Fig. 3From: Cognitive improvement of compound danshen in an Aβ25-35 peptide-induced rat model of Alzheimer’s diseaseEffects of CDS on the latency to the dark compartment (a) during habituation (b) 24 h retention after habituation in the step-through passive avoidance test in rats. While the treatment did not alter the latency to enter the dark compartment during habituation, treatment with Aβ25–35 decreased the latency after 24 h. CDS reversed the 24 h retention caused by Aβ25–35 in a dose-dependent manner. Values shown are means ± SD. n = 8 ~ 9; # P < 0.05 vs. Veh alone; *P < 0.05, **P < 0.01 vs. Aβ25–35 + VehBack to article page
