Abstract
Mercury chloride is a type of heavy metal that causes the formation of free radicals, causing hepatotoxicity, nephrotoxicity and apoptosis. In this study, the effects of naringenin on oxidative stress and apoptosis in the liver and kidney of rats exposed to mercury chloride were investigated. In the study, 41 2-month-old male Wistar-Albino rats were divided into five groups. Accordingly, group 1 was set as control group, group 2 as naringenin-100, group 3 as mercury chloride, group 4 as mercury chloride + naringenin-50, and group 5 as mercury chloride + naringenin-100. For the interventions, 1 mL/kg saline was administered to the control, 0.4 mg/kg/day mercury (II) chloride to the mercury chloride groups by i.p., and 50 and 100 mg/kg/day naringenin prepared in corn oil to the naringenin groups by gavage. All the interventions lasted for 20 days. Mercury chloride administration was initiated 1 h following the administration of naringenin. When mercury chloride and the control group were compared, a significant increase in plasma urea, liver and kidney malondialdehyde (MDA) levels, in kidney superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), glutathione-S-transferase (GST) activities (p < .001), and a significant decrease in liver and kidney glutathione (GSH) levels (p < .001), in liver catalase (CAT) activity (p < .01) were observed. In addition, histopathological changes and a significant increase in caspase-3 levels were detected (p < .05). When mercury chloride and treatment groups were compared, the administration of naringenin caused a decrease aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) (p < .01), urea, creatinine levels (p < .001) in plasma, MDA levels in liver and kidney, SOD, GSH-Px, GST activities in kidney (p < .001), and increased GSH levels in liver and kidney. The addition of naringenin-100 increased GSH levels above the control (p < .001). The administration of naringenin was also decreased histopathological changes and caspase-3 levels (p < .05). Accordingly, it was determined that naringenin is protective and therapeutic against mercury chloride-induced oxidative damage and apoptosis in the liver and kidney, and 100 mg/kg naringenin is more effective in preventing histopathological changes and apoptosis.

Pediatr Blood Cancer 2022; 69:e29496. [PMID: 34842343 DOI: 10.1002/pbc.29496] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Revised: 11/07/2021] [Accepted: 11/08/2021] [Indexed: 02/05/2023]
Abstract
OBJECTIVES Omega 3 polyunsaturated fatty acids are dietary factors with several beneficial cardiovascular effects. This study aimed to assess the possible protective effect of omega 3 fatty acids on early doxorubicin-induced cardiac toxicity in children with acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS Sixty children of newly diagnosed ALL were randomized into two groups: group I (n = 30) who received omega 3 fatty acids 1000 mg/day for 6 months in addition to their usual protocol of chemotherapy including doxorubicin; and group II (n = 30) who received their usual doxorubicin protocol during the period from February 2020 till August 2021. Echocardiographic examinations were performed before and after the treatment. Glutathione, malondialdehyde (MDA), superoxide dismutase (SOD), troponin I, creatine kinase MB (CK-MB), and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured also before and after omega 3 treatment. RESULTS After 6 months of omega 3 administration, group I had a significantly lower MDA level and a significantly higher glutathione and SOD levels than group II. Similarly, the levels of troponin I, CK-MB, and NT-proBNP were significantly high in group II, whereas they were unchanged in group I after treatment. Similarly, systolic function (presented with peak mitral annular systolic velocity and two-dimensional global longitudinal strain) of the heart was preserved in omega 3-treated patients, unlike the control group that showed significant impairment of left ventricular function after 6 months. CONCLUSION Omega 3 fatty acids may decrease early cardiac injury and doxorubicin-induced cardiotoxicity in children with ALL.

Abstract
Synthetic pyrethroid pesticide is commonly used in agricultural activities in the Black Sea region during reproduction period of turbot. In this sense, in vivo and in vitro studies have shown that cypermethrin (CYP) could be one of the environmental factors affecting decreasing turbot stocks. In this study, effects of in vivo and in vitro administration of CYP, a synthetic pyrethroid, on sperm kinematics motility (MOT), progressive motility (PM), curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity (LIN), straight line velocity (STR), amplitude of lateral head (ALH), beat cross frequency (BCF), oxidative stress biomarkers malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and lipid peroxidation (LPO) and also histopathological alterations in gonads were investigated in spermatazoa of turbot (Schopthalmus maximus). Broodstock was supplied from culture origin and used in spawning season, additionally, two (0, 0.187 and 0.218 ppb) and three (0, 1.025, 2.05 and 4.1 ppb) different CYP concentrations were performed for in vivo and in vitro studies, respectively. In vivo and in vitro studies, significant reductions were found in sperm MOT, PM, VCL, VSL, VAP, LIN, and ALH properties depend on the increase in CYP concentrations (p < 0.05). Besides, activities of GSH, GPx, SOD, and CAT increased. In terms of histological alterations, no difference was observed among groups (0, 0.187 and 0.218 ppb) in the maturity stage of the germ cells. According to obtained results, sperm kinematics was affected significantly with increased the dose levels of CYP (p < 0.05).

