Abstract
Lung pleomorphic carcinoma is a rare and aggressive cancer that uncommonly metastasizes to the colon and only a few case reports have been published thus far. We present an exceptional case of colon metastasis from lung pleomorphic carcinoma in a 68-year-old man which was revealed by large bowel perforation, and we review the previous three published cases. Metastasis to the bowel from primary lung malignancy often lacks specific symptoms which result in delayed diagnosis. Bowel metastasis is a poor prognostic factor in patients with lung pleomorphic carcinoma, regardless of management strategy.

Abstract
BACKGROUND Breast cancer is the first female cancer worldwide. Its prognosis depends mainly on pathological stage and histological grade. These classical prognostic factors are essential but may be insufficient to predict the outcome of the disease. Research focuses on identifying new prognostic factors such as CD10, which is a cell surface metalloproteinase. OBJECTIVE This study aims to evaluate CD10 expression on stromal and tumor cells in invasive breast carcinomas and its correlations with other clinicopathological factors and survival. METHODS A series of 100 cases of breast carcinoma of no special type diagnosed from 2009 to 2011, was investigated in this study. CD10 expression was detected by immunohistochemistry. Stromal CD10 expression (=10% stromal positivity was considered positive) and tumor cells expression (=1% stained carcinomatous cells) were noted. Statistical correlations were analyzed with different known prognostic parameters; survival analysis were performed using SPSS 22.0. RESULTS Stromal CD10 expression was seen in 60% of the cases. It showed positive correlation with high tumor grade (p=0,012) and distant metastasis (p=0,02). CD10 expression on tumor cells was observed in 10% of the cases. It was associated with high tumor grade (p=0,009), hormone receptor negativity (estrogen receptor: p<0,0001), progesterone receptor: p=0,005), triplenegative phenotype (p=0,001), and Ki67 overexpression (p=0,046). Stromal CD10 expression was significantly associated to a shorter overall survival (p=0,029) and disease-free survival (p=0,05) in univariate analysis. CONCLUSION Given these results, it can be concluded that CD10 expression predict an aggressive behavior of breast cancer. This marker can be introduced as a determinant prognostic factor.

Abstract
This work was intended to prepare biodegradable and edible films from polysaccharide extracted from Hammada scoparia leaves (named PSP) and reinforced by poly (vinyl alcohol) (PVA). Four films with different ratios of PSP/PVA: P1 (70:30), P2 (50:50), FP3 (30:70) and pure PVA (100 % PVA) were prepared and characterized in terms of structural (FT-IR), physical (Thickness, solubility and swelling index), optical and thermal properties (TGA). The antioxidant activities of different films were determined in vitro and evaluated in vivo through the examination of wound healing capability. Data revealed that the film P1 displayed the highest antioxidant activity in vitro and accelerated significantly the wound healing, after sixteen days of treatment, attested by higher wound appearance scores and a higher content of collagen (765.924 ± 4.44 mg/g of tissue) confirmed by histological examination, when compared with control, CYTOL CENTELLA® and pure PVA-treated groups. Overall, these results demonstrated that PSP/PVA based films exhibited a higher wound healing potential confirmed with the high antioxidant activities in vitro.

Abstract
Leydig cell tumor (LCT) is a rare testicular tumor with a low incidence accounting 3% of all testicule neoplasms. Due to its rarity, the natural history of LCT is poorly understood. Patients can present with atypical symptoms and endocrine disorders. The diagnosis of LCT is based on histological and immunohistochemical examination. We report a new case of leydig cell tumor in a 61-year-old man presenting with a left testis hydrocele. The patient underwent a left orchidectomy and the diagnosis of LCT was established. Even in front of a benign pathology such as hydrocele, exploration is necessary to detect any testicle tumor.

