Intrathecal application of high doses of NO-donor compounds in the anaesthetised rat was not found to cause any induction of c-fos in spinal neurones. Furthermore, intrathecal injection of a NO-synthase (NOS) blocking drug did not alter the numbers of c-fos positive neurones induced by noxious stimulation. Additionally very little colocalization between NOS and c-fos following noxious stimulation was found. Collectively these data give no support for a role for NO in the noxiously evoked induction of c-fos. (C) 2001 Elsevier Science B.V. All rights reserved.
