Ten out of 30 rats were randomly selected as normal group. Remaining 20 rats were used to establish rat model of mesangial proliferative glomerulonephritis (MsPGN), and were equally divided into model group and total glucoside of paeony (TGP) group. TGP group was given 150 mg/kg TGP by gavage, normal group and model group were given the same amount of saline by gavage. After 12 weeks of intervention, 24-h urine protein quantity, serum levels of IL-6, IFN-γ, and TNF-α ,kidney ROS and MDA levels, relative content of TGF-β1 and CTGF in TGP group were lower than that in model group (P <0.05); serum levels of IL-2 and CTLA-4,SOD levels in TGP group were higher than that in model group (P <0.05).These results indicated that TGP could reduce urinary protein quantity, inhibit inflammatory response, and reduce expression of TGF-β1 and CTGF in kidney tissue of MsPGN rats.
