Abstract
Investigation the protective effect of transient receptor potential channel modulator 2-Aminoethoxydiphenyl Borate (2-APB) on aminoglycoside nephrotoxicity caused by reactive oxygen species, calcium-induced apoptosis and inflammation was aimed. Forty Wistar rats were divided (n=8) as follows: Control group; DMSO group; 2-APB group; Gentamicin group (injected 100 mg/kg gentamicin intramuscularly for 10 days); Gentamicin+ 2-APB group (injected 2 mg/kg 2-APB intraperitoneally, then after 30 minutes 100 mg/kg gentamicin was injected intramuscularly for 10 days). Blood samples were collected for biochemical analyses, kidney tissue samples were collected for light, electron microscopic and immunohistochemical investigations. In gentamicin group glomerular degeneration, tubular dilatation, vacuolization, desquamation of tubular cells and hyaline cast formation in luminal space and leukocyte infiltration were seen. Disorganization of microvilli of tubular cells, apical cytoplasmic blebbing, lipid accumulation, myelin figure like structure formation, increased lysosomes, mitochondrial swelling and disorganization of cristae structures, apoptotic changes and widening of intercellular space were found. TNF-α, IL-6 and caspase 3 expressions were increased. BUN and creatinine concentrations were increased. Increase in MDA levels and decrease in SOD activities were determined. Even though degeneration still continues in gentamicin+2-APB treatment group, severity and the area it occupied were decreased and the glomerular and tubule structures were generally preserved. TNF-α, IL-6, caspase 3 immunoreactivities and BUN, creatinine, MDA concentrations were reduced and SOD activities were increased markedly compared to gentamicin group. In conclusion, it has been considered that 2-APB can prevent gentamicin mediated nephrotoxicity with its anti-oxidant, anti-apoptotic and anti-inflammatory effects.

Abstract
Gentamicin (GM) is an aminoglycoside antibiotic that induces nephrotoxicity. GM also causes necrosis of cells in the renal proximal tubules, resulting in acute tubular necrosis, followed by acute renal failure. Morphological alteration of blood cells, leukocytes and platelets count, as well as biochemical effects of L-cysteine (Cys) and antibiotic gentamicin, in clinically healthy male Wistar rats, were studied. Rats were divided into four groups: control (injected with 0.9% saline i.p.), GM (80 mg/kg b.w.; gentamicin injected i.p.), Cys-GM (100 mg/kg b.w.; L-cysteine and 80 mg/kg b.w. gentamicin injected i.p.), and Cys-GM-Cys (administered double dosage of 100 mg/kg b.w. L-cysteine and 80 mg/kg b.w. gentamicin i.p.). Biochemical and hematological analyses were performed on blood samples taken six days after treatments. Total proteins, albumin concentration and A/G ratio were significantly lower in experimental groups. Cholesterol, triglycerides, urea, and creatinine concentrations were significantly higher in relation to control. GM-induced lymphocytopenia, thrombocytopenia and neutrophilia. Echinocytosis and platelet disaggregation were found in all GM-treated animals. GM caused renal injury which indirectly led to erythrocyte abnormalities, changes in platelet aggregation, decreased protein fractions, and increased lipid and nitrogen components. The results suggest that GM-induced renal injury leads to significant biochemical changes in blood plasma, erythrocyte membrane impairment which can consequently cause anemia. Therefore, Cys might represent a novel therapeutic tool in the prevention and treatment of gentamicin-induced renal injury and blood cell disorders.

