[PMID: 36933876 DOI: 10.1016/j.jep.2023.116352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 02/14/2023] [Accepted: 03/01/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia arjuna (Roxb. ex DC.) Wight & Arnot (Combretaceae) is one of the most frequently used medicinal trees in Indian traditional medicinal systems. It is used for the treatment of a variety of diseases including cardiovascular disorders. AIM OF THE STUDY The purpose of this review was to provide a comprehensive overview of the phytochemistry, medicinal uses, toxicity, and industrial applications of T. arjuna bark (BTA), as well as to identify gaps in research and applications of this important tree. It also aimed to analyze trends and future research paths to utilize the full potential of this tree. MATERIALS AND METHODS Extensive bibliographic research on the T. arjuna tree was carried out using scientific research engines and databases such as Google Scholar, PubMed, and Web of Science, covering all relevant English-language articles. The database "World Flora Online (WFO)" (http://www.worldfloraonline.org) was used to confirm plant taxonomy. RESULTS To date, BTA has been traditionally employed for several disorders such as snakebites, scorpion stings, gleets, earaches, dysentery, sexual disorders, and urinary tract infections along with the cardioprotective activity. About 38 phytocompounds were identified from BTA and were classified as triterpenoids, tannins, flavonoids, and glycosides. A wide range of in vitro and in vivo pharmacological effects of BTA were reported such as anti-cancer, antimicrobial, antiviral, anti-inflammatory, antioxidant, hepatoprotective, anti-allergic, anti-diabetic, and wound healing activities. The oral administration of BTA (500 mg/kg) per day did not result in any toxicity in humans. The in vivo acute and sub-acute toxicity analysis of the methanol extract of BTA and one of its major compounds, 7-methyl gallate, did not produce any adverse effects up to a dose of 1000 mg/kg. CONCLUSIONS This comprehensive review highlights various aspects of traditional knowledge, phytochemicals, and pharmacological significance of BTA. The review covered safety information on employing BTA in pharmaceutical dosage forms. Despite its long history of medicinal benefit, more studies are needed to understand the molecular mechanisms, structure-activity relationship, and potential synergistic and antagonistic effects of its phytocompounds, drug administration, drug-drug interactions, and toxicological effects.

Attenuation of fluoride-induced hepatorenal oxidative stress by ferulic acid in vivo: An approach with in-silico analysis and interaction informatics of ferulic acid. J Trace Elem Med Biol 2023; 77:127133. [PMID: 36638706 DOI: 10.1016/j.jtemb.2023.127133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 01/06/2023] [Accepted: 01/08/2023] [Indexed: 01/11/2023]
Abstract
BACKGROUND Chronic fluoride toxicity induces oxidative strain and lipid peroxidation and imparts deleterious effects on human metabolic organs. AIM The present study aimed to expose the defensive impact of ferulic acid against sodium fluoride (NaF) induced hepatorenal dysfunction at the biochemical and antioxidative systems. METHODS In-vivo. Rats were arbitrarily separated into five groups as control, sodium fluoride-treated (200 ppm kg -1), vitamin C -as a positive control, and FA co-administered groups with 10 mg kg -1 and 20 mg kg -1 body weight for 56 days. In the present investigation, we measured antioxidant enzymes, superoxide dismutase, catalase, and lactate dehydrogenase by electrozymographic and spectrophotometric methods. Biochemical assessment of TBARS, conjugated diene, and different serum biomarkers was done for liver and kidney functionality tests. In-silico. An in-silico study was conducted through a molecular docking experiment to evaluate the binding potentiality of FA by employing AutoDock Vina [version 1.5.6] to overcome the abnormality in the activities of catalase, and superoxide dismutase in NaF promoted toxicity of hepatorenal system. In-vitro. An in vitro biochemical experiment was conducted to support the in-silico study. RESULTS Superoxide dismutase and catalase were decreased in the intoxicated rat. Ferulic acid (FA) as an antioxidant remarkably defended the NaF-mediated deterioration of the antioxidative status in the hepatorenal system, lowering lipid peroxidation products, malondialdehyde, and conjugated diene. Serum biomarkers, ALT, AST, ALP, urea, and creatinine increased in the intoxicated group than in control. Ferulic acid significantly neutralized the ill effects of NaF on serum lipid profile. In-silico analysis hypothesized the strong interaction of FA with the active side of catalase and superoxide dismutase that prevented the binding of NaF at the active site of these mentioned enzymes and this was further validated by in-vitro assay. CONCLUSION However, FA modulates free radical generation and protected these metabolic organs against sodium fluoride-induced injury.

Antioxidant and Antithrombotic Activities of Kenaf Seed (Hibiscus cannabinus) Coat Ethanol Extract in Sprague Dawley Rats. Appl Biochem Biotechnol 2023; 195:772-800. [PMID: 36173546 DOI: 10.1007/s12010-022-04144-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/28/2022] [Indexed: 01/24/2023]
Abstract
Oxidative stress has been implicated in deadly lifestyle diseases, and antioxidants from plant sources are the primary option in the treatment regime. Kenaf seeds are the storehouse of potential natural antioxidant phytoconstituents. Perhaps, none of the studies documented the phytoconstituents and their antioxidant potential from Kenaf seed coat so far. Thus, the current study focuses on exploring the protective effect of Kenaf Seed Coat Ethanol Extract (KSCEE) against sodium nitrite and diclofenac-induced oxidative stress in vitro (red blood cell and platelets model) and in vivo (female Sprague Dawely rat's model) along with the antithrombotic activity. The infrared spectrophotometry data showed the heterogeneous functional groups (CH, OH, C = C, C = C-C) and aromatic rings. Reverse phase high-performance liquid chromatography and gas chromatography-mass spectrometry chromatogram of KSCEE also evidenced the presence of several phytochemicals. KSCEE displayed about 76% of DPPH scavenging activity with an IC50 value of 34.94 µg/ml. KSCEE significantly (***p < 0.001) normalized the stress markers such as lipid peroxidation, protein carbonyl content, superoxide dismutase, and catalase in sodium nitrite and diclofenac-induced oxidative stress in RBC, platelets, liver, kidney, and small intestine, respectively. Furthermore, KSCEE was found to protect the diclofenac-induced tissue destruction of the liver, kidney, and small intestine obtained from seven groups of female Sprague Dawely rats. KSCEE delayed the clotting time of platelet-rich plasma and platelet-poor plasma and activated partial thromboplastin time, suggesting its anticoagulant property. In addition, KSCEE also exhibited antiplatelet activity by inhibiting both adenosine diphosphate and epinephrine-induced platelet aggregation. In conclusion, KSCEE ameliorates the sodium nitrite and diclofenac-induced oxidative stress in red blood cells, platelets, and experimental animals along with antithrombotic properties.

