Abstract:
Objective:To investigate the expression of matrix metalloproteinase(MMP) and tissue inhibitor of matrix metalloproteinase(TIMP)in mesangial proliferative glomerulonephritis(MsPGN) rat renal tissue and the effects of nourishing kidney and activing blood recipe of traditional Chinese medicine.Methods:Chose 54 male rats and separated them into control group, MsPGN group and treated group with nourishing kidney and activing blood recipe of traditional Chinese medicine.Chose six rats per group at the time of the second,the fourth and the eighth week.The sections were treated with HE and PAS stains and the routine pathologic study was carried.Immunohistochemical staining was used to check the expression of MMP-2,TIMP-2, membrance type metalloproteinases-1(MT1-MMP) and transforming growth factor-?1(TGF-?1).Flow Cytometry was used to check the protein expression of MMP-2,TIMP-2,MT1-MMP and TGF-?1 in rat renal tissue.Results:In MsPGN group,following with the disease progressing,the glomerulus grew graduatly,ECM became more and more,the basement membrane of glomerulus was thicker.The immunohistochemical staining showed the expression of MMP-2 and MT1-MMP was lower compared with control group,but in treated group the level was weaker,the expression of TIMP-2 and TGF-?1 was higher compared with control group,but in treated group the level was weaker too. At the fourth and the eighth week, the Flow Cytometry showed that in MsPGN group the FI of MMP-2 was lower compared with control group(P
