plasma (mg·mL⁻¹) in young (c) and old (d) C57BL/6 mice. Very-low-density lipoprotein (VLDL) in plasma (mg·mL⁻¹) in young (e) and old (f) C57BL/6 mice. Free fatty acids (FFA) in plasma (mmol·L⁻¹) in young (g) and old (h) C57BL/6 mice. Lipid peroxidation in plasma ([TBARS] nM·mg protein⁻¹) in young (i) and old (j) C57BL/6 mice. CT = control group; HF = high fat diet group; HFT = high fat diet + tempol group; HFA = high fat diet + apocynin group. Each bar graph represents the mean ± SEM. ANOVA (one-way) with Bonferroni's post hoc test: ^∗ p < 0.05; ^∗∗ p < 0.01, CT versus HF; ^δ p < 0.05, HFT versus HF; ^## p < 0.01, HFA versus HF (n = 5-6).