Abstract
OBJECTIVE This research was performed to evaluate the effect of tebuconazole (TBZ) on reproductive organs of male rats and to assess the protective role of combined essential trace elements in alleviating the detrimental effect of TBZ on male reproductive function. METHODS For this purpose, 48 rats were exposed to 100 mg/kg TBZ, TBZ supplemented with zinc (Zn), selenium (Se), copper (Cu), and iron (Fe), TBZ + (Se + Zn); TBZ + Cu; or TBZ + Fe. The experiment was conducted for 30 consecutive days. RESULTS TBZ caused a significant perturbation in mineral levels and reduction in reproductive organs weights, plasma testosterone level, and testicular antioxidant enzyme activities. The TBZ-treated group also showed a significant increase in sperm abnormalities (count, motility, and viability percent), plasma follicle-stimulating hormone and luteinizing hormone concentrations, lipid peroxidation, protein oxidation, and severe DNA degradation in comparison with the controls. Histopathologically, TBZ caused testis impairments. Conversely, treatment with trace elements, in combination or alone, improved the reproductive organ weights, sperm characteristics, TBZ-induced toxicity, and histopathological modifications in testis. CONCLUSION TBZ exerts significant harmful effects on male reproductive system. The concurrent administration of trace elements reduces testis dysfunction, fertility, and toxicity induced by TBZ.

Abstract
The identification of the mutations that drive lung cancer have furnished new targets for the treatment of non-small cell lung cancer (NSCLC) and led to the development of targeted therapies such as tyrosine kinase inhibitors that are used to combat the molecular changes promoting cancer progression. Furthermore, biomarkers identified from gene analysis can be used to detect early lung cancer, determine patient prognosis, and monitor response to therapy. In the present study we analyzed the molecular profile of seventy-three Tunisian patients with lung adenocarcinoma (LAD). Mutational analyses for EGFR and KRAS were performed using direct sequencing, immunohistochemistry or MassARRAY. Anaplastic lymphoma kinase (ALK) rearrangement was evaluated by immunohistochemistry using the D5F3 clone, and p53 expression was also assessed. The median age of patients at diagnosis was 61 years (range 23-82 years). Using different methodologies, EGFR mutations were found in 5.47% of patients and only exon 19 deletions "E746-A750 del" were detected. KRAS mutations were present in 9.58% of cases, while only one patient was ALK-positive. Moreover, abnormal immunostaining of p53 was detected in 56.16% of patients. In conclusion, the detected rates of EGFR and KRAS mutation and ALK rearrangement were lower than those found in European and Asian countries, whereas, abnormal p53 expression was slightly more frequent. Furthermore, given the small sample size of this study, a more comprehensive analysis of this patient set is warranted.

Abstract
The risk of pesticides on the human health and environment has drawn increasing attention. Today, new tools are developed to reduce pesticide adverse effects. This study aimed to evaluate the toxicity induced by, thiamethoxam (TMX), and the cytoprotective effect of a novel polysaccharide, named fenugreek seed water polysaccharide (FWEP) in vitro using H9c2 cardiomyoblastes and in vivo using Wistar rat model. Animals were assigned into four groups per eight rats each: group 1 served as a control group, group 2 received TMX, group 3, and group 4 received both FWEP and TMX tested at two doses (100 and 200 mg/kg, respectively). Regarding the in vitro study, our results demonstrated that TMX induced a decrease in H9c2 cell viability up to 70% with the highest concentration. In vivo, TMX injection induced marked heart damage noted by a significant increase in plasma lactate dehydrogenase, creatine phosphokinase, troponin-T, aspartate amino transferase activities, cholesterol, and triglyceride levels. Concomitant alterations in cardiac antioxidant defense system revealed depletion in the levels of glutathione and non-protein thiol and an increase in the activity of superoxide dismutase, catalase, and glutathione peroxidase. Similarly, a significant increase in heart lipid, malondialdehyde, advanced oxidation protein product and in protein carbonyls levels was also noted. In addition, heart tissues histo-architecture displayed major presence of apoptosis and necrosis as confirmed by DNA degradation. However, supplementation with FWEP alleviated heart oxidative damage and genotoxicity. In this manner, ABTS radical-scavenging activity, linoleic acid oxidation tests and heart genomic and DNA nicking assay had proved FWEP strong antioxidant potential. In conclusion, FWEP provided significant protection against TMX-induced heart injury, and could be a useful and efficient agent against cardiotoxicity and atherosclerosis.

