| A circular plastic pool (height: 35 cm, diameter: 110 cm) was filled with water (with dark ink) kept at 22–25°C. An escape platform (height: 14.5 cm, diameter: 4.5 cm) was submerged 0.5-1 cm below the surface of the water. The test was performed two times per day for 5 days. Each trial lasted for 60 s or ended as soon as the mice reached the submerged platform and remained on the platform for 10 s. Mice were allowed to swim until they found the escape platform. Escape latency of each mouse were monitored by a camera above the center of the pool connected to a SMART-LD program. Values are presented as means ± SD for 12 mice. *p<0.05, significantly different from control group (n=12), and #p<0.05 from D-G group. A: Control group; B: D-gal group; C: D-gal plus low dose of edible salt; D: D-gal plus high dose of edible salt. |
