1 [Dexmedetomidine prevents inflammatory responses in injured rat lung tissues induced by ischemia/reperfusion through inhibition of TLR4 expression]. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
2 OBJECTIVE: To investigate the effect of Dexmedetomidine (Dex) on Toll-like receptor 4(TLR4) expression in lung during lung ischemia/reperfusion(I/R) in rats and its possible protecting mechanisms. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
3 OBJECTIVE: To investigate the effect of Dexmedetomidine (Dex) on Toll-like receptor 4(TLR4) expression in lung during lung ischemia/reperfusion(I/R) in rats and its possible protecting mechanisms. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
4 (2)Compared with those in the I/R group, W/D and TLW in the Dex group were lower (P<0.05, P<0.01), the mRNA and protein expression levels of TLR4 in lung tissues decreased (P<0.01), and reduced structure damages of lung tissues were observed under light microscopy in Dex group. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
5 (2)Compared with those in the I/R group, W/D and TLW in the Dex group were lower (P<0.05, P<0.01), the mRNA and protein expression levels of TLR4 in lung tissues decreased (P<0.01), and reduced structure damages of lung tissues were observed under light microscopy in Dex group. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
6 (3)Compared with those in the Dex group, W/D and TLW in the Dex+Atip group were higher (P<0.01), the mRNA and protein expression levels of TLR4 in lung tissues increased (P<0.01), and the structure damages of lung tissues observed under light microscopy were more serious. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
7 (3)Compared with those in the Dex group, W/D and TLW in the Dex+Atip group were higher (P<0.01), the mRNA and protein expression levels of TLR4 in lung tissues increased (P<0.01), and the structure damages of lung tissues observed under light microscopy were more serious. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
8 Dexmedetomidine could inhibit TLR4 expression and alleviate the lung ischemia/reperfusion injury, which was related to activation of alpha2-adreno receptor. Dexmedetomidine toll-like receptor 4 Rattus norvegicus
