Protection Effect of Zhen-Wu-Tang on Adriamycin-Induced Nephrotic Syndrome via Inhibiting Oxidative Lesions and Inflammation Damage

الملخص EN

Zhen-wu-tang (ZWT), a well-known formula in China, is widely used to treat chronic kidney diseases.

However, very little information on ZWT’s mechanism of action is currently available.

In this study, we investigated the possible protective role and underlying mechanism of ZWT on nephrotic syndrome (NS) induced by Adriamycin (intravenous injection, 6.0 mg/kg) in rats using biochemical and histopathological approaches.

ZWT decreased urine protein excretion and the serum levels of total cholesterol, triglycerides, blood urea nitrogen, and creatinine significantly in diseased rats.

A decrease in plasma levels of total protein and albumin was also recorded in nephropathic rats.

Pathological results show an improved pathological state and recovering glomerular structure in ZWT treatment groups.

ZWT decreased renal IL-8 level but increased renal IL-4 level.

In addition, rats subjected to ZWT exhibited less IgG deposition in glomerulus compared with model group.

RT-PCR results showed that ZWT decreased the mRNA expression of NF-κB p65 and increased the mRNA expression of IκB.

Furthermore, ZWT reduced the level of MDA and increased SOD activity.

These results demonstrated that ZWT ameliorated Adriamycin-induced NS in rats possibly by inhibiting Adriamycin-induced inflammation damage, enhancing body’s antioxidant capacity, thereby protecting glomerulus from injury.