Abstract
CONTEXT Hypercholesterolemia has significant cardiac consequences, since it is among the major risk factors of ischemic heart diseases. OBJECTIVE The aim was searching the cardioprotective effect of chemical constituents from the sea lettuce Ulva lactuca upon hypercholesterolemic regime in mice. MATERIAL AND METHODS Mice were randomly divided into three groups: untreated group, hypercholesterolemic group, and mice receiving 1% cholesterol associated with U. lactuca ethanolic extract. RESULTS In vitro study demonstrated that algal extract has antioxidant efficacy attributable to the presence of phenolic compounds. Additionally, the alga alleviated cardiotoxicity, as shown by the improvement of haematological parameters, white cell viability, heart oxidative stress, plasma biochemical parameters and index of atherogenesis. Gene expression of the proinflammatory cytokines TNF-α, IL-1β and IL-6 significantly decreased in the heart of U. lactuca supplemented hypercholesterolemic animals. CONCLUSION It was established that the green alga, thanks to its bioactive compounds, effectively counteracts cardiotoxic effects of hypercholesterolemic regime.

Abstract
The current study aimed at evaluating the ability of a mineral and antioxidant-rich extract from Chondrus canaliculatus to improve maneb (MB)-induced toxicity in adult rat. The animals were divided into four groups: group 1 used as a control group, group 2 received MB, group 3 received MB + C. canaliculatus extract, and group 4 received only the algal extract. MB, a Mn-containing ethylene-bis-dithiocarbamate fungicide, induced oxidative stress damages, mineral perturbations in the plasma, urine, and bone, and genotoxicity in rats. Hematological analysis revealed in the MB-treated group a disruption in the number of red blood cells, platelets, and white blood cells associated with a striking genotoxicity. Interestingly, a significant increase in malondialdehyde and advanced oxidation protein product levels in erythrocytes and bones were found. On the other hand, an impairment of the antioxidant status in both tissues was occurred. Along, our results revealed that MB injection caused a striking drop and disruption in bone's mineral rates, especially calcium and phosphorus. These biochemical results were in accordance with the histological and molecular changes. However, co-treatment with C. canaliculatus extract showed, for the first time, that this alga was effective against MB-induced hematotoxicity, genotoxicity, and oxidative stress in the blood and bone and maintained osteomineral metabolism and bone histo-architecture. Such observations might be explained by the strong in vitro antioxidant and antibacterial activities exhibited by the alga, as well as by its high levels in several minerals: calcium, phosphorus, sodium, potassium, magnesium, iron, and zinc.

Abstract
OBJECTIVE The current study aimed to elucidate the effect of vanillin on behavioral changes, oxidative stress, and histopathological changes induced by potassium bromate (KBrO3), an environmental pollutant, in the cerebellum of adult mice. METHODS The animals were divided into four groups: group 1 served as a control, group 2 received KBrO3, group 3 received KBrO3 and vanillin, and group 4 received only vanillin. We then measured behavioral changes, oxidative stress, and molecular and histological changes in the cerebellum. RESULTS We observed significant behavioral changes in KBrO3-exposed mice. When investigating redox homeostasis in the cerebellum, we found that mice treated with KBrO3 had increased lipid peroxidation and protein oxidation in the cerebellum. These effects were accompanied by decreased Na+-K+ and Mg2+ ATPase activity and antioxidant enzyme gene expression when compared to the control group. Additionally, there was a significant increase in cytokine gene expression in KBrO3-treated mice. Microscopy revealed that KBrO3 intoxication resulted in numerous degenerative changes in the cerebellum that were substantially ameliorated by vanillin supplementation. Co-administration of vanillin blocked the biochemical and molecular anomalies induced by KBrO3. CONCLUSION Our results demonstrate that vanillin is a potential therapeutic agent for oxidative stress associated with neurodegenerative diseases.