Abstract
INTRODUCTION The aim of this study was to determine the genetic polymorphisms of some antioxidant enzymes together with oxidative stress and the response of some antioxidant enzymes against this situation in vascular and endovascular interventions performed for diseases of the infrarenal abdominal aorta. MATERIAL AND METHODS Twenty-four current or ex-smoker patients (eight aortoiliac occlusive disease (AOD), 16 abdominal aortic aneurysm (AAA)) who were operated were included in this pilot study. Malonyl dialdehyde (MDA) levels, as an indicator of oxidative stress, reduced glutathione, catalase and superoxide dismutase enzymes, which are indicators of antioxidant status, which were measured in aortofemoral bypass in AODs, and in endovascular abdominal aortic aneurysms repairs in the preoperative, operative, and postoperative periods. Genetic polymorphisms of these antioxidant enzymes developing a response to the damage in the preoperative blood samples were determined by using the PCR-RFLP method. RESULTS The lack of a significant increase of MDA (nmol/ml preoperative: 2.57 ±0.19, operative: 2.59 ±0.21, postoperative: 2.64 ±0.22, p = 0.63) in the oxidative damage in the operative and postoperative periods compared to the preoperative period prevented the damage and was thought to be associated with the elevation of some effective antioxidant parameters in the operative and postoperative periods. CONCLUSIONS It may be thought that both types of interventions are quite reliable in terms of oxidative damage and, accordingly, the effect of the procedure-associated oxidative damage in the postoperative complications is low or ineffective. Two genotypes were obtained in each of the three gene areas of the patients, and no statistical significance was determined between the genotypes (p > 0.05).

Abstract
Metabolic alterations and inflammation are regarded as hallmarks of cancer. Glycolytic flux and intermediate accumulation lead to the production of building blocks and NADPH which is important in protecting the cell from oxidative damage. Inflammation causes the release of mediators responsible for regulating molecular mechanism affecting metabolic pathways. CaFB due to its cis-diol-rich feature may have the potential to interact with molecules taking part in cancer development. This study was aimed to investigate the effects of CaFB on metabolic alterations and inflammation in 7,12-dimethylbenz(a)anthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA)-induced skin cancer. For this purpose, 92 Balb-c mice were distributed into 6 groups as control, CaFB, DMBA/TPA (D-T), treatment 1 (T1), 2 (T2), and 3(T3). Apart from control and CaFB in other groups, tumors initiated with 97.5-nmol DMBA and 6.5-nmol TPA. Treatment groups received 3 mg/kg/day CaFB with DMBA (T1), with TPA (T2), and after tumor formation (T3). In the D-T group, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) activity, 6-phosphogluconate dehydrogenase (PGD), glutathione (GSH), interleukin 6 (IL-6), (IL-1β), tumor necrosis factor-α (TNF-α) levels increased (p < 0.001) while malondialdehyde (MDA) levels decreased (p < 0.001) compared with that in control. CaFB application ameliorated DMBA-TPA effect according to the distribution time. It is noteworthy to consider CaFB as a potential preventive agent in skin cancer development.

Abstract
OBJECTIVES This study aimed to find out the protective effects and preliminary mechanisms of the flower extract of Caragana sinica (FEC) on dextran sulfate sodium salt (DSS)-induced colitis. MATERIALS AND METHODS The ulcerative colitis models of mice induced by 3% DSS were established and treated with FEC. Body weight changes, disease activity index (DAI), colon histopathological score, anti-oxidant ability, and the level of inflammatory cytokines were determined. The expression of Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) were assessed in colonic tissue by immunohistochemical staining. Western blot was used to analyze the expression of TLR4/ nuclear factor kappa-B (NF-κB) and TLR4/ mitogen-activated protein kinase (MAPK) signaling pathway-related proteins. RESULTS FEC significantly prevented body weight loss and colonic shortening and reduced the disease activity index and histopathological score (P<0.05). Moreover, FEC treatment remarkably down-regulated the levels of myeloperoxidase (MPO), interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α), and interleukin 6 (IL-6) and up-regulated the levels of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and interleukin 10 (IL-10) in the colon of DSS mice (P<0.05). Furthermore, the expression of TLR4/NF-κB and TLR4/MAPK pathway-related proteins was inhibited by FEC (P<0.05). CONCLUSION Our findings demonstrated that FEC could serve as a potential therapeutic agent for treatment of ulcerative colitis.

Abstract
In the present study, we have investigated and/or compared the role of glibenclamide, G as cystic fibrosis transmembrane conductance regulator (CFTR) inhibitor, and lubiprostone, L as chloride channel-2 (ClC-2) activator in the 2,4-dinitrobenzene sulfonic acid (DNBS)-induced gastrointestinal inflammation. GI inflammation was induced by intrarectal administration of DNBS. Rats were randomly allocated in 5 groups as sham control, distilled water + DNBS, sulfasalazine (S) + DNBS, G + DNBS, and L + DNBS. All the groups were pre-treated successively for five days before the induction of colitis. One day before and the first four days after DNBS administration various parameters were studied. Later, blood chemistry, colon’s gross structure, histology, and the antioxidant load was examined. Pre-treatment with G significantly protected the change induced by DNBS concerning the change in body weight, food intake, diarrhea, occult blood in the feces, wet weight of the colon, and spleen. G because of its anti-inflammatory property down-regulated the neutrophil and WBC count and up-regulated the lymphocyte number. Moreover, G efficiently ameliorates the oxidative stress in the colon and declines the level of myeloperoxidase and malondialdehyde and up-regulated the level of superoxide dismutase and glutathione. Lubiprostone has not shown any promising effects, in fact, it causes an increase in diarrheal frequency. Our findings from this study represent that G has good potential to ameliorate GI inflammation induced by DNBS by its multiple actions including CFTR blockage and reducing the release of inflammatory markers from the MCs, anti-inflammatory and free radical scavenging property.

