Effects of DLPhtEtn on the body and brain weight. (A) The body weight for SAMR1 and SAMP8 mice was measured every one month from the beginning of oral administration with PEG or DLPhtEtn (1 mg/kg) through 7 months. Values represent the mean (± SEM) body weight (n = 5 for SAMR1 mice treated with PEG, 10 for SAMP8 mice treated with PEG, and 7 for SAMP8 mice treated with DLPhtEtn). (B) The weight of the brain, isolated from SAMR1 and SAMP8 mice after a series of behavioral tests, was measured. Values represent the mean (± SEM) brain weight (n = 5 for SAMR1 mice treated with PEG, 10 for SAMP8 mice treated with PEG, and 7 for SAMP8 mice treated with DLPhtEtn).
