【摘要】Objective To investigate the expression and significance of keratinocyte growth factor-1(KGF-1) in the kidneys of septic rats.Methods Eighty male Wistar rats were randomly divided into the sepsis group and sham operation group.Either group was divided into 3-hour,6-hour,12-hour,24-hour and 36-hour subgroups,with 8 rats in each.Sepsis models were established by cecum ligation perforation (CLP).The kidney and blood samples were respectively taken for pathological study.Serum creatinine (Cr) and blood urea nitrogen (BUN) level determination and leukocyte counting were performed.KGF-1 protein was detected by immunohistochemical method and the expression of KGF-1 genes by real time PCR.Results The renal tubules in sepsis group were injured most at 24h after operation,which were infiltrated by considerable neutrophilic granulocytes,leukomonocytes and mononuclear cells,with vacuolar degeneration,focal hemorrhage and necrosis under the light microscopy.Serum Cr and BUN increased from 6h after operation,and reached the peak at 24h after operation in sepsis group,which were significantly different in those of sham operation group (P< 0.01).Compared with sham operation group,the
