Abstract
A series of heteroleptic square-planar Pt and Pd complexes with bis(diisopropylphenyl) iminoacenaphtene (dpp-Bian) and Cl, 1,3-dithia-2-thione-4,5-dithiolate (dmit), or 1,3-dithia-2-thione-4,5-diselenolate (dsit) ligands have been prepared and characterized by spectroscopic techniques, elemental analysis, X-ray diffraction analysis, and cyclic voltammetry (CV). The intermolecular noncovalent interactions in the crystal structures were assessed by density functional theory (DFT) calculations. The anticancer activity of Pd complexes in breast cancer cell lines was limited by their solubility. Pd(dpp-Bian) complexes with dmit and dsit ligands as well as an uncoordinated dpp-Bian ligand were devoid of cytotoxicity, while the [Pd(dpp-Bian)Cl2] complex was cytotoxic. On the contrary, all Pt(dpp-Bian) complexes demonstrated anticancer activity in a low micromolar concentration range, which was 8-20 times higher than the activity of cisplatin, and up to 2.5-fold selectivity toward cancer cells over healthy fibroblasts. The presence of a redox-active dpp-Bian ligand in Pt and Pd complexes resulted in the induction of reactive oxygen species (ROS) in cancer cells. In addition, these complexes were able to intercalate into DNA, indicating the dual mechanism of action.

Abstract
Excessive cellular oxidative stress is widely perceived as a key factor in pathophysiological conditions and cancer development. Healthy cells use several mechanisms to maintain intracellular levels of reactive oxygen species (ROS) and overall redox homeostasis to avoid damage to DNA, proteins, and lipids. Cancer cells, in contrast, exhibit elevated ROS levels and upregulated protective antioxidant pathways. Counterintuitively, such elevated oxidative stress and enhanced antioxidant defence mechanisms in cancer cells provide a therapeutic opportunity for the development of drugs with different anticancer mechanisms of action (MoA). In this review, oxidative stress and the role of ROS in cells are described. The tumour-suppressive and tumour-promotive functions of ROS are discussed to compare these two different therapeutic strategies (increasing or decreasing ROS to fight cancer). Clinically approved drugs with demonstrated oxidative stress anticancer MoAs are highlighted before describing examples of metal-based anticancer drug candidates causing oxidative stress in cancer cells via novel MoAs.

Abstract
Cisplatin is a widely used chemotherapeutic agent. However, it is causing nephrotoxic side effects including a reduced glomerular filtration rate and acute kidney injury. Although kidneys can recover to an extent from the treatment, long-term damage is possible. While a lot of research is focusing on short-term effects, little is known about adverse metabolic effects in the process of recovery. In this study, male Han Wistar rats were dosed with a single intraperitoneal injection of 3 mg/kg cisplatin. Urine and kidney samples were harvested 3, 8 and 26 days after administration. Tubular injury was demonstrated through urinary biomarkers. Complementing this, mass spectrometry imaging gives insight on molecular alterations on a spatial level, thus making it well suited to analyze short- and long-term disturbances. Various metabolic pathways seem to be affected, as changes in a wide range of metabolites were observed between treated and control animals. Besides previously reported early changes in kidney metabolism, unprecedented long-term effects were detected including deviation in nucleotides, antioxidants, and phospholipids.

NHERF1 Loss Upregulates Enzymes of the Pentose Phosphate Pathway in Kidney Cortex. Antioxidants (Basel) 2020; 9:antiox9090862.

Abstract
(1) Background: We previously showed Na/H exchange regulatory factor 1 (NHERF1) loss resulted in increased susceptibility to cisplatin nephrotoxicity. NHERF1-deficient cultured proximal tubule cells and proximal tubules from NHERF1 knockout (KO) mice exhibit altered mitochondrial protein expression and poor survival. We hypothesized that NHERF1 loss results in changes in metabolic pathways and/or mitochondrial dysfunction, leading to increased sensitivity to cisplatin nephrotoxicity. (2) Methods: Two to 4-month-old male wildtype (WT) and KO mice were treated with vehicle or cisplatin (20 mg/kg dose IP). After 72 h, kidney cortex homogenates were utilized for metabolic enzyme activities. Non-treated kidneys were used to isolate mitochondria for mitochondrial respiration via the Seahorse XF24 analyzer. Non-treated kidneys were also used for LC-MS analysis to evaluate kidney ATP abundance, and electron microscopy (EM) was utilized to evaluate mitochondrial morphology and number. (3) Results: KO mouse kidneys exhibit significant increases in malic enzyme and glucose-6 phosphate dehydrogenase activity under baseline conditions but in no other gluconeogenic or glycolytic enzymes. NHERF1 loss does not decrease kidney ATP content. Mitochondrial morphology, number, and area appeared normal. Isolated mitochondria function was similar between WT and KO. Conclusions: KO kidneys experience a shift in metabolism to the pentose phosphate pathway, which may sensitize them to the oxidative stress imposed by cisplatin.

Abstract
The effects of a widely used antitumour drug, cisplatin, on freshly isolated porcine proximal tubular cells (PPTC) in suspension were investigated. Incubation of the PPTC with 5-500μM cisplatin resulted in a decrease in mitochondrial membrane potential (MMP) and in cell death. In addition, the formation of reactive oxygen species (ROS) was observed within 20 minutes. Prevention of ROS formation with the antioxidants diphenyl- p-phenylene-diamine (DPPD) or desferrioxamine had no effect on the cisplatin-induced effects on MMP and cell death, implying that cisplatin-induced ROS formation is not a cause of cell death. In order to investigate whether the ROS formation was related to mitochondrial damage, we determined the effects of cisplatin on the enzymatic activities of NADP:ubiquinone reductase (Complex I) and succinate:ubiquinone reductase (Complex II) of the respiratory chain. Exposure of the PPTC to cisplatin resulted in a time-dependent and dose-dependent inhibition of the activities of both Complex I and Complex II. The inhibition of these activities and the depletion of ATP could not be prevented by the antioxidants, indicating that these effects are not a consequence of ROS formation. We propose that damage to the mitochondria could be a key event in cisplatin-induced cell death.

Abstract
Cisplatin is a widely used antineoplastic agent for the treatment of metastatic tumors, advanced bladder cancer and many other solid tumors. However, at higher doses, toxicities such as nephrotoxicity may appear. Cisplatin leads to DNA damage and subsequently renal cell death. Besides that, oxidative stress is also implicated as one of the main causes of nephrotoxicity. Several studies showed that numerous natural products: ginseng, curcumin, licorice, honey and pomegranate were able to reduce the oxidative stress by restoring the levels of antioxidant enzymes and also at the same time act as an anti-inflammatory agent. Furthermore, pre-treatment with vitamin supplementation, such as vitamin C, E and riboflavin markedly decreased serum urea and increased the levels of antioxidant enzymes in the kidney even after cisplatin induction in cancer patients. These natural products possess potent antioxidant and anti-inflammatory medicinal properties, and they can be safely used as a supplementary regime or combination therapy against cisplatin-induced nephrotoxicity. The present review focused on the protective role of a few natural products which is widely used in folk medicines in cisplatin-induced nephrotoxicity.

