Effect of co and post-treatment of curcumin on the hippocampus acetylcholinesterase activity on rat model of AD induced by chronic administration of AlCl₃.Values are mean ± SEM. Note: CTR−: negative control group; CTR+: positive control group (treated by aluminum chloride (AlCl₃)); CUR1: co-treatment with curcumin; CUR2: post-treatment with curcumin; CTRAl: exposed to AlCl₃ for 90 days and survive 60 days without any treatment; a: p < 0.05 as compared to CTR- group; b: p < 0.05 as compared to CTR+ group; *: p < 0.05 as compared to CTRAl group, repeated measures two-way ANOVA followed by Tukey’s test for multiple comparisons.
