Peripheral Glutamate Receptors Are Required for Hyperalgesia Induced by Capsaicin
Photomicrographs showing capsaicin-induced c-Fos-ir cells in the dorsal horn of L5 h after s.c. injection of capsaicin alone (a), combined with CPCCOEt ((b), 5 mM), with MCCG ((c), 5 mM), and with MSOP ((d), 5 mM). All data presented are mean ± SEM obtained from six animals. (a), (b), (c), and (d) ipsilateral side. Solid line indicates 100 μm.