Abstract
CONTEXT Polysaccharides (PSs) from seaweeds have been reported to possess biological activity of potential medicinal values. OBJECTIVE The current study was conducted to establish the protective effects of PS extracted from Ulva lactuca against oxidative stress induced by Thiacloprid (THC) in the rat reproductive system. MATERIALS AND METHODS Rats were exposed either to THC, THC + PS (100 mg/kg), or THC + PS (200 mg/kg). RESULTS Our study showed that THC induced severe disorders in the functional sperm parameters. A decrease in antioxidant activities and their genes expression were observed in the same group, compared to the controls. Our molecular data showing also a severe DNA breakdown in the testis of THC treated group. Moreover, THC treated group showed severe histopathological changes. CONCLUSIONS Our results revealed that PS extracted from Ulva lactuca alleviated the THC induced reprotoxicity and reduced oxidative stress damages, DNA breakdown and histological injuries in the testis.

Abstract
The present study investigates the toxic effects of acrylamide (ACR) administered to rats at two doses on (i) oxidative stress and disruption of pro-oxidant/antioxidant balance in hepatic cells and (ii) its correlation with metallothioneins (MTs) genes expression, DNA damage and histomorphological changes. Treated rats with 20 and 40 mg/kg body weight of ACR led to an increase in malondialdehyde, hydrogen peroxide, advanced oxidation protein products, protein carbonyl levels as well as an alteration in the antioxidant status. Total MT content in the liver and MT I and MT II genes induction were increased. Plasma transaminases activities, albumin, total protein and glucose levels were also increased, while alkaline phosphatase activity was decreased. Moreover, total cholesterol (TC), triglyceride, low-density lipoprotein cholesterol (LDL-C) levels, TC/high-density lipoprotein cholesterol (HDL-C) and LDL-C/HDL-C ratios were increased, while HDL-C decreased in a dose-dependent manner. A random DNA degradation was observed only in the liver of ACR-treated rats with the highest dose. These changes were confirmed by histopathological observations.

Abstract
The aim of this study was to elucidate the redox effects of Thiophanate methyl (MT) in the rat liver and kidney. Our results showed, after 3 days of MT injection (700 mg/kg), an increase in malondialdehyde (MDA), hydrogen peroxide and advanced oxidation protein products levels. Glutathione peroxidase and superoxide dismutase activities were also remarkably increased in the liver but decrease in the kidney. Glutathione and vitamin C values were significantly reduced. The changes in biochemical parameters were substantiated by histological and molecular data. A smear without ladder formation on agarose gel was shown, indicating random DNA degradation in the liver and the kidney of MT treated rats. The increase in cyclooxygenase-2 gene expression, marker of inflammation, and an increase in genes expression of glutathione peroxidase and superoxide dismutase in liver and their decrease in the kidney were also occurred after MT exposure. These data confirmed the pro-oxidant and genotoxic effects of this fungicide.