Abstract
Diabetes is a common metabolic disorder marked by unusually high plasma glucose levels, which can lead to serious consequences such as retinopathy, diabetic neuropathy and cardiovascular disease. One of the most efficient ways to reduce postprandial hyperglycemia (PPHG) in diabetes mellitus, especially insulin-independent diabetes mellitus, is to lower the amount of glucose that is absorbed by inhibiting carbohydrate hydrolyzing enzymes in the digestive system, such as α-glucosidase and α-amylase. α-Glucosidase is a crucial enzyme that catalyzes the final stage of carbohydrate digestion. As a result, α-glucosidase inhibitors can slow D-glucose release from complex carbohydrates and delay glucose absorption, resulting in lower postprandial plasma glucose levels and control of PPHG. Many attempts have been made in recent years to uncover efficient α-glucosidase inhibitors from natural sources to build a physiologic functional diet or lead compound for diabetes treatment. Many phytoconstituent α-glucosidase inhibitors have been identified from plants, including alkaloids, flavonoids, anthocyanins, terpenoids, phenolic compounds, glycosides and others. The current review focuses on the most recent updates on different traditional/medicinal plant extracts and isolated compounds' biological activity that can help in the development of potent therapeutic medications with greater efficacy and safety for the treatment of type 2 diabetes or to avoid PPHG. For this purpose, we provide a summary of the latest scientific literature findings on plant extracts as well as plant-derived bioactive compounds as potential α-glucosidase inhibitors with hypoglycemic effects. Moreover, the review elucidates structural insights of the key drug target, α-glucosidase enzymes, and its interaction with different inhibitors.

Abstract
Fluoride is an important trace element in the living body. A suitable amount of fluoride has a beneficial effect on the body, but disproportionate fluoride entering the body will affect various organs and systems, especially the liver, kidneys, nervous system, endocrine system, reproductive system, bone, and intestinal system. In recent years, with the rapid development of agriculture and industry, fluoride pollution has become one of the important factors of environmental pollution, and fluoride pollution in any form is becoming a serious problem. Although countries around the world have made great breakthroughs in controlling fluoride pollution, however fluorosis still exists. A large amount of fluoride accumulated in animals will not only produce the toxic effects, but it also causes cell damage and affect the normal physiological activities of the body. There is no systematic description of the damage mechanism of fluoride. Therefore, the study on the toxicity mechanism of fluoride is still in progress. This review summarizes the existing information of several molecular mechanisms of the fluoride toxicity comprehensively, aiming to clarify the toxic mechanism of fluoride on various body systems. We have also summerized the pathological changes of those organ systems after fluoride poisoning in order to provide some ideas and solutions to the reader for the prevention and control of modern fluoride pollution.

Abstract
Fluorosis is a major public health problem globally. The non-availability of specific treatment and the irreversible nature of dental and skeletal lesions poses a challenge in the management of fluorosis. Oxidative stress is known to be one of the most important mechanisms of fluoride toxicity. Fluoride promotes the accumulation of reactive oxygen species by inhibiting the activity of antioxidant enzymes, resulting in the excessive production of reactive oxygen species at the cellular level which further leads to activation of cell death processes such as apoptosis. Phytochemicals that act as antioxidants have the potential to protect cells from oxidative stress. Evidence confirms that clinical symptoms of fluorosis can be mitigated to some extent or prevented by long-term intake of antioxidants and plant products. The primary purpose of this review is to examine recent findings that focus on the amelioration of fluoride-induced oxidative stress and apoptosis by natural and synthetic phytochemicals and their molecular mechanisms of action.

Abstract
OBJECTIVES Cynometra travancorica, endemic to Western Ghats of India is pharmacologically similar to Saraca asoca and occasionally used as substitute in a well-known Ayurvedic uterine tonic Asokarishta. S. asoca possess various biological properties, but there are no reports on C. travancorica. The present study evaluated the pharmacological properties of C. travancorica and its efficacy in attenuating the sodium fluoride (NaF) induced oxidative stress in mice. METHODS Antioxidant potential of methanolic extract of C. travancorica (CTE) stem bark was evaluated using DPPH, superoxide radical scavenging and total antioxidant assays. The effect of CTE on mitigating NaF deteriorated redox status in the liver tissue of mice was evaluated. Functional groups in CTE were analyzed by FTIR analysis. RESULTS CTE effectively scavenged the free radicals in in vitro condition. CTE could augment catalase (46.6%), superoxide dismutase (53.8%) activities and GSH level (48.1%) against NaF induced decline in the liver tissue of mice. The peroxidation of lipids was found to be decreased by 44.9% and tissue damage abated as inferred by histopathology. FTIR analysis revealed the presence of biologically active functional groups in CTE. CONCLUSIONS The study revealed the ameliorative effect of C. travancorica against NaF induced deleterious effect in experimental animals by its potent antioxidant potential.

Abstract
The present study is dedicated to development of improved method for determination of trace amounts of fluorides in natural waters which is based on the interaction of fluorides with ion associate (IA) of Al(III), salicylic aldehyde acylhydrazones (benzhydrazone (SABH) and 4-picolinhydrazone (SAPH)) and polymethine dye Astra Phloxine FF (AP). Comparison of analytical forms [Al(SABH)2]⋅AP and [Al(SAPH)2]⋅AP showed that the analytical system Al(III)-SAPH-AP is more effective, namely, a higher level of preconcentration of the analytical form is ensured by and extraction equilibrium is achieved faster. Based on the study, we propose a new, fast, simple, reliable, sensitive, and accurate method of the indirect UV-Vis-spectrophotometric determination of fluorides grounded on the interaction of fluorides with IA of Al(III), SAPH and AP with the utilization of vortex-assisted liquid-liquid microextraction (VALLME). The method is based on the discoloration of the microextract of IA of Al(III), SAPH and AP (Al-SAPH-AP) in presence of fluoride ions due to the formation of fluoride complexes of aluminum with higher stability. The effect of various factors has been studied. The optimal conditions of the UV-Vis-spectrophotometric determination of fluorides were defined as: pH 7.0-10.0, 1.0⋅10-6 mol⋅L-1 Al(III); 4.0⋅10-5 mol⋅L-1 SAPH; 1.0⋅10-6 mol⋅L-1 AP; λ = 560 nm. VALLME have been carried out in 250 μL of CCl4 at 20:1 vol ratios of aqueous and organic phases, with vortexing at 3000 rpm for 15 s followed by centrifugation at 2000 rpm for 2 min. The determination of fluorides is feasible in the presence of various interferences. The calibration curve shows the linear dependence in the range of 0.3-114 μg⋅L-1 of the fluorides concentration (R2 = 0.993) with the limit of detection of 0.086 μg⋅L-1 and the limit of determination of 0.284 μg⋅L-1. The accuracy of the proposed protocol of fluorides determination was verified towards a reference method on the samples of natural rivers waters (RSD 2.6-3.1%, recovery 98.3-101.4%).

