FIG 2.

Periodontal infection enhances systemic risk factors for atherosclerosis. (A) Total serum cholesterol and total triglyceride concentrations; (B) serum lipid fraction concentrations; (C) serum oxLDL concentrations; (D) aortic tissue MDA concentrations; (E) serum NO concentrations; (F) serum SAA concentrations. Chol, cholesterol; Trigly, triglycerides; CM, chylomicrons; VLDL, very-low-density lipoprotein; LDL, low-density lipoprotein; HDL, high-density lipoprotein; i, infected; c, control. All the tests were run in triplicates. Data points and error bars represent means ± SD for infected (n = 6) and control (n = 6) mice in each group unless stated otherwise. *, P < 0.05; **, P < 0.01; ***, P < 0.001 (determined by ANOVA with a Bonferroni posttest).