Abstract
Chronic exposure to potassium bromate (KBrO3 ), a toxic halogen existing widely in the environment, environment through contaminated drinking water, has become a global problem of public health. The present study investigates the protective role of vanillin against KBrO3 induced oxidative stress, distruption in inflammatory cytokines expression, DNA damage, and histopathological changes. Adult mice were exposed orally to KBrO3 (2g/L of drinking water) for 2 weeks The co-administration of vanillin to the KBrO3 -treated mice significantly prevented the plasma transaminases increase in. Furthermore, it inhibited hepatic lipid peroxidation (malondialdehyde), advanced oxidation protein product (AOPP) and protein carbonyl (PCO) formation and attenuated the KBrO3 -mediated depletion of enzymatic and non enzymatic antioxidants catalase, superoxide dismutase, and glutathione peroxidase activities and glutathione level in the liver. In addition, vanillin markedly attenuated the expression levels of proinflammatory cytokines, including tumor necrosis factor-α, interleukin-1β, interleukin-6, and COX2 and prevented KBrO3 -induced hepatic cell alteration and necrosis, as indicated by histopathological data. DNA damage, as assessed by the alkaline comet assay, was also found to be low in the co-treated group. Thus, these findings show that vanillin acts as potent chemopreventive agent against KBrO3 -mediated liver oxidative stress and genotoxicity through its antioxidant properties. © 2015 Wiley Periodicals, Inc.

Abstract
Accumulation of aluminium and acrylamide in food is a major source of human exposure. Their adverse effects are well documented, but there is no information about the health problems arising from their combined exposure. The aim of the present study was to examine the possible neurotoxic effects after co-exposure of pregnant and lactating rats to aluminium and acrylamide in order to evaluate redox state, cholinergic function and membrane-bound ATPases in the cerebellum of adult rats and their progeny. Pregnant female rats have received aluminium (50 mg/kg body weight) via drinking water and acrylamide (20 mg/kg body weight) by gavage, either individually or in combination from the 14th day of pregnancy until day 14 after delivery. Exposure to these toxicants provoked an increase in malondialdehyde (MDA) and advanced oxidation protein product (AOPP) levels and a decrease in SOD, CAT, GPx, Na+K+-ATPase, Mg2+-ATPase and AChE activities in the cerebellum of mothers and their suckling pups. A reduction in GSH, NPSH and vitamin C levels was also observed. These changes were confirmed by histological results. Interestingly, co-exposure to these toxicants exhibited synergism based on physical and biochemical variables in the cerebellum of mothers and their progeny.

Abstract
Hepatotoxicity, induced by aluminium chloride (AlCl3), has been well studied but there are no reports about liver metallothionein (MT) genes induction. Therefore, it is of interest to establish the mechanism involving the relation between MT gene expression levels and the oxidative stress status in hepatic cells of aluminium-treated rats. Aluminium (Al) was administered to rats in their drinking water at a dose of 50 mg/kg body weight for three weeks. AlCl3 provoked hepatotoxicity objectified by an increase in malondialdehyde (MDA), hydrogen peroxide (H2O2), advanced oxidation protein products (AOPP), protein carbonyls (PCO) and a decrease in reduced glutathione (GSH), non-protein thiols (NPSH) and vitamin C. CAT and Glutathione peroxidase (GPx) activities were decreased while Mn-SOD gene expression, total Metallothionein content and MT I and MT II genes induction were increased. There are changes in plasma of some trace elements, albumin levels, transaminases, LDH and ALP activities. All these changes were supported by histopathological observations.

Abstract
Aluminum chloride (AlCl3) and acrylamide (ACR) are well known as environmental pollutants inducing oxidative stress. Our study investigated the effects of these contaminants and if the hydrophilic fraction of extra virgin olive oil was able to prevent lung oxidative stress and DNA damage. Animals were divided into four groups of six each: group 1, serving as controls, received distilled water; group 2 received in drinking water aluminum chloride (50 mg/ kg body weight) and by gavage acrylamide (20 mg/kg body weight); group 3 received both aluminum and acrylamide in the same way and the same dose as group 2 and hydrophilic fraction from olive oil (OOHF) (1 ml) by gavage; group 4 received only OOHF by gavage. Exposure of rats to both aluminum and acrylamide provoked oxidative stress in lung tissue based on biochemical parameters and histopathological alterations. In fact, we have observed an increase in malondialdehyde (MDA), H2O2, and advanced oxidation protein product (AOPP) and a decrease in reduced glutathione (GSH), non-protein thiols (NPSH), and vitamin C levels. Activities of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD) were also decreased. Histopathological changes in lung tissue were noted like emphysema, vascular congestion, and infiltration of inflammatory cells. A random DNA degradation was observed on agarose gel in the lung of AlCl3 and acrylamide (ACR)-treated rats. Co-administration of OOHF to treated rats improved biochemical parameters to near control values and lung histoarchitecture. The smear formation of genomic DNA was reduced. The hydrophilic fraction of extra virgin olive oil might provide a basis for developing a new dietary supplementation strategy in order to prevent lung tissue damage.

