Purpose: Hyperhomocysteinemia in children can develop as a result of genetic defects, endocrine abnormalities or under the influence dietary factors. An elevated level homocysteine is considered risk factor for progression chronic kidney disease. The aim work was to investigate indicators oxidative stress homogenate kidneys immature rats control and with hyperhomocysteinemia. Methods: concentra...

Curcumin, a safe nutritional component and a highly promising natural antioxidant with a wide spectrum of biological functions, has been examined in several metal toxicity studies, but its role in protection against mercury toxicity has not been investigated. Therefore, the detoxification and antioxidant effects of curcumin were examined to determine its prophylactic/therapeutic role in rats ex...

Introduction: This study evaluated the effects of pretreatments with melatonin (MT), and Alpha Lipoic acid (ALA) on lopinavir/ritonavir (LPV/r) -induced serum levels of creatinine (Cr), urea (U), uric acid (Ua) and kidney levels of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH) and catalase (CAT) in male albino rats. Effects of treatments with MT and ALA were also evaluate...

Cisplatin (CP) is an anticancer drug that enhances renal generation of reactive oxygen metabolites, lipid peroxidation and inflammation. This study examined the effect of hydrogen sulfide on lipid peroxidation content, tissue antioxidant enzyme activities and tumor necrosis factor (TNF-α) in cisplatin nephrotoxic rats. Thirty male Sprague-Dawley rats were divided into three groups of 10 rats in...

Metal toxicity is a threat mainly in the industrialised world where industry discharges many toxic metals into the environment. We investigated the effects of two metals – cadmium and selenium – on the cytosolic antioxidant enzymes and esterases in the liver, kidneys and testes of rats. Male Sprague-Dawley rats (n=28) were divided equally into four groups: control, cadmium, selenium and cadmium...

PURPOSE The purpose of this study was to investigate the therapeutic and protective effects of molsidomine (MLS) against doxorubicin (DOX)-induced renal damage in rats. METHODS Forty rats were randomly divided into five groups (control, MLS, DOX, DOX+MLS and MLS+DOX groups). Thiobarbituric acid reactive substance (TBARS), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), ...

Glutathione peroxidase-3 (Gpx3), the extracellular glutathione peroxidase synthesized largely in the kidney, binds to basement membranes of renal cortical epithelial cells. The present study assessed extrarenal expression of Gpx3 using RT-PCR and presence of Gpx3 protein using immunocytochemistry. Gpx3 expression was higher in kidney and epididymis than in other tissues. Gpx3 bound to basement ...

Several halogenated alkenes are nephrotoxic; some others induce renal tubular adenocarcinomas in rodents after lifelong administration. A bioactivation mechanism accounting for the organ-selective tumor induction has been elucidated: conjugation of the parent compounds with glutathione (GSH), catalyzed by hepatic GSH S-transferases, results in the formation of haloalkyl and halovinyl glutathion...

background: vanadium is an important environmental and industrial pollutant. it has a status of reproductive toxicant and is reported to cross placental barrier. objective: the current study was performed to assess the therapeutic efficacy of tiron and its combination with selenium against vanadium induced toxicity in lactating and suckling rats. materials and methods: rats were exposed to vana...

The effects of dietary clofibrate on the epoxide-metabolizing enzymes of mouse liver, kidney, lung and testis were evaluated using trans-stilbene oxide as a selective substrate for the cytosolic epoxide hydrolase, cis-stilbene oxide and benzo[a]pyrene 4,5-oxide as substrates for the microsomal form, and cis-stilbene oxide as a substrate for glutathione S-transferase activity. The hydration of t...
