The effect of DLPhtEtn on motor activity. Open field test was carried out in SAMR1 and SAMP8 mice after oral administration with PEG or DLPhtEtn (1 mg/kg) for 7 months. The results of locomotion and rearing activities are shown in (A) and (B), respectively. Values represent the mean (± SEM) number of times from 2-min block (n = 5 for SAMR1 mice treated with PEG, 10 for SAMP8 mice treated with PEG, and 7 for SAMP8 mice treated with DLPhtEtn).