Abstract
Recently the use of bioactive α-glucosidase inhibitors for the treatment of diabetes have been proven to be the most efficient remedy for controlling postprandial hyperglycemia and its detrimental physiological complications, especially in type 2 diabetes. The carbohydrate hydrolysing enzyme, α-glucosidase, is generally competitively inhibited by the α-glucosidase inhibitors and results in the delayed glucose absorption in small intestine, ultimately controlling the postprandial hyperglycemia. Here we have reviewed the most recent updates in the bioactive α-glucosidase inhibitors category. This review provides an overview of the α-glucosidase inhibitory potentials and efficiency of controlling postprandial hyperglycemia of various bioactive compounds such as flavonoids, phenolic compound, polysaccharide, betulinic acid, tannins, anthocyanins, steroids, polyol, polyphenols, galangin, procyanidins, hydroxyl-α-sanshool, hydroxyl-β-sanshool, erythritol, ganomycin, caffeoylquinic acid, resin glycosides, saponins, avicularin, oleanolic acids, urasolic acid, ethanolic extracts etc., from various dietary and non-dietary naturally occurring sources.

Abstract
Concentrated pomegranate peel extract (CPE) was supplemented to ewes, and milk yield and fat content-fatty acid (FA) and phospholipid (PL) composition-were monitored. CPE-fed ewes had higher milk yield, and fat, protein and lactose contents than controls. Milk PL content-20% higher in the CPE-supplemented group-was regulated by treatment and not by total fat content; milk phosphatidylethanolamine and phosphatidylcholine increased by 22 and 26%, respectively, in CPE-supplemented vs. control ewes. Milk saturated FA concentration was higher, and total polyunsaturated and monounsaturated FA content lower in the CPE vs. control group, regardless of milk total fat content. CPE supplementation increased milk antioxidant capacity, suggesting antioxidant transfer from dietary source to milk, increasing stability and nutritive value. Our study provides first evidence for milk quality improvement in terms of antioxidants and PL enrichment without compromising total milk fat, suggesting strategies to improve dairy animals' milk composition without compromising total production.

Abstract
The most preferable mode of drugs administration is via the oral route but physiological barriers such as pH, enzymatic degradation etc. limit the absolute use of this route. Herein lies the importance of nanotechnology having a wide range of applications in the field of nano-medicine, particularly in drug delivery systems. The exclusive properties particularly small size and high surface area (which can be modified as required), exhibited by these nanoparticlesrender these structures more suitable for the purpose of drug delivery. Various nanostructures, like liposomes, dendrimers, mesoporous silica nanoparticles, etc. have been designed for the said purpose. These nanostructures have several advantages over traditional administration of medicine. Apart from overcoming the pharmacokinetic and pharmacodynamics limitations of many potential therapeutic molecules, they may also be useful for advanced drug delivery purposes like targeted drug delivery, controlled release, enhanced permeability and retention (EPR) effect. In this review, we attempt to describe an up-to-date knowledge on various strategically devised nanostructures to overcome the problems related to oral drug administration.

Abstract
Arsenic contaminated drinking water consumption is a serious health issue around the world. Chronic inorganic arsenic exposure has been associated with respiratory dysfunctions. It exerts various detrimental effects, disrupting normal cellular homeostasis and turning on severe pulmonary complications. This study elucidated the role of mangiferin, a natural xanthone, against arsenic induced lung toxicity. Chronic exposure of sodium arsenite (NaAsO2) at 10 mg/kg bw for 3 months abruptly increased the LDH release in broncho-alveolar lavage fluid, generated reactive oxygen species (ROS), impaired the antioxidant defense and distorted the alveoli architecture. It caused significant inflammatory outburst and promoted the apoptotic mode of cell death via upregulating the expressions of various proapoptotic molecules related to mitochondrial, extra-mitochondrial and ER stress mediated apoptotic pathway. Activation of inflammatory cascade led to disruption of alveolar capillary barrier and impaired Na+/K+-ATPase function that led to detaining of alveolar fluid clearance activity. Mangiferin due to its anti-inflammatory activity suppressed this inflammation and reduced inflammatory cell infiltration in lung tissue. It significantly restored the antioxidant balance and inhibited apoptosis in lung via upregulating Nrf2-HO1 axis.

Abstract
Oxidative insult, inflammation, apoptosis and autophagy play a pivotal role in the etiology of diabetic nephropathy, a global health concern. Ferulic acid, a phytochemical, is reported to protect against varied diseased conditions. However, the ameliorative role and mechanisms of ferulic acid in averting STZ-mediated nephrotoxicity largely remains unknown. For in vivo study, a single intraperitoneal injection of streptozotocin (50 mg kg-1 body wt.) was administered in experimental rats to induce diabetes. The diabetic rats exhibited a rise in blood glucose level as well as kidney to body weight ratio, a decrease in serum insulin level, severe kidney tissue damage and dysfunction. Elevation of intracellular ROS level, altered mitochondrial membrane potential and cellular redox balance impairment shown the participation of oxidative stress in hyperglycemia-triggered renal injury. Treatment with ferulic acid (50 mg kg-1 body wt., orally for 8 weeks), post-diabetic induction, could markedly ameliorate kidney injury, renal cell apoptosis, inflammation and defective autophagy in the kidneys. The underlying mechanism for such protection involved the modulation of AGEs, MAPKs (p38, JNK, and ERK 1/2), NF-κB mediated inflammatory pathways, mitochondria-dependent and -independent apoptosis as well as autophagy induction. In cultured NRK-52E cells, ferulic acid (at an optimum dose of 75 μM) could counter excessive ROS generation, induce autophagy and inhibit apoptotic death of cells under high glucose environment. Blockade of autophagy could significantly eradicate the protective effect of ferulic acid in high glucose-mediated cell death. Together, the study confirmed that ferulic acid, exhibiting hypoglycemic, antioxidant, anti-inflammatory, anti-apoptotic activities and role in autophagy, could circumvent oxidative stress-mediated renal cell damage.

