Tartrazine is an azo dye which is widely used as colorant in foods, drugs and cosmetics.The aim of this study was to investigate the effect of tartrazine on biochemical and oxidative stress biomarkers on Swiss mice. Tartrazine was administered in drinking water at doses of 0%, 0.005% and 0.05% for 90 days. Both doses of tartrazine declined the body weight gain. In contrary, high dose increased glucose, total cholesterol (TC), triglycerides (TG), LDL, LDL/HDL and CT/HDL, transaminases, total protein (TP), total and direct bilirubin, , urea, creatinine, sodium and potassium levels. However, high dose of tartrazine decreased HDL, chloride, phosphorus and magnesium levels, whereas, tartrazine decreased calcium levels only in female. Both doses of tartrazine declined total antioxidant capacity. Protein carbonyls were in-creased in liver and kidney whith high dose. Liver and kidney superoxide dismutase (SOD) was decreased in male at low and high doses. However, liver SOD was reduced only in female at high dose. Oral administration of tartrazine affects liver and kidney functions as well as induces oxidative stress in mice. So, tartrazine consumption might be harmful to human health. It is necessary that people should be carefully consumed foods containing tartrazine.

Background: Taurine is a conditional essential nutrient in man, with proven antioxidant property. This study was designed to evaluate the protective effects of taurine against atrazine (ATZ)-induced hepatic and renal oxidative toxicity in rats.Methods: Wistar rats were orally exposed to ATZ (1/10 LD50) alone or in combination with taurine at 1.5% w/v and 3% w/v in their drinking water for 30 days. After treatment, the liver and kidney were excised for biochemical assays by spectrophotometric methods.Results: Exposure to ATZ significantly elevated hepatic and renal malondialdehyde (MDA) levels when compared to control (p < 0.05). Advanced oxidized protein products (AOPP) were equally increased in these tissues on exposure to ATZ. In addition, reduced glutathione (GSH) and total antioxidant capacity (TAC) were markedly depleted in both organs on exposure to ATZ. Furthermore, activities of the antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT) were inhibited by ATZ compared to the control. However, co-treatment with taurine attenuated the oxidative responses generated by ATZ exposure in the rats, with the high dose of the amino acid normalizing most of the toxic effects.Conclusion: The study suggested that taurine can protect against ATZ-induced oxidative stress.

Background: Cigarette smoke free radicals can cause cellular damage and different diseases. All the body fluids have antioxidants which protect against free radicals. Objective: The aim of this study was to evaluate salivary total antioxidant capacity and peroxidase, uric acid and malondialdehyde levels in smokers and a nonsmoking control group. Methods: Unstimulated saliva was collected from 510 males. A total of 259 subjects were current smokers and 251 were non-smokers. The levels of salivary total antioxidant capacity, uric acid, peroxidase and malondialdehyde were measured using standard procedures. Data were analyzed with t test and ANOVA. Results: The smokers were younger and dental hygiene index was higher than healthy nonsmoking controls. The mean total antioxidant capacity in smokers and nonsmokers was 0.13±0.07 and 0.21±011, respectively (P=0.001). Smokers had significantly lower peroxidase and uric acid levels than healthy controls. In addition, the mean malondialdehyde levels in the smokers and nonsmokers were 4.55 ±2.61 and 2.79 ±2.21, respectively (P=0.001). Conclusion: Cigarette smoke produces free radical and oxidative stress, causing many side effects. Salivary antioxidant levels decreased and malondialdehyde levels increased in smokers, indicating the high oxidative stress among smokers compared to nonsmokers. Cigarette smoke had deleterious effects on main salivary antioxidants levels.

