Objective : This study was undertaken to determine if Juglandis Semen herbal acupuncture(Ja) has a protective effect against glycerol-induced acute renal failure in rats. Methods : Rats were dehydrated for 24hr and then injected with 5 ml/kg of 50 % glycerol, one-half of dose in each hindlimb muscle. In experiments for Ja effect, rats received 0.1 ml of Ja extraction in both sides of corresponding $Sh\grave{e}nsh\bar{u}(BL_{23})$ of human body and non-acupuncture points(the root of tail) for 3 days after injection of glycerol. The experimental group were divided into the Normal group, the Control group, the Ja to $Sh\grave{e}nsh\bar{u}(BL_{23})$ group(Ja-AS), the Ja to non-acupuncture points group(Ja-AN). Results : There were significant decrease of urine volume, BUN, fractional glucose excretion, fractional phosphate excretion, total protein level in Ja-AS as compared with the control group. Conclusion : This suggests that Ja-AS could be used in prevention and treatment of acute renal failure. However, the precise mechanisms of Ja protection remain to be determined.

Objective: This study was undertaken to evaluate the role of lipid peroxidation in oxidant-induced apoptosis and effect of JS on the apoptosis in opossum kidney (OK) cells, an established renal proximal tubular cells. Methods : Exposure of cells to 0.1mM tBHP for 2hr did not induce apoptosis, but subsequent incubation in normal culture medium for 18hr after tBHP treatment induced apoptotic cell death which is dependent of tBHP concentration. Results : JS decreased tBHP-induced apoptotic cell death in a dose-dependent fashion and at concentrations higher than 0.01 mg/ml completely prevented the apoptosis. tBHP-induced apoptosis was prevented by the lipid soluble antioxidant N,N'-diphenyl-p-phenylenediamine (DPPD) and water-soluble antioxidant Trolox. tBHP increased lipid peroxidation, which was inhibited by JS and DPPD. tBHP-induced DNA damage was prevented by JS and DPPD. Conclusion : These results indicate that tBHP induces apoptosis through a lipid peroxidation-dependent mechanism and JS exerts the protective effect against the apoptosis by preventing peroxidation of membrane lipids.

Scutellaria baicalensis Georgi. (SBGE) is known to be antioxidant effect. In addition of the effects, we further investigated the SBGE on the antioxidant effect on a renal cortical slices cell and kidney protecting effects. The results were as follows. 1 When renal cortical slices separated from a rabbit's kidney were treated with 1mM tert-Butylhydroperoxide (t-BHP) in the presence of SBGE. SBGE significant prevented t-BHP induced increase in lactate dehydrogenase (LDH) release and lipid peroxidation. 2. When renal cortical slices separated from a rabbit's kidney were treated with oxidant $300{\mu}M$ cisplatin in the presence of SBGE. SBGE significant prevented cisplatin-induced increase in LDH release and lipid peroxidation. 3. Pretreatment with 0.1g/kg SBGE for seven day and treatment with 5 mg/kg cisplatin by the intraperitoneal injection The results were that the pretreatment group with SBGE showed a significant decrease in lipid peroxidation, increase in clearance rate of blood urea nitrogen (BUN) and creatinine in the kidney than the administering single agent group of cisplatin. and pretreatment group with SBGE showed intact microvillus of proximal tubule and no contraction of rumen, it was a similar result with normal group. With the results SBGE showed to be highly effective on antioxidant effect and cellular protection activity against cisplatin that was a toxic agent on a kidney. Therefore, SBGE is considered to have protective effective on a disordered kidney or kidney diseases such as nephritis or renal failure that cause tissue damages in a kidney.

Inorganic arsenic (iAs) is a toxic metalloid found ubiquitously in the environment. In humans, exposure to iAs can result in toxicity and cause toxicological manifestations. Arsenic trioxide ($As_2O_3$) has been used in the treatment for acute promyelocytic leukemia. The kidney is the critical target organ of trivalent inorganic As ($iAs^{III}$) toxicity. We examine if oral administration of astaxanthin (AST) has protective effects on nephrotoxicity and oxidative stress induced by $As_2O_3$ exposure (via intraperitoneal injection) in rats. Markers of renal function, histopathological changes, $Na^+-K^+$ ATPase, sulfydryl, oxidative stress, and As accumulation in kidneys were evaluated as indicators of $As_2O_3$ exposure. AST showed a significant protective effect against $As_2O_3$-induced nephrotoxicity. These results suggest that the mechanisms of action, by which AST reduces nephrotoxicity, may include antioxidant protection against oxidative injury and reduction of As accumulation. These findings might be of therapeutic benefit in humans or animals suffering from exposure to $iAs^{III}$ from natural sources or cancer therapy.

Objectives: Cassia occidentalis L. is a weed belonging to the Caesalpiniaceae family. The root of this medicinal plant is used for the treatment of various ailments, including kidney diseases. The present study was aimed at evaluating the nephroprotective effects of HAE of the roots of Cassia occidentalis L. against gentamicininduced renal toxicity in albino Wistar rats. Methods: The renal toxicity was induced by subcutaneous administration of gentamicin at 100 mg/kg in the rats belonging to the disease control and treatment groups from the 4^th to the 8^th day. The rats in the treatment group received HAE of the roots of Cassia occidentalis L. at 67 mg/kg b. w. orally for 8 days, while no treatment was given to the rats in the disease control and plain control groups. At the end of the experiment, renal biomarkers viz; s. creatinine, b. urea, and s. uric acid, were investigated. The histopathological examination of the kidney specimens was also carried out. Results: The results of the present study revealed that renal function biomarkers such as s. creatinine, b. urea, and s. uric acid were significantly reduced in the rats of the treatment group as compared to those of the disease control group. Moreover, the histoarchitecture reports of the treatment group's kidney specimens showed significant improvements. Conclusion: The results suggested that the HAE of Cassia occidentalis L. roots promisingly prevented kidney injury in gentamicin-induced nephrotoxic rats. This effect might be due to improved clearance of gentamicin from the renal tubule and decreased generation of reactive oxygen species (ROS).

