Abstract
To evaluate the nephroprotective effect of edaravone on doxorubicin-induced nephrotoxicity. In this experimental study, twenty-eight Wistar male rats were used. The rats were separated into 4 groups (n = 7); group І (control), rats were treated with saline (4 ml/kg) and group ІІ (doxorubicin), nephrotoxicity was induced by three doses of 18 mg/kg/i.p. doxorubicin, at a 24-h interval on the 12th, 13th, and 14th days. Group ІІІ (edaravone), rats were treated with edaravone (30 mg/kg/for 14 days), and group ІV (edaravone + doxorubicin), rats were treated with edaravone (30 mg/kg/for 14 days) and doxorubicin were injected (18 mg/kg/for 3 days; at a 24-h interval on the 12th, 13th, and 14th days). On the 15th day of the experiment, technetium-99m-labeled dimercaptosuccinic acid ([99mTc]DMSA) uptake was obtained in both kidneys and biochemical parameters from serum and kidney tissue were measured. Doxorubicin led to nephrotoxicity through elevation of serum blood urea nitrogen (BUN), creatinine and tumor necrosis factor-α (TNF-α), nitric oxide (NO), and interleukin-6 (IL-6) in kidney tissue and decreased [99mTc]DMSA uptake level in the kidney when compared with control group (p < 0.01). Pretreatment edaravone significantly decreased BUN and creatinine, also kidney tissue TNF-α, IL-6, NO, and increased [99mTc]DMSA uptake level compared with the doxorubicin. Edaravone has a significant nephroprotective effect through the attenuation of oxidative stress and inflammatory markers during doxorubicin-induced nephrotoxicity in rats.

Abstract
BACKGROUND Nephrotoxicity is a prevalent consequence of cancer treatment using radiotherapy and chemotherapy or their combination. There are two methods; histological and biochemical, to assess the kidney damage caused by toxic agents in animal studies. Although these methods are used for the try-out of renoprotective factors, these methods are invasive and time-consuming, and also, lack the necessary sensitivity for primary diagnosis. Quantitative renal 99mTc-DMSA scintigraphy is a noninvasive, precise and sensitive radionuclide technique which is used to assess the extent of kidney damage, so that the extent of injury to the kidney will be indicated by the renal uptake rate of 99mTc-DMSA in the kidney. In addition, this scintigraphy evaluates the effect of the toxic agents by quantifying the alterations in the biodistribution of the radiopharmaceutical. CONCLUSION In this review, the recent findings about the renoprotective agents were evaluated and screened with respect to the use of 99mTc-DMSA , which is preclinically and clinically used for animal cases and cancer patients under the treatment by radiotherapy and chemotherapy.

Abstract
The clinical utility of aminoglycoside antibiotics is partly limited by their nephrotoxicity. Co-administration of a variety of candidate nephroprotectants has been tested at the preclinical level. According to a recent meta-analytic study, antioxidants are the only family of compounds with enough preclinical documentation to draw solid conclusions on their class nephroprotective capacity in animal models. In this study a systematic analysis of the relation between the level of antioxidation and the level of nephroprotection was performed. A regression model is presented which crosses the y-axis (i.e. the axis representing the level of nephroprotection) very nearly the zero value, meaning that maximal prevention of the oxidative stress induced by aminoglycosides results in almost maximal nephroprotection. This indicates that oxidative stress plays a central role in the hierarchy of pathophysiological mechanisms underlying aminoglycoside nephrotoxicity. In addition, this model may potentially serve: i) as a standard to evaluate the role of the antioxidant effect of candidate nephroprotectants; ii) to reveal additional, antioxidant-independent effects among those compounds providing more nephroprotection than that expected from its antioxidant activity; and thus iii) to discriminate and focus most effective nephroprotectants on clinical usage.

A systematic meta-analysis on the efficacy of pre-clinically tested nephroprotectants at preventing aminoglycoside nephrotoxicity. Toxicology 2016; 377:14-24. [PMID: 27940129 DOI: 10.1016/j.tox.2016.12.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Revised: 12/05/2016] [Accepted: 12/06/2016] [Indexed: 01/29/2023]
Abstract
Nephrotoxicity limits the use of aminoglycoside antibiotics. Kidney damage is produced mainly in the renal tubule due to an inflammatory and oxidative process. At preclinical level, many drugs and natural products have been tested as prospective protectors of aminoglycoside nephrotoxicity. The main objective of this work was to make a systematic literature review of preclinical studies about aminoglycoside nephrotoxicity protection and a statistical analysis based on the meta-analysis methodology. Studies published up to January 2016 were identified. After applying inclusion criteria, 54 studies were chosen. The size of the experimental groups, means and standard deviations of data on renal function (i.e. plasma creatinine and blood urea nitrogen [BUN] concentrations) were extracted and registered in a database. The studies were grouped according to the mechanism of nephroprotection and their route of administration. The Mean Difference (95% confidence interval) was calculated for each study and group. 40 of 54 products tested produced an amelioration of aminoglycoside nephrotoxicity based on creatinine results. Also a dose dependent protective effect was observed (both in creatinine and BUN). Products orally administered were more effective than via i.p. Products with attributed antioxidant activity were the most used and those which proved statistically significant nephroprotection as a class effect. Aminoglycoside tubular reuptake inhibitors, excretion inducers and calcium channel blockers also showed a promising and rather homogeneous class tendency towards nephroprotection, although more research is necessary to obtain solid and conclusive results, based on a larger number of studies.

