Depth Analysis

Background: Despite being one of the most nephrotoxic drugs, gentamicin (GM) remains a mainstay as a first-choice agent in a vast variety of clinical situations owing to its superlative efficiency as a broad-spectrum antibiotic in treating several life-threatening bacterial infections. This urgently calls for the need for in-depth analysis of the mechanisms governing GM-induced nephrotoxicity and entails the necessity of presenting novel protective agents capable of ameliorating those renal deleterious effects. The reactive oxygen species and redox-sensitive transcription factors in GM-induced nephrotoxicity have recently called attention. Purpose: This study has been designed to shed light on the possible mechanisms of GM-induced nephrotoxicity and to provide a consensus set of histopathological, immunohistochemical, genetic and biochemical parameters elucidating the protective role of vitamin D against this nephrotoxicity. Methods: Twenty-four adult male albino rats were equally divided into four groups: group I (control group), group II (GM), group III (GM + vitamin D) and group IV (vitamin D only). Kidney function tests, histopathological examination, gene expression of nuclear factor 2, nuclear factor kappa beta (NF-κB) and western blot of NF-κB p65, assessment of glutathione peroxidase and nicotinamide adenine dinucleotide phosphate oxidase (NADPH) oxidase by ELISA, as well as immunohistochemical evaluation of inducible nitric oxide, malondialdehyde, 8-hydroxy 2 deoxyguanine and vitamin D receptor, have been carried out. Results: The kidney function deterioration, tissue oxidative stress development and the histopathological changes induced by GM were significantly attenuated by vitamin D administration. Conclusion: Vitamin D attenuates GM nephrotoxicity through its antioxidant properties and prevention of DNA damage.

Mercury is a harmful toxic pollutant, which has hepato-nephrotoxic, hematotoxic, genotoxic and neurotoxic, effects. The aim of the study was to evaluate the protective efficacy of wheatgrass on mercuric chloride (HgCl2) induced oxidative stress and associated complications in rat model. Albino rats were divided into four groups (three rats per group). Group I normal control group. Group II oxidative stressed group received mercuric chloride (0.5 mg/kg/day). Group III only received wheatgrass extract (100 mg/kg/day), whereas Group IV received wheatgrass (100 mg/kg/day) after one hour, followed by mercuric chloride (0.5 mg/kg/day) for 30 days. The results of the study showed that wheatgrass supplementation significantly decreased the HgCl2 induced elevated oxidative stress parameters Plasma Malondialdehyde (MDA) content, Plasma membrane redox system (PMRS), Advanced oxidation protein products (AOPP), simultaneously elevated lipid profile (Total Cholesterol, Triglycerides, Low-density lipoprotein (LDL), liver enzymes as, Plasma Alkaline phosphatase (ALP), Aspartate aminotransferase (AST), and Alanine aminotransferase (ALT), Serum Urea, and Creatinine levels in rats. In addition, wheatgrass treatment improved the antioxidant status in terms of intracellular Reduced Glutathione (GSH), Ferric reducing antioxidant power (FRAP) and 2, 2- diphenyl -1- picrylhydrazyl (DPPH). Therefore it can be concluded that wheatgrass has great potential to diminish the stress-mediated complications and improve the antioxidant status.

Background: The optimal use of oxygen at greater than atmospheric pressures in any operational or therapeutic application (hyperbaric oxygen, HBO2) requires awareness of the fact that the beneficial effects of oxygen coexist with toxic effects depending on the pressure and duration of exposure. In this study, we aimed to investigate the effect of HBO2 therapy on oxidative stress and antioxidant status in commonly used protocol for acute HBO2 indications, such as carbon monoxide intoxication, central retinal artery occlusion, crush injury, gas gangrene, and to compare it with normobaric oxygen (NBO2) in healthy rats. Materials and Methods: Fifty-six male, young adult Wistar albino rats were randomly divided into seven groups and named as Group I through Group VII. Plasma malondialdehyde (MDA), superoxide dismutase (SOD), and erythrocyte glutathione (GSH) levels in control group were compared to the levels in other groups. Results: The increases in MDA levels and the decrease in SOD activities were statistically significant in HBO2 groups at the end of the first 24 h when compared to the control group, and the significant decrease in erythrocyte GSH level was only at 2.4 atmospheres absolute. Conclusions: The present study showed that pressure and frequency of exposure are important factors to consider when investigating HBO2-induced oxidative stress and antioxidant response.

