Abstract:
Objective To explore the effect of panaxadiols saponin (PDS) on the oxidative damage in lung tissue in hemorrhage-lipopolysaccharides (LPS) two hits rats. Methods Forty Wistar rats were divided randomly into 4 groups: sham operational group(S group); two hits groups with hemorrhage-LPS(HL group);dexamethasone preventive therapy group (HLD group) ;panaxadiol saponins preventive therapy group(HLP group). The rats were made first-hit by hemorrhagic shock,LPS were administered intraperitoneally to make endotoxic shock and induce two hits in rats,then the model of acute lung injury (ALI) induced by two hits had been built up successfully. NO-2/NO-3,MDA content and NOS,iNOS,SOD activities were measured by 722S spectrophotometer. Results The results of pathological observation showed that there was obvious inflammatory reaction in lung tissues after two-hits,and the structure was destroied.Compared with HL group,the inflammatory reaction was reduced in HLD group and HLD group.NOS,iNOS activities and NO-2/NO-3,MDA contents were increased significantly,and SOD activity was significantly lower in HL group compared with S group(P