Abstract
BACKGROUND In this study, we investigated the protective effect of thymol as a natural compound against cisplatin-induced nephrotoxicity by quantitative renal 99mTc-DMSA uptake and compared its effect with histopathology in mice. MATERIALS AND METHODS Mice were divided into six groups as control, cisplatin (7.5 mg/kg, intraperitoneally), thymol+cisplatin (thymol; 50 and 150 mg/kg+cisplatin; 7.5 mg/kg) and thymol (50 and 150 mg/kg). Thymol was orally administrated for two days before cisplatin injection and continued for 4 days. (99m)Tc-DMSA was injected through the tail of mice after the drug administration. The percentage of the injected dose per gram of kidney tissue (%ID/g) was calculated. In other experiment, kidneys of treated mice were assessed for histopathology. RESULTS 99mTc-DMSA uptake per gram tissue of the kidneys as %ID/g was 85.27±21.81, 45.55±5.50, 65.02±32.21 and 88.46±20.46 in the control, cisplatin, thymol (50 mg/kg)+cisplatin and thymol (150 mg/kg)+cisplatin. Thymol administration with cisplatin resulted in a significant increase in the level of %ID/g. Histopathological examinations showed a protective effect of thymol against cisplatin nephrotoxicity in mice. CONCLUSION The results showed that thymol significantly attenuates the cisplatin-induced nephrotoxicity in mice, and 99mTc-DMSA uptake in kidney is a suitable method for assessment of nephrotoxicity in mice.

Abstract
Background Sonchus asper possesses antioxidant capacity and is used in liver and kidney disorders. We have investigated the preventive effect of methanolic extract of Sonchus asper (SAME) on the gentamicin induced alterations in biochemical and morphological parameters in liver and kidneys of Sprague-Dawley male rat. Methods Acute oral toxicity studies were performed for selecting the therapeutic dose of SAME. 30 Sprague-Dawley male rats were equally divided into five groups with 06 animals in each. Group I received saline (0.5 ml/kg bw; 0.9% NaCl) while Group II administered with gentamicin 0.5 ml (100 mg/kg bw; i.p.) for ten days. Animals of Group III and Group IV received gentamicin and SAME 0.5 ml at a dose of 100 mg/kg bw and 200 mg/kg bw, respectively while Group V received only SAME at a dose of 200 mg/kg bw. Biochemical parameters including aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), γ-glutamyltransferase (γ-GT), total cholesterol, triglycerides, total protein, albumin, creatinine, blood urea nitrogen (BUN), total bilirubin and direct bilirubin were determined in serum collected from various groups. Urinary out puts were measured in each group and also assessed for the level of protein and glucose. Lipid peroxides (TBARS), glutathione (GSH), DNA injuries and activities of antioxidant enzymes; catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) were determined in liver and renal samples. Histopathological studies of liver and kidneys were also carried out. Results On the basis of acute oral toxicity studies, 2000 mg/kg bw did not induce any toxicity in rats, 1/10th of the dose was selected for preventive treatment. Gentamicin increased the level of serum biomarkers; AST, ALT, ALP, LDH, γ-GT, total cholesterol, triglycerides, total protein, albumin, creatinine, BUN, total and direct bilirubin; as were the urinary level of protein, glucose, and urinary output. Lipid peroxidation (TBARS) and DNA injuries increased while GSH contents and activities of antioxidant enzymes; CAT, POD, SOD decreased with gentamicin in liver and kidney samples. SAME administration, dose dependently, prevented the alteration in biochemical parameters and were supported by low level of tubular and glomerular injuries induced with gentamicin. Conclusion These results suggested the preventive role of SAME for gentamicin induced toxicity that could be attributed by phytochemicals having antioxidant and free radical scavenging properties.

