This study aimed to elucidate the therapeutic effects of a traditional Chinese medicine, Pai-Du-Yang-Shen (PDYS) Formula, in 5/6 nephrectomy-induced chronic renal failure (CRF). The CRF model was established via 5/6 nephrectomy (Nx) in rats. Then, PDYS (0.9 and 1.8 g/kg/day), or an equal amount of normal saline, was administrated to the rats in respective groups. Our results showed that PDYS treatment improved degeneration, fibrosis, and histopathological abnormalities of renal tissues in 5/6 Nx rats. Furthermore, the increase in serum creatinine (Scr), blood urea nitrogen (BUN), and total urinary protein (TUP) in 5/6 Nx rats was reduced by PDYS treatment. In addition, the levels of tumor necrosis factor (TNF), fibronectin (FN), and laminin (LN) that were induced in 5/6 Nx rats were also decreased by PDYS treatment. Finally, relative mRNA expression of α-smooth muscle actin (α-SMA), FN, transforming growth factor-β (TGF-β), and TNF as well as protein levels of TGF-β, NF-κB p65, and phosphorylated NF-κB p65 (p-p65) in renal tissues correlated with the concentration of TNF. In conclusion, PDYS shows therapeutic effects against CRF as determined by a reduction in markers for inflammation and fibrosis.