Abstract
One of the major consequences of diabetes is reproductive dysfunction but the fundamental mechanisms are still poorly known. The objective of the present study was to explore the beneficial role of taurine against streptozotocin induced testicular dysfunctions in diabetic male Wister rats and understanding the underlying intricate molecular mechanisms. Exposure to streptozotocin (50 mg kg-1 body weight, i.p., once) elevated blood glucose level, induced testicular histological alterations and reduced testis-to-body weight ratio, serum testosterone, testicular markers and activity of antioxidant enzymes. Generation of ER stress (increased expression of calpain-1, caspase-12 and upregulation of CHOP, GRP78 via eIF2α signaling), translocation of NF κB in the nucleus (leading to the upregulation in the levels of inflammatory cytokines), activation of mitochondria dependent apoptotic pathway and DNA fragmentation were revealed from this study. However, administration of taurine at a dose of 100 mg kg-1 body weight for 6 weeks post diabetic induction, successfully ameliorated all these adverse effects. Thus, taurine, as a potential therapeutic agent, may hold promise in preventing oxidative and ER stress mediated diabetic testicular complications in rats.

Abstract
This study was designed to evaluate the effect of rutin on hepatotoxicity induced by thioacetamide (TAA) in rats. Four groups of male Wistar rats consisting of six rats each were used: Group I: control group; Group II: rats receiving single injection of 300 mg kg−1 body weight of TAA intraperitoneally; Group III: rats administered rutin (10 mg kg−1 body weight) dissolved in saline orally for 2 weeks; and Group IV: rats administered rutin (10 mg kg−1 body weight) dissolved in saline orally for 2 weeks followed by TAA injection last day of second week. All groups were sacrificed after 24 h of treatment and hepatic toxicity was analyzed with respect to liver toxicity markers, liver DNA fragmentation, and histology of liver tissue. Administration of TAA in Wistar rats resulted in significant increase of hepatic markers, DNA fragmentation in the hepatocytes, and changes in histology. Pretreatment of rats with rutin before 2 weeks of TAA assault resulted in the complete reversal of TAA-mediated hepatic toxicity (P < 0.0001 to P < 0.01) with concomitant restoration of DNA fragmentation. This study suggests rutin as a protective agent for restoration of toxicity caused by TAA.

Abstract
The present study has been conducted to explore a novel strategy to modulate the unfavourable effects of indomethacin by Phyllanthus niruri protein (PNP) and the underlying mechanism PNP exploits for the amelioration of that pathophysiology. In hepatocytes, indomethacin enhanced reactive oxygen species (ROS), reduced intracellular antioxidant capacity, up regulated mitogen activated protein kinase (MAPKs), disrupted mitochondrial membrane potential, activated apoptotic pathways and there by reduced the viability of the hepatocytes. Simultaneous treatment with PNP modulated these detrimental actions of the drug and retained cell viability. Similarly, in mice, indomethacin elevated serum marker enzymes (e.g. Alanine Transaminase), decreased antioxidant enzyme activities, elevated oxidations of lipids and proteins, increased intracellular calcium overload mediated endoplasmic reticular stress (ER stress) pathways, up regulated the pro-inflammatory cytokines and there by leading to the mitochondrial dependent caspase-3 activation and poly-ADP ribose polymerase (PARP) cleavage. Moreover investigation of these inherent molecular pathways exhibited that these alterations are associated with up regulation of MAPKs, inducible nitric oxide synthase (iNOS), heme oxygenase-1 and down regulation of survival proteins. However, PNP suppressed those apoptotic indices as evidenced from histopathological studies and DNA fragmentation analysis. Combining, results suggest that PNP could possibly provide a protection against indomethacin-induced hepatic pathophysiology.

Abstract
Silymarin (SMN) has been shown to possess a wide range of biological and pharmacological effects. Besides, SMN has antioxidant and free radical scavenging activities. Thioacetamide (TAA) is a well-documented liver toxin that requires oxidative bioactivation to elicit its hepatotoxic effect which ultimately modifies amine-lipids and proteins. Our study has been designed in a TAA exposed mouse model to investigate whether SMN could protect TAA-induced oxidative stress mediated hepatic and renal damage. Results suggest that TAA generated reactive oxygen species (ROS), caused oxidative stress and induced apoptosis in the liver and kidney cells via JNK as well as PKC and MAPKs signaling. All these detrimental effects of TAA could, however, be suppressed by SMN which not only scavenged ROS but also induced PI3K-Akt cell survival pathway in the liver and prevented apoptotic pathways in both the organs. Histological studies, collagen staining and DNA fragmentation analysis also supported our results. Combining, we say that SMN possess beneficial role against TAA mediated hepatic and renal pathophysiology.

Abstract
Terminalia arjuna (Ta) bark contains various natural antioxidants and has been used to protect animal cells against oxidative stress. In the present study, we have examined alleviating effects of Ta bark aqueous extract against Ni toxicity in rice (Oryza sativa L.). When rice seedlings were raised for 8 days in hydroponics in Yoshida nutrient medium containing 200 μM NiSO4, a decline in height, reduced biomass, increased Ni uptake, loss of root plasma membrane integrity, increase in the level of O2˙-, H2O2 and ˙OH, increased lipid peroxidation, decline in photosynthetic pigments, increase in the level of antioxidative enzymes superoxide dismutase, catalase and glutathione peroxidase and alterations in their isoenzyme profile patterns were observed. Transmission electron microscopy (TEM) showed damage to chloroplasts marked by disorganised enlarged starch granules and disrupted thylakoids under Ni toxicity. Exogenously adding Ta bark extract (3.2 mg ml-1) to the growth medium considerably alleviated Ni toxicity in the seedlings by reducing Ni uptake, suppressing generation of reactive oxygen species, reducing lipid peroxidation, restoring level of photosynthesis pigments and ultrastructure of chloroplasts, and restoring levels of antioxidative enzymes. Results suggest that Ta bark extract considerably alleviates Ni toxicity in rice seedlings by preventing Ni uptake and reducing oxidative stress in the seedlings.

