Figure 8From: Mechanisms involved in an increment of multimodal excitability of medullary and upper cervical dorsal horn neurons following cutaneous capsaicin treatmentEffect of subcutaneous capsazepine injection into the facial skin on the noxious heat, cold or mechanical stimulus-induced pERK-LI cells in capsaicin-treated rats. A and B: Vehicle or capsazepine injection following 50°C stimulation of lateral facial skin in capsaicin-treated rats. C and D: Vehicle or capsazepine injection following 5°C stimulation of the skin in capsaicin-treated rats. E and F: Vehicle or capsazepine injection following 60g stimulation of the skin in capsaicin-treated rats. G: Mean number of pERK-LI cells in Vc and C1-C2 following noxious heat, cold or mechanical stimuli of the skin in capsaicin-treated rats receiving capsazepine (solid columns) or vehicle (open columns) subcutaneously injection. **: p<0.01. Veh for Capz: vehicle for capsazepine, Capz: capsazepine, Cap: capsaicin.Back to article page