The effects of ascorbic acid supplementation on biomarkers of oxidative stress, cadmium accumulation in organs, immune system activity and kidney function in chickens were investigated. The treatment groups of chickens were fed either plain diet or diet supplemented with ascorbic acid at 100, 500, 1000 and 2000 mg/kg for four weeks. Liver and kidney tissues were assayed for cadmium concentration, and the hepatic levels of ascorbic acid and dehydroascorbic acid (DHAA; the oxidised form), malondialdehyde, glutathione, activity of glutathione peroxidase, blood serum uric acid, creatinine, lysozyme and circulating immune complexes were measured. Supplementation with a high dose of ascorbic acid (1000 and 2000 mg/kg in the diet) caused an imbalance between pro-oxidative and antioxidative activities, and induced a suppressive effect on innate immunity. The results suggest that oxidative stress compromises renal function. We observed that ascorbic acid increased cadmium accumulation in a dose-dependent manner.

To investigate the effect of B-ultrasound-guided nerve block on analgesia and sedation in patients with acute cholecystitis undergoing puncture and drainage. Methods 96 patients with acute cholecystitis who underwent puncture and drainage from May 2018 to November 2020 were randomly divided into control group and observation group by random number table method, with 48 cases in each group. The patients in the control group were anesthetized by local infiltration. The patients in the observation group were anesthetized by B-ultrasound-guided nerve block. Heart rate, blood pressure, analgesia score, sedation score, and oxidative stress level were compared between the two groups. Results At the time of puncture (T2), heart rate (HR) and mean arterial pressure (MAP) in the two groups were significantly lower than those before operation (T1) (P<0.05); at the end of operation (T3), HR and MAP in the control group were significantly higher than those at T1 (P<0.05); at T2, HR and MAP in the observation group were significantly higher than those in the control group (P<0.05); at T3, HR and MAP in the observation group were significantly lower than those in the control group (P<0.05). AtT2 and T3, Ramsay sedation score in both groups was significantly lower than that at T1 (P<0.05), while Ramsay score in the observation group was significantly higher than that in control group (P<0.05); atT2 and T3, visual analog scale (VAS) pain score in both groups was significantly higher than that at T1 (P<0.05), while VAS score in the observation group was significantly lower than that in the control group (P<0.05). After operation, the levels of serum malondialdehyde (MDA) and superoxide dismutase (SOD) in the two groups were significantly higher than those before operation (P<0.05), and the levels of serum total antioxidant capacity (T-AOC) were significantly lower than those before operation (P<0.05); after operation, the levels of serum SOD and T-AOC in the observation group were significantly higher than those in the control group (P<0.05), and the levels of MDA in the observation group were significantly lower than those in the control group (P>0.05). Conclusion B-ultrasound-guided nerve block anesthesia can maintain the stable hemodynamic index of patients with acute cholecystitis undergoing puncture and drainage therapy, improve the analgesic and sedative effect and reduce the oxidative stress response of the body.

Hypoxic exercise is characterized by workloads decrements. Because exercise and high altitude independently elicit redox perturbations, the study purpose was to examine hypoxic and normoxic steady-state exercise on blood oxidative stress. Active males (n = 11) completed graded cycle ergometry in normoxic (975 m) and hypoxic (3,000 m) simulated environments before programing subsequent matched intensity or workload steady-state trials. In a randomized counterbalanced crossover design, participants completed three 60-min exercise bouts to investigate the effects of hypoxia and exercise intensity on blood oxidative stress. Exercise conditions were paired as such; 60% normoxic VO2peak performed in a normoxic environment (normoxic intensity-normoxic environment, NI-NE), 60% hypoxic VO2peak performed in a normoxic environment (HI-NE), and 60% hypoxic VO2peak performed in a hypoxic environment (HI-HE). Blood plasma samples drawn pre (Pre), 0 (Post), 2 (2HR) and 4 (4HR) hr post exercise were analyzed for oxidative stress biomarkers including ferric reducing ability of plasma (FRAP), trolox equivalent antioxidant capacity (TEAC), lipid hydroperoxides (LOOH) and protein carbonyls (PCs). Repeated-measures ANOVA were performed, a priori significance of p ≤ .05. Oxygen saturation during the HI-HE trial was lower than NI-NE and HI-NE (p < .05). A Time × Trial interaction was present for LOOH (p = .013). In the HI-HE trial, LOOH were elevated for all time points post while PC (time; p = .001) decreased post exercise. As evidenced by the decrease in absolute workload during hypoxic VO2peak and LOOH increased during HI-HE versus normoxic exercise of equal absolute (HI-NE) and relative (NI-NE) intensities. Results suggest acute hypoxia elicits work decrements associated with post exercise oxidative stress.

