英文摘要 | Galanin is a 29-amino acid peptide with a suggested role in nociception. The effect of galanin on wide-dynamic range neuron discharge frequency in rats with nerve ligation, used as a model of neurogenic pain, was investigated by extracellular recording methods. Seven to 14 days after sciatic nerve ligation, 0.1, 0.5 or 1 nmol of galanin was administered directly on the dorsal surface of the L3-L5 spinal cord of rats with sciatic nerve ligation. It was found that galanin inhibited the activity of wide-dynamic range neurons dose-dependently, an effect was more pronounced in sciatic nerve ligated rats than intact rats. Furthermore, when 1 nmol of galantide, the galanin antagonist, was administered on the dorsal surface of the L3-L5 spinal cord, the wide-dynamic range neuron discharge frequency increased significantly. The results suggest that galanin plays an important role in the modulation of presumed nociception in mononeuropathy. (C) 2000 Elsevier Science B.V.