Abstract
Ethephon is an organophosphorus plant growth regulator used to accelerate the ripening process and decrease the duration of cultivation. Here, the potential protective role of aged garlic extract (AGE) was investigated against ethephon-mediated nephrotoxicity. Four experimental groups were established (n = 15), including control, AGE (250 mg/kg), ethephon (200 mg/kg), and AGE + ethephon. In the current work, kidney function parameters (urea, creatinine, and KIM-1) along with oxidative stress biomarkers, nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1, glutathione, and its related enzymes, superoxide dismutase, catalase, malondialdehyde, and nitric oxide, were determined. The expression of inflammatory mediators namely tumor necrosis factor alpha, interleukin 1 beta, nuclear factor kappa B, and apoptotic markers (caspase 3, Bax, and Bcl2) were determined in the renal tissue. Additionally, the histopathological alterations in response to treatments were examined. Ethephon exposure increased the levels of kidney function markers along with relative kidney weight coupled with histological changes in the kidney tissue. Additionally, ethephon increased the levels of the tested pro-oxidant markers and decreased the antioxidant indices, resulting in oxidative damage to renal tissues. An elevation in the pro-inflammatory mediators was also recorded following ethephon intoxication. Furthermore, renal cell loss was observed through histological examinations and biochemical measurements upon ethephon administration. On the other hand, AGE significantly ameliorated the molecular, biochemical, and structural changes elicited by ethephon. These findings suggest that AGE may be used to decrease or prevent the side effects of ethephon exposure in kidneys, through the activation of Nrf2 and inhibition of inflammation and apoptotic response.

Abstract
We studied the hepatic and renal impact of sodium metavanadate (SMV) exposure in African giant rats (AGR). Twelve male AGR were used and divided into two groups. The control group received sterile water while the SMV-exposed group received 3 mg/kg SMV intraperitoneally for 14 days. SMV exposed AGR groups showed significantly decreased activities of serum AST, ALT, ALP and creatinine concentration but increased blood urea nitrogen (BUN), albumin and globulin concentrations. Kidney ultrastructure examination revealed atrophy of the glomerular tuft, loss of podocytes, distortions of the endothelium and glomerular basement membrane. The liver sinusoids fenestration phenotypes were abnormal. Hepatocytes exhibited hypertrophy with uneven, crenated and dentate nuclei. SMV exposure induced activation of monocytes, as well as Kupffer and fibrous cells. Alterations in glomerular podocytes and cell-cell and cell matrix contact and inflammatory liver fibrosis are key events in progressive glomerular failure and hepatic damage due to SMV intoxication.

Abstract
Context: The kidney plays a central role in detoxification and excretion of toxic metabolites, and therefore, is susceptible to toxicity by xenobiotics.Objective: To investigate the protective effect of Rosmarinus officinalis (rosemary) powder and its essential (volatile) oil against diethylnitrosamine (DEN)-induced renal injury in rats.Materials and methods: Phenolic and flavonoid components were characterised in rosemary powder using HPLC-UV instrument while rosemary essential oil (E.O) was investigated via GC-MS technique. In rat model, rosemary was administrated orally (in diet) for two months. Lipid profile, antioxidant biomarkers, kidney functions and histopathological examinations were assessed.Results: Hesperidin (4878.88 ppm) and ellagic acid (403.57 ppm) are among the major phenolic and flavonoid constituents in rosemary powder. Camphor (18.36%) and α-pinene (12.74%) represent the main E.O active ingredients. Rats treated with rosemary E.O showed a significant elevation in serum HDL (28.28%) accompanied by a decrease in LDL (115.47%). A significant decrease in serum creatinine and urea was also reported (69.72 and 109.89%, respectively). Moreover, serum glutathione peroxidise (GSH-Px) activity has been significantly increased. Kidney histopathological examinations confirmed the protective effect against DEN-induced abnormalities.Conclusion: Rosemary (powder/E.O) was able to reduce or even prevent the severity of diethylnitrosamine-induced renal dysfunction.

Abstract
Acute kidney injury (AKI) and chronic kidney disease (CKD) are worldwide public health problems affecting millions of people and have rapidly increased in prevalence in recent years. Due to the multiple causes of renal failure, many animal models have been developed to advance our understanding of human nephropathy. Among these experimental models, rodents have been extensively used to enable mechanistic understanding of kidney disease induction and progression, as well as to identify potential targets for therapy. In this review, we discuss AKI models induced by surgical operation and drugs or toxins, as well as a variety of CKD models (mainly genetically modified mouse models). Results from recent and ongoing clinical trials and conceptual advances derived from animal models are also explored.

