The present study examined the anti‐hypernociceptive effect of the hecogenin (HG) in mice. For assess this effect were realized models of mechanic hypernociception induced by carrageenan (CG) and Tumor Necrosis Factor‐α (TNF‐α). The mice were pre‐treated with vehicle (saline + Tween 80 0.2%; p.o.) or HG (5, 10 and 20 mg/kg, i.p.). Thirty minutes after the treatments, were injected in region subplantar of the rear right paw: 20 μL of CG (300 μg/paw) or TNF‐α (100 pg/paw). The hypernociception was assessed in times of 0.5, 1, 2 and 3 hours after the injection of CG and TNF‐α, with digital Von Frey. It was observed that HG was able to maintain the baseline nociceptive threshold in two tests. The results suggest anti‐hypernociceptive property of HGN, probably by a mechanism inhibition of production of cytokines, which activate various reactions connected with inflammation, reducing thereby hipernociception.Financial support: FAPITEC/SE, CAPES, CNPq (Brazil).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
