Abstract:Interstitial fibrosis is the end-stage characteristic of chronic renal disease in the elderly and a common cause of renal failure. The use of animal models is essential for the understanding of the pathophysiology of renal interstitial fibrosis. The widely used animal models for this purpose include those with unilateral ureteral obstruction, subtotal nephrectomy, ischemia-reperfusion injury, cyclosporine A nephropathy, adriamycin nephropathy, stolochic acid nephropathy. These models were reviewed in this paper to provide a reference for the selection of a test method for better basic research.
