[Protective effects of Qizhen Jiangtang granules in diabetic nephropathy rats]
Objective:
To study the curative and protective effects of Qizhen Jiangtang Granules in the diabetic nephropathy (DN) model rats.
Methods:
Healthy SD rats were fed a high-sucrose and high-fat diet and intraperitoneal injection of streptozotocin (STZ, 30 mg/kg) to establish the DN model. The rats were divided into six groups including normal control group,model group, positive control group, high-dosage group(200 mg/kg), medium-dosage group (100 mg/kg), and low-dosage group(50 mg/kg). After oral administration of Qizhen Jiangtang Granules for eight weeks, FBG,TG,TC, LDL-c, HDL-c, SCr and BUN levels in rats serum were determined, while the pathological damage of kidney tissue with PAS and HE staining were observed under microscope.
Results:
After treatment, TG, TC, LDL-c,SCr and BUN levels were significantly decreased(P <0. 05), and HDL-c level was significantly increased(P <0. 05). The treatment also alleviated the pathological damage of kidney tissue.
Conclusion:
Qizhen Jiangtang Granules have a protective effect against kidney damage in DN model rats. The mechanism may be related to the regulation of lipid and sugar levels in serum.