In the present study, a series of twenty-two (22) synthetic 3,3'-(aryl/alkyl-methylene)bis(2-hydroxynaphthalene-1,4-dione) bis-lawsone derivatives were assayed for their pro-apoptotic activity in six different cell lines (five cancerous and one normal) using MTT assay. Out of these 22 test compounds, 1j was found to be the most effective in inducing apoptosis in human glioma cells (CCF-4) among the different cell lines used in the study. The activity of this compound, 1j, was then compared to a popular anticancer drug, cisplatin, having limited usage because of its nephrotoxic nature. In this study, 1j derivative showed much less toxicity to the normal kidney cells compared to cisplatin, thus indicating the superiority of 1j as a possible anticancer agent. This compound was observed to induce apoptosis in the glioma cells by inducing the caspase dependent apoptotic pathways via ROS and downregulating the PI3K/AKT/mTOR pathway. Estimation of different oxidative stress markers also confirms the induction of oxidative stress in 1j exposed cancer cells. The toxicity of 1j compound toward cancer cells was confirmed further by different flow cytometrical analyses to estimate the mitochondrial membrane potential and cell cycle. The sensitivity of malignant cells to apoptosis, provoked by this synthetic derivative in vitro, deserves further studies in suitable in vivo models. These studies not only identified a novel anticancer drug candidate but also help to understand the metabolism of ROS and its application in cancer treatment.

Biochem Biophys Rep 2016; 5:313-327. [PMID: 28955838 PMCID: PMC5600319 DOI: 10.1016/j.bbrep.2016.01.011] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2015] [Revised: 12/28/2015] [Accepted: 01/12/2016] [Indexed: 12/19/2022] Open
Abstract
Background Mangiferin is a polyphenolic xanthonoid with remarkable antioxidant activity. Oxidative stress plays the key role in tert-butyl hydroperoxide (tBHP) induced renal cell damage. In this scenario, we consider mangiferin, as a safe agent in tBHP induced renal cell death and rationalize its action systematically, in normal human kidney epithelial cells (NKE). Methods NKE cells were exposed to 20 µM mangiferin for 2 h followed by 50 µM tBHP for 18 h. The effect on endogenous ROS production, antioxidant status (antioxidant enzymes and thiols), mitochondrial membrane potential, apoptotic signaling molecules, PI3K mediated signaling cascades and cell cycle progression were examined using various biochemical assays, FACS and immunoblot analyses. Results tBHP exposure damaged the NKE cells and decreased its viability. It also elevated the intracellular ROS and other oxidative stress-related biomarkers within the cells. However, mangiferin dose dependently, exhibited significant protection against this oxidative cellular damage. Mangiferin inhibited tBHP induced activation of different pro-apoptotic signals and thus protected the renal cells against mitochondrial permeabilization. Further, mangiferin enhanced the expression of cell proliferative signaling cascade molecules, Cyclin d1, NFκB and antioxidant molecules HO-1, SOD2, by PI3K/Akt dependent pathway. However, the inhibitor of PI3K abolished mangiferin's protective activity. Conclusions Results show Mangiferin maintains the intracellular anti-oxidant status, induces the expression of PI3K and its downstream molecules and shields NKE cells against the tBHP induced cytotoxicity. General significance Mangiferin can be indicated as a therapeutic agent in oxidative stress-mediated renal toxicity. This protective action of mangiferin primarily attributes to its potent antioxidant and antiapoptotic nature. Mangiferin relives oxidative stress on tBHP induced renal cytotoxicity. Mangiferin reduces tBHP-induced renal cell apoptosis. PI3K has been found to be the pivotal target of mangiferin. Mangiferin positively regulates cell cycle by modulating GSK3β and cyclin D1.

Abstract
BACKGROUND Cisplatin is a potent anti-tumor compound. Nephrotoxicity-inducing oxidative stress is a common side effect. This study was conducted to find out whether, the triterpenoid saponin of Terminalia arjuna (TA), Arjunolic acid which is a natural antioxidant, could prevent cisplatin-induced renal toxicity and if so, explore its possible renoprotective mechanism. METHODS Thirty male Sprague-Dawley rats were divided into three groups: CONTROL GROUP rats received saline injection, cisplatin group: rats injected intraperitoneally with 7 mg/kg cisplatin and Arjunolic acid group: rats received 20 mg/kg Arjunolic acid daily for 10 days with cisplatin injection on day 5. Serum creatinine and blood urea nitrogen (BUN) were determined and kidney sections were obtained for histopathology. Oxidative stress was evaluated in kidney homogenates by measuring malondialdehyde (MDA), reduced glutathione (GSH) and nitric oxide (NO) levels. Renal gene expressions of transforming growth factor-beta (TGF-β), nuclear factor-kappa B (NF-κB), kidney injury molecule-1 (Kim-1) and B cell lymphoma-2 (Bcl-2) were estimated. RESULTS Cisplatin-treated rats showed a significant reduction in renal GSH and a significant elevation of serum creatinine, BUN, MDA and NO renal levels when compared with control. Moreover, upregulation of TGF-β, NF-κB and Kim-1 along with downregulation of Bcl-2 renal expressions were also observed in cisplatin-treated rats in comparison to control. All these markers were significantly reversed by TA triterpenoid saponin administration. CONCLUSION Arjunolic acid ameliorated the nephrotoxic biochemical changes induced by cisplatin supporting its renoprotective effects which may be mediated by attenuation of oxidative stress markers, downregulation of renal expressions of fibrotic (TGF-β), inflammatory (NF-κB) and kidney injury (Kim-1) markers along with upregulation of renal antiapoptotic marker (Bcl-2) gene expressions.

Abstract
Fluorosis is a major health problem affecting normal physiological and metabolic functions in people living in endemic fluoride areas. The present work was aimed at investigating the role of basal, high carbohydrate low protein (HCLP) and high protein low carbohydrate (HPLC) diets and Mangifera indica fruit powder as a food supplement in fluoride-induced metabolic toxicity. Exposure to fluoride resulted in elevation of plasma glucose levels, ACP, ALP, SGPT, SGOT, and hepatic G-6-Pase activities, plasma and hepatic lipid profiles with decreased plasma protein, HDL-C, hepatic glycogen content and hexokinase activity in basal, HCLP and HPLC diet fed albino rats. However among the three diets tested, HPLC diet was found to be relatively, a better metabolic regulator. All the three formulated diets (basal, HCLP and HPLC) supplemented with mango fruit powder (5 and 10 g), decreased plasma glucose content, ACP, ALP, SGPT, SGOT and hepatic G-6-Pase activities and plasma as well as hepatic lipid profiles. These diets also elevated the hepatic glycogen content and hexokinase activities. These effects however, were prominent with the HPLC diet supplemented with mango fruit powder and, among the two doses of mango fruit powder, the higher dose (10 g) yielded more promising results. It is surmised that the micronutrients and phytochemicals present in the diets and the mango fruit could be responsible for attenuation of fluoride-induced metabolic toxicity.