Abstract
CONTEXT Pomegranate (Punica granatum L., Punicaceae) is known to possess enormous antioxidant activity. OBJECTIVE This study investigates the protective effects of pomegranate peel against barium-mediated renal damage. MATERIALS AND METHODS Rats were exposed during 21 days either to barium (67 ppm), barium + pomegranate peel (5% of diet) or to only pomegranate peel (5% of diet). RESULTS Exposure rats to barium provoked a significant increase in kidney malondialdehyde (MDA), advanced oxidation protein products (AOPP) and hydrogen peroxide (H2O2) levels. Creatinine, urea and uric acid levels in plasma and urine were also modified. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) activities, non protein thiol (NPSH) and reduced glutathione (GSH) levels were decreased. Metallothionein (MT) production was increased and their genes expressions were up-regulated. All these changes were improved by dietary pomegranate peel. Moreover, the distorted histoarchitecture in kidney of barium group was alleviated by pomegranate peel. CONCLUSION Our data showed, for the first time, the protective effects of pomegranate peel against barium-induced renal oxidative damage.

Abstract
The present study was performed to establish the therapeutic efficacy of pomegranate peel against barium chloride induced liver injury. Adult rats were divided into four groups of six animals each: group I, serving as controls, received distilled water; group II received by their drinking water 67 ppm of BaCl2; group III received both 67 ppm of BaCl2 by the same way than group II and 5 % of pomegranate peel (PP) via diet; group IV received 5 % of PP. Analysis by HPLC/MS of PP showed its rich composition in flavonoids such as gallic acid, castalin, hyperin, quercitrin, syringic acid, and quercetin. The protective effects of pomegranate peel against hepatotoxicity induced by barium chloride were assessed using biochemical parameters and histological studies. Exposure of rats to barium caused oxidative stress in the liver as evidenced by an increase in malondialdehyde (MDA), lipid hydroperoxides (LOOHs), H2O2 and advanced oxidation protein product (AOPP) levels, and lactate dehydrogenase (LDH), gamma glutamyl transpeptidase (GGT), alanine aminotransferase (AST) and aspartate aminotransferase (ALT) activities, a decrease in catalase (CAT) and glutathione peroxidase (GPx) activities, glutathion (GSH), non-protein thiol (NPSH), vitamin C levels, and Mn-SOD gene expression. Liver total MT levels, MT-1, and MT-2 and pro-inflammatory cytokine genes expression like TNF-α, IL-1β and IL-6 were increased. Pomegranate peel, supplemented in the diet of barium-treated rats, showed an improvement of all the parameters indicated above.The present work provided ethnopharmacological relevance of pomegranate peel against the toxic effects of barium, suggesting its beneficial role as a potential antioxidant.

