Representative autoradiogram of the AT₁ receptor binding in the superficial dorsal horns of the lower lumbar spinal cord segment after unilateral selective dorsal rhizotomy. (A) Autoradiogram showing the AT₁ receptor binding on the ipsilateral (lesion) and contralateral (intact) side. Arrow points to the superficial dorsal horn on the lesioned side. (B) Quantitative autoradiography of the AT₁ receptor binding. Values are means ± SEM from groups of four animals, measured individually as described under Materials and Methods, and expressed as percentage of the control. *p<0.05 vs. contralateral side (control). Scale bar = 1 mm.