Abstract
Cisplatin is one of the highly consumed and effective antitumor agents whose clinical application is accompanied by nephrotoxicity adverse reaction. Also, other complications such as ototoxicity and hepatotoxicity are a matter of concern. Today, it is suggested that cisplatin-associated toxicities are mainly induced by free radicals production, which will result in oxidative organ injury. The evidence is growing over the protective effects of antioxidants on cisplatin-induced adverse reactions especially nephrotoxicity. The possible protective effects of vitamin E and its derivative in cisplatin-induced nephrotoxicity and ototoxicity are reviewed here at the light of pertinent results from basic and clinical research. Administration of vitamin E alone or in combination with other antioxidant agents could cause amelioration in oxidative stress biomarkers such as decreasing the level of malondialdehyde, reducing serum urea and creatinine, and also enhancing the activities of renal antioxidant enzymes including renal catalase, glutathione-S-transferase, and superoxide dismutase. Although the data from most of the studies are in favors of protective effects of vitamin E against cisplatin-induced toxicity, more clinical trials are needed to clarify the clinical importance of vitamin E administration as an antioxidant during cisplatin therapy in cancer condition.

Abstract
Cisplatin (CP) is one of the most important anticancer compounds with its therapeutic usefulness in diverse types of solid cancer. However, its use is limited due to nephrotoxicity induced by it. Oxidative stress is an effective participant which contributes actively to pathogenesis of CP-induced nephrotoxicity. Nanoparticle form of a rare earth metal cerium, also known as nanoceria (NC), has come up as a potential antioxidant and anti-inflammatory agent. In the present study, administration of CP in Swiss mice resulted in reduction of body weight, increased oxidative stress and pro-inflammatory cytokine levels including IL-6 and TNF-α along with alteration in normal histological architecture of kidney. On the contrary, NC (0.2 and 2 mg/kg i.p.) ameliorated nephrotoxicity of CP which was evident by reduction in levels of renal injury markers in plasma, i.e., creatinine and blood urea nitrogen. NC ameliorated oxidative stress by showing a reduction in levels of malondialdehyde and increased levels of endogenous antioxidants reduced glutathione and catalase. Further, NC treatment also reduced the levels of pro-inflammatory cytokines. Furthermore, protective effect of NC was also corroborated by histopathological studies wherein, kidneys from CP group showed altered tissue structure after acute as well as chronic exposure of CP while the tissues from treated groups showed absence of alterations in kidney histology. The results from present study suggested that oxidative stress and pro-inflammatory cytokines play a central role in pathogenesis of CP-induced nephrotoxicity and NC provides protection from CP-induced nephrotoxicity due to its antioxidant and anti-inflammatory properties.

Abstract
Herbal tea kinkéliba prepared from the leaves of Combretum micranthum has been widely consumed in West African countries for its flavor, nutritional and medicinal properties. Under bio-guided screening, the kinkéliba leaves were chemically investigated using various chromatographic and spectrometric methods that led to the identification of thirteen different flavonoid compounds. Further biological tests illustrated that the identified compounds may have synergistic effects to decrease the expression of phosphoenolpyruvate carboxykinase (PEPCK) mRNA and glucose production in an H4IIE hepatoma cell line, indicating its potential use for insulin-resistant diabetes treatment. Further in vivo study on C57BL/6J mice indicates that kinkéliba can lower plasma glucose levels in a dose-dependent manner without significant weight loss and toxicity. The ethyl acetate extract in rich of flavonoids could also increase the glucose tolerance (GT) after seven weeks' administrations. Both in vitro and in vivo experiments support a potential new application of kinkéliba leaves as an anti-diabetes agent.

Abstract
Cisplatin is one of the most effective chemotherapeutic agents against various types of cancers; however, it is also associated with nephrotoxicity. Recently, it was reported that inflammatory mechanisms play a key role in the development of nephrotoxicity. Epoxyeicosatrienoic acids (EETs) have an anti-inflammatory effect and are metabolized by soluble epoxide hydrolase (sEH: encoded by EPHX2 gene). Here, we determined the change in sEH activity and EPHX2 expression in renal tissue associated with the development of cisplatin-induced nephrotoxicity. Cisplatin administration decreased hydrolase activity accompanied by down-regulation of sEH and EPHX2 expression. The down-regulation occurred prior to the elevation of blood urea nitrogen (BUN) and tumor necrosis factor-α (TNF-α) gene expression or at treatment with low dose cisplatin. In addition, a negative correlation was found between EPHX2 expression and renal thiobarbituric acid reactive substance (TBARS), and edaravone, a radical scavenger, administration did not down-regulate expression of this gene. The results of this study suggest that cisplatin decreased sEH activity through the down-regulation of sEH and EPHX2 expression, and this down-regulation was involved in a negative feedback loop to protect renal tissue from further damage. Thus, sEH is a potential therapeutic target of cisplatin-induced nephrotoxicity.

Abstract
OBJECTIVE To study the potential nephroprotective role of agomelatine in rat renal tissue in cases of contrast-induced nephrotoxicity (CIN). The drug's action on the antioxidant system and proinflammatory cytokines, superoxide dismutase (SOD) activity, levels of glutathione (GSH) and malondialdehyde (MDA) and the gene expression of interleukin-6 (IL-6), tumour necrosis factor (TNF)-α and nuclear factor kappa B (NF-κB) was measured. Tubular necrosis and hyaline and haemorrhagic casts were also histopathologically evaluated. METHODS The institutional ethics and local animal care committees approved the study. Eight groups of six rats were put on the following drug regimens: Group 1: healthy controls, Group 2: GLY (glycerol), Group 3: CM (contrast media--iohexol 10 ml kg(-1)), Group 4: GLY+CM, Group 5: CM+AGO20 (agomelatine 20 mg kg(-1)), Group 6: GLY+CM+AGO20, Group 7: CM+AGO40 (agomelatine 40 mg kg(-1)) and Group 8: GLY+CM+AGO40. The groups were evaluated by one-way analysis of variance and Duncan's multiple comparison test. RESULTS Agomelatine administration significantly improved the serum levels of blood urea nitrogen (BUN) and creatinine, SOD activity, GSH and MDA. The use of agomelatine had substantial downregulatory consequences on TNF-α, NF-κB and IL-6 messenger RNA levels. Mild-to-severe hyaline and haemorrhagic casts and tubular necrosis were observed in all groups, except in the healthy group. The histopathological scores were better in the agomelatine treatment groups. CONCLUSION Agomelatine has nephroprotective effects against CIN in rats. This effect can be attributed to its properties of reducing oxidative stress and inhibiting the secretion of proinflammatory cytokines (NF-κB, TNF-α and IL-6). ADVANCES IN KNOWLEDGE CIN is one of the most important adverse effects of radiological procedures. Renal failure, diabetes, malignancy, old age and non-steroidal anti-inflammatory drug use pose the risk of CIN in patients. Several clinical studies have investigated ways to avoid CIN. Theophylline/aminophylline, statins, ascorbic acid and iloprost have been suggested for this purpose. Agomelatine is one of the melatonin ligands and is used for affective disorders and has antioxidant features. In this study, we hypothesized that agomelatine could have nephroprotective, antioxidant and anti-inflammatory effects against CIN in rats.

