Oyibo A, Abolaji AO, Omoboyowa DA, Odunola OA. Vitellaria paradoxa Inhibits Arsenic-induced Toxicity in Drosophila melanogaster Via the Augmentation of Antioxidant System. Toxicology 2023:153590. [PMID: 37421989 DOI: 10.1016/j.tox.2023.153590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 06/25/2023] [Accepted: 07/04/2023] [Indexed: 07/10/2023]
Abstract
The Ethyl Acetate Fraction (EACF) of Ethanol Leaf Extract of Vitellaria paradoxa (ELVp) was assessed against Sodium Arsenite (SA)-induced toxicity in Drosophila melanogaster. The Gas Chromatography-Mass Spectrometry (GC-MS) analysis of EACF was carried out. The molecular docking of the compounds obtained from GC-MS was performed against D. melanogaster glutathione-S-transferase-2 (GST-2). Firstly, D. melanogaster (Harwich strain) was treated with EACF to determine its effect on longevity. Secondly, D. melanogaster was fed with EACF (1.0 and 3.0 mg/5 g diet) and/or SA (0.0625 mM) for 5 days. Thereafter, the ameliorative role of EACF in SA-induced toxicity was evaluated using the fly's emergence rate, locomotor activity, oxidative stress and antioxidant biomarkers. The in-silico study revealed varying degrees of binding affinity of the twelve active compounds of EACF against GST-2 which was comparable with the co-crystalized ligand (glutathione). The EACF increased the longevity of D. melanogaster by 20.0% compared with control and ameliorated SA-induced reduction of emergence rate and locomotor performance by 178.2 and 20.5%, respectively. Additionally, EACF ameliorated SA-induced reduction of total thiol and non-protein thiols and inhibition of catalase and GST activities (p < 0.05). These results corroborated with histological data obtained in the fat body of D. melanogaster. Overall, EACF augmented the antioxidant system of D. melanogaster and prevented sodium arsenite-induced oxidative stress due to its high antioxidant property.

Mukherjee AG, Valsala Gopalakrishnan A. The interplay of arsenic, silymarin, and NF-ĸB pathway in male reproductive toxicity: A review. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 252:114614.

Abstract
Arsenic toxicity is one of the most trending reasons for several malfunctions, particularly reproductive toxicity. The exact mechanism of arsenic poisoning is a big question mark. Exposure to arsenic reduces sperm count, impairs fertilization, and causes inflammation and genotoxicity through interfering with autophagy, epigenetics, ROS generation, downregulation of essential protein expression, metabolite changes, and hampering several signaling cascades, particularly by the alteration of NF-ĸB pathway. This work tries to give a clear idea about the different aspects of arsenic resulting in male reproductive complications, often leading to infertility. The first part of this article explains the implications of arsenic poisoning and the crosstalk of the NF-ĸB pathway in male reproductive toxicity. Silymarin is a bioactive compound that exerts anti-cancer and anti-inflammatory properties and has demonstrated hopeful outcomes in several cancers, including colon cancer, breast cancer, and skin cancer, by downregulating the hyperactive NF-ĸB pathway. The next half of this article thus sheds light on silymarin's therapeutic potential in inhibiting the NF-ĸB signaling cascade, thus offering protection against arsenic-induced male reproductive toxicity.

Abstract
Arsenite (As) and fluoride (F), both of which are linked to a variety of human ailments, are regularly found in underground drinking water. Numerous studies have shown that As and/or F have negative impacts on testicular function and fertility. For this purpose, mouse Leydig cells, the main cells responsible for the generation and regulation of steroid hormones such as testosterone, were used to reveal the effects of individual and combined exposure of As and F on the steroidogenic pathway in the male reproductive system. Leydig cells were treated with 0.39 μM (50 ppb) As and 0.0476 mM (2 ppm) F alone and in combination for 24 h. The findings revealed that As and/or F exposure induced oxidative stress and apoptosis in Leydig cells and altered antioxidant equilibrium of the cells by reducing superoxide dismutase, catalase, glutathione peroxidase. Additionally, individual and combined administration of As and/or F significantly supressed the expression of both steroidogenic enzymes and the genes encoding these enzymes. In conclusion, this study showed that exposure to As and F at environmentally relevant concentrations dispersed by water decreased testosterone production in Leydig cells, an important cell of the male reproductive system. The deleterious effects of even the lowest concentrations of As and F elements that can reach humans from the environment on the Leydig cell, and therefore on male infertility, emphasize necessity new safe limits for these elements.