Abstract
Fluorosis is a major health problem in many parts of the world. The present work focuses on investigating the utility of nutrient and antioxidant rich grains- ragi, jowar, bajra, maize in formulation of basal, high carbohydrate low protein and low carbohydrate high protein diets in mitigating fluoride toxicity. Exposure to fluoride through drinking water not only significantly increased plasma glucose and lipid profiles, but also elevated both hepatic and renal lipid peroxidation, hepatic lipid profiles and G-6-Pase activity with a reduction in plasma HDL-C, hepatic glycogen content, hexokinase activity and antioxidant status. Even though basal and high carbohydrate diets did not significantly alter plasma glucose, lipid profiles in fluoride administered animals, protein enriched multigrain diet significantly decreased plasma glucose and lipid levels. However, the multigrain basal and high carbohydrate diets influenced the hepatic glycogen, lipid profiles, hexokinase and G-6-Pase activities, hepatic and renal lipid peroxidation and antioxidant status though not as significantly as that of multigrain diet enriched with protein. Thus the results of the present study indicate that both a multigrain diet rich in nutrients and antioxidants, and fortified with protein is useful in mitigating the fluoride toxicity.

Abstract
It has been reported that the herb, Phyllanthus niruri, possess antioxidant, anti-infection, anti-asthmatic, anti-diuretic, anti-soresis and many more beneficial activities. The goal of our present study was to evaluate the protective role of a 35 kD protein (PNP) isolated from this herb against iron-induced cytotoxicity in murine hepatocytes. Exposure of hepatocytes to iron (FeSO4) caused elevation of reactive oxygen species (ROS) production, enhanced lipid peroxidation and protein carbonylation, depleted glutathione levels, decreased the antioxidant power (FRAP) of the cells and reduced cell viability. Iron mediated cytotoxicity disrupted mitochondrial membrane potential (Δψm) and thereby caused apoptosis mainly by the intrinsic pathway via the down-regulation of IκBα with a concomitant up-regulation of NF-kB as well as the phosphorylation of ERKs and p38 MAP kinases. In addition, iron-induced cytotoxicity disrupted the normal balance of Bcl-2 family proteins in hepatocytes. Incubation of hepatocytes with PNP, however, protected the cells from apoptosis by stabilizing the mitochondria and arresting the release of cytochrome c. It also suppressed caspase activation and cleavage of PARP. Moreover, this protein has strong free radical scavenging activity and thereby scavenged ROS extensively. Combining all, results suggest that simultaneous treatment with PNP might suppress the iron-induced cytotoxicity in hepatocytes.

Abstract
BACKGROUND Limonia fruit pulp is edible and used in a number of food preparations. This fruit is also used as a folk medicine to treat various ailments and reportedly possesses antihyperglycaemic and antihyperlipidaemic activities. The purpose of the present study was to examine the potential of Limonia acidissima L. (LA) fruit pulp in regulating the carbohydrate and lipid profiles in fluoride-exposed rats. RESULTS Exposure to fluoride (100 mg l⁻¹ NaF) resulted in significant increases in plasma and hepatic carbohydrate and lipid profiles. Administration of LA fruit powder (2.5, 5 and 10 g kg⁻¹) in the diet for 4 weeks resulted in significant decreases in plasma glucose and lipid profiles and hepatic glucose-6-phosphatase activity and significant increases in hepatic glycogen content and hexokinase activity and plasma high-density lipoprotein cholesterol. Phytochemical analysis of the LA fruit pulp revealed the presence of fibres, phytosterols, saponins, polyphenols, flavonoids and ascorbic acid. CONCLUSION Consumption of LA fruit pulp is beneficial in controlling hyperglycaemia and hyperlipidaemia in fluoride-induced toxicity. Since fibres, phytosterols, saponins, polyphenols, flavonoids and total ascorbic acid are known to influence both carbohydrate and lipid metabolisms, the decline in carbohydrate and lipid levels in LA-administered fluoride-exposed rats could be attributed to the phytoconstituents of the fruit.

Abstract
In previous studies, we investigated a link between high fluoride exposure and functional IQ deficits in rats. This study is an extension conducted to explore the combined influence of physical exercise and temperature stress on the learning ability and memory in rats and to assess whether any positive modulation could be attenuated due to exercise regimen subjected to F-toxicated animals at different temperatures. Accumulation of ingested fluoride resulted significant inhibition in acetylcholinesterase activity (P < 0.05), plasma cortisol levels (P < 0.05), and impaired the acquisition, performance, latency time, and retention in fluoride-exposed animals. Fluoride-toxicated rats took more number of sessions during the learning phase [F (5, 35) = 19.065; P < 0.05] and post hoc analysis on the number of correct choices revealed that there was a significant effect of treatments [F (5, 30) = 15.763; P < 0.05]; sessions [F (8, 240) = 58.698; P < 0.05]; and also significant difference in the interactions [F (40, 240) = 1.583; P < 0.05]. The latency data also revealed a significant difference between groups [F (5, 30) = 28.085; P < 0.05]; time = [F (8, 240) = 136.314; P < 0.05]; and there was a significant difference in the interactions [F (40, 240) = 2.090; P < 0.05]. In order to ascertain if interdependence between fluoride concentrations and the foregoing free radical parameters, respective correlation coefficients were calculated and results clearly emphasize the positive role of exercise in the promotion of cognitive functions by decreasing fluoride levels in rat hippocampus. A significant recovery in cognitive function was noticed in all the exercised animals due to reduced burden of brain oxidative stress. In comparison to exercise regimens performed at different temperatures, high (35 °C) and low temperatures (20 °C) led to a slower acquisition and poor retention of the task when compared to thermo neutral temperatures (25 and 30 °C). Thus exercise up-regulate antioxidant defenses and promote learning abilities in fluorotic population.

Abstract
OBJECTIVES Fluoride is a serious health hazard across several nations, and chronic intake of fluoride deranges the carbohydrate, lipid and antioxidant metabolism in general. As there are limited remedial measures to prevent fluorosis, we investigated the role of tamarind leaf as a food supplement in restoration of carbohydrate, lipid and antioxidant metabolism in fluoride-exposed albino rats. METHODS Albino rats were exposed to fluoride (100 ppm sodium fluoride) through drinking water and fed diet supplemented with tamarind leaf powder (2.5, 5 and 10 g %) for 4 weeks. Carbohydrate, lipid and antioxidant profiles were investigated in both controls and fluoride-exposed animals. RESULTS While 4-week exposure to fluoride elevated plasma glucose and lipid profiles, simulating diabetic and hyperlipidaemic conditions, the antioxidant defence mechanisms of fluoride-exposed rats were compromised, with elevation and decline in lipid peroxidation and high-density lipoprotein (HDL)-cholesterol, respectively. When the diet was supplemented with tender tamarind leaves (used in southern India as a replacement for tamarind or other sour food ingredients), significant improvements in carbohydrate and lipid profiles occurred as evidenced by decreased plasma glucose and lipid levels, lipid peroxidation, increased hepatic glycogen content, hexokinase activity and cholesterol excretion, with simultaneous improvement in antioxidant profiles of both hepatic and renal tissues. CONCLUSIONS These findings are significant in view of the need for cost-effective approaches to tackle fluorosis as an environmental hazard and use of food supplements as ameliorative measures.