Abstract
BACKGROUND Oxidative stress in children with type 1 DM (T1DM) may negatively affect the bone. METHODS This study included 40 children with T1DM as the patient group and 40 healthy children of matched age and sex as the control group. Plasma alkaline phosphatase, procollagen type-1 amino-terminal propeptide (P1NP), and urinary deoxypyridinoline (DPD) were measured to assess bone turnover. Glutathione, superoxide dismutase (SOD), and malondialdehyde (MDA) were measured to assess oxidative stress. RESULTS Patients with T1DM had a significantly lower P1NP level but a significantly higher urinary DPD level compared to the control group. Moreover, there were significantly lower glutathione and SOD levels with significantly higher MDA levels in patients with T1DM. We found a significant positive correlation between P1NP level and both glutathione and SOD levels but a significant negative correlation between P1NP and MDA in patients with T1DM. There was a significant negative correlation between DPD levels and both glutathione and SOD levels and a significant positive correlation between DPD and MDA. Moreover, glutathione was a significant predictor for both P1NP and DPD levels, while MDA was a significant predictor for P1NP levels. CONCLUSIONS There is an association between oxidative stress and bone turnover markers in children with T1DM. IMPACT Oxidative stress can negatively affect bone but the exact relationship between oxidative stress and bone turnover in T1DM has not been previously studied in pediatrics. For the best of our knowledge, our study was the first to assess the relationship between oxidative stress and bone turnover in children with T1DM. We revealed that increased oxidative stress in children and adolescents with T1DM may be involved in the impairment of bone turnover process, so treatment strategies toward better glycemic control and decreasing oxidative stress may be beneficial in preventing and treating diabetic bone disease in these children.

Abstract
Deep vein thrombosis (DVT), a subset of venous thromboembolism (VTE), is a major preventable cause of morbidity and mortality worldwide. We aim to investigate changes in oxidative injury markers and the levels of antioxidant parameters in DVT patients. 50 DVT patients who were admitted to the cardiovascular surgery clinic with acute (<2 weeks) or chronic (≥4 weeks) DVT and 100 healthy individuals were included. As oxidative injury marker malondialdehyde and the antioxidant parameters including reduced glutathione, glutathione peroxidase, catalase, and superoxide dismutase were analysed in the collected peripheral blood samples. Demographic characteristics of the acute and chronic DVT patients were similar (P>0.05). In all DVT patients having thrombosis in the distal and proximal leg veins the mean malondialdehyde and glutathione peroxidase activity were significantly increased, but superoxide dismutase activity significantly decreased, compared to the healthy controls (P<0.05). No difference was observed between distal and proximal DVT patient groups. The increased levels of malondialdehyde in our study is considered to result from the significant decrease in the antioxidant enzyme activity of superoxide dismutase. Furthermore, we are of the opinion that the increased levels of glutathione peroxidase enzyme activity observed in all patients could not compensate the reduction in the superoxide dismutase activity, thereby being insufficient in preventing the increase in the malondialdehyde levels.

Abstract
Gaucher disease is an autosomal recessive metabolic disorder caused by mutations in GBA1, which encodes for the lysosomal hydrolase enzyme, β-glucocerebrosidase. The resulting misfolded protein can trigger endoplasmic reticulum stress and an unfolded protein response within the affected cells. The enzyme deficiency leads to accumulation of its substrates, glucosylceramide and glucosylsphingosine, within macrophage lysosomes and with prominent disease manifestations in macrophage rich tissues. Resultant lysosomal pathology and impaired autophagy leads to redox imbalance, mitochondrial dysfunction and intracellular oxidative stress. Here we have systematically examined a role for oxidative stress in individuals affected by Gaucher disease. We compared multiple oxidative stress biomarkers in plasma and red blood cell samples from patients who are currently untreated, with those who are stable on standard-of-care therapy, and with healthy controls. We found significant differences in key oxidative stress biomarkers in untreated patients compared to healthy control. In treated patients, results generally fell between the controls and the untreated patients. Interestingly, even asymptomatic and minimally symptomatic untreated patients had evidence of significant systemic oxidative stress. We conclude that underlying oxidative stress may contribute to Gaucher disease pathophysiology including long-term adverse outcomes such as Parkinsonism and malignancies. Therapies targeting oxidative stress may prove useful as adjuvant treatments for Gaucher disease and other lysosomal storage disorders.

Anticolitic Effect of Berberine in Rat Experimental Model: Impact of PGE2/p38 MAPK Pathways. Mediators Inflamm 2020; 2020:9419085.

Abstract
Berberine (BER), a natural isoquinoline alkaloid, has been demonstrated to have appreciable anticolitis effects. Nevertheless, the protective mechanism of BER in ulcerative colitis (UC) is barely understood. The present study was aimed at exploring the therapeutic efficacy of BER on UC in experimental colitis rat model. Rats were orally administered with BER for seven days at low and high doses (25 and 50 mg/kg/day) before AcOH intracolonic instillation. BER significantly retrieved colon inflammation and mucosal damage indicated by inhibition of macroscopic score and lessened the levels of inflammatory biomarkers (IL-1β, IL-6, TNF-α, MPO, and PGE2). Notable downregulation of mRNA expression of p38 MAPK and increased protein expression of TGF-β were achieved by BER treatment. The anti-inflammatory potential of BER was supported by the histopathological screening of colon mucosa. In addition, BER restored colonic antioxidant capacity through elevation of GSH level and antioxidant enzymatic activities (SOD, CAT, GPx, and GR) together with reductions of both MDA and NO levels. Marked downregulation of Nos2 mRNA expression is accompanied by increased Nrf2 and Hmox-1 expressions in colon specimens treated by BER. Furthermore, BER exhibited noticeable antiapoptotic activities through decreasing proapoptotic proteins (Bax and caspase-3) and lessening antiapoptotic Bcl-2 protein in the colon mucosa. Based on these findings, BER may improve colitis markedly which may be mediated by its striking antioxidant, anti-inflammatory, and antiapoptotic properties.