Abstract
Background: The function of renin angiotensin system (RAS) is gender-related, and this system affects cisplatin (CP)-induced nephrotoxicity. In this study, we compared the effect of enalapril as an angiotensin-converting enzyme (ACE) inhibitor on CP-induced nephrotoxicity between male and female rats. Materials and Methods: Sixty-two adult male and female Wistar rats were divided into eight groups. Both genders received CP (2.5 mg/kg, i.p.) and enalapril (30 mg/kg, i.p.) for 7 days in compared with CP alone or enalapril alone or vehicle alone treated groups. At the end of the experiment, blood samples were obtained, and the kidney tissue was investigated for histopathological changes. Results: CP increased the serum levels of blood urea nitrogen and creatinine as well as kidney weight and kidney tissue damage score in both genders (P < 0.05). However, not only enalapril failed to ameliorate the aforementioned parameters in both genders, but also it intensified nephrotoxicity in females (P < 0.05). In addition, enalapril enhanced body weight loss induced by CP in females (P < 0.05). CP alone decreased kidney level of nitrite in both genders (P < 0.05) and enalapril could not reverse this decreasing. The combination of enalapril and CP significantly increased serum level of nitrite in females, but this was not observed in males (P < 0.05). Conclusion: Enalapril as an ACE inhibitor failed to ameliorate nephrotoxicity induced by CP in both male and female rats. In addition, enalapril aggravated CP-induced nephrotoxicity in female possibly due to gender-dependent RAS response.

Abstract
PPAR gamma was a key nuclear receptor, playing an important role in the immune defense and the anti-inflammatory mechanism. In this study, the full-length PPAR gamma (EcPPAR gamma) was obtained, containing a 5'UTR of 133 bp, an ORF of 1602 bp and a 3'UTR of 26 bp besides the poly (A) tail. The EcPPAR gamma gene encoded a protein of 533 amino acids with an estimated molecular mass of 60.02 KDa and a predicted isoelectric point (pI) of 6.26. The deduced amino acid sequence showed that EcPPAR gamma consisted of the conserved residues and the domains known to be critical for the PPAR gamma function. The quantitative real-time PCR analysis revealed that EcPPAR gamma transcript was expressed in all the examined tissue, while the strong expression was observed in intestine, followed by the expression in liver, gill, spleen heart, kidney and muscle. Vibrio challenge could stimulate the inflammatory response in grouper and induce a sharp increase of pro-inflammatory cytokines expression, lipid peroxidation and DNA damage, while the up-regulation of vibrio-induced inflammation could also increase the non-specific immune defense. The groupers challenged with Vibrio alginolyticus showed a sharp increase of EcPPAR gamma transcript in immune tissues. Subcellular localization analysis revealed that EcPPAR gamma was distributed in the nucleus. Furthermore, overexpression of EcPPAR gamma could down-regulated the expression of IL1b, IL6, TNF1 and TNF2. In addition, the administration of PPAR gamma antagonist, GW9662, could up-regulate the expression of pro-inflammatory genes, including IL1b, IL6, TNF1 and TNF2. Together, these results indicated that EcPPAR gamma serving as a negative regulator of pro-inflammatory cytokines may play an important role in the immune defense against vibrio-induced inflammation in grouper.

Abstract
The aim of the present study was to evaluate the possible protective effect of polydatin (PD) on cisplatin (Cis) induced oxidative stress in rats. Totally, thirty male Wistar albino rats were fed standard rodent diet and divided into 5 equal groups: the control group (vehicle treated) was treated with physiological saline for ten days both orally and intraperitoneally (i.p.), the second group was orally treated with physiological saline and 7 mg/kg single i.p. injection of Cis on the seventh day, and third, fourth, and fifth groups were treated orally PD at 25, 50, and 100 mg/kg/day, respectively for 10 days starting seven days before Cis injection and 7 mg/kg single i.p. Cis was injected on the seventh day. Cis resulted in significant increase malondialdehyde levels and decreased glutathione levels. In addition, Cis treatment decreased superoxide dismutase and catalase activities in erythrocyte and tissues. Also, Cis treatment caused to increase DNA damage and affected serum biochemical parameters whereas slightly decreased AchE activity. However, treatment of PD resulted in reversal of Cis-induced oxidative stress, lipid peroxidation, and activities of antioxidant enzymes. In conclusion, PD has protective effect in rats against Cis-induced oxidative stress, enhances antioxidant defence mechanism, and regenerates their tissues.

Abstract
OBJECTIVE The aim of the present study was to evaluate the nephroprotective effect of methanolic extract of Heliotropium eichwaldii (MHE) in mice with cisplatin-induced acute renal damage. METHODS Nephrotoxicity was induced by a single intraperitoneal injection of cisplatin (16mg/kg). Swiss albino mice were injected with vehicle, cisplatin, cisplatin plus MHE 200 mg/kg and cisplatin plus MHE 400mg/kg, respectively. MHE was administered for 7 d at a dose of 200 and 400 mg/kg per day orally starting 4 d before cisplatin injection. Animals were sacrificed 3d after treatment and blood as well as kidney tissue was isolated and analyzed. The various parameters such as blood urea nitrogen (BUN), serum creatinine (CRE), malondialdehyde (MDA), and catalase (CAT) and superoxide dismutase (SOD) activities were analyzed. RESULTS MHE treatment significantly reduced BUN and serum CRE levels elevated by cisplatin administration (P<0.05). Also, it significantly attenuated cisplatin-induced increase in MDA level and improved the decreased CAT and SOD activities in renal cortical homogenates (P<0.05). Additionally, histopathological examination and scoring showed that MHE markedly ameliorated cisplatin-induced renal tubular necrosis. CONCLUSION MHE can be considered a potential candidate for protection of nephrotoxicity induced by cisplatin.