Silver nanoparticles (AgNPs) are gaining interest in medical applications for their prominent antibacterial and antimicrobial potentials. AgNPs possess remarkable anti-inflammatory and antioxidant activities and enhances wound healing. The main objective of the current study was to investigate the therapeutic effect of administration of AgNPs on cisplatin (CP) induced pulmonary inflammation in rats. Sixty male albino rats were used in this study. Rats were divided into 6 groups (n=10). Group I control group. Group II and III control groups received AgNPs at doses (5 and 10 ppm). Group IV CP group received CP (2.5 mg/kg). Group V and VI CP group received AgNPs (5, and 10 ppm). All doses were administered intraperitoneally once a day for 4 weeks. Oxidative stress and antioxidant status, inflammatory mediators, fibrogenic as well as apoptotic markers were determined in lung tissues. The results revealed that rats treated with CP showed remarkable elevation in lung tissues MDA, TNF-α, IFN-γ, IL-6, CRP, Fibrinogen and P53 levels associated with depression in SOD, GSH and CAT activities. However, administration of AgNPs (5 or 10 ppm) to CP group resulted in significant amelioration of the aforementioned parameters in a dose dependent manner. Histopathological investigation of lung tissues of CP group demonstrated disruption of normal lung architecture and lung injury. However, treatment with AgNPs revealed significant improvement in lung tissue against CP- induced inflammatory changes and lung tissue damage. It could be concluded that AgNPs exert potent cytoprotective effects via combating oxidative stress, inflammation, fibrogenic and apoptotic markers and repairing histopathological changes in lung tissues.

Malathion can be ingested, inhaled, or absorbed through the skin, but acute toxicity is maximized when administered orally. Intravenous lipid emulsion (ILE) treatment is used as a new therapeutic method in cases of systemic toxicity caused by some lipid soluble agents. This study aimed to examine the potential treatment effect of ILE on rat lung tissue in a toxicokinetic model of malathion exposure. Twenty-one adult Wistar albino rats were randomly divided into three equal groups. The groups were organized as group I (control), group II (malathion), and group III (malathion + ILE treatment). Malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) were evaluated in lung tissues. Immunohistochemical and Western blot analyses were performed to determine the bax, bcl-2, and caspase-3 expression levels. Tissue GSH-Px and SOD activities were decreased and MDA levels were increased in the malathion group. ILE administration increased GSH-Px and SOD activity and decreased MDA levels compared to the malathion group. Furthermore, expression of bax, bcl-2, and caspase-3 significantly increased in the malathion group, and ILE infusion reduced these expression levels. The present study revealed that acute oral malathion administration increased oxidative stress and apoptosis in the lung tissue of rats. ILE infusion prevented oxidative stress and decreased the deleterious effects of malathion. Taken together, the findings of our study suggest that lipid emulsion infusion has treatment efficacy on malathion-induced lung toxicity.

Introduction: Monosodium L-glutamate (MSG) monohydrate is a widespread nutritional additive and flavoring agent frequently consumed all over the world. In this study, we investigate the action of daily oral intake of MSG monohydrate in vivo using mammalian systems. Methods: Mice divided as follows: Group I (normal control), Group II, and Group III treated with MSG for 2 and 4 weeks, respectively. Brain and liver dissected out for the detection of fragmented DNA, DNA damage, and assay of oxidative stress markers. Moreover, expression levels of ß-Cat and p53 genes were measured by a real-time quantitative polymerase chain reaction. Results: The results showed a significant difference in MSG-treated group at the 2-time intervals than the control one regarding parameters of oxidative stress, and these were accompanied by a significant decline in glutathione (GSH) and a ratio of oxidized and reduced GSH in both tissues. Significant elevation of laddered DNA and oxidative DNA damage was observed in groups treated with MSG. In addition, a significant decline in gene expression of ß-Catenin in liver and brain tissues with elevations in the gene expression of p53 in the brain. Furthermore, the p53 gene in liver tissue was significantly upregulated in mice administered MSG for 15 days and was downregulated after 30 days of MSG intake compared with the control. Conclusion: According to our results, oral consumption of MSG leads to oxidative stress-mediated DNA damage and apoptosis.

Abstract Background Eugenol is the foremost constituent of clove oil and widely distributed in many plants. It possesses many pharmaceutical applications, including antioxidant, anti-inflammatory, and anti-tumorigenic properties, among others. This study evaluates the influence of eugenol on oxidative stress biomarkers in the liver of carrageenan-induced arthritis (CIA) rats. Methods Sixty albino rats were randomly divided into 10 (n=6) groups. Group I is the control group that received saline solution orally. Groups II and VII rats received 2.5 mg/kg of eugenol orally (EUG-2.5). Rats in groups III/VIII and IV/IX received 5 and 10 mg/kg of eugenol orally (EUG-5 and EUG-10), respectively. Groups V and X received 0.2 mg/kg of dexamethasone (DEX-0.2) orally. Groups VI to X were injected with 1% carrageenan intra-articularly. Behavioral studies were conducted after 21 days of treatment. Thereafter, the animals were sacrificed, and the livers were isolated and used for biochemical analysis. Results Reduced body weight in arthritic rats was recorded compared to normal controls. Reduced tibiofemoral joint edema and increased spontaneous movement were observed in CIA rats with decreased superoxide dismutase, catalase, reduced glutathione (GSH), glutathione peroxidase, and GSH S-transferase activities compared with the normal control group. Increased endogenous enzyme activities and decreased elevated lipid peroxidation were also observed after eugenol treatment. Conclusion Eugenol ameliorates carrageenan-induced oxidative stress in the liver of arthritic rats.

