ABSTRACT
Objective To explore expression of hypoxia inducible factor-1?(HIF-1?)in kidney cells during hypoxia/reoxygenation injury,and to study the effect of Danshen on prevention of the hypoxia/reoxygenation injury to cells.Methods Human renal proximal tubular cells(HK-2)were used as the target cell.There were 3 groupscontrol group,model group,Danshen group.hypoxia/reoxygenation models after neonatal asphyxia were established with liquid paraffin covering method.Expression of HIF-1? were detected with strcp avidin biotin complex(SABC)immunohistochemistry at following different time pointshypoxia 1,4,8,12,24 h,which means 1,4,8,12,24 h respectively after hypoxia;and hypoxia/reoxygenation 1,4,8,12,24 h,which means 1,4,8,12,24 h respectively after hypoxia/reoxygenation.Results HIF-1? was expressed mainly in HK-2's nucleus.There had low expression of HIF-1? in HK-2 cells under the normal culture,and its expression level kept rising quickly during hypoxic/reoxygenatic culture,until 4 h after the beginning of reoxygenation.Compared with the study group,the expression level of HIF-1? in HK-2 cells of the Danshen group were significantly lower at different time points(Pa
