PAE effects on d-gal-induced fatigue in the weight-loaded forced swimming test (WLFST) and Pearson’s correlation between the swimming time versus thymus coefficients. The mice were individually placed into the plastic pool which containing freshwater. The mice were forced to swim in the water until exhaustion. The time that the mice were unable to keep their nose out of the water for 5 s was recorded as the exhausted swimming time. (A) The swimming times in the WLFST were recorded. Results are presented as mean ± SEM. n = 9, ## p < 0.01 vs. vehicle control group and * p < 0.05, ** p < 0.01 vs. d-gal-treated group in the WLFST. (B) Pearson’s correlation between the swimming time versus thymus coefficients was determined. C (hollow circle), M (hollow diamond), V (inverted hollow triangle), P-3 (hollow triangle), P-10 (inverted filled triangle), P-30 (filled triangle), n = 54.
