Scue attenuates Alzheimer's disease-like pathology in rats. (A) Latency of crossings and (B) average number of crossings in the Morris water maze spatial probe test of memory. Hippocampal expression of (C) Aβ, (D) SOD, (E) MDA and (F) Ach. (G) Nissl staining in the hippocampus. Scale bar, 50 µm. The expression levels of (H) Bcl-2, Bax and cleaved-caspase-3 were detected by western blotting. Densitometry analyses were conducted using β-actin as an internal reference. Representative results from repeated experiments are presented and data are presented as the mean ± standard deviation. n=6. **P<0.01, ***P<0.001 vs. the control group; #P<0.05, ##P<0.01, ###P<0.001 vs. the Aβ group. ^P<0.05, ^^P<0.01 vs. the Scu group. Aβ, amyloid β; Scu, scutellarin; Scue, scutellarein; SOD, superoxide dismutase; MDA, malondialdehyde; Ach, acetylcholine; Bcl-2, B cell lymphoma-2; Bax, apoptosis regulator BAX.
