Localization and opiate receptor binding of enkephalin, CCK and ACTH/beta-endorphin in the rat central nervous system.

abstract：:It is known that painful tissue injury evokes an increase in dynorphin in spinal neurons. It is not known, however, whether dynorphinergic systems respond similarly to the pain that accompanies peripheral neuropathy. Radioimmunoassays and immunocytochemistry were used to evaluate changes in dynorphin A(1-8) in the spi...