Abstract
Multifunctionalities linked with the microbial communities associated with the millet crop rhizosphere has remained unexplored. In this study, we are analyzing microbial communities inhabiting rhizosphere of kodo millet and their associated functions and its impact over plant growth and survival. Metagenomics of Paspalum scrobiculatum L.(kodo millet) rhizopshere revealed taxonomic communities with functional capabilities linked to support growth and development of the plants under nutrient-deprived, semi-arid and dry biotic conditions. Among 65 taxonomically diverse phyla identified in the rhizobiome, Actinobacteria were the most abundant followed by the Proteobacteria. Functions identified for different genes/proteins led to revelations that multifunctional rhizobiome performs several metabolic functions including carbon fixation, nitrogen, phosphorus, sulfur, iron and aromatic compound metabolism, stress response, secondary metabolite synthesis and virulence, disease, and defense. Abundance of genes linked with N, P, S, Fe and aromatic compound metabolism and phytohormone synthesis—along with other prominent functions—clearly justifies growth, development, and survival of the plants under nutrient deprived dry environment conditions. The dominance of actinobacteria, the known antibiotic producing communities shows that the kodo rhizobiome possesses metabolic capabilities to defend themselves against biotic stresses. The study opens avenues to revisit multi-functionalities of the crop rhizosphere for establishing link between taxonomic abundance and targeted functions that help plant growth and development in stressed and nutrient deprived soil conditions. It further helps in understanding the role of rhizosphere microbiome in adaptation and survival of plants in harsh abiotic conditions.

Abstract
OBJECTIVE Resveratrol (RSV) is a natural polyphenol with putative anti-obesity effects; however, its mechanisms of action remain unclear due to its low bioavailability. Microbial functions in the physiology result from the microbiota-host coevolution has profoundly affected host metabolism. Here, we sought to determine how beneficial microbiome caused by RSV interventions affects antiobesity. METHODS C57BL/6J mice were fed either standard diet (SD) or RSV (300 mg/kg/day) diet for 16 weeks. The composition of the gut microbiota was assessed by analyzing 16S rRNA gene sequences. Then, transplant the RSV-microbiota to high-fat diet (HFD)-fed mice (HFD-RSVT) to explore the function of microbiota. Body weight and food intake were monitored. Markers of lipid metabolism, inflammation, gut microbiota compostion, and intestinal barrier were determined. RESULTS Mice treated with RSV shows a remarkable alteration in microbiota composition compared with that of SD-fed mice and is characterized by an enrichment of Bacteroides, Lachnospiraceae_NK4A136_group, Blautia, Lachnoclostridium, Parabacteroides, and Ruminiclostridium_9, collectively referred to as RSV-microbiota. We further explored whether RSV-microbiota has anti-obesity functions. Transplantation of the RSV-microbiota to high-fat diet (HFD)-fed mice (HFD-RSVT) was sufficient to decrease their weight gain and increase their insulin sensitivity. Moreover, RSV-microbiota was able to modulate lipid metabolism, stimulate the development of beige adipocytes in WAT, reduce inflammation and improve intestinal barrier function. CONCLUSIONS Our study demonstrates that RSV-induced microbiota plays a key role in controlling obesity development and brings new insights to a potential therapy based on host-microbe interactions.

Abstract
Colitis is a chronic inflammation and ulcer on the inner lining of the large intestine. For many centuries Ocimum gratissimum (OG) leaves have been used in folk medicine in Nigeria to treat inflammatory bowel diseases, however, to date, the anti-colitis effects of OG have not been scientifically proven. In this study we investigated the effects of polyphenol rich extract of Ocimum gratissimum (PREOG) leaf on colonic mucosa injury in colitis, its mechanisms, initial administration time and dosage. Dextran sodium sulfate (DSS)-induced rat colitis models was used. PREOG administration was initiated at 3 and 7 d after the model was established at doses of 200, 400 and 800 mg/kg for 7 d. 5-aminosalicylic acid (5-ASA) was used as a reference drug. The disease activity index (DAI), vascular permeability, markers of oxidative stress, granulocyte infiltration, inflammation and histopathological alteration were evaluated. Obvious colonic inflammation and mucosa injuries were observed in DSS-induced colitis groups. PREOG administration promoted repair of colonic mucosa injuries, attenuated inflammation, and decreased DAI scores in rats with colitis. PREOG also decreased the plasma concentrations of Interleukin-(IL)-6 and tumor necrosis factor (TNF)-α, and concentrations of myeloperoxidase, nitric oxide, cyclooxygenase-2 and malondialdehyde in the colon, and increased the plasma concentrations of IL-4 and IL-10 as well as the concentration of superoxide dismutase, catalase and reduced glutathione in the colon. The efficacy of PREOG was dosage dependent. In conclusion, OG repairs colonic mucosa injury in experimental colitis through its ant-inflammatory and ant-oxidant. Its efficacy related to initial administration time and dose.

Abstract
Background and Aim Ischemia-reperfusion (I/R) injury frequently occurs in different situations. Female sex hormones have a protective function. The purpose of this study was to determine the function of female sexual hormones on the gastric damage induced by I/R in male rats. Methods Forty (40) Wistar rats were randomized into five groups: intact, ischemia- reperfusion (IR), IR + estradiol (1mg/kg), IR + progesterone (16 mg / kg) and IR + combination of estradiol (1mg / kg) and progesterone (16 mg/ kg). Before the onset of ischemia and before reperfusion all treatments were done by intraperitoneal (IP) injection. After animal anesthesia and laparotomy, celiac artery was occluded for 30 minutes and then circulation was established for 24 hours. Results expressed as mean ± SEM and P <0.05 were considered statistically significant. Results The Glutathione (GSH) concentration significantly decreased after induction of gastric IR (P<0.001). Estradiol (P<0.001) and combined estradiol and progesterone (P<0.001) significantly increased GSH levels. The myeloperoxidase (MPO) concentration significantly increased after induction of gastric IR (P<0.001). Different treatments significantly reduced MPO levels (P<0.001). The gastric acid concentration significantly increased after induction of gastric IR (P<0.001). Treatment with estradiol, progesterone (P<0.05) and combined estradiol and progesterone (P<0.01) significantly reduced gastric acid levels. Superoxide dismutase (SOD) concentration decreased after induction of gastric IR. The SOD levels were not significant. Conclusion These data suggested that female sexual steroids have a therapeutic effect on gastrointestinal ischemic disorders by reduction of MPO and gastric acid, and increasing gastric GSH & SOD levels following gastric IR.