Abstract
The protective effects of procaine on cisplatin-induced kidney damage were studied with rat renal cortical slices in vitro. Cisplatin (2 mm) increased the leakage of the enzymes N-acetyl-beta-d-glucosaminidase, aspartate aminotransferase and lactate dehydrogenase from the slices into the incubation medium five-fold, 10-fold and 11-fold, respectively. Procaine (2 mm) protected against this cellular damage and decreased the leakage to 50, 65 and 29% of that caused by cisplatin. Protection was also observed when the slices were treated with two metabolites of procaine [diethylaminoethanol (DEAE) and p-aminobenzoic acid (PABA)], although these were slightly less effective than procaine. Cisplatin also increased mitochondrial lipid peroxidation to 177% of controls, and procaine, DEAE and PABA inhibited this cisplatin-induced increase by 24, 30 and 22%, respectively. Procaine, DEAE and PABA had no effects, however, on either the loss of mitochondrial protein-sulfhydryls or the decrease of Ca(2+) uptake by the mitochondria that were caused by cisplatin. These observations suggest that the protection by procaine and its metabolites results from their inhibitory activity on the mitochondrial lipid peroxidation that was induced by cisplatin.

Abstract
Cells require tight regulation of the intracellular redox balance and consequently of reactive oxygen species for proper redox signaling and maintenance of metal (e.g., of iron and copper) homeostasis. In several diseases, including cancer, this balance is disturbed. Therefore, anticancer drugs targeting the redox systems, for example, glutathione and thioredoxin, have entered focus of interest. Anticancer metal complexes (platinum, gold, arsenic, ruthenium, rhodium, copper, vanadium, cobalt, manganese, gadolinium, and molybdenum) have been shown to strongly interact with or even disturb cellular redox homeostasis. In this context, especially the hypothesis of "activation by reduction" as well as the "hard and soft acids and bases" theory with respect to coordination of metal ions to cellular ligands represent important concepts to understand the molecular modes of action of anticancer metal drugs. The aim of this review is to highlight specific interactions of metal-based anticancer drugs with the cellular redox homeostasis and to explain this behavior by considering chemical properties of the respective anticancer metal complexes currently either in (pre)clinical development or in daily clinical routine in oncology.

Abstract
BACKGROUND Cisplatin (CP)-induced kidney damage and effects of DL-buthionine-(S,R)-sulfoximine (BSO) on it are species- and age-different. It remains unclear whether CP-induced cytotoxicity in renal proximal tubular epithelial cells (RTEC), the main target cells of CP, is also species- and age-different; and whether CP-induced cytotoxicity varies with the difference in age and species, if any, is one of the questions. In the present study, the effects of BSO on CP-induced cytotoxicity in primary cultures of RTEC isolated from monkeys and different age and sex rats were studied. METHODS The RTEC were isolated from 3-week-old, 2-month-old, or 5-month-old rats, and 6-8 year-old monkeys. After subculturing, RTEC was inoculated into type I collagen-coated 96-well culture plates; after preincubation, 40 microM BSO was added, 16 hours later, varying concentrations of CP were added. At that time, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assays were performed to test cell viability. RESULTS The concentrations of CP that inhibited 50% cell growth (IC50) of RTEC from rats and monkeys were 1.11 and 3.03 mM at 8 hours, and 0.51 and 1.24 mM at 24 hours, respectively. The BSO made the IC50s of RTEC from rats and monkeys lower, down to 0.07 and 0.48 mM at 8 hours, and 0.02 and 0.11 mM at 24 hours, respectively. The IC50s of RTEC from different sex and age rats were almost same. CONCLUSION These results suggested that CP-induced cytotoxicity was concentration- and time-dependent, with species-dependent differences, rat RTEC were more susceptible to CP than monkey RTEC, rat RTEC were more dependent on glutathione (GSH) during the stress state were than monkey cells; CP-induced cytotoxicity was without sex- and age-dependent differences in rat RTEC.

Abstract
Pentoxifylline (PTX) has been reported to inhibit TNF-alpha production and prevent several types of acute renal failure. This study was undertaken to determine the effect of PTX on the cisplatin-induced acute renal failure in rabbits. Rabbits received a single injection of cisplatin (5 mg/kg, i.p.) with or without PTX pretreatment (30 mg/kg, i.v.). Alterations in renal function, apoptotic cell death, and TNF-alpha mRNA expression were measured at 24 or 48 h after cisplatin injection. Cisplatin caused an increase in BUN and serum creatinine levels, a reduction in GFR, and an increase in fractional Na+ excretion. Such changes were significantly attenuated by PTX pretreatment (30 mg/kg, i.p.) 30 min before and 24 h after cisplatin injection. Morphological evaluation showed that cisplatin injection induced diffuse proximal tubular necrosis and the effect was reduced by PTX pretreatment. Cisplatin induced apoptotic cell death in renal cortex and the effect was significantly prevented by PTX. Treatment of opossum kidney cells with cisplatin resulted in cell death, which was significantly prevented by PTX. The increase in lipid peroxidation and the decrease in renal blood flow induced by cisplatin were not affected by PTX. The expression of TNF-alpha mRNA was increased after cisplatin injection and the effect was inhibited by PTX pretreatment. These results suggest that cisplatin-induced acute renal failure in rabbits is associated with an induction of TNF-alpha-mediated apoptosis, and that PTX may exert a protective effect against cisplatin nephrotoxicity by inhibiting TNF-alpha production.

Abstract
The main purpose of this review is to update and analyze the effect of several antineoplastic drugs (adriamycin, apoptodilin, casiopeinas, cisplatin, clotrimazole, cyclophosphamide, ditercalinium, NSAIDs, tamoxifen, taxol, 6-mercaptopurine, and alpha-tocopheryl succinate) and energy metabolism inhibitors (2-DOG, gossypol, delocalized lipophilic cations, and uncouplers) on tumor development and progression. The possibility that these antineoplastic drugs currently used in in vitro cancer models, in chemo-therapy, or under study in phase I to III clinical trials induce tumor cellular death by altering also metabolite concentration (i.e., ATP), enzyme activities, and/or energy metabolism fluxes is assessed. It is proposed that the use of energy metabolic therapy, as an alternative or complementary strategy, might be a promising novel approach in the treatment of cancer.

Abstract
Cisplatin-induced oxidative stress can cause liver and kidney damage, thus limiting therapeutic efficacy. Thus, in the present study, since Rhus verniciflua Stokes (RVS) containing flavonoids has antioxidant effects, we investigated whether it can protect cisplatin-induced toxicity in vitro and in vivo, The in vitro effects of RVS on the cell viability and reactive oxygen species (ROS) production were investigated using cisplatin-treated Madin-Darby Canine kidney (MDCK)-I renal cells. Its in vivo effects were also studied in BALB/c mice inoculated with CT-26 colon adenocarcinoma cells and treated with cisplatin with or without RVS. Liver and renal functions were assessed together with indices of tissue oxidation. RVS prevented cisplatin-induced cytotoxicity and ROS release against MDCK-I cells. RVS alone exerted modest antitumor activity against CT-26 cells. When used concurrently with cisplatin, RVS prevented the increases in serum blood urea nitrogen (BUN), creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and NO, while reducing liver and kidney tissue MDA content, and increasing catalase, glutathione (GSH), and superoxide dismutase (SOD) activities. Moreover, the antitumor efficacy of cisplatin was not altered by concurrent administration of RVS. These findings demonstrate that RVS prevents cisplatin-induced toxicity in vitro and in vivo via an antioxidant activity without hurting its antitumor effectiveness, suggesting that RVS can be usefully applied to the neoplastic patients as a combined chemopreventive agent with cisplatin.