Abstract
CONTEXT Oxidative stress plays a key role in pathophysiology of many neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and so on. Although Matricaria recutita L. (Asteraceae), German chamomile, is traditionally used for central nervous system (CNS)-related diseases, its antistress properties have received little attention. OBJECTIVE The present study evaluated the neuroprotective effect of German chamomile against aluminium fluoride (AlF₄⁻)-induced oxidative stress in rats. MATERIALS AND METHODS The Sprague-Dawley rats of either sex (200-250 g) were selected and grouped as: group I received normal saline; group II received AlF₄⁻ (negative control); groups III, IV, and V received 100, 200, and 300 mg/kg, orally, German chamomile methanol extract (GCME) along with AlF₄⁻; and group VI received quercetin (25 mg/kg, i.p.) + AlF₄⁻, respectively. After 10 days treatment with GCME, oxidative stress was induced by administering AlF₄⁻ through drinking water for 7 days. Then, the protective antioxidant enzyme levels were measured and the histopathological studies were carried out. RESULTS The GCME showed dose-dependent neuroprotective activity by significant decrease in lipid peroxidation (LPO) and increase in the superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and total thiol levels in extract-treated animals as compared with negative control group (P < 0.001). The histopathological studies also revealed the potent neuroprotective action of German chamomile against oxidative brain damage. CONCLUSION The present study for the first time shows potent neuroprotective activity of the methanol extract of German chamomile against AlF₄⁻-induced oxidative stress in rats.

Abstract
Cadmium (Cd) is one of the ubiquitous environmental pollutants and is responsible for various organ pathophysiology including hepatic disorders. It is extremely toxic even in low concentrations and bioaccumulate in organisms. The present study has been carried out to investigate the cytoprotective role of arjunolic acid (AA), a tri terpenoid saponin, against Cd induced oxidative impairment and cell death in murine hepatocytes. Administration of cadmium (30 μM), in the form of chloride (CdCl(2)) for 2h, significantly enhanced the ALT, ALP and LDH leakage, increased reactive oxygen species (ROS) production, reduced hepatocytes viability and altered the antioxidant status of hepatocytes by reducing intracellular GSH level, anti-oxidant enzymes activity and increasing intracellular GSSG and lipid peroxidation. Evidence for Cd-induced nature of cell death was sought by flow cytometric analysis. Signal transduction studies revealed that Cd markedly increased the levels of caspase-9, -8, -3, Fas and Bid, decreased mitochondrial membrane potential, enhanced cytochrome c release in the cytosol, disturbed the Bcl-2 family protein balance, cleaved PARP protein and ultimately led to apoptotic cell death. Results showed that Cd could trigger both intrinsic and extrinsic apoptotic pathways. In addition, Cd markedly increased NF-κB nuclear translocation in association with IKKα/β phosphorylation and IκBα degradation. Simultaneous treatment with AA (200 μM), however, reduced Cd-induced oxidative stress, attenuated the nuclear translocation of NF-κB and protects the hepatocytes from Cd-induced apoptotic death. Combining, data suggest that Cd-induced hepatic dysfunction and apoptosis might be supported by the ROS formation and mediated via the activation of NF-κB. AA treatment, on the other hand, reduced Cd-induced oxidative stress, attenuated the activation of NF-κB and mitochondrion-dependent and independent apoptotic signaling pathways.

Abstract
The protective effect of an ethanol extract of Curcuma comosa against cisplatin-induced renal toxicity in mice was studied. Adult male mice were pretreated for 4 days with the ethanol extract of C. comosa [100-200 mg/kg body weight (BW), orally (p.o.)] before injection of cisplatin (12.5 mg/kg BW, intraperitoneally (i.p.)). Five days later the mice were killed, and blood samples were collected to determine blood urea nitrogen (BUN) and plasma creatinine levels. Kidneys were examined histopathologically and levels of lipid peroxidation, gluthathione (GSH) content, and superoxide dismutase (SOD), gluthathione peroxidase (GPx), and catalase (CAT) activities were determined. Histological examinations revealed degenerative changes and tubular necrosis in mice treated with cisplatin, which were improved by pretreatment with C. comosa ethanol extract. Cisplatin raised BUN, creatinine, and kidney lipid peroxidation levels, and lowered kidney GSH content and levels of GPx, SOD, and CAT activities, all of which (except SOD and CAT) could be restored to normal values by pretreatment with 200 mg/kg BW of C. comosa ethanol extract. In addition, the ethanol extract of C. comosa and its isolated diarylheptanoid compound also exhibited radical scavenging activities. The results suggest that the ethanol extract of C. comosa exhibits effective protection against cisplatin-induced nephrotoxicity mediated through its antioxidant activity.

Abstract
The present study was conducted to investigate the role of arjunolic acid (AA) against sodium fluoride (NaF)-induced cytotoxicity and necrotic cell death in murine hepatocytes. Dose-dependent studies suggest that incubation of hepatocytes with NaF (100mM) for 1h significantly decreased the cell viability as well as intracellular antioxidant power. Besides, NaF administration increased the activities of the membrane leakage enzymes and accumulation of intracellular reactive oxygen species; decreased the activities of the antioxidant enzymes, the glutathione (GSH) and total thiol contents; and elevated the level of oxidised glutathione (GSSG), lipid peroxidation end products as well as protein carbonyl content. In addition to the oxidative impairments, fluoride exposure caused hepatic cell death mainly via the necrotic pathway as supported by the flowcytometric and DNA fragmentation analyses. Incubation with AA (100 microg/ml) both prior to and in combination with NaF almost normalized the altered activities of antioxidant indexes. AA treatment enhanced the cellular antioxidant capability and protected hepatocytes against NaF-induced cytotoxicity and necrotic death. The cytoprotective activity of AA was found to be comparable to that of a known antioxidant, vitamin C. Combining, data suggest that AA plays a protective role against NaF-induced cellular damage and prevents hepatocytes from necrotic death.

