Abstract:
Objective To explore the effect of levels and ratios of matrix nephritis metalloproteinase-2(MMP-2), -9 and inhibitor of metalloproeinase-1(TIMP-1) in the pathogenesis of children with Henoch-Schonlein purpura nephritis(HSPN),and the correlation between them and urinary micro albumin(MA).Methods Serum levels of MMP-2, -9 and TIMP-1 were determined by double antibody enzyme linked immunosorbent assay(ELISA),and urine MA was determined by immune rate nephelometry in 36 children with HSPN,16 children with simple purpura and 30 healthy controls.Results Levels of MMP-2, -9,TIMP-1 and ratios of MMP-2/ TIMP-1,MMP-9/TIMP-1 rose in acute phase of HSPN. The levels and ratios in HSPN group were higher than those in simple purpura group,and those in simple purpura group higher than those in controls (P