Abstract
Consumption of arsenic-contaminated drinking water has become major global health concern. One of the major mechanism responsible for the toxicity of arsenicals is the generation of oxidative stress. Zinc, a nutritional antioxidant, plays key role in maintaining various cellular pathways. The present study was aimed at elucidating the effects of zinc supplementation on hepatic and renal tissue damage caused by arsenic exposure to rats. Rats were randomly divided into four experimental groups: control; As administered; Zn supplemented; combined zinc; and arsenic supplemented. Arsenic exposure resulted in significantly elevated accumulation of arsenic in the liver and kidney tissue. In the liver, exposure to arsenic reduced the levels of reduced glutathione (GSH), total glutathione (TG), redox ratio, and the activity of superoxide dismutase (SOD), whereas lipid peroxidation (LPO), inflammation markers, and nitric oxide (NO) levels were elevated with no significant change in catalase (CAT) activity. Arsenic exposure also enhanced the serum levels of liver functional indices and histological abnormalities in liver sections. In the kidney, a significant increase in NO levels and decrease in SOD activity was observed, with no significant changes in the rest of the parameters. The administration of zinc- to arsenic-intoxicated animals significantly improved their hepatic function parameters, arsenic burden, and histological changes which were associated with the restoration of enzymatic and non-enzymatic antioxidant defense system as compared to their intoxicated counterparts. In the kidney also, the NO levels and SOD activity were restored. This data reveals that zinc is effective in ameliorating the toxic effects inflicted by chronic arsenic toxicity.

Abstract
Environmental and occupational exposures to heavy metals have led to various deleterious damages to the biological system of which infertility is one of them. Infertility is a global public health concern, affecting 15% of all couples of reproductive age. Out of the 100% cases of reported infertility among couples, 40% of the cases are related to male factors; including decreased semen quality. This review focuses on the recent mechanistic perspectives of heavy metal-induced male reproductive toxicity. The associated toxic metal-mediated mechanisms of male reproductive toxicity include ion mimicry, disruption of cell signaling pathways, oxidative stress, altered gene expression, epigenetic regulation of gene expression, apoptosis, disruption of testis/blood barrier, inflammation and endocrine disruption. The current literature suggests that non-coding RNAs (ncRNAs) mediate paternal intergenerational epigenetic inheritance and thus has a direct functional importance, as well as possess novel biomarker potential, for male reproductive toxicity. To identify the specific ncRNAs with the most profound impacts on heavy metal-induced male reproductive toxicity should be thrust of further research.

Abstract
The aim of the present study was to evaluate the basal concentrations of malondialdehyde (MDA) nonenzymatic antioxidants, such as ascorbic acid, α-tocopherol, and retinol in plasma or erythrocytes, and the plasma concentrations of 16 trace minerals in endurance athletes from Extremadura (Spain). In addition, we aimed to assess the possible relationships between some parameters related to cellular oxidative stress with plasma concentrations of some trace minerals. Sixty-two national long-distance men athletes participated in this study. The parameters related to oxidative stress and antioxidant activity were analyzed through high pressure liquid chromatography (HPLC), and trace minerals analysis was performed by inductively coupled plasma mass spectrometry (ICP-MS). We found that plasma MDA was positively correlated with selenium and rubidium. Plasma ascorbic acid was positively correlated with manganese and negatively correlated with cobalt and cadmium. Erythrocyte ascorbic acid was related to arsenic and cesium. Plasma α-tocopherol correlated with copper and manganese negatively and positively with arsenic. Erythrocyte α-tocopherol was positively related to copper, rubidium, and lithium. The findings show that athletes with a high degree of training should monitor their intake and concentrations of α-tocopherol for its fundamental role of neutralizing the excess of reactive oxygen species produced by exercise and the prooxidant effects of several minerals such as arsenic, copper, and lithium.

