Effect of CPP on the regulation of blood level and oxidative stress in AD mice. (a) CPP promoted insulin content after the induction of d-gal and STZ. (b & c) An oral glucose tolerance test was performed with fasted mice. The level of oxidative stress was evaluated by (d) SOD level in liver, (e) MDA content in liver, (f) CAT level in liver, and (g) GSH-px level in liver, as well as (h) CAT level in brain and (i) GSH-pxlevel in brain. Values represent the mean ± SD (n = 7). *p < 0.05, ^**p < 0.01 vs. AD mice. ^#p < 0.05, ^##p < 0.01 vs. normal mice.
