Abstract
Objective To observe integrin linked kinase(ILK)expression in obstructive nephropathy with renal tubular acidosis, and investigate the function of renal tubular acidosis on renal interstitial fibrosis.Methods 75 rate were divided into control group and unilateral ureteral obstruction(unilateral ureteral obstruction(UUO,n=25)group,and other 50 rats in UUO group.UUO group was divided into renal tubular acidosis (UUO1 group,n=31)group and non-renal tubular acidosis(UUO2,n=19)group,re-nal function and histology test was carried at the same time.7,14,21,28 days later after operation,the rats were killed in batches, then measured the expression of ILK in renal tissue by immunohistochemistry and western blot.Results Inflammatory cell infiltra-tion and interstitial fibrosis of UUO1 group were more serious under the light microscope than that of UUO2 group;there was only a small amount of ILK protein expression in control group,almost no FN protein deposition,expression of ILK and FN protein pre-cipitation of UUO2 group increased,and UUO1 group was more than UUO2 group.Conclusion In obstructive nephropathy,renal tubular acidosis can up-regulate expression of ILK and FN sedimentation,then lead to interstitial fibrosis promotion.关键词
