“Further, capsaicin injection into isoflurane-, or sevoflurane- , anaesthetized animals reduced extracellular signal-regulated kinase 1/2 phosphorylation induced by the gases alone on both sides.”
“The total number of spinal dorsal horn neurons labelled on the ipliateral side following capsaicin injection into the isoflurane-, or sevoflurane- , anaesthetized animals was significantly less than that produced by capsaicin alone.”
