The neurological motor function and histological assessment of the spinal cord at 48 h after reperfusion from each group. a–f Representative sections of ventral grey matter stained with haematoxylin-eosin. Arrows indicate the viable or alive motor neurons and arrowheads indicate the necrotic or dead motor neurons. Upper scale bar = 200 μm, lower scale bar = 100 μm. g Number of intact motor neurons in the ventral grey matter. Data are presented as mean ± SEM (n = 8). h The Tarlov behaviour scores at 48 h after reperfusion from each group, each symbol represents data for one rabbit, bar = median (n = 8). **P < 0.05 versus Sham; ^##P  < 0.05 versus I/R
