Abstract: AIM: To investigate the effect of hypertonic-hyperoncotic solution(HHS)on cell volume and survival rate in human umbilical vein endothelial cells(HUVEC)suffering from hypoxia/reperfusion.METHODS: HUVEC of ECV-304 were selected and randomly divided into control grouPand experimental group.Cells in two groups were cultured in hypoxia environment(95 %nitrogen,and 5 % carbon dioxide)for 8 h,then in normal environment(95 % air,and 5 % carbon dioxide)for 16 h in control group,and in HHS for 15 min in experimental group.The cell volume and the survival rate were detected before experiment,15 min,60 min,8,8.25,16,and 24 h after experiment in two groups.RESULTS: In control group,cells became significantly inflated and the survival rate decreased in hypoxiaPeriod afterlasting 60 min and hypoxia/reperfusionPeriod(P<0.05 orP<0.01).In experimental group,cells became deflated significantly compared with control grouPat the samePeriod(P<0.01).The survival rate decreased,but significantly higher than that in control grouPat the samePeriod(P<0.05).CONCLUSION: HHS can delay RVD,keePcell volume steady,and decrease cell mortality suffering from hypoxia/reperfusion.
