Abstract
Traditional Chinese herbal medications (TCHM) are frequently used in conjunction with western pharmacotherapy for treatment of chronic kidney diseases (CKD) in China and many other Asian countries. The practice of traditional Chinese medicine is guided by cumulative empiric experience. Recent in vitro and animal studies have confirmed the biological activity and therapeutic effects of several TCHM in CKD. However, the level of evidence supporting TCHM is limited to small, non-randomized trials. Due to variations in the prescription pattern of TCHM and the need for frequent dosage adjustment, which are inherent to the practice of traditional Chinese medicine, it has been challenging to design and implement large randomized clinical trials of TCHM. Several TCHM are associated with significant adverse effects, including nephrotoxicity. However, reporting of adverse effects associated with TCHM has been inadequate. To fully realize the therapeutic use of TCHM in CKD we need molecular studies to identify active ingredients of TCHM and their mechanism of action, rigorous pharmacologic studies to determine the safety and meet regulatory standards required for clinical therapeutic agents, and well-designed clinical trials to provide evidence-based support of their safety and efficacy.

Abstract
Background Diabetic nephropathy is an emergent issue in China with increase in patients with type II diabetes. There are several successful Chinese herbal products for the treatment of patients with diabetic nephropathy in China. However, the mechanisms mediating the biological activity of these products are still unclear. Podocalyxin is a sialoprotein critical to maintaining integrity of filtration function of glomerulus. Methods By employing streptozotocin-induced diabetic rats and a Chinese herb formulation (Yishen capsule), we examined the regulation of podocalyxin expression in the kidney by Yishen capsule through immunofluorescent staining and reverse transcriptase polymerase chain reaction. Results After injection of STZ, there were significant increase in both blood glucose and urinary protein. Serum creatinine and BUN were also increased in rats with injection of STZ. Moreover, expression of podocalyxin in the glomerulus was gradually reduced after injection of STZ. There was also a loss of podocyte foot processes in the glomerular basement membrane. However, Yishen capsule or benazepril was able to restore the expression of podocalyxin and podocyte foot processes in the kidney. Although Yishen capsule could reduce urinary protein level, it has little effect on blood glucose level in the rats injected with STZ. Conclusions Yishen capsule could attenuate the loss of podocalyxin in the glomerulus of rats injected with STZ.

Abstract
BACKGROUND The Chinese herbal formula Qilong-Lishui granule (QLG) is an effective natural product for treatment of renal disorder. It was composed of six Chinese herbs according to our clinical practice in the treatment of patients with kidney disease. However, molecular and cellular mechanisms of QLG are still unclear. Therefore, the objective of the current study is to investigate molecular and cellular mechanisms of QLG in puromycin aminonucleoside (PAN)-induced nephrotic syndrome. METHOD Wistar rats were divided into six groups of sham operation, PAN model, PAN model with high-dosage QLG (QLG-H), PAN model with median-dosage QLG (QLG-M), PAN model with low-dosage QLG (QLG-L), and PAN model with fosinopril (FP). The PAN model was induced by jugular vein injection of PAN at a dose of 5 mg/100 g body weight. Quantities of 24 h urinary protein excretion were examined on days 5, 10, 15, 20, 25 and 30. All rats were sacrificed on day 31 for blood biochemistry, kidney histology and reverse transcriptase-polymerase chain reaction analysis. RESULTS PAN-induced nephrotic syndrome was successfully produced in rats. Treatment of QLG significantly reduced protein excretion and blood urea nitrogen and creatinine. QLG and FP treatments also improved protein content in blood, and reduced total cholesterol and triglyceride in blood. Moreover, QLG and FP improved the damage of interstitial induced by PAN. Furthermore, CYP and FP were able to reverse BMPRII and Smad1 mRNAs abundance caused by PAN. CONCLUSION QLG attenuates PAN-induced kidney injury possibly through the bone morphogenetic protein signal transduction pathway.

Abstract
Chronic kidney disease (CKD) is an increasingly common condition with limited treatment options that is placing a major financial and emotional burden on the community. The use of complementary and alternative medicines (CAMS) has increased many-fold over the past decade. Although several compelling studies show renal toxicities and an adverse outcome from use of some CAMS, there is also emerging evidence in the literature that some may be renoprotective. Many nephrologists are unaware of these potential therapeutic benefits in treating CKD, or they are reluctant to consider them in research trials for fear of adverse effects (including nephrotoxicity) or deleterious interaction with co-prescribed, conventional medicines. The increased use of self-prescribed CAMS by their patients suggests that practitioners and researchers should keep abreast of the current information on these agents. A primary goal of this article was to review the available scientific evidence for the use of herbs or natural substances as a complementary treatment for patients with CKD. A further goal was to report the literature on herbs that have been reported to cause kidney failure.

Abstract
BACKGROUND In order to clarify the diuretic mechanisms of Saireito, a Japanese herbal medicine, the mineralcorticoid receptor antagonistic action of Saireito was evaluated in anti-glomerular basement membrane (GBM) nephritic rats. METHODS Anti-GBM nephritis was induced in rats by the intravenous, injection of anti-GBM serum, and test drugs were administered 5 days after the induction of nephritis. In addition, we also investigated aldosterone-loaded mice to clarify the effects of test drugs on aldosterone signal transduction. In an in vitro study, a mineralocorticoid receptor binding assay of the components of Saireito was performed. RESULTS Saireito and spironolactone inhibited the development of proteinuria and abdominal ascites in anti-GBM nephritic rats. Saireito and spironolactone increased the urine volume and decreased the abdominal saline content in aldosterone-loaded mice. Saikosaponin H, a component of Saireito, inhibited the receptor binding of aldosterone in the in vitro assay 50% inhibitory concentration ([IC(50)], 22 micromol/l). Saikosaponin H also inihibited the decrease in urine volume in aldosterone-loaded mice. CONCLUSIONS These results suggest that the diuretic action of Saireito may be partly due to an antagonistic action on the mineralocorticoid receptor, exerted by saikosaponin H.

