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.

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.

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.

<p>The aim of this study was to evaluate diuretic activity of aqueous methanolic extract of <em>Euphorbia granulate</em> in rats. Albino rats were divided into five groups. Group I served as reference, Group II as standard and Group III, IV and V served as test. The three doses of extract (30, 50 and 100 mg/kg) were given to rats (i.p) in acute diuretic model. Furosemide (10 mg/kg i.p) was used as standard drug. The extract induced diuretic effects and induced electrolytes excretion in a dose-dependent manner when compared with control. The extract (100 and 50 mg/kg) significantly (p&lt;0.01) increased the volume of urine in comparison to control group. Similarly, the excretion of potassium and sodium were also significantly (p&lt;0.05) increased following extract administration. However, there was no significant change in the pH of urine samples of the extract-treated group compared with control. The result of this study thus offers support to the traditional folker use of this plant as a diuretic agent.</p><p> </p>

The fact that cisplatin (CIS) can induce hepatotoxicity has limited its therapeutic uses, although it is recognised as a highly potent antineoplastic drug. Bee venom (BV) is an important toxin that exerts a potent anti-inflammatory effect and demonstrates significant pharmacological activities. The aim of this research was to investigate the therapeutic impact of BV administration orally on CIS-induced hepatotoxicity in a rat model when compared with individual drug therapy. Thirty albino male rats were used in this study. The rats were classified into three groups, each with ten rats (n = 10). The control group was group I, while groups II and III got CIS (a single dose of 7.5 mg/kg interperitoneally). After 24 hours, group III received BV (1 mg/kg orally), which was then administered daily for four weeks. The rats’ serum liver functions were estimated. The oxidative stress, antioxidant status, inflammatory mediators and fibrogenic and apoptotic markers were determined in the liver tissues. The results revealed that the administration of CIS induced a significant elevation in the serum aspartate aminotransferase, alanine aminotransferase and bilirubin levels, which was associated with a decrease in the albumin level. Additionally, significant increases in the hepatic tissue malondialdehyde, tumor necrosis factor alpha, interferon gamma, transforming growth factor beta, fibronectin and caspase-3 levels were noted. Moreover, significant decreases in the superoxide dismutase and catalase activities as well as the glutathione level were detected in the hepatic tissues. The administration of BV resulted in the notable amelioration of the aforementioned parameters. Interestingly, these parameters were restored to almost normal levels following administration of CIS and BV. The histopathological investigation revealed multiple focal inflammation sites that appeared to be associated with hepatic necrosis in the hepatic tissues of the CIS-treated rats. The co-administration of BV preserved the normal architecture of the hepatic tissues. These results indicate that the co-administration of BV exerts potent anti-hepatotoxic and cytoprotective effects by combating oxidative stress, inflammation, fibrogenic and apoptotic markers and histopathological changes. Thus, this study provides strong evidence of the superiority of combination drug therapy when compared with individual drug therapy.

Abstract Recently in many industries biologically synthesized silver nanoparticles are used as an alternative for their biomedicinal applications predominantly demonstrated as an effective agent in the diabetes treatment. On the other hand, oxidative stress crucially associated with the pathogenesis of diabetic comorbidities like diabetic hepatopathy, which is less common. Thus, the existing study explored the protective role of biologically synthesized silver nanoparticles (AV-AgNPs) against hepatic toxicity persuaded by streptozotocin (STZ) in rats. Wistar male albino rats (200 ± 20 g) were segregated into five groups (n=10) and designated as, Group I-Control (no treatment); Group II-Diabetic control (35 mg/kg single dose of streptozotocin, IP); Group III-Diabetic treated with AV-AgNPs (10 mg/kg); Group IV-Diabetic treated with aloe vera leaves extract (AVLE) (100 mg/kg); Group V-Diabetic treated with glibenclamide (GLB) (600 μg/kg) orally. After treatment of 28 days, animals were euthanized and collected blood and liver specimens for investigations of biochemical, oxidative stress, antioxidant, and histological parameters. Outcomes of the study exhibited that STZ persuades diabetes and hepatic impairments indicated by significant raised (p<0.05) in the levels of blood glucose, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, (ALP), and malondialdehyde (MDA) with decreased catalase (CAT), superoxide dismutase (SOD), and glutathione reductase (GSH) enzymes activities. AV-AgNPs treatment reverted and reestablished the liver enzymes levels, antioxidant enzymes, and histological damages of the liver persuaded by STZ near to normal. In general, these results suggested that AV-AgNPs may have antioxidant potentials and proved to be hepatoprotective therefore, they could be used for the treatment of diabetic hepatopathy and other liver injuries.

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.

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.