Abstract
The aim of this study was to determine the effect of bicyclol against cisplatin-induced hepatotoxicity and the influence on the antitumour capacity of cisplatin in hepatocarcinoma 22 (H22) tumour-bearing mice. ICR mice were treated with bicyclol (250 mg/kg, orally) 2 hr before the injection of cisplatin (5 mg/kg, intraperitoneally) for 5 days (once daily) after H22 tumour cells were implanted. All animals were killed on the fifth day after cisplatin treatment and tumour weight of each animal was measured. Liver pathological changes were examined by light microscopy and biochemical assay. The expressions of liver inducible nitric oxide synthase (iNOS and nitric oxide synthase 2) and 3-nitrotyrosine were assessed by Western blotting. Bicyclol showed a significant protection as evidenced by the decrease of elevated serum aminotransferases and lactate dehydrogenase, and improvement of histopathological injury induced by cisplatin. The formation of liver malondialdehyde with a concomitant reduction of reduced glutathione was also inhibited by bicyclol, while the activities of liver superoxide dismutase, catalase and glutathione peroxidase were all increased, respectively. In addition, the over expressions of liver iNOS and 3-nitrotyrosine were suppressed by bicyclol. The administration of bicyclol had no affect on the anti-tumour capacity of cisplatin in mice bearing H22 tumour. The hepatoprotective action of bicyclol provides a new approach for preventing the hepatotoxicity induced by cisplatin in the clinic.

Abstract
Targeted therapeutics are aimed to hit one or a few key cellular targets. Agents that target single signaling molecules (such as EGFR and IGF-R1) often show limited clinical activities, at least in the major groups of solid tumors. Nevertheless, some signaling inhibitors are effective in the treatment of previously difficult-to-treat diseases such as renal carcinoma. Similarly, these drugs inhibit multiple kinases and/or may display off-target activities. Inhibition of cellular targets such as the proteasome, heat-shock protein 90, and histone deacetylase induces complex cellular effects, and agents that inhibit these targets show promising clinical activities. Clinically effective targeted agents are therefore reminiscent of conventional agents such as cisplatin and doxorubicin, which are known to have several cellular targets. It is becoming increasingly clear that a comprehensive understanding of the spectrum of effects exerted by an anticancer agent is fundamental for understanding its efficacy and toxicity profile.

Abstract
In this study, the antioxidant effect of aminoguanidine on nephrotoxicity of a single dose of cisplatin is investigated and compared with the effects of well-known antioxidants vitamin C and E combination. Tubular damage and perivascular inflammation were observed in kidney samples of the cisplatin-administered groups. Aminoguanidine and vitamin C-E combination are found to be capable of preventing these effects of cisplatin. Liver tissues of all groups were intact. Cisplatin-induced oxidative stress was evidenced by significant decrease in glutathione and significant increase in malondialdehyde levels in kidney samples. Antioxidants with cisplatin decreased malondialdehyde levels. Antioxidants with cisplatin prevented the decrease in liver glutathione levels. The nephrotoxicity was confirmed biochemically by significant elevation of serum urea and creatinine levels. Both vitamin C-E combination and aminoguanidine prevented the increase in serum urea levels according to the cisplatin group.

Abstract
Cisplatin is commonly used for the treatment of several solid tumors. However, its clinical use is often limited by renal toxicity. The indirect antioxidant 3H-1,2-dithiole-3-thione (D3T) has been known to protect cells from oxidative damage by up-regulating the expression of antioxidative genes through the transcription factor NF-E2-related factor 2 (Nrf2) pathway. We hypothesized that D3T treatment may be protective against cisplatin-induced nephrotoxicity by enhancing the antioxidative capacity of renal cells. In cultured murine tubular epithelial cells, D3T facilitates the nuclear accumulation of Nrf2 and the subsequent expression of its target genes such as glutamate cysteine ligase (GCL). Increased GSH pool in D3T-treated renal cells appears to be associated with amelioration of cisplatin-mediated cell death. Protective effects of D3T were also observed in mice. Oral administration of D3T (0.25mmol/kg) increased the expression of GCL in mouse kidney, which resulted in suppression of cisplatin-mediated increases in blood urea nitrogen and serum creatinine. Histopathological changes representing cisplatin-induced acute renal failure were also effectively ameliorated by D3T treatment. Collectively, these results indicate that pharmacological activation of the Nrf2 pathway might have a beneficial effect on reducing chemotherapy-associated cytotoxic adverse effects.

Abstract
In a previous study, E47 HepG2 cells that overexpress human CYP2E1 were shown to be more sensitive to cisplatin than C34 cells that do not express CYP2E1. In this study, we found that this sensitivity was due to an earlier activation of ERK in the E47 cells compared to the C34 cells. Glutathione depletion by L-buthionine sulfoximine (BSO) enhanced cisplatin cytotoxicity via increasing production of reactive oxygen species (ROS) and activation of ERK. In contrast, elevation of glutathione by glutathione ethyl ester (GSHE) decreased cisplatin/BSO cytotoxicity by decreasing ROS production and ERK activation. Inhibition of ERK activation by U0126 protected against cisplatin/BSO cytotoxicity via inhibiting ROS production but not restoring intracellular glutathione content. Examination of the mode of cell death showed that U0126 inhibited cisplatin-induced necrosis but not apoptosis. Cisplatin-induced apoptosis was caspases-dependent; BSO switched cisplatin-induced apoptosis to necrosis via decreasing activity of caspases, and GSHE switched cisplatin/BSO-induced necrosis back to apoptosis through maintaining activity of caspases. Similar to GSHE, U0126 partially switched cisplatin/BSO induced necrosis to apoptosis via restoring activity of caspases. Cisplatin lowered levels of thioredoxin, especially in the presence of BSO. Although U0126 failed in restoring intracellular glutathione levels, it restored thioredoxin levels, which maintain the activity of the caspases. These results suggest that thioredoxin can replace glutathione to promote the active thiol redox state necessary for caspase activity, and thus glutathione and thioredoxin regulate the mode of cisplatin toxicity in E47 cells via redox regulation of caspase activity.