Abstract
AIMS Mesangioproliferative glomerulonephritis is a common kidney disease and at present, there is no effective treatment. Our previous studies have demonstrated that Sairei-to can significantly prevent progression of experimental glomerulonephritis in rats. Although we have reported that the active component of Sairei-to in treatment of glomerulonephritis was Saikosaponin-d (Ssd), mechanism of Ssd in prevention of mesangioproliferative glomerulonephritis progression is still unknown. Therefore, current study examines the effects of Ssd on progression of mesangioproliferative glomerulonephritis induced by anti-Thy1 monoclonal antibody 1-22-3 (mAb 1-22-3) in uninephrectomized rats. METHODS Eighteen female Wistar rats first received uninephrectomy and mAb 1-22-3 injection and were then divided into 3 groups: treated daily with phosphate-buffered saline (PBS), 0.6 or 1.8 mg/kg of Ssd. Urinary protein concentration and systolic blood pressure were evaluated and the kidneys were collected and subjected to histological and immunohistological evaluation. The mRNA and protein of the kidneys were extracted and subjected to reverse transcriptase polymerase chain reaction and Western blot analysis, respectively. RESULTS Ssd reduced the amount of urinary protein and systolic blood pressure. Ssd administration also decreased extracellular matrix expansion, crescentic formation as well as infiltration of macrophages and CD8+ T lymphocytes. Moreover, Ssd significantly reduced expression of transforming growth factor beta 1 (TGF-beta1) and type I collagen in the kidneys. CONCLUSION Ssd inhibits the progression of mesangioproliferative glomerulonephritis through reduction of the expression of TGF-beta1 and the infiltration of macrophages and CD8+ T lymphocytes.

Abstract
In this second of two articles regarding the renal toxicities or benefits of medicinal herbs, herbs are reported as being 'potentially beneficial' to the kidneys if there is strong in vivo evidence of renal protection from toxic substances or drugs; potent, specific renal anti-oxidant effects; in vivo cancer antiproliferative effects specific to the kidneys; or in vivo evidence of being beneficial in renal disease or failure. Among the herbs, polyherbal formulae and fungi with potential renal benefits are Cordyceps sinensis, Sairei-to, Rheum spp., Salvia miltiorrhiza and its component, magnesium lithospermate B and others.

Abstract
BACKGROUND Nephrin is identified as a product of the gene mutated in a patient with congenital nephrotic syndrome of the Finnish type. However, its precise localization and function are not yet fully clarified. METHODS To clone the rat homologue of nephrin, polymerase chain reaction (PCR) was employed. To elucidate the localization and expression of nephrin, immunohistological analysis with a specific antirat nephrin antibody, reverse transcription-PCR, and RNase protection assay were performed. RESULTS Amino acid sequences of rat and human nephrin are highly homologous (82.2% identity). The domain structure of nephrin is also highly conserved between rats and humans. The rat nephrin was detected only in kidney glomeruli along glomerular capillary walls, and its localization was always identical to that of the anti-slit diaphragm monoclonal antibody (mAb) 5-1-6-recognized antigen in normal matured and fetal rat glomeruli and in the glomeruli of proteinuric states. The nephrin staining pattern was clearly distinguished from that of zonula occludens-1 (ZO-1), alpha3-integrin, or podocalyxin. mRNA expression for nephrin was first detected in the fetal rat kidneys at 18.5 embryonic days. Nephrin mRNA expression decreased just after injection of mAb 5-1-6 (47.4%) or puromycin aminonucleoside (51.2%), and the staining pattern of nephrin shifted from a linear to a granular pattern in both proteinuric states. CONCLUSIONS Nephrin is localized in slit diaphragm in the matured glomeruli and is identical with mAb 5-1-6 antigen. Nephrin is involved in the development of proteinuria not only in mAb 5-1-6 nephropathy, but also in puromycin aminonucleoside nephropathy.

Abstract
The effects of traditional Chinese medicine (Sairei-to) on experimental glomerulonephritis induced in rats by monoclonal antibody (mAb) 1-22-3 injection was examined. The level of proteinuria in the Sairei-to-treated group was significantly lower than that in the PBS treated group. This suppressive effect was caused by the major component of Sairei-to, Syo-saiko-to but not by another component, Gorel-san. The suppressive effect of Syo-saiko-to was identified in its components (Bupleuri radix, Pinelliae tuber and Zingiberis rhizoma), but not in the other combined components (Ginseng radix and Zizyphi fructus). Further study revealed that the suppressive effects of the combined components were mainly derived from Bupleuri radix. It was demonstrated that the actual active ingredient is probably Saikosaponin-d. Light microscopy revealed that Sairei-to and its effective components suppressed the proliferation of mesangial cells and mesangial matrix expansion. Semiquantitative morphological studies of glomerular lesions on the eighth day showed that Syo-saiko-to and its combined components (Bupleuri radix, Zingiberis rhizoma and Pinelliae tuber) suppressed mesangial matrix expansion significantly compared with phosphate-buffered saline control groups (matrix score: 28.0 +/- 19.1 vs 102.3 +/- 14.1; 30.9 +/- 30.1 vs 102.3 +/- 14.1, P < 0.005, respectively). It was concluded that Saikosaponin-d, as well as Bupleuri radix, Syo-saiko-to and Sairei-to can suppress proteinuria and morphological changes in the rat glomerulonephritis model induced by mAb 1-22-3.
