Abstract:
Objective To investigate the effects of isoflurane and sevonumne on apoptosis and expression of CD44 and CD54 in human lung cancer cell line A549.Methods Human lung cancer A549 cells were obtained from Shanghai Cell Biology Medical Research Institute,Chinese Academy of Sciences,and inoculated in 24 well culture plate.After being cultured for 24 h the cells were randomly divided into 3 groups:group Ⅰ control(group C);group Ⅱ isoflurane (group Iso) and group Ⅲ sevoflurane (group Sev).A 549 cells were exposed to 1.7% isoflurane and 2.5%sevoflurane for 4 h respectively in group Iso and Sev respectively,and were then cultured for another 24 h.Apoptosis and expression of CD44 and CD54 in A549 cells were detected with flow cytometer at 0 (T0),2 h(T1) and 4 h(T2) of and 24 h after(T3) exposure to isoflurane and sevoflurane.Results The percentage of apoptotic cells wag significantly higher at T2 and T3 in group Iso than in group C.The percentage of apoptotic cells was significantly higher at T1,T2 and T3 in group Sev than in group Iso and C.The expression of CD44 and CD54 at T1,T2 and T3 was significantly decreased as compared with the baseline at T0 in group Iso and Sev and was significantly lower in group Iso and Sev than in group C.Conclusion Isoflurane and sevoflurane can induce apoptesis of human lung cancer cell line A549, and sevoflurane is more effective. Isoflurane and sevoflurane can inhibit the expression of CD44 and CD54 of human lung cancer cell line A549.
