Previous research has demonstrated that a high dose of histamine (1600 pmol) injected i.t. in mice can evoke nociceptive behaviors consisting of biting/licking along with occasional scratching. The present study was undertaken to examine the involvement of spinal N-methyl-d-aspartate (NMDA) and histamine H1 and H2 receptors in the nociceptive behaviors evoked by high-dose histamine. Co-administration of the histamine H1 receptor antagonists, d-chlorpheniramine and pyrilamine, or the histamine H2 receptor antagonists, ranitidine and zolantidine, failed to suppress the histamine-evoked nociceptive behaviors. Moreover, following histamine administration, nociceptive behaviors in histamine H1 receptor-knockout and histamine H2 receptor-knockout mice were indistinguishable from those in wild-type mice, suggesting that histamine-induced nociceptive behaviors are not mediated through histamine H1 and H2 receptors in the spinal cord. The histamine-induced nociceptive behaviors were inhibited by co-administration of the competitive NMDA receptor antagonists, d-(-)-2-amino-5-phosphonovaleric acid (D-APV) and 3-((+)-2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid (CPPA), and the ion channel blocker, (5R,10S)-(+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cycloheptene-5,10-imine maleate (MK-801). Co-administration of ifenprodil, an antagonist for both the polyamine site and the NR2B subunit of NMDA receptors, also inhibited the histamine-induced nociceptive behaviors. (R-[R, S])-α-(4-hydroxyphenyl)-β-methyl-4-(phenylmethyl)-1-piperidinepropanol hydrochloride (Ro25-6981), an antagonist of the NMDA receptor subtype containing the NR2B subunit, did not inhibit histamine-induced nociceptive behaviors, whereas these behaviors were attenuated by pretreatment with an antisense oligodeoxynucleotide against the mRNA for the NR1 subunit of the NMDA receptor. Moreover, agmatine and arcaine, antagonists for a polyamine site on the NMDA receptor, inhibited nociceptive behaviors induced by histamine. These results suggest that a polyamine site on spinal NMDA receptors is involved in eliciting the nociceptive behavioral episode following intrathecal injection of histamine.
