Objective To observe the effect of Niaodu Qing Capsule(NQC) and its separated prescriptions on renal transforming growth factor ?1(TGF-?1)mRNA expression in rats with chronic renal failure(CRF).Methods SD rat models of CRF were induced by 5/6 nephrectomy,and then the CRF rats were randomized into model group,Huangqi(Radix Astragali,1.5 g?kg-1?d-1) group,Danshen(Radix Salviae Miltiorrhizae,1 g?kg-1?d-1) group,Dahuang(Radix et Rhizoma Rhei,1 g?kg-1?d-1) group,Huangqi Danshen Dahuang(1 g?kg-1?d-1) group,NQC group(1 g?kg-1?d-1).Except the model group,the rats in other groups received gastric gavage of corresponding medicine according to the experimental design.After treatment for six weeks,the levels of blood urea nitrogen(BUN) and serum creatinine(SCr) were detected,and the expression level of renal TGF-?1 mRNA was examined by reverse transcription polymerase chain reaction(RT-PCR).Results The levels of BUN and SCr were decreased in the medicated groups(P
RÉSUMÉ
[Objective] To observe the effects of spleen-strengthening and kidney-invigorating prescription (SSKTP) on nutritional status in rats with chronic renal failure (CRF) . [Methods] CRF rat models were established by 5/6 subtotal nephrectomy. Rats were divided into group A (normal control) , B (model), C (high- dose SSKIP) and D (low-dose SSKIP). Contents of serum creatinine (Cr), blood urea nitrogen (BUN), C-reactive protein (CRP), urine Cr and hemoglobin (Hb) in peripheral blood , glomerular filtration rate (GFR), area body weight (ABW) index and pathological features of renal tissues were observed. [ Results ] In SSKIP groups, Hb content and ABW index were increased (P
RÉSUMÉ
[Objective] To compare the effects of Radix Astragali (RA) and triperygium glucosides (TG) on glomerular mesangial cells (GMC) proliferation and interleukin-6 (IL-6) secretion. [Methods] GMC were cultured with in-vitro cell culture technology. Serum containing RA and serum containing TG were prepared with serum pharmacological methods. GMC proliferation was detected by methylthiazolyltetrazolium (MTT) assay and IL-6 level by enzyme-linked immunosorbent assay (ELISA) to evaluate the effect of low-, moderate- and high-dosages of RA-containing serum and TG-containing serum under the condition of GMC over-proliferation. [ Results] Different dosages of RA-containing serum and TG-containing serum inhibited GMC proliferation and IL-6 secretion in a dose-effect manner, and the inhibitory effect of high- and moderate-dosage TG and high-dosage RA was stronger. [Conclusion] Under the condition of in-vitro GMC over-proliferation, RA has the similar inhibitory effects on GMC proliferation and IL-6 secretion with TG. The combined treatment of RA and TG can reduce the dose of TG and probably has an action in increasing effect and reducing toxicity.

[Objective] To observe the effects of Niaoduling Granule (NG) on renal function in rats with chronic renal failure (CRF) and its relationship with renal transforming growth factor (TGF) ?1. [Methods] CRF rat models were established by 5/6 subtotal nephrectomy and then the model rats were randomized into model group (Group B), NG group (Group C) and placebo control group (Group D) and other 8 rats served as mimic operation group (Group A) . Biochemical indexes, metabolic parameters and pathological features in kidney were examined and expression of renal transforming growth factor (TGF) ?1 was determined by immunohistochemical assay. [Results] Renal hypofunction, disorder of electrolyte, decrease of hemoglobin and CRF features were found in Group B. After treatment, renal function was improved and glomerulus-sclerosis index (GSI) and expression of renal TGF ?1 were decreased in Groups C and D (P
RÉSUMÉ
Objective To compare the effects of Niaoduqing Tablet and Niaoduqing Granule in tre atingchronic renal failure(CRF)induced by adenine in rats,which is expected to provide some lab oratory data for the clinical applic ation and innovation of the dosage forms.Methods CRF rat models induced by adenine were administered with Niaoduqing Tabl et or Niaoduqing Granule and then the seru m levels of BUN and Scr,haematologic al and biochemical indexes and renal histolog-ical features were observed.Results Both of two forms reduced serum levels of BUN and Scr,ameliorate the electrolyte,increase the number of red blood cell,hemoglobin content and haematocrit and alleviate pathological changes of the kidney tissue.Conclusion Both Niaoduqing Tablet and Niaoduqi ng Granule is effective in treating CRF in rats and the effect of Niaoduqing Tablet in ameliorating a nemia is superior to that of Niaoduqi ng Granule.
