ABSTRACT
Objective To observe the expression of matrix metalloproteinase-9(MMP-9)/tissue inhibitor of metalloproteinase-1(TIMP-1) in tubulointerstitial fibrosis(TIF) rats and explore the effects of MMP-9 and TIMP-1 in TIF.Methods Forty-eight male Sprague-Dawley(SD) rats were randomly divided into sham-operated group(n=24) and model group(n=24).Results Tubulointerstitial fibrosis model was established via unilateral ureteral obstruction(UUO). Histological changes were observed in tubulointerstitium injury under microscope and immunohistochemistry staining was performed to investigate both the expression of MMP-9 and TIMP-1 in TIF by semiquantitative score at d7, d14, d21 after experiment onset.The expressions of TIMP-1 in rats from sham-operated group were lower than those of mo-del group rats at d7, d14, d21 (Pa