Abstract
Objective. Cisplatin is a commonly used chemotherapeutic agent. One of its major dose-limiting side effects is ototoxicity. No treatment has yet been approved for this condition. The objective of this study was to determine the potential protective effect of a systemic administration of erdosteine against cisplatin-induced ototoxicity. Study Design. A prospective controlled trial conducted in an animal model. Setting. Animal care research facilities of The Montreal Children’s Hospital Research Institute. Subjects and Methods. A total of 27 guinea pigs were assigned to 4 groups, each receiving a different concentration of intraperitoneal erdosteine: group 1 (control group; n = 9) did not receive erdosteine, group 2 (n = 6) received 100 mg/kg/d, group 3 (n = 6) received 200 mg/kg/d, and group 4 (n = 6) received 500 mg/kg/d. The animals in the experimental groups received the erdosteine injection daily for 4 days. All of the animals received 12 mg/kg of intraperitoneal cisplatin. Auditory brainstem response threshold shifts were measured at 4 frequencies (8, 16, 20, and 25 kHz) for all groups. Scanning electron microscopy and outer hair cell counts were performed to assess the protective effect of erdosteine. Results. Significant protection was observed in groups 3 and 4 at 25 kHz. These findings are supported by outer hair cell counts by scanning electron microscopy. Conclusion. A systemic administration of erdosteine appears to provide an otoprotective effect at high frequencies for cisplatin-induced ototoxicity.

Abstract
Acute renal failure resulting from radiocontrast-induced nephrotoxicity (RIN) is suggested to occur via medullary ischemia coupled with the generation of free radicals and oxidative injury to tubular cells. The aim of the present study was to assess the effects of erdosteine on prevention of RIN. Thirty-three Wistar-albino rats were divided into five groups: control (group 1, n = 6), radiocontrast media (group 2, n = 6), erdosteine (group 3, n = 7), erdosteine four doses before radiocontrast application (group 4, n = 7) and erdosteine one dose at the same day with radiocontrast application (group 5, n = 7). RIN was induced by administration of intravenous high osmolar contrast media amidotrizoate (6 mL/kg). Total RNA was extracted from the kidney, and the expression levels of Lipocalin 2 (Lcn2) and secreted phosphoprotein 1 (Spp1) genes were evaluated by real time reverse transcription polymerase chain reaction (real-time RT-PCR). Total antioxidant status (TAS) and total oxidant status (TOS) were measured in kidney homogenates and serum samples. Serum creatinine, BUN (Blood Urea Nitrogen) and cystatin-C levels were measured from serum samples. The kidneys were evaluated histopathologically. The expression levels of Spp1 and Lcn2 genes in group 2 were significantly higher than groups 1, 3, 4, and 5. The expression levels of Spp1 and Lcn2 genes in group 4 were four and two times lower than group 5, respectively. Kidney TOS levels in group 2 were significantly higher than groups 1, 3, 4, and 5. Kidney TAS levels in group 3 were higher than group 2. Kidney oxidative stress index (OSI) levels in group 2 were significantly higher than groups 4 and 5. All rats in contrast media group developed tubular necrosis, proteinaceous casts, medullary congestion although these changes were significantly reduced in groups 4 and 5. This study demonstrated that multiple doses of erdosteine before application may have higher protective effects against RIN.

Abstract
Aim: The aim of the present study was to investigate the therapeutic and preventive effects of N-acetyl cysteine and erdosteine on renal injury associated with paracetamol (acetaminophen) intoxication. Materials and methods: Female albino Wistar rats were divided into six groups: control; paracetamol (1 g/kg, oral); paracetamol (1 g/kg, oral) + erdosteine (150 mg/kg/day, oral); paracetamol (1 g/kg, oral) + N-acetyl cysteine (140 mg/kg bolus, followed by 70 mg/kg, oral); N-acetyl cysteine control (140 mg/kg bolus, followed by 70 mg/kg, oral); and erdosteine control (150 mg/kg/day, oral). Potential renal injury was assessed using biochemical analyses, radionuclide imaging, and histopathological parameters. Results: In the paracetamol group, blood urea nitrogen and creatinine levels were significantly increased compared with controls. Histopathological examination showed tubular vacuolization, tubular necrosis, and remarkable interstitial inflammation. The excretion function was observed to be insufficient on radionuclide imaging. However, in the groups treated with erdosteine or N-acetyl cysteine after paracetamol, biochemical analyses, radionuclide imaging, and histopathological parameters showed significantly less evidence of renal toxicity than that observed in the group receiving paracetamol alone. Less renal toxicity was detected in rats receiving N-acetyl cysteine than in those receiving erdosteine. Conclusion: Renal injury may develop after paracetamol overdose. Erdosteine and N-acetyl cysteine are both effective in the prevention of renal injury when given in the early phase of paracetamol nephrotoxicity. N-acetyl cysteine is more protective than erdosteine.
