Cognitive-Enhancing Effects of Polygalasaponin Hydrolysate in Aβ25–35-Induced Amnesic Mice
Figure 6
Effect of HPS on Aβ 25–35-induced memory deficits in the step-through passive avoidance test in mice. (a) Latency into the dark chamber, (b) time spent in the dark chamber, and (c) number of errors were detected in memory acquisition stage. 24 h later, (d) latency into the dark chamber, and (e) Number of errors were observed to assess the effect of HPS on memory consolidation. Values represent mean ± S.E.M ( in each group). Gal 3 mg/kg represents the galantamine 3 mg/kg group. , , versus sham-operation group. ; , versus model group.
