Effects of Naturido on the time spent in the target quadrant and in other quadrants in a Morris water maze test with senescence-accelerated model mice (SAMP8 mice).
(A) The times spent in the target quadrant and in the other quadrants were compared on day 9, mice with normal ageing (SAMR1 mice) (n = 7), Senescence-accelerated mouse (SAMP8) mice (n = 12), SAMP8 + donepezil HCl (1250 μg/kg/day) mice (n = 11), SAMP8 + Naturido (2.5 μg/kg/day) mice (n = 14), SAMP8 + Naturido (25 μg/kg/day) mice (n = 7). (B) Representative images of the circular swimming path captured by video. Left, senescence-accelerated mice (SAMP8 mice); right, SAMP8 + Naturido (25 μg/kg/day) mice. All values are expressed as means ± SEMs. *P <0.05 vs the SAMP8 group (Dunnett test using JMP10.0.0).