Abstract
We studied the effect of α-tocopherol on gentamicin-induced morphological and functional changes in the kidneys of Wistar rats. Special attention was paid to the ability of α-tocopherol administered in combination with gentamicin to correct ultrastructural changes in the glomerular basal membrane and tubules. Combined treatment with α-tocopherol (100 mg/kg) and gentamicin (100 mg/kg) led to correction of histopathological and biochemical changes and oxidative injury to the kidneys induced by this antibiotic.

Abstract
Bile salts containing vesicles (bilosomes) represent a portentous vesicular carrier that showed prosperous results in delivering active moieties in the gastrointestinal tract (GIT). In this study, bilosomes were exploited to deliver sulfated polysaccharide-protein complexes of Enteromorpha intestinalis (EHEM) and enhance its activity against hepatocellular carcinoma as well as resist harsh GIT conditions. Bilosomes were prepared using the sodium salt of three different bile acids (cholic, deoxycholic, taurodeoxycholic) and two different nonionic surfactants (Span 40 and 65). The effects of experimental variables were thoroughly studied to obtain an optimum formulation loading EHEM. The selected formulation (EH-Bilo-2) prepared with sodium cholate and Span 65 displayed nano-sized (181.1 ± 16.80 nm) spherical vesicles with reasonable entrapment efficiency (71.60 ± 0.25%) and controlled release properties; and thus was investigated as anti-hepatocarcinogenic candidate for in vivo studies. Treatment of hepatocellular carcinoma (HCC) bearing rats with EH-Bilo-2 experienced significant decrease in serum α-fetoprotein, endoglin, lipocalin-2, and heat shock protein 70 levels vs. the untreated counterparts. Furthermore, the photomicrographs of their liver tissue sections showed focal area of degenerated pleomorphic hepatocytes with fine fibrosis originating from the portal area. Thus, the optimized bilosomal formulation is a promising delegate for tackling hepatocellular carcinoma owing to its powerful anti-cancer and anti-angiogenic activity.

Abstract
Due to high relative blood flow the kidney is prone to drug-induced damage. Aminoglycoside type antibiotic gentamicin is one of the leading cause of drug-induced nephrotoxicity. In recent years gentamicin nephrotoxicity is significantly reduced by shifting to once daily dosage as well as by eliminating known risk factors. Application of gentamicin is still related to serious side effects which are reported more often compared to other antibiotics. Because gentamicin is still heavily used and is highly efficient in treating infections, it is important to find mechanisms to reduce its nephrotoxicity. This aim can only be achieved through better understanding of kidney metabolism of gentamicin. This problem has been extensively researched in the last 20 years. The experimental results have provided evidence for almost complete understanding of mechanisms responsible for gentamicin nephrotoxicity. We now have well described morphological, biochemical and functional changes in kidney due to gentamicin application. During the years, this model has become so popular that now it is used as an experimental model for nephrotoxicity per se. This situation can mislead an ordinary reader of scientific literature that we know everything about it and there is nothing new to discover here. But quite opposite is true. The precise and complete mechanism of gentamicin nephrotoxicity is still point of speculation and an unfinished story. With emerge of new and versatile technics in biomedicine we have an opportunity to reexamine old beliefs and discover new facts. This review focuses on current knowledge in this area and gives some future perspectives.

