The effect of DLPhtEtn on fear memory. In the passive avoidance test, the acquisition latency was measured in SAMR1 and SAMP8 mice after oral administration with PEG or DLPhtEtn (1 mg/kg) for 7 months, and 24 h later the retention latency was monitored. Values represent the mean (± SEM) latency (n = 5 for SAMR1 mice treated with PEG, 10 for SAMP8 mice treated with PEG, and 7 for SAMP8 mice treated with DLPhtEtn). P value, unpaired t-test.