Abstract
Due to industrial and urban sewage, the metal contaminations in aquatic and terrestrial environments are increasing day by day, especially in developing countries. Despite the study of several years, we are inert far away from an actual medication for prolonged toxicity of heavy metals such as mercury, lead, cadmium etc. Lead is one of the most common heavy metals that possess toxicological effects on numerous tissues of animals as well as humans. Several toxic effects of lead on reproductive organs, renal system, central nervous system, liver, lungs, blood parameters, and bones have been reported. On the other hand, several reports depicted that garlic is operative in declining the absorption of lead in bones as well as soft tissues. A combination of vitamin C and vitamin E enhances the biological recovery induced by lead and mobilize the heavy metal such as lead from intra-cellular positions. This review provides therapeutic approaches such as vitamin C, vitamin E, and extract of garlic to treat the detrimental effects caused after the exposure of lead. These therapeutic strategies are beneficial for both the prevention and alleviation of lead noxiousness.

Abstract
Myeloid immune cells promote inflammation and fibrosis in chronic liver diseases. Drug delivery systems, such as polymers, liposomes and microbubbles, efficiently target myeloid cells in healthy liver, but their targeting properties in hepatic fibrosis remain elusive. We therefore studied the biodistribution of three intravenously injected carrier material, i.e. 10 nm poly(N-(2-hydroxypropyl)methacrylamide) polymers, 100 nm PEGylated liposomes and 2000 nm poly(butyl cyanoacrylate) microbubbles, in two fibrosis models in immunocompetent mice. While whole-body imaging confirmed preferential hepatic uptake even after induction of liver fibrosis, flow cytometry and immunofluorescence analysis revealed markedly decreased carrier uptake by liver macrophage subsets in fibrosis, particularly for microbubbles and polymers. Importantly, carrier uptake co-localized with immune infiltrates in fibrotic livers, corroborating the intrinsic ability of the carriers to target myeloid cells in areas of inflammation. Of the tested carrier systems liposomes had the highest uptake efficiency among hepatic myeloid cells, but the lowest specificity for cellular subsets. Hepatic fibrosis affected carrier uptake in liver and partially in spleen, but not in other tissues (blood, bone marrow, lung, kidney). In conclusion, while drug carrier systems target distinct myeloid cell populations in diseased and healthy livers, hepatic fibrosis profoundly affects their targeting efficiency, supporting the need to adapt nanomedicine-based approaches in chronic liver disease.

Abstract
Excessive amount of copper (Cu) and inorganic arsenic (iAs) coexists in drinking water in many regions, this is associated with high risk of nephropathy, defined as chronic structural and functional disorders of the kidney. However, the underlying mechanisms are not well understood. In this study, a total of 72 day-old Hy-line chickens were exposed to 300 mg/kg copper sulphate or/and 30 mg/kg arsenic trioxide for 12 weeks. Indicators of oxidative stress, inflammation and heat shock proteins (HSPs) production were analyzed in kidney. The results showed that, when the toxicant was administrated alone, there is an antagonism between redox homeostasis during the first 4 weeks, which follows a collapse of antioxidant system manifested by damaged biomembrane structure. What's worse, oxidative damage-cascaded histopathological lesions were accompanied by increases of proinflammatory mediators and an imbalance of "Th1/Th2 drift" (Th, helper T cell) regulated by nuclear factor kappa B (NF-κB). Simultaneously, intense heat shock response went with the organism. The above-mentioned renal lesions and indicators changes were time-dependent, more complex and deteriorated effects were observed in Cu/iAs combined groups compared with the others. This study supports Cu and iAs have a synergistic type on the nephro-toxicological process additively. In conclusion, oxidative stress and inflammatory induced by Cu or/and iAs are potential mechanisms in their nephrotoxicity, increased heat shock response may play a renoprotection function in tissues damage.

Abstract
INTRODUCTION Vitamins E and C are well known small molecules that have been used to maintain health for decades. Recent studies of the cellular and molecular pathways leading to immunomodulation by these molecules have been of interest, as have their anti-oxidant properties and signal transduction pathways for curing or improving infectious diseases and cancer. Areas covered: Herein, the authors provide a definition and the structural classification of vitamins E and C and how these molecules influence cellular function. The studies include in vitro, ex vivo and in vivo studies in animal models as well as clinical trials. The authors give particular focus to the scientifically factual and putative roles of these molecules in innate and adaptive immunomodulation and prevention or cure of diseases. Expert opinion: The antioxidant properties of vitamins E and C are well studied. However, whether there is a link between their antioxidant and immunomodulation properties is unclear. In addition, there is a strong, albeit putative, prevailing notion that vitamin C can prevent or cure infectious diseases or cancer. Presently, while there is proven evidence that vitamin E possesses immunomodulatory properties that may play a positive role in disease outcomes, this evidence is less available for vitamin C.

