Immunohistochemical analysis of pGSK3β in rat spinal dorsal horns after 7 days of CCI. To investigate the levels of pGSK-3β in the spinal dorsal horns of CCI rats, we also immunostained spinal cord sections with anti-pGSK-3β antibodies at day 7 after CCI. Cytosolic pGSK-3β was detected in the spinal dorsal horns of all groups. The levels of pGSK-3β in the CCI group were significantly decreased compared with those in the sham group (p < 0.05, n = 5, t = 9.701, df = 8). Compared with the CCI group, the levels of pGSK-3β were significantly increased in the ghrelin-treated groups (p < 0.05, n = 5, t = 6.519, df = 8). Results are presented as mean ± SD. n = 5. **p < 0.01 vs Normal group; ##p < 0.01 vs Sham group; $$p < 0.01 vs CCI group.
