Fig. 6. Immunohistochemical expression of TRPV1 in ipsilateral L5 dorsal root ganglia (DRGs) (A) and TRPV1 immunoreactivities versus the vehicle controls (B) at 56 days after treatment commencement. A : TRPV1 expression was lower in the ipsilateral DRGs of the GCSB-5 300 group than in the aceclofenac or vehicle control groups. B : Percentage decreases in TRPV1 expression were greatest in the GCSB-5 300 group than in the GCSB-5 100, GCSB-5 600, aceclofenac or vehicle control groups. Results are presented as mean±SEM. Bar=100 µm. TRPV1 : transient receptor potential vanilloid 1.
