  1. Values are expressed as the mean ± SEM (n = 8 rats per group).
  2. HC, high-cholesterol diet; HCO, high-cholesterol enriched with onion diet.
  3. Mean values within a row with unlike superscript letters were significantly different (P < 0.05). One-way ANOVA and posterior Tamhane's T2 and Bonferroni post hoc tests were used as appropriate.
