(A) Shown is the staining of glial GTs (GLT-1 and GLAST) in the spinal dorsal horn from saline-pSNL rats, minocycline-pSNL rats, minocycline-sham rats, and saline-sham rats day 10 after surgery. Scale bar: 200 μm. (B) Bar graphs show the relative mean (±S.E.) immunostaining densities of GLT-1 and GLAST in the dorsal horn ipsilateral to the operated side day 10 after surgery. The immunostaining densities from saline-pSNL rats, minocycline-pSNL rats, and minocycline-sham rats are presented as a percentage of the immunostaining densities obtained from the saline-sham rats. Asterisks denote the statistical comparisons between the three groups. ***P < 0.01; n.s, no significant difference.