Abstract
The aim of the present study was to investigate the possible protective effects of boron, an antioxidant agent, against arsenic-induced oxidative stress in male and female rats. In total, 42 Wistar albino male and female rats were divided into three equal groups: The animals in the control group were given normal drinking water, the second group was given drinking water with 100 mg/L arsenic, and the third group was orally administered drinking water with 100 mg/kg boron together with arsenic. At the end of the 28-day experiment, arsenic increased lipid peroxidation and damage in the tissues of rats. However, boron treatment reversed this arsenic-induced lipid peroxidation and activities of antioxidant enzymes in rats. Moreover, boron exhibited a protective action against arsenic-induced histopathological changes in the tissues of rats. In conclusion, boron was found to be effective in protecting rats against arsenic-induced lipid peroxidation by enhancing antioxidant defense mechanisms.

Abstract
Arsenite directly triggers cytochrome c and Smac/DIABLO release in mitochondria isolated from U937 cells. These effects were not observed in mitochondria pre-exposed for 15 min to 10 µM L-ascorbic acid (AA). In other experiments, intact cells treated for 24-72 h with arsenite were found to die by apoptosis through a mechanism involving mitochondrial permeability transition. Pre-exposure (15 min) to low micromolar concentrations of AA and dehydroascorbic acid (DHA), resulting in identical cytosolic levels of the vitamin, had a diverse impact on cell survival, as cytoprotection was only observed after treatment with AA. Also the mitochondrial accumulation of the vitamin was restricted to AA exposure. An additional indication linking cytoprotection to the mitochondrial fraction of the vitamin was obtained in experiments measuring susceptibility to arsenite in parallel with loss of mitochondrial and cytosolic AA at different times after vitamin exposure. Finally, we took advantage of our recent findings that DHA potently inhibits AA transport to demonstrate that DHA abolishes all the protective effects of AA, under the same conditions in which the mitochondrial accumulation of the vitamin is prevented without affecting the overall cellular accumulation of the vitamin.

Abstract
Nanomedicine constitutes the emerging field of medical applications for nanotechnology such as nanomaterial-based drug delivery systems. This technology may hold exceptional potential for novel therapeutic approaches to liver diseases. The specific and unspecific targeting of macrophages, hepatic stellate cells (HSC), hepatocytes, and liver sinusoidal endothelial cells (LSEC) using nanomedicine has been developed and tested in preclinical settings. These four major cell types in the liver are crucially involved in the complex sequence of events that occurs during the initiation and maintenance of liver inflammation and fibrosis. Targeting different cell types can be based on their capacity to ingest surrounding material, endocytosis, and specificity for a single cell type can be achieved by targeting characteristic structures such as receptors, sugar moieties or peptide sequences. Macrophages and especially the liver-resident Kupffer cells are in the focus of nanomedicine due to their highly efficient and unspecific uptake of most nanomaterials as well as due to their critical pathogenic functions during inflammation and fibrogenesis. The mannose receptor enables targeting macrophages in liver disease, but macrophages can also become activated by certain nanomaterials, such as peptide-modified gold nanorods (AuNRs) that render them proinflammatory. HSC, the main collagen-producing cells during fibrosis, are currently targeted using nanoconstructs that recognize the mannose 6-phosphate and insulin-like growth factor II, peroxisome proliferator activated receptor 1, platelet-derived growth factor (PDGF) receptor β, or integrins. Targeting of the major liver parenchymal cell, the hepatocyte, has only recently been achieved with high specificity by mimicking apolipoproteins, naturally occurring nanoparticles of the body. LSEC were found to be targeted most efficiently using carboxy-modified micelles and their integrin receptors. This review will summarize important functions of these cell types in healthy and diseased livers and discuss current strategies of cell-specific targeting for liver diseases by nanomedicine.