Abstract
Arsenic is highly toxic naturally occurring element that affects numerous organ systems in humans. Present study was designed to investigate the preventive role of a triterpenoid saponin, arjunolic acid (AA) against arsenic-induced nephrotoxicity in mouse model. For this study, NaAsO(2) was chosen as the source of arsenic. Oral administration of NaAsO(2) at a dose of 10mg/kg body weight for 2 days caused significant accumulation of arsenic in renal tissues as well as altered the activities of serum markers, urea nitrogen (UN) and creatinine, antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), glutathione reductase (GR) and glutathione peroxidase (GPx), level of cellular metabolites, reduced glutathione (GSH), oxidized glutathione (GSSG) and total thiols, level of lipid peroxidation end products and protein carbonyl content. Treatment with AA at a dose of 20mg/kg body weight for 4 days almost normalized above indices. Histological studies also indicated preventive role of AA against NaAsO(2)-induced nephrotoxicity. The radical scavenging activity and in vivo antioxidant power of AA were determined from its DPPH radical scavenging ability and ferric reducing/antioxidant power (FRAP), respectively. A well-known antioxidant, vitamin C was used as positive control throughout the study. Combining all, results suggest that arsenic could cause kidney damage by inducing oxidative stress in mice and that could be prevented by AA.

Abstract
Arsenic-induced tissue damage is a major concern to the human population. An impaired antioxidant defense mechanism followed by oxidative stress is the major cause of arsenic-induced toxicity, which can lead to reproductive failure. The present study was carried out to investigate the preventive role of arjunolic acid, a triterpenoid saponin isolated from the bark of Terminalia arjuna, against arsenic-induced testicular damage in mice. Administration of arsenic (in the form of sodium arsenite, NaAsO(2), at a dose of 10 mg/kg body weight) for 2 days significantly decreased the intracellular antioxidant power, the activities of the antioxidant enzymes, as well as the levels of cellular metabolites. In addition, arsenic intoxication enhanced testicular arsenic content, lipid peroxidation, protein carbonylation and the level of glutathione disulfide (GSSG). Exposure to arsenic also caused significant degeneration of the seminiferous tubules with necrosis and defoliation of spermatocytes. Pretreatment with arjunolic acid at a dose of 20 mg/kg body weight for 4 days could prevent the arsenic-induced testicular oxidative stress and injury to the histological structures of the testes. Arjunolic acid had free radical scavenging activity in a cell-free system and antioxidant power in vivo. In summary, the results suggest that the chemopreventive role of arjunolic acid against arsenic-induced testicular toxicity may be due to its intrinsic antioxidant property.

Abstract
Arsenic is one of the ubiquitous environmental pollutants, which affects nearly all organ systems. The present study has been carried out to investigate the hepatoprotective role of arjunolic acid, a triterpenoid saponin, against arsenic-induced oxidative damages in murine livers. Administration of sodium arsenite at a dose of 10 mg/kg body weight for 2 days significantly reduced the activities of antioxidant enzymes, superoxide dismutase, catalase, glutathione S-transferase, glutathione reductase and glutathione peroxidase as well as depleted the level of reduced glutathione and total thiols. In addition, sodium arsenite also increased the activities of serum marker enzymes, alanine transaminase and alkaline phosphatase, enhanced DNA fragmentation, protein carbonyl content, lipid peroxidation end-products and the level of oxidized glutathione. Studies with arjunolic acid show that in vitro it possesses free radical-scavenging and in vivo antioxidant activities. Treatment with arjunolic acid at a dose of 20 mg/kg body weight for 4 days prior to arsenic administration prevents the alterations of the activities of all antioxidant indices and levels of the other parameters studied. Histological studies revealed less centrilobular necrosis in the liver treated with arjunolic acid prior to arsenic intoxication compared to the liver treated with the toxin alone. Effects of a known antioxidant, vitamin C, have been included in the study as a positive control. In conclusion, the results suggest that arjunolic acid possesses the ability to attenuate arsenic-induced oxidative stress in murine liver probably via its antioxidant activity.

Abstract
Arsenic is a well-established environmental toxin, which damages various organs of the body. A triterpenoid saponin, arjunolic acid (AA) has been isolated from the bark of Terminalia arjuna. The present study was conducted to investigate the preventive role of AA against arsenic-induced cytotoxicity in isolated murine hepatocytes. Sodium arsenite (NaAsO(2)) was chosen as the source of arsenic. Incubation of the hepatocytes with NaAsO(2) (1 mM) for 2 h caused reduction in the cell viability and activities of the intracellular enzymatic as well as non-enzymatic antioxidants. Treatment of NaAsO(2) enhanced lipid peroxidation and also increased the activities of the membrane leakage enzymes. Administration of AA (100 microg/ml) before and with the toxin almost normalized the altered activities of antioxidant indices. AA possesses free radical scavenging activity and could enhance the cellular anti-oxidant capability against NaAsO(2)-induced cyto-toxicity. The cytoprotective activity of AA was found to be comparable to that of a known antioxidant, vitamin C. Experimental results, therefore, suggest that AA protects arsenic-induced cytotoxicity in murine hepatocytes.

Abstract
Chronic and acute overproduction of reactive oxygen species (ROS) plays a positive role in the development of cardiovascular diseases under pathophysiological conditions. However, very little is known about carbon tetrachloride (CCl(4)) induced cardiac oxidative stress. The present study was conducted to find out CCl(4) induced oxidative insult in cardiac tissue and the cardioprotective effect of the 70% ethanol extractable active constituents of the bark of Terminalia arjuna (TA) against that stress in mice. Oral administration of CCl(4) at a dose of 1ml/kg body weight for 2 days significantly reduced the activities of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST), as well as depleted the level of reduced glutathione (GSH) in the cardiac tissue. In addition, extent of lipid peroxidation and the level of oxidized glutathione (GSSG) were increased under the same experimental conditions. Oral treatment of the active constituents of TA at a dose of 50mg/kg body weight for 7 days prior to CCl(4) administration significantly restored the activities of all antioxidant enzymes as well as increased the level of GSH and decreased the level of lipid peroxidation end products. In addition, FRAP assay showed that the active constituents of TA enhanced the cardiac intracellular antioxidant activity. Histological studies also supported the cardioprotective role of the active constituents. The active constituents-induced protective effect was compared with a known antioxidant, vitamin C. To the best of our knowledge, this is the first report describing the CCl(4) induced cardiac oxidative stress and cardioprotective action of the active phytoconstituents of Terminalia arjuna against that oxidative insult.