Abstract
Cisplatin is a widely used antineoplastic agent that exhibits dose limiting nephrotoxicity. We have previously shown that the administration of cisplatin results in decrease in the activities of renal brush border membrane (BBM) enzymes and transport of inorganic phosphate (Pi) across BBM vesicles. In the present study we have investigated the effect of pre-treatment with vitamin C (ascorbic acid) on cisplatin-induced nephrotoxicity and changes in BBM enzymes and Pi transport. Administration of a single dose of cisplatin (6 mg/kg body weight) caused nephrotoxicity in rats that manifested biochemically as an elevation of serum urea nitrogen and creatinine levels. Treatment of rats with a single dose of vitamin C, six hours prior to administration of cisplatin, protected the kidney from the damaging effect of cisplatin. Vitamin C pre-treatment significantly decreased the urea nitrogen and creatinine levels. It attenuated the cisplatin-induced reduction in the activities of BBM and anti-oxidant enzymes and also Pi transport. These results suggest that vitamin C is an effective chemoprotectant against cisplatin-induced acute renal failure and dysfunction of the renal BBM in rats.

Abstract
Utilizaram-se 12 cães, machos, distribuídos em quatro grupos (G) experimentais, selecionados de acordo com o tempo de fluidoterapia com solução fisiológica 0,9%: G1 (sem fluidoterapia), G2 (uma hora de fluidoterapia antes da cisplatina), G3 (uma hora de fluidoterapia antes da cisplatina e uma hora após) e G4 (duas horas de fluidoterapia antes da cisplatina e uma após). Todos os animais receberam a cisplatina (70mg/m²), pela via intravenosa, sendo os ciclos de quimioterapia realizados em intervalos de três semanas, num total de três ciclos. O ondansetron (0,4mg/kg) foi administrado pela via intravenosa, a cada oito horas, no dia da quimioterapia e, a seguir, a cada 12 horas, por dois dias. O methimazole (40mg/kg) foi pela via oral, 30 minutos antes da cisplatina e quatro horas após. Avaliaram-se os parâmetros hematológicos, bioquímicos, urinários e dosagem de tiroxina e triiodotironina a cada sete dias até o término do experimento. Esse protocolo foi eficaz e seguro em cães que permaneceram sob fluidoterapia durante duas a três horas. Os animais que não receberam fluidoterapia e os que ficaram somente uma hora sob infusão intravenosa de solução fisiológica apresentaram alterações que resultaram em não-recomendação do protocolo.

Abstract
Statins have anti-inflammatory effects that are not directly related to their cholesterol-lowering activity. This study aimed to investigate the effect of simvastatin on the extent of tissue damage in cisplatin-induced nephrotoxicity and hepatotoxicity. The rats received a single intravenous injection of 2.5mgkg(-1) cisplatin. Other groups received either simvastatin (1mgkg(-1)) or the vehicle (ethanol:saline) intraperitoneally for 10 days beginning 5 days prior to cisplatin injection. All animals were decapitated 5 days after cisplatin administration. Trunk blood was collected and analyzed for blood urea nitrogen (BUN), creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), albumin, and total bilirubin levels. The urine samples were used for the calculation of creatinine clearance levels. The kidney and liver samples were stored for the measurement of malondialdehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO) activity and collagen content or were processed for histopathological examinations. Formation of reactive oxygen species in tissue samples was monitored by using chemiluminescence method. Simvastation reduced the extent of both kidney and liver damage and preserved both kidney and liver functions (p<0.01-0.001). Increase in liver MDA level with a concomitant reduction in GSH in the cisplatin group was attenuated by simvastatin treatment (p<0.05-0.01). Increase in tissue collagen content and chemiluminescence levels in the kidney and liver samples of the cisplatin group was also reversed by simvastatin (p<0.001). In conclusion, simvastatin is beneficial in cisplatin-induced kidney and liver dysfunction and organ damage in rats via prevention of lipid peroxidation and tissue fibrosis, preservation of antioxidant glutathione, and suppression of neutrophil infiltration.

Abstract
Bacillus anthracis lethal toxin (LT) produces symptoms of anthrax in mice and induces rapid lysis of macrophages derived from certain inbred strains. LT is comprised of a receptor binding component, protective antigen (PA), which delivers the enzymatic component, lethal factor (LF), into cells. We found that mouse macrophages were protected from toxin by the antitumor drug cis-diammineplatinum (II) dichloride (cisplatin). Cisplatin was shown to inhibit LT-mediated cleavage of cellular mitogen-activated protein kinases (MEKs) without inhibiting LF's in vitro proteolytic activity. Cisplatin-treated PA lost 100% of its ability to function in toxicity assays when paired with untreated LF, despite maintaining the ability to bind to cells. Cisplatin-treated PA was unable to form heptameric oligomers required for LF binding and translocation. The drug was shown to modify PA in a reversible noncovalent manner. Not surprisingly, cisplatin also blocked the actions of anthrax edema toxin and of LF-Pseudomonas aeruginosa exotoxin A fusion peptide (FP59), both of which require PA for translocation. Treatment of BALB/cJ mice or Fischer F344 rats with cisplatin at biologically relevant concentrations completely protected the animals from a coadministered lethal dose of LT. However, treatment with cisplatin 2 hours before or after animals received a lethal bolus of toxin did not protect them.

Abstract
Infusion of contrast agents increases osmotic load, viscosity, hypoxemia of the renal medulla and renal free radical production through post-ischemic oxidative stress. The present experimental study sought to determine whether melatonin, because of its anti-oxidant properties might have a preventive and protective role against the development of contrast-induced nephropathy (CIN). Twenty-four adult male rats were divided into four experimental groups: healthy control rats (CR), rats with CIN (CINR), rats with CIN pretreated with melatonin (CINR1M), and rats with CIN pre- and post-treated with melatonin (CINR2M). In CINR, both serum creatinine (Cr) level and fractional excretion of sodium (FE-Na) significantly increased, whereas Cr clearance decreased at post-CIN compared with pre-CIN period. Rats in CINR1M did not show any improvement in renal function. Cr clearance decreased, whereas both serum Cr level and FE-Na increased in rats pretreated with melatonin. In contrast, significant improvements were observed in CINR2M. Serum Cr and Cr clearance did not change, whereas FE-Na significantly reduced in rats pre- and post-treated with melatonin. In conclusion, the present experimental study clearly demonstrated the preventive and protective role of melatonin against the development of CIN.