Abstract
OBJECTIVE In this study, we elucidated the ameliorative effect of aqueous extract of leaves of Mumiju against acetic acid-induced experimental colitis in male rats. MATERIALS AND METHODS The animals were randomly divided into four groups (n=7) including I: control group, II: vehicle group (injected with 2 ml acetic acid (4%) intra rectally), III and IV: treatment groups which received Mumiju (250 mg/kg) orally or intraperitoneally for 4 consecutive days after ulcer induction. Ulcer index, severity of inflammation, colonic levels of superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA), and histological changes were recorded after the treatment regimen of 4 days. RESULTS The ulcer index, severity of inflammation and colonic MDA levels were increased following intrarectal instillation of acetic acid. Also, acetic acid significantly decreased the SOD and GSH levels. Treatment with Mumiju for 4 days exhibited significantly lowered oxidative stress, while elevated of SOD and GSH levels. Regenerative-healing patterns also was seen by histopathological findings after treatment with Mumiju. CONCLUSION The present investigation demonstrates that Mumiju could be regarded as a herb with potent therapeutic value in the amelioration of experimental colitis in laboratory animals by modulation of oxidant- antioxidant system.

Abstract
The present study aimed to assess the possible preventive and reparative effects of isoleucine (Ile) against copper (Cu)-induced oxidative stress in fish enterocytes in vitro. In experiment 1, enterocytes were preincubated with increasing concentrations of Ile (0, 50, 120, 190, 260, and 330 mg L-1) for 72 h followed by exposure to 6 mg L-1 Cu for 24 h. In experiment 2, the enterocytes were pretreated with 6 mg L-1 Cu for 24 h and then treated with 0-330 mg L-1 Ile for 72 h to investigate its potential reparative role. The results of experiment 1 showed that Cu exposure increased lactate dehydrogenase (LDH) activity and malondialdehyde and protein carbonyl (PC) content; these changes were completely suppressed by pretreatment with Ile at optimum concentrations (P < 0.05). Moreover, Ile pretreatment prevented the decrease in superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in the enterocytes exposed to Cu (P < 0.05). Additionally, cells exposed to Cu exhibited adaptive increases in glutathione-S-transferase (GST) activity. In experiment 2, the LDH activity and protein oxidation induced by Cu were completely reversed by Ile posttreatment. Meanwhile, the Cu-induced decrease in SOD, GPx, and GST activity was completely reversed by subsequent Ile treatment, but the reduced glutathione content was not restored. Collectively, these results indicate that Ile suppresses Cu-induced oxidative damage via preventive and reparative pathways in primary enterocytes and thus protects the structural integrity of enterocytes in fish.

Protective effect of Averrhoa bilimbi L. fruit extract on ulcerative colitis in wistar rats via regulation of inflammatory mediators and cytokines. Biomed Pharmacother 2017; 91:1113-1121. [PMID: 28531922 DOI: 10.1016/j.biopha.2017.05.057] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2016] [Revised: 04/26/2017] [Accepted: 05/10/2017] [Indexed: 12/22/2022] Open
Abstract
Ulcerative Colitis (UC) is a lingering type of Inflammatory Bowel Disease (IBD) which affects the colon mucosa. Ulcerative colitis is majorly associated with oxidative stress and inflammation in colon tissue leading to damage. Averrhoa bilimbi L. fruit is rich in antioxidant phytochemicals including Vitamin C. In the current research, we have evaluated the defence mechanism of Averrhoa bilimbi L. on Ulcerative Colitis (UC). Male wistar rats were treated with Averrhoa bilimbi L. fruit extract (50mg/kg/bwt and 100mg/kg/bwt) and a standard drug Sulfasalazine (100mg/kg/bwt) for 6 consecutive days via intra peritoneally. After one day fasting, rats were given single dose of 3% 2ml of acetic acid through anal (intra-anal) region to induce Ulcerative Colitis. The protective and therapeutic effect of fruit extract on UC was assessed by comparing the relevant changes observed in the normal and treated group. In treated group the level of mucosal injury was decreased (ulcer score - 2) when compared to the control group (ulcer score - 9). The abnormal increase observed in the inflammation mediator cytokines in control rats, i.e IL-1β, IL-6, TNF-α levels were decreased significantly (**p<0.01) in the Averrhoa bilimbi L. fruit extract treated groups. The increase in weights of the colon tissue and spleen of the control rats were found to be reduced in treated groups. The levels of inflammatory markers iNOS and COX-2 were also decreased in treated group significantly (**p<0.01) when compared with the control. Furthermore, the treatment with Averrhoa bilimbi L. fruit extract has shown a significant antioxidant activity in the UC condition by reducing the levels of NO and enhancing the levels of SOD and GSH in the colon tissue. These results demonstrate the effective anti-ulcerative colitis activity of the Averrhoa bilimbi L. fruit extract in experimental wistar rats.

