OBJECTIVE: The aim of the study was to investigate the anti-inflammatory effect of sevoflurane post-conditioning on cerebral ischemia-reperfusion injury in rats.
MATERIALS AND METHODS: Thirty Sprague Dawley (SD) rats were randomly divided into 3 groups: sham operation group (Sham), ischemia/reperfusion injury (I/R) group and sevoflurane post-conditioning group (Se). Hematoxylin-eosin (HE) staining was used to observe the inflammatory response in the brain tissue. The levels of TNF-α, IL-1β, IL-6 in serum were measured by ELISA. The mRNA and protein expression of TLR4 and NF-κB p65 were detected by RT-PCR and Western blot in the brain tissue.
RESULTS: The post-conditioning of sevoflurane decreased the level of inflammatory reaction in ischemic-reperfusion rat cerebral infarction area and reduced the levels of pro-inflammatory cytokines such as TNF-α, IL-1β, IL-6 in rats with ischemia-reperfusion injury. In addition, after treatment with sevoflurane, the mRNA and protein expression of TLR4 and NF-κBp65 in TLR4/NF-κB pathway was inhibited.
CONCLUSIONS: Sevoflurane post-conditioning can decrease the inflammatory reaction in cerebral infarct area induced by cerebral ischemia-reperfusion injury in rats. The neuroprotective effect mechanism of sevoflurane may be related to TLR4/NF-κB signaling pathway.
L'articolo Effects of sevoflurane post-conditioning in cerebral ischemia-reperfusion injury via TLR4/NF-κB pathway in rats sembra essere il primo su European Review.
