Definition of subgroups and parameter abbreviations: C, normal control group; LPS, lipopolysaccharides-treated group; Air, room air; NO, 20 ppm nitric oxide; ONO, 95% O2 and 20 ppm NO; O, 95% O2. TPL, total phospholipids; DSPC/TPL, disaturated phosphatidylcholine to TPL ratio; TP, total proteins; DSPC/TP, DSPC to TP ratio. Values represent means ± SD (n = 8). Statistical analysis: # P < 0.05, ## P < 0.01 versus the corresponding C subgroup; * p < 0.05, ** p < 0.01 versus LPS-O.
