Abstract:
Objective:To investigate the expression of mmp-2 in mesangial proliferative glomerulonephritis(MsPGN) rat renal tissue and the effects of nourishing kidney and activating blood flow recipe of TCM. Methods: 54 Male SD rats were divided into control group, MsPGN group and treatment group with nourishing kidney and activating blood flow recipe of TCM. Immunohistochemical staining, flow cytometry, western blot and RT-PCR were used to check the protein expression of mmp-2. Results: In MsPGN group, following with the disease progressing, the glomerulus grew graduatly, ECM increased, the basement membrane of glomerulus was thicker. The immunohistochemical staining showed that the chief positive granules were deposited in glomerulus and renal tubular, the expression of mmp-2 was lower than that in control group, but in treatment group the expression of mmp-2 was higher than that in MsPGN group. Conclusion: In MsPGN renal tissue, the expression of mmp-2 was reduced, its activity was weakened. Nourishing kidney and activating blood flow recipe of TCM could induce the expression of MMP-2 and partly recover the activity. Nourishing kidney and activating blood flow recipe of TCM could resist glomerular sclerosis and postpone the course of chronic renal failure.
