This study investigated the involvement of the L-arginine-nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) pathway in the antidepressant-like effect of an acute administration of memantine in the forced swimming test (FST) in mice, since this signaling pathway is supposed to play a significant role in depression. The antidepressant-like effect of(More)
This study investigated the cellular signaling pathways involved in the acute antidepressant-like action of memantine in the forced swimming test (FST) in mice. The immobility time in the FST was reduced by memantine (3-10 mg/kg, i.p.). The anti-immobility effect of memantine (3 mg/kg, i.p.) was prevented by pretreatment with H-89 (1 microg/site, i.c.v., an(More)
Inosine, an endogenous purine, is the first metabolite of adenosine in a reaction catalyzed by adenosine deaminase. This study aimed to investigate the antinociceptive effects of inosine against several models of pain in mice and rats. In mice, inosine given by systemic or central routes inhibited acetic acid-induced nociception. Furthermore, inosine also(More)
