Effects of Chinese patent medicine Niaoduqing on adenineinduced chronic renal failure in rats

摘要

The authors made rat model of chronic renal failure by feeding the animals with foodcontaining 0.5 % adenine and treated with Niaoduqing(NDQ),a Chinese patent medicine,whichcomposed of Rhizoma Rhei,Radix Glycyrrhizae,Radix Paeoniae Alba,etc.The rats were divid-ed into four groups:model control,normal control;and two NDQ-treated groups with high andlow doses separately.The blood tests including urea nitrogen(BUN),serum creatinine(Scr),red blood cell(RBC),hemoglobin (Hb) hematocrit (HCT),sodium (Na),potassium (K),cal-cium(Ca)and phosphate(P)levels were performed atthe fourth week and the eighth week,thetime of sacrifice.The results showed that in the NDQ-treated groups the mean levels of BUN andScr were lower and the mean values of RBC,Hb and HCT,higher than those in the untreatedcontrol group.In the NDQ-treated groups,hyperphosphatemia and hypocalcemia of rats im-proved,the deposited crystals of adenine metabolite and the proliferation of fibroid tissue in kid-ney decreased.These findings indicate that NDQ can ameliorate the symptoms of chronic renalfailure and delay the progress of this disease.