Abstract
BACKGROUND Grape-seed (Vitis spp.) extract (GSE) is a widely used antioxidant dietary supplement. Chemotherapeutic agents such as cisplatin induce oxidative damage in the gastrointestinal tract and cause nausea and vomiting. MATERIALS AND METHODS A rat model of simulated emesis was used to observe that cisplatin significantly increased kaolin consumption (or pica). Three GSEs from different sources were used in this study. RESULTS High-performance liquid chromatographic analysis of five major constituents (gallic acid, catechin, epicatechi, procyanidin B2, and epicatechin gallate) revealed that each constituent had different levels in the three GSEs. Extract #1, prepared in the laboratory of the investigators, had the lowest total polyphenol content (27.27 mg/g); Extract #2, obtained from a dietary supplement company in the United States, had a somewhat higher level (35.84 mg/g); and Extract #3, obtained from China, had the highest level (194.21 mg/g). Subsequently these GSEs were intraperitoneally administered in rats to evaluate their ability to decreasing cisplatin induced pica. At 10 mg/kg all three GSEs, with varying degrees of effect, decreased cisplatin-induced pica. The areas under the curves of kaolin intake from time 0 to 72 hours, compared to those in the cisplantin-only group, were reduced 45% for Extract #1 (p < 0.01), 54% for Extract #2 (p < 0.01), and 66% Extract #3 (p < 0.001). CONCLUSIONS The study data showed variable polyphenol contents and proportions in the three GSEs correlated to variable pharmacologic effects, indicating the importance of standardization of herbal product preparations. However further increasing of the GSE doses reversed the antipica effects of GSEs, probably because of their pro-oxidant effects. Results from this study suggest that an appropriate dose of GSE has therapeutic value in treating cisplatin-induced emesis.

Abstract
Several non-surgical tumor treatment modalities produce their cytotoxic activity by generating reactive oxygen species (ROS). Anti-oxidative enzymes such as superoxide dismutase (SOD) or exogenously supplied antioxidants may therefore reduce the efficacy of these treatments. The aim of the present study was to analyze the impact of (i) inhibiting SOD using 2-methoxyestradiol (2-ME), or (ii) application of alpha-tocopherol, on the cellular damage induced by hyperthermia (HT) in experimental tumors. DS-sarcoma cells grew either in culture or as solid tumors subcutaneously implanted in rats. In vitro, DS-cells were incubated with 2-ME, and cell proliferation, ROS formation, lipid peroxidation and apoptosis were measured. In vivo, DS-sarcomas were treated with a ROS-generating hyperthermia combined with 2-ME or alpha-tocopherol application. Inhibition of SOD by 2-ME in vitro induced pronounced oxidative injury resulting in reduced proliferation. In vivo, ROS-generating hyperthermia led to local tumor control in 23% of the animals. The additional inhibition of SOD by 2-ME increased the control rate by approximately 50%. Application of alpha-tocopherol was found to have no effect on local tumor control, either in combination with ROS-generating hyperthermia or when 2-ME was additionally applied. Inhibition of SOD during ROS-generating hyperthermia results in pronounced cell injury and an improved local tumor control whereas exogenously applied vitamin E seems not to have an impact on oxidative stress.

Abstract
BACKGROUND Inflammatory mechanisms may play an important role in the pathogenesis of cisplatin nephrotoxicity. Agonists of the peroxisome proliferator-activated receptor-gamma (PPARgamma), such as rosiglitazone, have been recently demonstrated to regulate inflammation by modulating the production of inflammatory mediators and adhesion molecules. The purpose of this study was to examine the protective effects of rosiglitazone on cisplatin nephrotoxicity and to explore the mechanism of its renoprotection. METHODS Mice were treated with cisplatin with or without pre-treatment with rosiglitazone. Renal functions, histological findings, aquaporin 2 (AQP2) and adhesion molecule expression, macrophage infiltration and tumour necrosis factor-alpha (TNF-alpha) levels were investigated. The effect of rosiglitazone on nuclear factor (NF)-kappaB activity and on viability was examined using cultured human kidney (HK-2) cells. RESULTS Rosiglitazone significantly decreased both the damage to renal function and histological pathology after cisplatin injection. Pre-treatment with rosiglitazone reduced the systemic levels of TNF-alpha and down-regulated adhesion molecule expression in addition to the infiltration of inflammatory cells after cisplatin administration. Rosiglitazone restored the decreased AQP2 expression after cisplatin treatment. Pre-treatment with rosiglitazone blocked the phosphorylation of the p65 subunit of NF-kappaB in cultured HK-2 cells. Rosiglitazone had a protective effect via a PPARgamma-dependent pathway in cisplatin-treated HK-2 cells. CONCLUSION These results showed that pre-treatment with rosiglitazone attenuates cisplatin-induced renal damage through the suppression of TNF-alpha overproduction and NF-kappaB activation.

Abstract
This study aims to elucidate the molecular mechanism(s) of cisplatin nephrotoxicity and the possible protective effects of antioxidant food supplementation on this toxicity. Twenty eight rats were used throughout the study. Cisplatin was administered intraperitoneally (i.p.) in a single dose (10 mg kg(-1)). Antioxidant food supplementation was started 3 days before cisplatin treatment. In each group (control, cisplatin, cisplatin plus dried black grape and cisplatin plus tomato juice), there were seven animals. Rats were killed 72 h after treatment. The kidneys were removed and prepared for biochemical and histopathological investigations. Oxidant (sensitivity to oxidation, xanthine oxidase enzyme and malondialdehyde level) and antioxidant (superoxide dismutase, glutathione peroxidase and catalase enzymes, and antioxidant potential value) parameters were measured in kidney tissues of the groups. Histopathological examination was also performed. Significant decreases were measured in the renal activities of catalase and glutathione peroxidase enzymes. There was, however, a significant increase in the activity of xanthine oxidase enzyme in the cisplatin-treated animals compared with the control group. The kidney tissue malondialdehyde levels were found to be increased, but sensitivity to oxidation and antioxidant potential values to be decreased in the cisplatin group. In the food supplemented groups, it has been observed that black grape eliminated oxidant stress by increasing antioxidant potential, but tomato did not. Histopathological examination results also revealed significant damage in the kidney tissues from the cisplatin-treated rats. In the black grape group, significant improvements were observed compared with the cisplatin group. In the tomato group, there were also some improvements but to a lesser degree compared with the black grape group. The results suggest that cisplatin treatment causes significant oxidant load to the kidneys through both xanthine oxidase activation and impaired antioxidant defense system, which resulted in accelerated oxidation reactions in the kidney tissue. It is proposed that supplementation of some foods such as black grape which has resveratrol as an antioxidant can provide significant protection against cisplatin nephrotoxicity.

Abstract
Changes in intracellular Ca2+ level are involved in a number of intracellular events, including triggering of apoptosis. The role of intracellular calcium mobilization in cisplatin-induced hair cell death, however, is still unknown. In this study, the effect of calcium channel blocker flunarizine (Sibelium), which is used to prescribe for vertigo and tinnitus, on cisplatin-induced hair cell death was investigated in a cochlear organ of Corti-derived cell line, HEI-OC1, and the neonatal (P2) rat organ of Corti explant. Cisplatin induced apoptotic cell death showing nuclear fragmentation, DNA ladder, and TUNEL positive in both HEI-OC1 and primary organ of Corti explant. Flunarizine significantly inhibited the cisplatin-induced apoptosis. Unexpectedly, flunarizine increased the intracellular calcium ([Ca2+]i) levels of HEI-OC1. However, the protective effect of flunarizine against cisplatin was not mediated by modulation of intracellular calcium level. Treatment of cisplatin resulted in ROS generation and lipid peroxidation in HEI-OC1. Flunarizine did not attenuate ROS production but inhibited lipid peroxidation and mitochondrial permeability transition in cisplatin-treated cells. This result suggests that the protective mechanism of flunarizine on cisplatin-induced cytotoxicity is associated with direct inhibition of lipid peroxidation and mitochondrial permeability transition.

