Figure 5.

Malondialdehyde (MDA) level (A) and protein carbonyl level modified by oxidative stress (B) in the hippocampi of control rats and rats that received streptozotocin (STZ) treatment for 2, 3 and 4 weeks (STZ-2W, STZ-3W, STZ-4W, respectively).

Both of these two indices were increased in rats after STZ treatment. Differences between groups were analyzed statistically by one-way analysis of variance followed by Bonferroni's post-hoc analysis (n = 5 per group; *P < 0.05, vs. control group; #P < 0.05, vs. STZ-2W group; †P < 0.05, vs. STZ- 3W group). The bars indicate the standard error of the mean (SEM).
