Western blotting for TPH and DβH in the spinal dorsal horn with or without SCS. a Representative western blot of TPH and DβH from SNL rats with or without SCS. For the SNL+SCS group, the spinal cords were harvested after 3-h SCS. b Summary of the densitometric analysis of western blots of TPH and DβH (n = 6 in each group). “Ipsi” and “Contra” indicate the ipsilateral and the contralateral sides in SNL rats, respectively. No significant intragroup differences were noted. Data are the ratio of each intensity to the average intensity of intermembrane control and are shown as mean ± SEM; *p < 0.05 by unpaired t test.