Abstract
Zebrafish and other fish exhibit hair cells in the lateral-line neuromasts which are structurally and functionally similar to mammalian inner ear hair cells. To facilitate drug screening for ototoxic or otoprotective agents, we report a straightforward, quantitative in vivo assay to determine potential ototoxicity of drug candidates and to screen otoprotective agents in zebrafish larva. In this study, a fluorescent vital dye, DASPEI (2-(4-(dimethylamino)styryl)-N-ethylpyridinium iodide), was used to stain zebrafish hair cells in vivo and morphometric analysis was performed to quantify fluorescence intensity and convert images to numerical endpoints. Various therapeutics, including gentamicin, cisplatin, vinblastine sulfate, quinine, and neomycin, which cause ototoxicity in humans, also resulted in hair cell loss in zebrafish. In addition, protection against cisplatin-induced ototoxicity was observed in zebrafish larva co-treated with cisplatin and different antioxidants including, glutathione (GSH), allopurinol (ALO), N-acetyl l-cysteine (l-NAC), 2-oxothiazolidine-4-carboxylate (OTC) and d-methionine (d-MET). Our data indicate that results of ototoxicity and otoprotection in zebrafish correlated with results in humans, supporting use of zebrafish for preliminary drug screening.

Abstract
OBJECTIVE We investigated the effects of azuki bean (Vigna angularis) seed coats (ABSCs), which mainly contain proanthocyanidins and dietary fibers, on the infiltration of macrophages and the progression of renal interstitial fibrosis induced by cisplatin (CDDP). METHODS Male rats were divided into two groups: controls received intraperitoneal injections of saline and the other rats were injected intraperitoneally with 3 mg of CDDP per kilogram once a week for 5 wk. The CDDP-injected animals received one of four diets: 1) control diet (commercial diet only), 2) 0.5% red ABSC (RABSC) diet, 3) 2.0% RABSC diet, and 4) 2.0% white ABSC (WABSC) diet. The saline-injected animals were given the commercial diet. Five weeks after the final CDDP injection, macrophage kinetics and interstitial fibrotic areas were examined. RESULTS The content of polyphenols in the RABSC (76.3 g/kg of plant material) was higher than that in the WABSC (18.1 g/kg). Proanthocyanidins were detected in the RABSC (20.4 g/kg) but not in the WABSC. Histologically, the fibrotic areas consisting of fibroblastic cells and mononuclear cells developed around the dilated or atrophic tubules in the corticomedullary junction in CDDP-treated rat kidney, whereas the extent and magnitude of damage were less in the WABSC- and RABSC-treated rats. In immunohistochemical analysis, ED1-positive macrophages in CDDP-treated rats showed a significant increase in number compared with the control. The number of macrophages in CDDP plus WABSC or RABSC groups was significantly smaller than that in CDDP-treated rats. In addition, the number of macrophages in the RABSC group was significantly smaller than in the WABSC group, indicating that ABSC, especially RABSC, prevented macrophages from infiltrating into areas of interstitial fibrosis. CONCLUSIONS These results suggest that ABSC, especially RABSC, suppress the increase of infiltrating macrophages in the damaged kidney and may lead to amelioration of interstitial fibrosis. Based on the composition of ABSC, molecules such as proanthocyanidins and/or dietary fibers may be associated with the amelioration of renal damage.

Abstract
Recent studies have suggested that the induction of metallothionein synthesis in kidneys of mice by the acute administration of bismuth and other trace elements might protect against cis-diamminedichloroplatinum (II) nephrotoxicity. The present study was designed to determine the effects of dietary zinc and cis-diamminedichloroplatinum (II) on the induction of liver and kidney metallothionein and its subsequent effect on nephrotoxicity and trace element metabolism in rats. Male rats were fed diets containing 5, 20, 80, or 320 mg zinc/kg diet for 3 weeks. Each dietary group was subdivided into 3 groups. In one group, each rat received an i.p. injection of 7.5 mg cis-diamminedichloroplatinum (II)/kg b.w. All other rats received saline. During the next three days a second group of rats was pair-fed to the cis-diamminedichloroplatinum (II) injected group. A third group received no treatment and was allowed to eat ad libitum. Results showed that when dietary zinc was increased from 5 mg/kg diet to higher amounts, kidney metallothionein concentration increased twofold. cis-diamminedichloroplatinum (II) treatment increased kidney metallothionein even further, but elevated metallothionein gave no protection from the toxic effects of the drug. Serum copper concentration and ceruloplasmin activity were significantly lower with higher concentrations of dietary zinc, which indicated that these rats were mildly copper-deficient. There was a small but significant depression of superoxide dismutase activity and a highly significant increase in thiobarbituric acid reactive substances in kidneys of rats treated with cis-diamminedichloroplatinum (II) compared to either pair-fed or ad libitum controls. This supports the hypothesis that part of the mechanism for cis-diamminedichloroplatinum (II)-induced toxicity might be caused by free-radical generation. However, the data do not support the hypothesis that metallothionein induction protects the kidney from cis-diamminedichloroplatinum (II) toxicity.

Abstract
The effect of naringenin (NAR), a naturally occurring citrus flavanone, on the acute nephrotoxicity produced by cisplatin (7 mg/kg, i.v.) was investigated in the rat. Oral administration of NAR (20 mg/kg/day) for 10 days, starting 5 days before cisplatin single i.v. injection, produced significant protection of renal function. NAR reduced the extent of cisplatin-induced nephrotoxicity, as evidenced by significant reduction in serum urea and creatinine concentrations, decreased polyuria, reduction in body weight loss, marked reduction in urinary fractional sodium excretion and glutathione S-transferase (GST) activity, and increased creatinine clearance. Cisplatin-induced alterations in renal cortex lipid peroxides and GST activity were markedly improved by NAR. Cisplatin-induced alterations in renal cortex antioxidant defense system were greatly prevented by NAR. In cisplatin-NAR combined treatment group, antioxidant enzymes namely superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) were significantly increased to 54.5, 30.3 and 35.6%, respectively compared to cisplatin treated group. Platinum renal content was not affected by NAR treatment. The results provide further insight into the mechanisms of cisplatin-induced nephrotoxicity and confirm the antioxidant potential of NAR.
