Figure 2. Effects of maternal hypoxia with or without vitamin C treatment on maternal circulating levels of ascorbate (A) and the indices of oxidative stress urate (B) and l-cysteine (C).

Bars represent mean ± SEM (n= 7 per group). C, control; H, hypoxia; HVC, hypoxia plus vitamin C; CVC, control plus vitamin C. Significant (P < 0.05) differences are: *versus control and hypoxia for plasma ascorbate and versus other treatments for urate and l-cysteine (one-way ANOVA and Tukey's post hoc test).