Abstract
The present study investigates the possible ameliorative effects of diallyl trisulfide (DATS) against arsenic (As)-induced hepatotoxicity and oxidative stress in rats. The four experimental groups evaluated include: (1) vehicle control; (2) As (5 mg/kg/day); (3) DATS (80 mg/kg/day) + As; and (4) DATS. Induction of As in rats caused severe hepatotoxicity as evidenced by an elevation of serum aspartate aminotransferase and alanine aminotransferase activities and increased total bilirubin concentration, indicating hepatic function abnormalities. Histopathological examination revealed various structural changes in the liver, characterized by hepatocyte degeneration/necrosis, congestion, sinusoidal dilatation, vacuolation, and inflammatory cell infiltration. The significant decrease in reduced glutathione content, catalase, superoxide dismutase, glutathione peroxidase, and glutathione reductase activities and the significant increase in lipid peroxidation (thiobarbituric acid reactive substance) and protein oxidation (protein carbonyl) contents indicated that As-induced hepatotoxicity was mediated through oxidative stress. As intoxication also elevated the levels of Cas-3 and nitric oxide and increased the expression of nuclear factor-κB p65 in the liver. In contrast, DATS pretreatment significantly improved As-induced serum biochemical, immunohistochemical, and histopathological alterations reflecting hepatic dysfunction. These results may contribute to a better understanding of the hepatoprotective role of DATS, emphasizing the influence of this garlic trisulfide in the diet for human health, possibly preventing the hepatic injury associated with As intoxication, presumably due to its ability to inhibit lipid peroxidation, protein oxidation, and restoration of antioxidant status.

Abstract
Arsenic is one of the most hazardous substances in the environment known to cause toxicity in multiple organs. Cell adhesion, morphological alterations, cell proliferation, terminal deoxyuridine triphosphate nick-end labeling (TUNEL) and caspase-3/CPP32 fluorometric protease assay were important biomarkers to assess apoptosis in cells. This study aimed to evaluate arsenic-induced apoptosis in the hepatocytes of rat and its protective efficacy with coadministration of ascorbic acid (AA) and Pleurotus florida lectin (PFL) individually. Results of the present study also showed that arsenic caused cytotoxicity by elevating morphological alterations, TUNEL-positive nuclei, caspase-3 activity and DNA damage and reducing cell adhesion and cell proliferation in a time-dependent manner. The apoptosis in hepatocytes was reverted to normal value after coadministration of mushroom lectin in arsenic-exposed rat. The study provided significant evidence that PFL has antiapoptotic property against arsenic-induced toxicity. The beneficial effect of PFL was proportional to its duration of exposure. Retard activities of superoxide dismutase and catalase, enhanced lipid peroxidation as well as protein carbonyl in erythrocytes caused by arsenic could also be maintained toward normalcy by supplementation of AA and PFL. These antioxidative effects were exhibited in a time-dependant manner. In rat, treatment with AA and PFL prevented alteration of plasma enzyme activities caused by arsenic. The results concluded that treatment with PFL has significant role in protecting animals from arsenic-induced erythrocytic damage. This finding might be of therapeutic benefit in people suffering from chronic exposure to arsenic from natural sources, a global problem especially relevant to millions of people on the Indian subcontinent.

Abstract
This study was accomplished to exemplify the possible protective role of ascorbic acid and mushroom lectin against arsenic-induced cytotoxicity and impairment of superoxide dismutase (SOD) production pathway in hepatocytes of rat. Hepatocytes were isolated from rat and treated with sodium arsenite (AS), arsenic plus ascorbic acid (AS + AA) and arsenic plus mushroom lectin (AS + ML). A placebo control was also included. Arsenic treatment resulted in the depletion of cell proliferation, phagocytic activity (nitro blue tetrazolium index) and superoxide dismutase (SOD) activity, relative mRNA expression of superoxide dismutase 2 (SOD(2)) and enhanced production of nitric oxide (NO). Ascorbic acid, a standard antioxidant, could normalize cellular perturbation and SOD production pathway relating to gene expression, whereas partially purified Pleurotus florida lectin (PFL), an edible mushroom containing protein complex, maintained cellular activity and prevented stress by normalizing phagocytic (NBT index) and SOD activities vis-à-vis relative gene expression. It could further defend NO production of hepatocytes. Mushroom lectin strongly prevented sodium arsenite-induced damage of SOD production pathway in hepatocytes, and its effect was also comparable to a standard antioxidant, i.e. ascorbic acid.

