Figure 4. The effects of the resveratrol-enriched rice DJ526 on motor coordination and physical strength with age-progression.
(a,b) The control (Ctrl) mice fed a NFD in which the carbohydrate source was corn starch and sucrose; The resveratrol (RS) mice fed a NFD in which the carbohydrate source was corn starch and sucrose except containing resveratrol; Dongjin (DJ) mice fed a NFD in which the corn starch and sucrose were replaced with Dongjin rice; DJ526, mice fed a NFD in which the corn starch and sucrose were replaced with the resveratrol enriched rice DJ526. The resveratrol concentration in DJ526 and RS groups was 0.69 μg/g each, and not detected in Ctrl and DJ groups. Performance of mice on the rotarod test at 36 and 54 rpm. (c) Performance of mice in the swimming test. Both tests were performed at 0, 3 and 6 month intervals. The values represent the mean ± s.d. (n = 20). Values in the figure with a superscripted letter indicate statistical significance as analyzed by an unpaired Student’s t-test; *p < 0.05, **p < 0.01.
