Effects of SBF on memory retention impairment induced by composited Aβ in rats. The probe trial was used to evaluate memory retention of rats by 1 day swimming achievement on day 3 in the Morris water maze test, which was conducted on day 33 initiation of SBF treated, namely on day 81 after the operation. a Time spent swimming in the target quadrant within 60 s in the probe trial (no platform). Data were analyzed by one-way ANOVA with the multiple-range test. Mean ± SEM. n = 6. ## P < 0.01, vs. sham-operated group. *P < 0.05 vs. composited Aβ-treated group. b Typical swimming-tracking paths of rats in probe trial.
