(R,S)-3,5-dihydroxyphenylglycine (DHPG) administration didn’t affect motor function recovery. (A) Ratio of success step during grid walk test. The ratio was calculated by success steps in all steps. A success step was defined as the right forelimb step without dropping. Data are represented as mean ± S.E.M. sham-vehicle n = 3, sham-DHPG n = 3, spinal cord injury (SCI)-vehicle n = 5, SCI-DHPG n = 5. Shapiro–Wilk, Kruskal–Wallis, Steel–Dwass (***p < 0.001: vs SCI-DHPG, ^###p < 0.001: vs SCI-vehicle). (B) Success ratio of single pellet reach task. The ratio was calculated using the number of that mice could grasp and eat pellets in 30 times. Data are represented as mean ± S.E.M. sham-vehicle n = 3, sham-DHPG n = 3, SCI-vehicle n = 5, SCI-DHPG n = 5. Shapiro–Wilk test, Kruskal–Wallis, Steel–Dwass (***p < 0.001: vs SCI-DHPG, ^###p < 0.001: vs SCI-vehicle).