Abstract
Oxidative stress generated by an excessive production of free radicals has been linked to the development of several health problems such as cardiovascular diseases. We investigated the protective efficacy of Extra Virgin Olive Oil (EVOO) and its lipophilic fraction (OOLF) and hydrophilic fraction (OOHF) against the cardiotoxicity and DNA damage induced by co-exposure to aluminum (AlCl3) and acrylamide (ACR). Rats were divided into eight groups of six each: controls, AlCl3 (50 mg per kg body weight) administered via drinking water and ACR (20 mg per kg body weight) given by gavage, combined group plus EVOO (300 μl); combined group plus the hydrophilic fraction (1 ml); combined group plus the lipophilic fraction (300 μl); extra virgin olive oil (EVOO) and its fractions were administered daily by gavage for 21 days. Three other groups, considered as positive controls, received either EVOO, OOLF or OOLH. Exposure of rats to both AlCl3 and ACR provoked oxidative stress objectified by an increase in MDA, AOPP and a decrease in GSH, NPSH and vitamin C levels. The activities of CAT, GPx and SOD were also decreased. EVOO and its OOLF fraction exhibited a pronounced enhancement of antioxidant status while a partial recovery in the antioxidant status was obtained with the OOHF fraction. Plasma LDH and CK activities, TC, LDL-C levels, TC/HDL-C and LDL-C/HDL-C ratios were increased, while HDL-C and TG decreased in rats treated with both AlCl3 and ACR. Co-administration of EVOO, OOLF or OOHF to treated rats restored cardiac biomarkers and lipid profile to near-normal values. Histological studies and DNA damage confirmed the biochemical parameters and the beneficial role of EVOO and its two fractions. Our results suggest that extra virgin olive oil and its two fractions can decrease the frequency of cardiac complications and genotoxicity.

Abstract
The present study was performed to evaluate the protective effect of selenium (Se) against penconazole (PEN)-induced oxidative stress in the cardiac tissue of adult rats. Male Wistar rats were divided into four groups of six each. The first group represented the controls. For the second group (PEN), no treatment was performed during the first 6 days, and then, the rats received intraperitoneally 67 mg/kg body weight (bw) of PEN every 2 days from day 7 until day 15, the sacrifice day. For the third group (Se + PEN), Se was administered daily through the diet at a dose of 0.5 mg/kg of diet for 15 days. Rats of this group received also every 2 days PEN (67 mg/kg bw) from day 7 until day 15. The fourth group (Se) received daily, through the diet, Se (0.5 mg/Kg of diet) during 15 days. Our results showed that Se reduced significantly the elevated cardiac levels of malondialdehyde and protein carbonyl following PEN treatment, and attenuated DNA fragmentation induced by this fungicide. In addition, Se modulated the alterations of antioxidant status: enzymatic (superoxide dismutase, glutathione peroxidase, and catalase) and nonenzymatic (glutathione and vitamin C) antioxidants in the heart of PEN-treated rats. This trace element was also able to alleviate perturbations of lipid profile. The protective effect of selenium was further evident through the histopathological changes produced by PEN in the heart tissue. Taken together, our results indicated that Se might be beneficial against PEN-induced cardiac oxidative damage in rats.

Abstract
In the course of searching for hepatoprotective agents from natural sources, the protective effect of chemical constituents of the marine red alga Alsidium corallinum (A. corallinum) against potassium bromate (KBrO3)-induced liver damage in adult mice was investigated. The in vitro antioxidant and antibacterial properties of A. corallinum were firstly investigated. Then, A. corallinum was tested in vivo for its potential protective effects against damage caused by KBrO3 in mice models divided into four groups: controls, KBrO3, KBrO3 + A. corallinum, and A. corallinum. Our results demonstrated the rich composition of A. corallinum in antioxidant compounds like phenolics, flavonoids, anthocyanins, polysaccharides, chlorophyll and carotenoids. Its antioxidant activity was also confirmed using β-carotene bleaching by linoleic acid assay, reducing sugar test and trolox equivalent antioxidant capacity. The ethanolic extract of A. corallinum also showed good inhibition of the tested bacteria. The coadministration of the red alga associated to the KBrO3 alleviated hepatotoxicity as monitored by the improvement of hepatic oxidative stress biomarkers and plasma biochemical parameters, when compared to the KBrO3-treated mice. These results were confirmed by the improvement of histological and molecular changes. Treatment with A. corallinum prevented liver damage induced by KBrO3, thus protecting the body against free radicals and reducing inflammation and hypercholesterolemia risks.
