Highly selective tritiated ligands and autoradiography have been used to study mu and delta binding sites as well as neutral endopeptidase-24.11 in the dorsal horn of the rat spinal cord. Two weeks and 4 months after dorsal root rhizotomy, both opioid binding sites were dramatically decreased (congruent to 60%). In contrast, the level of neutral endopeptidase-24.11 remained unaltered.
高选择性氚化配体和放射自显影术已被用于研究大鼠脊髓背角中的μ和δ结合位点以及中性内肽酶-24.11。在背根切断术后两周和四个月,两种阿片样物质结合位点均显著减少(约60%)。相比之下,中性内肽酶-24.11的水平保持不变。