Change in Free Radical and Antioxidant Enzyme Levels in the Patients Undergoing Open Heart Surgery with Cardiopulmonary Bypass. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2016; 2016:1783728. [PMID: 28101295 PMCID: PMC5214539 DOI: 10.1155/2016/1783728] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Revised: 11/07/2016] [Accepted: 11/29/2016] [Indexed: 01/24/2023]
Abstract
Objective. The purpose of this study is to determine the changes in oxidative damage and antioxidant parameters in open heart surgeries with cardiopulmonary bypass (CPB) in preoperative and early postoperative periods. Methods. A total of three consecutive arterial blood samples were obtained from the patients in the study group, in preoperative, early postoperative, and postoperative periods, respectively. Oxidative damage indicator (MDA) and antioxidant indicators (GPx, GSH, CAT, and SOD) were examined. Results. A statistically significant increase was observed in MDA level in postoperative period compared to preoperative and early postoperative periods. GSH levels and CAT activities increased significantly in early postoperative and postoperative periods. Analyses revealed an increase in GPx and SOD enzyme activities only in the postoperative period. Conclusion. Even though the increase in MDA level was suppressed by the increased GSH level and CAT activity like in early postoperative period, efficiency can be brought for the increases in insufficient significant antioxidant parameters in postoperative period by administering antioxidant supplements to the patients and thus the increase in MDA in postoperative period can be significantly suppressed.

Abstract
This study aimed to determine the possible preventive effects of dexmedetomidine on postoperative intra-abdominal adhesions. Dexmedetomidine is a highly selective and potent α2 adrenergic agonist with sedative, analgesic, anxiolytic, sympatholytic, hemodynamic, and diuretic properties. In recent years, investigations have shown that dexmedetomidine possesses secondary antioxidant and also anti-inflammatory effects. Thirty Wistar albino male rats were randomized and divided into 3 groups of 10 animals each: group 1, sham-operated; group 2, cecal abrasion + peritoneal dissection; group 3, cecal abrasion + peritoneal dissection followed by daily intravenous injection of 10 μg/kg dexmedetomidine for 10 days. The animals were killed on postoperative day 21. Blood and cecal samples were taken for biochemical and histopathologic evaluation. In this study, biochemical and pathologic parameters were significantly better in the cecal abrasion + peritoneal dissection + dexmedetomidine group when compared with the cecal abrasion + peritoneal dissection group. Tissue malondialdehyde, myeloperoxidase, total sulfhydryl, and catalase were found to be significantly different between the cecal abrasion/peritoneal dissection + dexmedetomidine and the cecal abrasion/peritoneal dissection groups. Plasma malondialdehyde and total sulfhydryl values were also statistically different between these groups (P < 0.05). Statistical analyses of mean pathologic scores showed that the histopathologic damage in the cecal abrasion/peritoneal dissection + dexmedetomidine group was significantly less than the damage in the control group (P < 0.05 for all pathologic parameters). The results of this study show that dexmedetomidine had a significant preventive effect on postoperative intra-abdominal adhesions. We concluded that these effects might be due to antioxidant and anti-inflammatory activities.

Abstract
The aim of the present study is to develop embelin-loaded enteric-coated microspheres and investigate their pharmacological potential in acetic acid induced ulcerative colitis. The optimized formulation of embelin-loaded microspheres has shown significant sustained release of embelin. Further this formulation significantly reduced the ulcer activity score and oxidative stress, and attenuated the inflammatory changes. Thus it may be concluded that embelin-loaded enteric-coated microspheres have shown delayed release capacity than plain embelin and exerts colon ulcer protective effect in rats.

Abstract
There is limited information on the scientific literature about the effect of in vitro exposure of fish sperm to pesticides. In vitro effect of cypermethrin on sperm quality and oxidative stress has not yet been fully investigated. Therefore, the effects of cypermethrin, a type II pyrethroid insecticide, on quality and oxidative stress of spermatozoa were examined in vitro. To explore the potential in vitro toxicity of cypermethrin, fish spermatozoa were incubated with different concentrations of cypermethrin (1.025, 2.05 and 4.1 μg/l) for 2 h. The motility rate and duration of sperm were determined after exposure to cypermethrin. Reduced glutathione (GSH), glutathione peroxidase (GSH-Px), catalase (CAT) and malondialdehyde (MDA) in spermatozoa were analyzed for determination of oxidant and antioxidant balance. Our results indicated that spermatozoa motility and duration significantly decreased with exposure to cypermethrin. Additionally, activity of GSH-Px (P<0.05) and MDA and GSH levels increased in a concentration-dependent manner while CAT activity decreased (P<0.05). Consequently, the oxidant and antioxidant status and sperm quality were affected by quantitative changes and different concentrations of cypermethrin.

Abstract
There is little information in the scientific literature about effect of in vitro exposure of fish spermatozoa to pesticides. In vitro effect of Lambda-cyhalothrin (LCT) on sperm quality and oxidative stress has not been fully explored yet. The effects of LCT, which is a synthetic pyrethroid insecticide, on quality and oxidative stress of spermatozoa were investigated in vitro due to extensively use to control a wide range of insect pests in agriculture, public health, and homes and gardens. To explore the potential in vitro toxicity of LCT, fish spermatozoa were incubated with different concentrations of LCT (0.6, 1.2 and 2.4 μg/L) for 2h. Reduced glutathione (GSH), glutathione peroxidase (GSH-Px), catalase (CAT) and malondialdehyde (MDA) in spermatozoa were analyzed for determination of oxidant and antioxidant balance. Our results indicated that the percentage and duration of sperm motility significantly decreased with exposure to LCT. Activity of GSH-Px and MDA (P<0.05) and GSH levels (P<0.05) increased in a concentration-dependent manner while CAT activity decreased (P<0.05). In conclusion, the oxidant and antioxidant status and sperm quality were affected by increasing concentrations of LCT.

