ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of isoflurane, sevoflurane and desflurane on the expression of ICAM-1 and VCAM-1 in LPS-induced rat lung microvascular endothelial cells (RLMVECs).</p><p><b>METHODS</b>Cultured LPS-treated RLMVECs were exposed to 0.7, 1.0 or 2.0 minimum alveolar concentration (MAC) iosoflurane, sevoflurane or desflurane in 6 h. The protein expression of ICAM-1 and VCAM-1 was determined by Western blot analysis. The expression of ICAM-1 mRNA was detected by reverse-transcription polymerase chain reaction (RT-PCR).</p><p><b>RESULT</b>Isoflurane at concentration of 1.0 MAC up-regulated the expression of ICAM-1 in LPS-induced RLMVECs (P <0.05); while same concentrations of sevoflurane and desflurane down-regulated the expression of ICAM-1 (P<0.05). Desflurane at concentration of 2.0 MAC up-regulated the expression of ICAM-1 in non-LPS-induced RLMVECs. All the volatile anesthetics down-regulated the expression of VCAM-1 in a dose-dependent manner.</p><p><b>CONCLUSION</b>Compared to isoflurane, 1.0 MAC sevoflurane and desflurane down-regulate the expression of ICAM-1, which may be the molecule mechanism of their protective effect in acute lung injury.</p>
