UVB irradiation induces rapid changes in galanin, substance P and c-fos immunoreactivity in rat dorsal root ganglia and spinal cord
Recent studies have shown that UVB irradiation induces primary and secondary hyperalgesia in rats and humans peaking about 24 h after UVB exposure. In the present study we investigated the changes in galanin, substance P and c-fos immunoreactivity in rat DRG and spinal cord at the L5 level 2–96 h after UVB irradiation. UVB irradiation of the heel area in rats almost increased the skin blood flow t