Objective: κ-carrageenan is a food stabilizer agent which has an antiproliferative effect, while vitamin D is a prohormone acts on the nuclear receptor and has a cytotoxic against cancer. This study aimed to show the synergistic effect of using topical κ-carrageenan and oral administration of the vitamin D on the 7, 12-dimethylbenz[a] anthracene (DMBA)-induced oral cancer. Material and Methods: fifty four male albino rats were randomly divided into seven groups: Acetone-treated served as control (Group I), vitamin D (5000UI)-treated (Group II), κ-carrageenan (1%)- treated (Group III), DMBA (0.5%)-treated (Group IV), Acetone, κ-carrageenan and DMBA were administered topically on both cheeks and palate, five times weekly for 12 weeks, while the vitamin D was  administered orally twice weekly for 12 weeks. Groups V, VI, and VII were animals treated with vitamin D, κ-carrageenan, and both vitamin D and κ-carrageenan for 8 weeks after induction of oral cancer. At the end of the study, blood samples were obtained by cardiac puncture for determination of TNF-α and EGFR. Results: In the groups III and IV, serum EGFR showed significant low levels compared with Group I. In the Group VII, serum EGFR showed a significantly (p=0.014) low level compared with Group IV (614.3±69.7 pg/ml versus 882.4±45.6 pg/ml, respectively). Higher percentages of high levels of TNF-α were observed in the Groups VI and VII, while a lower percentage of EGFR was observed in the Group VI. Conclusion: both κ-carrageenan and vitamin D have antiproliferative effect against DMBA-inducing oral cancer by increasing the levels of TNF-α and suppressing the signaling pathway of EGFR. Concomitant using κ-carrageenan and vitamin D reduces the antiproliferative effect of each other. KeywordsOral cancer; 7, 12-dimethylbenz[a] anthracene; Vitamin D; κ-carrageenan; Epidermal growth factor receptor; Tumor necrosis factor-α.

Background: Nicotine is the active alkaloid in cigarettes. It was reported that tobacco smoking has many hazards; one of these hazards is the effect on the cognitive function of the prefrontal cortex. The aim of our study is to investigate the antioxidant effects of ginger, cinnamon oils, and their combination on morphological changes in the prefrontal cortex that were induced by nicotine. Materials and methods: Fifty adult male albino rats were divided into five groups: group I (control group), group II (nicotine), group III (nicotine + cinnamon), group IV (nicotine + ginger), and group V (nicotine + cinnamon + ginger). The coronal sections from the anterior part of the rat brain at the site of prefrontal cortex were examined by light microscope for (H&E and immunohistochemical staining with TNF-α and GFAP), while the ultrastructure morphology was examined by transmission electron microscopy. Levels of the oxidative stress markers (MDA, GSH) in the rats’ brain tissue homogenate were biochemically assessed. Results: Compared to the control group, the rats that were treated with nicotine (group II) showed a significant oxidative stress in the form of marked elevation of MDA and decrease in GSH, apoptotic changes especially in the pyramidal cells in the form of neuronal cell degeneration and pyknosis, and an elevation in the inflammatory marker TNF-α and GFAP expressions. These changes were observed to a lesser degree in rat group (III) and group (IV), while there was a marked improvement achieved by the combined usage of cinnamon and ginger oils, together compared to the nicotine group. Conclusions: Ginger and cinnamon are powerful antioxidants which ameliorate the degenerative and oxidative effects produced by nicotine on a rat’s prefrontal cortex.

In this study, the potential protective effect of aqueous extract of parsley (Petroselinum sativum) seeds against hydrogen peroxide (H2O2) – induced oxidative stress in male rats was assessed. Three groups of male albino rats were randomly divided (n=7) and were handled for twenty-eight days as follows: rats in group I served as control; animals in group || were provided with drinking water containing 0.5% H2O2 and those in group III received orally 8 mg/100 gm B.W. of aqueous extract of parsley seeds plus 0.5% H2O2 in drinking water. After four weeks experimental period, a significant increase in lipid peroxidation products (MDA), and decrease in glutathione (GSH) concentrations were observed in plasma, kidney, liver and heart tissues of H2O2 treated animals as compared with the control group. These biomarkers (GSH and MDA) are interrelated and indicate the occurrence of oxidative stress. Plasma total cholesterol (TC) concentration was significantly increased in H2O2 treated rats. By administration of aqueous extract of parsley along with H2O2, plasma and tissue GSH levels were significantly increased while the elevation in MDA level was diminished in plasma and different tissues examined. A decrease in plasma cholesterol concentration was recorded in H2O2 and parsley treated group as compared with the control one and H2O2 treated groups. These results indicate that aqueous extract of parsley have hypocholesterolemic and antioxidant effect.
