  • Title: Effects of intrathecal galanin on nociceptive responses in rats with mononeuropathy.
    Author: Yu LC, Lundeberg S, An H, Wang FX, Lundeberg T.
    Journal: Life Sci; 1999; 64(13):1145-53. PubMed ID: 10210277.
    Abstract:
    The present study was performed on rats with experimental mononeuropathy induced by left common sciatic nerve loose ligation. Unilateral sciatic nerve loose ligation induced decreases of the hindpaw withdrawal latency to the hot-plate test, cold-plate test and the Randall Selitto test. Sciatic nerve loose ligation induced hyperesponsiveness to touch at room temperature also. Intrathecal administration of either 3 or 6 nmol of galanin, but not 1 nmol, induced significant bilateral increases in hindpaw withdrawal latencies to the hot-plate test, cold-plate test and the Randall Selitto tests in rats with left mononeuropathy. The results indicate that galanin may play important roles in transmission of presumed nociceptive information in the spinal cord of mononeuropathic rats.
