Gabapentin decreases microglial cells and reverses bilateral hyperalgesia and allodynia in rats with chronic myositis

Abstract: In the present work, we investigated the antinociceptive effect of gabapentin in a chronic myositis model and its interference in spinal glial cells. Chronic myositis was induced by injection of Complete Freund Adjuvant (CFA) into the right gastrocnemius (GS) muscle of rats and tests for evaluating mechanical hyperalgesia, thermal hyperalgesia and tactile allodynia were performed. Pharmacological treatment with gabapentin was administrated intrathecally and 100μg and 200μg doses were tested. For analyzing astr… Show more

“…Este grupo também observou que ratos com dor musculoesquelética aguda induzida por injeção de carragenina, além de apresentar hiperalgesia mecânica na pata contralateral, também manifestavam hiperalgesia térmica bilateral (Radhakrishnan et al, 2003). Por outro lado, outro grupo de pesquisa demonstrou que a injeção de CFA no músculo masseter induz alodinia bilateral em ratos (Tariba Knezevic et al, 2016 (Rosa et al, 2017).…”

“…Tendo em vista pesquisas anteriores que demonstraram que astrócitos e microglia da medula espinal podem estar envolvidas na dor ipsilateral (Chacur et al, 2009;Tenschert et al, 2004) e contralateral à lesão muscular crônica de ratos (Rosa et al, 2017) (Park et al, 2008 ;Reda et al, 2016;Suto et al, 2014). (Oliveira et al, 2017;Skaper;Facci, 2012;.…”
