A STUDY ON THE MECHANISM OF BENAZIPRIL IN PREVENTING THE PROGERSSION OF GLOMERULOSCLEROSIS / 解放军医学杂志

nephrectomy in Wistar rats were used to replicate the animal model of focal and segmental glomerular sclerosis.Then a group of 5/6 nephrectomized rats were given Benzaipril for 20 weeks , in order to evaluate the effects of Benazipril on degradation of extracellular matrix. The results showed that Benzipril not only reduced renal pathological changes, but also significantly decreased the type Ⅳ collagen and MMP 9 deposition and down regulated the mRNA expressions of MMP 9 and TIMP 1 in the remnant kidneys of the 5/6 nephrectomized rats. It suggested that Benzipril might ameliorate glomerulosclerosis through the mechanism of modulating extracellular matrix degradation in the remnant kidney tissue.
