Somatostatin analogs with affinity for opiate receptors in rat brain binding assay.

abstract：:Quantitative receptor autoradiography was used to examine the binding of [125I]-human CGRP in the dorsal horn of the L4 spinal segment of rats with a chronic constriction injury (CCI) of the sciatic nerve or unilateral dorsal rhizotomies of spinal segments L1-L6. At the times selected for study, we found no change in ...
