    AbstractGlucomannan (GM) is a polysaccharide obtained from Heterodermia obscurata lichens. The present study was conducted to elucidate the antinociceptive effect of GM in behavioural models of acute and chronic pain in mice. GM reduced mechanical allodynia and the levels of interleukin 1-β (IL-1β) in spinal cord and nerve in the partial sciatic nerve ligation (PSNL) model. Systemic treatment with GM inhibited the nociception induced by intraplantar injection of glutamate and by intrathecal injection of N-methyl-d-aspartic acid (NMDA), (±)-1-aminocyclopentane-trans-1,3-dicarboxylic acid (trans-ACPD), tumour necrosis factor α (TNF-α) and IL-1β. Taken together, our data demonstrate that GM has significant antinociceptive effect in acute and chronic pain, suggesting a potential interest in the development of new clinically relevant drugs for the management of pain.Copyright © 2012 Elsevier Ltd.