Abstract
Background Morinda pubescens J.E.Sm. (Rubiaceae) is an important medicinal plant used in indigenous system of medicine i.e., Ayurveda, Siddha and Unani. Objective The aim of this study is to evaluate the nephroprotective effect of M. pubescens in gentamicin induced acute renal failure in rats. Methods Nephrotoxicity was induced in male Wistar rats by administration of gentamicin (100 mg/kg, i.p.) once daily for 10 days. Simultaneously, the treatment was conducted with water extract bark of M. pubescens (200 mg/kg, p.o.) and its ethyl acetate fractions (100 mg/kg, p.o.) once daily for ten days. Silymarin (50 mg/kg, p.o.) is used as standard drug. Using renal biochemical markers creatinine, urea, uric acid, BUN, albumin, protein, and other parameters are kidney weight, body weight, urine volume and histopathology of the kidney. Statistical analysis was performed by using one - way ANOVA followed by Dunnett's test. Results It was observed that the water extract and its ethyl acetate fractions bark of M. pubescens has brought back the altered levels of biochemical markers and other parameters to the near normal levels. Histopathological study revealed treatment groups also shows the normal texture of kidney. Conclusions The present study possessed nephroprotective activity but ethyl acetate fraction was found to exhibit greater nephroprotective activity than the water extract.

Abstract
Introduction: L-arginine has a protective effect on gentamicin-induced renal failure and it may decrease the tubular reabsorption of another cationic substance, gentamicin due to its cationic structure. The aim of this study is to compare the possible protective effects of L-arginine and its inactive isomer D-arginine on gentamicin-induced nephrotoxicity in rats. Materials and Methods: Wistar albino rats were housed in metabolic cages and assigned to six groups as: control group, gentamicin (100 mg/kg), gentamicin + L-arginine (2 g/l), gentamicin + D-arginine (2 g/l), gentamicin + L-arginine + Nv-nitro-L-arginine methyl ester (L-NAME) (100 mg/l) and gentamicin + D-arginine + L-NAME. Gentamicin was administered by subcutaneous injections and the other drugs were added in drinking water for seven consecutive days. The animals were killed by decapitation and intracardiac blood and urine samples were obtained on the seventh day. Blood urea nitrogen, serum creatinine, sodium, potassium, urine gamma glutamyl transferase, creatinine, sodium, potassium and gentamicin levels were measured using High Performance Liquid Chromatography (HPLC) technique. Results: Gentamicin treated group had significant increase in blood urea nitrogen, serum creatinine, fractional Na excretion and urine gamma glutamyl transferase levels, and significant decrease in creatinine clearance compared to the control group. L-arginine and D-arginine reversed these findings. L-NAME abolished the nephroprotective effect of L-arginine. The urinary levels of gentamicin were significantly increased in rats treated with L-arginine or D-arginine compared to those treated with gentamicin. L-arginine and D-arginine reversed the advanced degenerative changes due to gentamicin administration in histopathological examination. Conclusion: Our study revealed the protective effect of L-arginine on gentamicin-induced nephrotoxicity, the contribution of the cationic feature of L-arginine, and the major role of NO in this protective effect.

Abstract
Gentamicin (GM) is a widely used antibiotic against serious and life-threatening infections, but its usefulness is limited by the development of nephrotoxicity. The present study was designed to determine the protective effect of salicylic acid (SA) in gentamicin-induced nephrotoxicity in rats. Quantitative evaluation of gentamicin-induced structural alterations and degree of functional alterations in the kidneys were performed by histopathological and biochemical analyses in order to determine potential beneficial effects of SA coadministration with gentamicin. Gentamicin was observed to cause a severe nephrotoxicity which was evidenced by an elevation of serum urea and creatinine levels. The significant increases in malondialdehyde (MDA) levels and protein carbonyl groups indicated that GM-induced tissue injury was mediated through oxidative reactions. On the other hand, simultaneous SA administration protected kidney tissue against the oxidative damage and the nephrotoxic effect caused by GM treatment. Exposure to GM caused necrosis of tubular epithelial cells. Necrosis of tubules was found to be prevented by SA pretreatment. The results from our study indicate that SA supplement attenuates oxidative-stress associated renal injury by reducing oxygen free radicals and lipid peroxidation in gentamicin-treated rats.