Abstract
Ulcerative colitis is an inflammatory disorder characterized by neutrophils infiltration, oxidative stress, upregulation of pro-inflammatory mediators and cytokines. Cavidine possesses anti-inflammatory activity and has been used to treat various inflammatory diseases but its effect on ulcerative colitis has not been previously explored. The present study aims to evaluate the effect of cavidine on acetic acid-induced ulcerative colitis in mice. Colitis mice induced by intra-rectal acetic acid (5%, v/v) administration received cavidine (1, 5 and 10mg/kg, i.g) or sulfasalazine (500mg/kg, i.g) for seven consecutive days. After euthanized by cervical dislocation, colonic segments of mice were excised for clinical, macroscopic, biochemical and histopathological examinations. Results suggested treatment with cavidine significantly decreased mortality rate, body weight loss, disease activity index (DAI), wet colon weight, macroscopic and histological score when compared with that of acetic acid-induced controls. In addition, administration of cavidine effectively modulated expressions of MPO, GSH, SOD and MDA. Furthermore cavidine inhibited the level of TNF-α and IL-6 in the serum and colon tissue in response to the regulation of p65 NF-κB protein expression. All these results indicated cavidine exerts marked protective effect in experimental colitis, possibly by regulating the expression of oxygen metabolites, NF-κB and subsequent pro-inflammatory cytokines production.

Abstract
The aim of the study was to evaluate the effect of Pterocarpus marsupium (PM) on acetic acid (AA)-induced ulcerative colitis (UC) in rats. The rats were divided into five groups, each having six rats. PM extract 100 mg and 200 mg/kg was given orally to groups four and five, respectively, and standard drug sulfasalazine (100 mg/kg, p.o) to group three. Group two served as UC control animals, and group one control animals received vehicle for 7 days. UC was induced by administering AA (3 % v/v of 2 ml) to all the animals except group one. After 72 h, the animals were killed and the colon was dissected out for microscopic, clinical evaluation, histopathological study and biochemical estimation. PM (100 and 200 mg/kg)-treated group had significantly reduced colon inflammation and mucosal damage. The treatment also normalized the altered antioxidant enzyme levels (LPO, SOD and GSH). Histopathological studies support the effect. The protective effect of PM may be due to antiinflammatory and antioxidant properties.

Abstract
Aim of the present study is to develop embelin lipid nanospheres (LNE) for better treatment of ulcerative colitis. Embelin LNs were developed using soya bean oil/virgin coconut oil as liquid lipid carrier and soya/egg lecithin as stabilizer by hot homogenization followed by ultrasonication technique. The particle size of LNEs ranged from 196.1±3.57 to 269.2±1.05nm with narrow polydispersity index values whereas zeta potential was from -36.6 to -62.0mV. Embelin was successfully incorporated into lipid nanospheres with entrapment efficiency about 99%. There was no interaction between embelin and selected liquid lipids which was confirmed by FTIR studies. In vitro drug release studies performed using Franz diffusion cell and results showed sustained release of embelin. Embelin LNs were stabilized with egg and soya lecithin, embelin release from these LNs followed Higuchi model and first order model, respectively, however mechanism of drug release in both LNs was non-Fickian. In vivo studies were carried out using acetic acid induced ulcerative colitis rat model and results revealed that treatment with embelin LNs significantly reduced clinical activity and macroscopic scores compared to embelin conventional suspension. Treatment with embelin LNs decreased MPO, LDH and LPO levels, increased reduced GSH levels which indicated better treatment of ulcerative colitis was achieved. This was also confirmed by improved histopathological conditions. Thus embelin LNs could be favourably used for treatment of ulcerative colitis.

Abstract
BACKGROUND Oxidative stress plays an important role in the development of diabetic cardiomyopathy. Alpha-lipoic acid (ALA) is a powerful antioxidant that may have a protective role in diabetic cardiac dysfunction. AIM We investigated the possible beneficial effect of alpha-lipoic acid on diabetic left ventricular (LV) dysfunction in children and adolescents with asymptomatic type 1 diabetes (T1D). SUBJECTS AND METHODS Thirty T1D patients (aged 10-14) were randomized to receive insulin treatment (n = 15) or insulin plus alpha-lipoic acid 300 mg twice daily (n = 15) for four months. Age and sex matched healthy controls (n = 15) were also included. Patients were evaluated with conventional 2-dimensional echocardiographic examination (2D), pulsed tissue Doppler (PTD), and 2-dimensional longitudinal strain echocardiography (2DS) before and after therapy. Glutathione, malondialdhyde (MDA), nitric oxide (NO), tumor necrosis factor-alpha (TNF-alpha), Fas ligand (Fas-L), matrix metalloproteinase 2 (MMP-2), and troponin-I were determined and correlated to echocardiographic parameters. RESULTS Diabetic patients had significantly lower levels of glutathione and significantly higher MDA, NO, TNF-alpha, Fas-L, MMP-2, and troponin-I levels than control subjects. The expression of transforming growth factor beta (TGF-beta) mRNA in peripheral blood mononuclear cells was also increased in diabetic patients. Significant correlations of mitral e'/a' ratio and left ventricular global peak systolic strain with glutathione, MDA, NO, TNF-alpha, and Fas-L were observed in diabetic patients. Alpha-lipoic acid significantly increased glutathione level and significantly decreased MDA, NO, TNF-alpha, Fas-L, MMP-2, troponin-I levels, and TGF-beta gene expression. Moreover, alpha-lipoic acid significantly increased mitral e'/a' ratio and left ventricular global peak systolic strain in diabetic patients. CONCLUSION These findings suggest that alpha-lipoic acid may have a role in preventing the development of diabetic cardiomyopathy in type 1 diabetes.