Abstract
The protective effect of coenzyme Q10 against testicular toxicity induced by sodium arsenite (10mg/kg/day, orally for two consecutive days) was investigated in rats. Coenzyme Q10 treatment (10mg/kg/day, i.p.) was applied for five consecutive days, starting three days before arsenite administration. Coenzyme Q10 significantly increased serum testosterone level which was reduced by sodium arsenite. Coenzyme Q10 significantly suppressed lipid peroxidation, restored the depleted antioxidant defenses, and attenuated the increases of tumor necrosis factor-α and nitric oxide resulted from arsenic administration. Also, the elevation of arsenic ion, and the reductions of selenium and zinc ions in testicular tissue were mitigated by coenzyme Q10. Histopathological examination showed that testicular injury mediated by arsenic was ameliorated by coenzyme Q10 treatment. Immunohistochemical analysis revealed that coenzyme Q10 significantly decreased the arsenic-induced expression of inducible nitric oxide synthase, nuclear factor-κB, Fas ligand and caspase-3 in testicular tissue. It was concluded that coenzyme Q10 represents a potential therapeutic option to protect the testicular tissue from the detrimental effects of arsenic intoxication.

Abstract
Oyster mushroom, Pleurotus florida is regarded as one of the popular food with biopharmaceutical properties. Here, the study aimed to investigate the antioxidative effects of mushroom (Pleurotus florida) lectin against arsenic-induced nephrotoxicity in rats. Animals were divided into four groups; Group 1 was control. Groups 2, 3 and 4 were exposed to arsenic (20 parts per million [ppm] in drinking water), arsenic plus oral supplementation of ascorbic acid (25 mg/kg body weight) and arsenic plus oral supplementation of mushroom lectin (150 mg/kg body weight) respectively. Both ascorbic acid and mushroom lectin prevented the arsenic-mediated growth retardation and normalized the elevated kidney weight. Disrupted activities of superoxide dismutase (SOD) and catalase (CAT) and enhanced lipid peroxidation (LPO), protein carbonyl (PC) and nitric oxides (NO) production in kidney caused by arsenic could also be maintained towards normalcy by supplementation of mushroom lectin and ascorbic acid. These antioxidative effects were exhibited in a time-dependant manner. Further, arsenic-mediated down-regulation of messenger RNA (mRNA) expression of superoxide dismutase 2 (SOD2) gene was obstructed by these agents. Thus it was found that mushroom lectin reversed the effect of arsenic-mediated oxidative stress in a time-dependent manner.

Abstract
This study aimed to determine the hemato-biochemical picture and blood oxidative stress in zebu cattle in an arsenic-contaminated zone. Significant decline in total erythrocyte count, packed cell volume, and total plasma protein was observed in cattle of that area in comparison to uncontaminated zone. There was significant elevation of plasma enzyme activities of both alanine aminotransaminase and aspertate aminotransaminase. Increased corpuscular osmotic fragility also proved to be a mechanism for deviation from normal functioning of erythrocytes. Cattle in the affected zone showed a significantly higher arsenic burden in blood. Those animals further showed decreased superoxide dismutase, catalase activities of erythrocytes, and plasma nitrite level, but increased lipid peroxidation and protein carbonyl level. Our finding concluded that cattle of the arsenic-contaminated zone is suffering from a subclinical form of arsenic toxicity, which is proved through altered hemato-biochemical indices and a certain extent of oxidative stress with higher arsenic concentration in blood.

Abstract
Oxidative stress due to arsenic toxicity and ameliorative potentiality of L-ascorbic acid was evaluated in an ex vivo system of rat hepatic tissue. The study revealed that arsenic increased the activity of superoxide dismutase (SOD) and catalase (CAT) and the level of lipid peroxidation (LPO), protein carbonyl (PC) and nitric oxide (NO) at 1 hour, 1.5 hours and 2 hours of incubation. Co-treatment with L-ascorbic acid was found effective to normalize the activity of SOD and CAT and the production of LPO, PC and NO in hepatic tissue. This ex vivo study suggested that ascorbic acid is helpful to ameliorate arsenic-induced oxidative stress. This may be one of the alternative screening systems to study the efficacy of antioxidant and hepatoprotective agent.