Abstract
The present investigation reports the effect of rosmarinic acid (RA), an antioxidant on gentamicin sulphate (GS)-induced renal oxidative damage in rats. Rosmarinic acid (RA) has been demonstrated to have antioxidant, free radical scavenger and anti-inflammatory effects. Twenty-eight Sprague-Dawley rats were divided in to four equal groups as follows: group 1 (control), group 2 (GS 100 mg/kg/d ip), group 3 (GS 100 mg/kg/d ip+RA 50 mg/kg/d) and group 4 (GS 100 mg/kg/d ip+RA 100 mg/kg/d). Treatments were administrated once daily for 12 days. After 12 days 24h urine was collected, blood was sampled and kidneys were removed. Serum and kidney tissue MDA assessed by thiobarbituric acid. Kidney paraffin sections (5 μm thickness) from the left kidney stained with periodic acid Schiff. Tubular necrosis was studied semiquantitatively and glomerular volume and volume density of proximal convoluted tubule (PCT) estimated stereologically. Kidney homogenize were prepared from right kidney. Serum creatinine, urea and kidney antioxidant enzymes activity were assessed by special kits. Data were compared by SPSS 13 software and Mann-Whitney test at p < 0.05. Co treatment of GS and RA (High dose) significantly decreased serum creatinine, MDA, urea, tubular necrosis (p < 0.05) and increase renal GSH, GPX, CAT, SOD, volume density of PCT and creatinine clearance significantly in comparison with GS group (p < 0.05). Treatment with RA (high dose) maintained serum creatinine, volume density of PCT, renal GSH, GPX, SOD and MDA as the same level as control group significantly (p < 0.05). In conclusion, RA alleviates GS nephrotoxicity via antioxidant activity, increase of renal GSH content and increase of renal antioxidant enzymes activity.

Abstract
Nephrotoxicity is one of the most important side effects and therapeutical limitations of aminoglycoside antibiotics, especially gentamicin. Despite rigorous patient monitoring, nephrotoxicity appears in 10-25% of therapeutic courses. Traditionally, aminoglycoside nephrotoxicity has been considered to result mainly from tubular damage. Both lethal and sub-lethal alterations in tubular cells handicap reabsorption and, in severe cases, may lead to a significant tubular obstruction. However, a reduced glomerular filtration is necessary to explain the symptoms of the disease. Reduced filtration is not solely the result of tubular obstruction and tubular malfunction, resulting in tubuloglomerular feedback activation; renal vasoconstriction and mesangial contraction are also crucial to fully explain aminoglycoside nephrotoxicity. This review critically presents an integrative view on the interactions of tubular, glomerular, and vascular effects of gentamicin, in the context of the most recent information available. Moreover, it discusses therapeutic perspectives for prevention of aminoglycoside nephrotoxicity derived from the pathophysiological knowledge.

Abstract
Gentamicin is commonly used for the treatment of severe gram negative bacterial infections but inevitably cause renal failure during prolonged use. The aim of our study was to emphasize protective effects of pentoxifylline on glomerular basement membrane (GBM) alterations induced by gentamicin in rats. Experiments were done on 40 male Wistar rats divided in three experimental groups. GM-group was treated daily with gentamicin in dose of 100 mg/kg during 8 days. PTX-group was treated daily with pentoxifylline in dose of 45 mg/kg and the same dose of gentamicin as in GM-group during 8 days. The control group received 1 ml/day saline intraperitoneally. Morphometric parameter measured during the analysis was glomerular basement membrane thickness. In GM-group of animals glomeruli were enlarged and GMB was diffusely and unequally thickened with neutrophil cells infiltration. In proximal tubules epithelial cells, vacuolization of cytoplasm with coagulation-type necrosis were observed. In PTX-group of animals glomeruli were somewhat enlarged and GBM was thickened only in some segments. Coagulation-type necrosis was not found. Blood urea and serum creatinine concentration in GM-group were significantly elevated in comparison with PTX-group while potassium level was decreased. Our results suggest that PTX has protective effects on GBM and proximal tubules in GM-treated rats.
