最近,作者证明放射性标记哌仑西平((/sup 3/H)PZ)结合到大鼠大脑皮层、海马和纹状体中的毒蕈碱结合位点的高亲和力群体。然而,在心脏、小脑和回肠中,他们发现很少或没有(/sup 3/H)PZ结合。这些数据表明,(/sup 3/H)PZ标记毒蕈碱受体的亚群。本研究探讨了光镜放射自显影定位的3-(/sup 3/H)奎宁环二苯乙酸酯,(-)(/sup 3/H)QNB,一种拮抗剂,标记毒蕈碱受体具有相同的亲和力,并比较其定位(/sup 3/H)PZ在大鼠脑干和脊髓。
Recently, the authors demonstrated that radiolabelled pirenzepine ((/sup 3/H)PZ) bound to a high affinity population of muscarinic binding sites in the rat cerebral cortex, hippocampus, and corpus striatum. However, in the heart, cerebellum and ileum they found little or no (/sup 3/H)PZ binding. These data suggest that (/sup 3/H)PZ labels a subpopulation of muscarinic receptors. The present study examines the light microscopic autoradiographic localization of 3-(/sup 3/H)quinuclidinyl benzilate, (-)(/sup 3/H)QNB, an antagonist which labels muscarinic receptors with equal affinity and compares its localization to (/sup 3/H)PZ in the rat brainstem and spinal cord.
