The protective effect of composite salviae dropping pills on human umbilical vein endothelial cells injured by lipopolysaccharide / 中国病理生理杂志

ABSTRACT

AIM: To observe the function and morphological change of human umbilical vein endothelial cells(HUVECs) treated with lipopolysaccharide(LPS) and composite salviae dropping pills(DSP).METHODS: HUVECs were cultured and incubated within 10 mg/L LPS for 12 hours.Different final concentrations of composite salviae dropping pills(1 g/L,0.5 g/L,0.25 g/L,0.1 g/L) were added before and after LPS treatment. Cell viability,NO,NOS,ET-1 and intracellular calcium were measured.The cells were observed under inverted microscope,inverted phase contrast microscope,laser confocal scanning microscopy and transmission electron microscope.RESULTS: When given after LPS treatment,different final concentrations of composite salviae dropping pills played a protective role(P0.05).The HUVECs injured by LPS underwent apparent morphological change after treatment with composite salviae dropping pills.CONCLUSION: Composite salviae dropping pills have an evident protective effect on human umbilical vein endothelial cells exposed to LPS.
