ABSTRACT

OBJECTIVE:

To evaluate the effects of Jianpi Qinghua Recipe (JPQHR) on oxygen radicals and transforming growth factor beta1 (TGFbeta1) in renal tissue in a rat model of chronic renal failure with hyperlipidemia.

METHODS:

Chronic renal failure with hyperlipidemia was induced in rats in untreated group and JPQHR-treated group by 5/6 nephrectomy and high fat diet. Then the rats in these two groups were fed distilled water and JPQHR respectively for eight weeks. The rats in normal control group received no specific interventions. After eight weeks of treatment, the levels of 24 h urine protein (Upr), blood urea nitrogen (BUN) and serum creatinine (Cr), cholesterol (Ch), triglycerides (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) of rats in these three groups were examined. The activity of superoxide dismutase (SOD), contents of malondialdehyde (MDA) and non-esterified fatty acids (NEFA) and expression level of TGFbeta1 mRNA in renal tissue of rats in each groups were also determined.

RESULTS:

The levels of 24 Upr, BUN and serum Cr, Ch, TG and LDL in the JPQHR-treated group were significantly lower than those in the untreated group. The contents of MDA and NEFA and the expression level of TGFbeta1 mRNA in the JPQHR-treated group were also significantly lower than those in the untreated group, while the activity of SOD was significantly increased in the JPQHR-treated group as compared with that in the untreated group.

CONCLUSION:

The results indicate that JPQHR can improve the renal function of rats with chronic renal failure and hyperlipidemia by regulating lipid metabolism, maintaining balance between prooxidants and antioxidants and reducing expression of TGFbeta1 mRNA in renal tissue.