Curcumin (CMN) is known to have beneficial role in anorexia, coryza, cough, diabetic wounds, and hepatic disorders apart from its inherent antioxidant effects. Therefore, the present study was aimed to evaluate antioxidant effect of CMN in prevention of nephrolithiasis in rats-induced by ethylene glycol (EG) and Vitamin D3 (Vit. D3). Male Wistar rats (175 - 200 g) were randomized in groups like control, EG + Vit. D3 induced nephrolithiatiatic rats, CMN treated rats, CMN + EG + Vit. D3 treated rats, Vit. E + EG + Vit. D3 treated rats. Urine was collected weekly throughout the experimental protocol and estimated for calcium oxalate (CaO) count. After completion of experimental protocol serum was estimated for blood urea nitrogen and creatinine. Both the kidneys were excised and used to evaluate levels of biomarkers of oxidative stress and calcium oxalate crystal deposition by histopathological studies. Administration of EG and Vit. D3 to rats resulted in increased oxidative stress, hyperoxaluria and renal deposition of CaO crystals. Supplementation with CMN improves kidney function, reduces elevated oxidative stress, urinary oxalate level and renal deposition of CaO which shows its protective action in nephrolithiasis. The increased deposition of stone in the kidney and stone forming constituents of nephrolithiatic rats were effectively lowered by treatment of CMN.

Background: Renal-cell carcinoma (RCC) is resistant to almost all chemotherapeutics and radiation therapy. ${\beta}$-Elemene, a promising anticancer drug extracted from a traditional Chinese medicine, has been shown to be effective against various tumors. In the present study, anti-tumor effects on RCC cells and the involved mechanisms were investigated. Methods: Human RCC 786-0 cells were treated with different concentrations of ${\beta}$-elemene, and cell viability and apoptosis were measured by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay and flow cytometry, respectively. Protein expression was assayed by western blotting. Autophagy was evaluated by transmission electron microscopy. Results: ${\beta}$-Elemene inhibited the viability of 786-0 cells in a dose- and time-dependent manner. The anti-tumor effect was associated with induction of apoptosis. Further study showed that ${\beta}$-elemene inhibited the MAPK/ERK as well as PI3K/Akt/mTOR signalling pathways. Moreover, robust autophagy was observed in cells treated with ${\beta}$-elemene. Combined treatment of ${\beta}$-elemene with autophagy inhibitors 3-methyladenine or chlorochine significantly enhanced the anti-tumor effects. Conclusions: Our data provide first evidence that ${\beta}$-elemene can inhibit the proliferation of RCC 786-0 cells by inducing apoptosis as well as protective autophagy. The anti-tumor effect was associated with the inhibition of MAPK/ERK and PI3K/Akt/mTOR signalling pathway. Inhibition of autophagy might be a useful way to enhance the anti-tumor effect of ${\beta}$-elemene on 786-0 cells.

Background: The decreased renal function is known to be associated with biological aging, of which the main pathological features are chronic inflammation and renal interstitial fibrosis. In previous studies, we reported that total saponins from Panax japonicus (SPJs) can availably protect acute myocardial ischemia. We proposed that SPJs might have similar protective effects for aging-associated renal interstitial fibrosis. Thus, in the present study, we evaluated the overall effect of SPJs on renal fibrosis. Methods: Sprague-Dawley (SD) aging rats were given SPJs by gavage beginning from 18 months old, at 10 mg/kg/d and 60 mg/kg/d, up to 24 months old. After the experiment, changes in morphology, function and fibrosis of their kidneys were detected. The levels of serum uric acid (UA), β2-microglobulin (β2-MG) and cystatin C (Cys C) were assayed with ELISA kits. The levels of extracellular matrix (ECM), matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs), inflammatory factors and changes of oxidative stress parameters were examined. Results: After SPJs treatment, SD rats showed significantly histopathological changes in kidneys accompanied by decreased renal fibrosis and increased renal function; As compared with those in 3-month group, the levels of serum UA, Cys C and β2-MG in 24-month group were significantly increased (p < 0.05). Compared with those in the 24-month group, the levels of serum UA, Cys C and β2-MG in the SPJ-H group were significantly decreased. While ECM was reduced and the levels of MMP-2 and MMP-9 were increased, the levels of TIMP-1, TIMP-2 and transforming growth factor-β1 (TGF-β1)/Smad signaling were decreased; the expression level of phosphorylated nuclear factor kappa-B (NF-κB) was down-regulated with reduced inflammatory factors; meanwhile, the expression of nuclear factor erythroid 2-related factor 2-antioxidant response element (Nrf2-ARE) signaling was aggrandized. Conclusion: These results suggest that SPJs treatment can improve age-associated renal fibrosis by inhibiting TGF-β1/Smad, NFκB signaling pathways and activating Nrf2-ARE signaling pathways and that SPJs can be a potentially valuable anti-renal fibrosis drug.
