Figure 3. Ascorbic acid levels in the kidney (A) and liver (B) of female rats treated as described in the Table 1 legend. Results were analyzed by one-way analysis of variance (ANOVA) followed by Duncan's post-hoc test: groups followed by different letters are statistically different (p ≤ 0.05) and groups followed by the same letters are statistically equal (p ≤ 0.05). Data are presented as mean ± S.E.M. (N = 6).