Abstract
Inflammatory bowel diseases (IBD), including Crohn's disease and Ulcerative colitis (UC), are life-long and recurrent disorders of the gastrointestinal tract with unknown etiology. The present study is designed to evaluate the ameliorative effect of Bauhinia tomentosa during ulcerative colitis (UC). Three groups of animals (n=6) were treated with B. tomentosa (5, 10, 20 mg/kg B.wt respectively) for 5 consecutive days before induction of UC. UC was induced by intracolonic injection of 3% acetic acid. The colonic mucosal injury was assessed by macroscopic scoring and histological examination. Furthermore, the mucosal content of lipid peroxidation (LPO), reduced glutathione (GSH), nitric oxide (NO), glutathione peroxidase (GPx) and superoxide dismutase (SOD) activity confirms that B. tomentosa could significantly inhibit colitis in a dose dependent manner. The myeloperoxidase (MPO), tumor necrosis factor (TNF-α), inducible nitric oxide synthase (iNOS) expression studies and lactate dehydrogenase (LDH) assay also supported that B. tomentosa could significantly inhibit experimental colitis. The effect was comparable to the standard drug sulfasalazine. Colonic mucosal injury parallels with the result of histological and biochemical evaluations. The extracts obtained from B. tomentosa possess active substances, which exert marked protective effects in acute experimental colitis, possibly by regulating the antioxidant and inflammatory mediators.

Abstract
Reperfusion has always been "the emergency intervention" to ischemic tissue. For a given period of time, tissue injury due to ischemia and reperfusion is more serious than injury due to ischemia only. Groups were as: Group 1: 25 µg/kg dexmedetomidine + ischemia/reperfusion group. Group 2: 10 mg/kg yohimbine +25 µg/kg dexmedetomidine + ischemia/reperfusion group. Group 3: Ischemia/reperfusion (control) group. Group 4: Healthy rats. Rat ovaries were exposed to a 3-hour ischemia and then reperfusion ensured for 2 hours. After ischemia/reperfusion, total glutathione, malondialdehyde, 8-hydroxyguanine levels and histopathological investigation were studied. The highest total glutathione and the lowest malondialdehyde and DNA damage levels were determined in dexmedetomidine group when compared to control group. The difference between yohimbine + dexmedetomidine and the control group was insignificant. Dexmedetomidine protects the ovarian tissue of the rat from I/R injury. It is hypothesized that this protective effect of dexmedetomidine is mediated by the α-2 adrenergic receptors. Dexmedetomidine could be useful for attenuation of tissue damage after I/R and prevention of I/R-related complications.

Eur J Pharmacol 2010; 654:100-5. [PMID: 21185828 DOI: 10.1016/j.ejphar.2010.12.012] [Citation(s) in RCA: 63] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2010] [Revised: 11/18/2010] [Accepted: 12/09/2010] [Indexed: 01/13/2023]
Abstract
The aim of the present study is to evaluate the effect of embelin isolated from Embelia ribes on acetic acid induced colitis in rats. Experimental animals received embelin (25 and 50 mg/kg, p.o.) and sulfasalazine (100mg/kg, p.o.) for five consecutive days before induction of colitis by intra-rectal acetic acid (3% v/v) administration and the treatment continued up to 7 days. The colonic mucosal injury was assessed by clinical, macroscopic, biochemical and histopathological examinations. Embelin treatment significantly decreased clinical activity score, gross lesion score, percent affected area and wet colon weight when compared to acetic acid induced controls. The treatment also reduced significantly the colonic myeloperoxidase activity, lipid peroxides and serum lactate dehydrogenase and significantly increased the reduced glutathione. The histopathological studies also confirmed the foregoing findings. The protective effect may be due to its antioxidant and anti-inflammatory activities.

Antitumor activity against murine lymphoma L5178Y model of proteins from cacao (Theobroma cacao L.) seeds in relation with in vitro antioxidant activity. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2010; 10:61. [PMID: 20961452 PMCID: PMC2974655 DOI: 10.1186/1472-6882-10-61] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/16/2009] [Accepted: 10/20/2010] [Indexed: 01/12/2023]
Abstract
Background Recently, proteins and peptides have become an added value to foodstuffs due to new knowledge about its structural analyses as related to antioxidant and anticancer activity. Our goal was to evaluate if protein fractions from cacao seeds show antitumor activity on lymphoma murine L5178Y model. The antioxidant activity of these fractions was also evaluated with the aim of finding a correlation with the antitumor activity. Methods Differential extraction of proteins from unfermented and semi-fermented-dry cacao seeds was performed and characterized by SDS-PAGE and FPLC size-exclusion chromatography. Antitumor activity was evaluated against murine lymphoma L5178Y in BALB/c mice (6 × 104 cells i.p.), with a treatment oral dose of 25 mg/kg/day of each protein fraction, over a period of 15 days. Antioxidant activity was evaluated by the ABTS+ and ORAC-FL assays. Results Albumin, globulin and glutelin fractions from both cacao seed type were obtained by differential solubility extraction. Glutelins were the predominant fraction. In the albumin fraction, polypeptides of 42.3 and 8.5 kDa were found in native conditions, presumably in the form of two peptide chains of 21.5 kDa each one. The globulin fraction presented polypeptides of 86 and 57 kDa in unfermented cacao seed that produced the specific-cacao aroma precursors, and after fermentation the polypeptides were of 45 and 39 kDa. The glutelin fraction presented proteins >200 kDa and globulins components <100 KDa in lesser proportion. Regarding the semifermented-dry cacao seed, it was observed that the albumin fraction showed antitumoral activity, since it caused significant decreases (p < 0.05) in the ascetic fluid volume and packed cell volume, inhibiting cell growth in 59.98 ± 13.6% at 60% of the population; while the greatest antioxidant capacity due to free radical scavenging capacity was showed by the albumin and glutelin fraction in both methods assayed. Conclusion This study is the first report on the biological activity of semifermented-dry cacao protein fractions with their identification, supporting the traditional use of the plant. The albumin fraction showed antitumor and free radical scavenging capacity, however both activities were not correlated. The protein fractions could be considered as source of potential antitumor peptides.