The aim of this study was to determine the effects of four essential oils intake by feed, namely Origanum vulgare, Thymus vulgaris, Cinnamomum zeylanicum Ness, and Syzygium aromaticum on antioxidant status in mice in vivo. Essential oils were in the aether oleum form. They were diluted with ethanol absolute mixed with ground pelett (0.1, 0.25, 0.57 and 1% concentration) and thereafter ethanol was evaporated. SOD, GPx activities and TAS were measured in erythrocytes and plasma spectrophotometrically with Ransod, Ransel and TAS kits from RANDOX, respectively. GPX activity showed a significant increase in 0.25% and 0.1% concentration of Origani aetheroleum. The GPx activities were decreased in 1% concentration of Thymi aetheroleum and 0.57% concentration of Cinnamomi aetheroleum and 0.57% concentration of Caryophylli aetheroleum. The total antioxidant status showed a significant decrease in 1 % concentration of Origani aetheroleum and significantly increased in 0.1% concentration. The same results were found in Thymi aetheroleum. Cinnamomi aetheroleum and Caryophylli aetheroleum had not effect on total antioxidant status. SOD activities were not significantly changed after intake of essential oils. In conclusion, our results showed, that concentration of essential oil is very important for antioxidant status and also for metabolism of mice, because a high dose of essential oil has adverse effect on metabolism of mice, representated by a lower growth of the body weight. On the other hand, essential oils at lower concentrations have positive effect on antioxidant status of mice.

Introduction: Oxidative stress is a key contributor to aging and age-related diseases. In the present study, we examine the protective effects of PFT, a novel kefir product, against age-associated oxidative stress using aged (10-month-old) mice. Methods: Mice were treated with PFT orally at a daily dose of 2 mg/kg body weight over 6 weeks, and antioxidant status, protein oxidation, and lipid peroxidation were studied in the brain, liver, and blood. Results: PFT supplementation significantly reduced the oxidative stress biomarkers malondialdehyde (MDA) and nitric oxide; reversed the reductions in glutathione (GSH) levels, total antioxidant capacity (TAC), and anti-hydroxyl radical (AHR) content; enhanced the antioxidant enzyme activities of glutathione peroxidase (GPx), catalase (CAT), and superoxide dismutase (SOD); inhibited the liver enzyme levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT); significantly reduced triglyceride (TG), total cholesterol (TC), and low density lipoprotein (LDL) levels; and significantly elevated high density lipoprotein (HDL) levels. Interestingly, PFT supplementation reversed the oxidative changes associated with aging, thus bringing levels to within the limits of the young control mice in the brain, liver, and blood. We also note that PFT affects the redox homeostasis of young mice and that it is corrected post-treatment with PFT. Conclusion: Our findings show the effectiveness of dietary PFT supplementation in modulating age-associated oxidative stress in mice and motivate further studies of PFT’s effects in reducing age-associated disorders where free radicals and oxidative stress are the major cause.

The Impact

Buprenorphine and methadone are two substances widely used in the substitution treatment of patients who are addicted to opioids. Although it is known that they partly act efficiently towards this direction, there is no evidence regarding their effects on the redox status of patients, a mechanism that could potentially improve their action. Therefore, the aim of the present investigation was to examine the impact of buprenorphine and methadone, which are administered as substitutes to heroin-dependent patients on specific redox biomarkers in the blood. From the results obtained, both the buprenorphine (n=21) and the methadone (n=21) groups exhibited oxidative stress and compromised antioxidant defence. This was evident by the decreased glutathione (GSH) concentration and catalase activity in erythrocytes and the increased concentrations of thiobarbituric acid reactive substances (TBARS) and protein carbonyls in the plasma, while there was no significant alteration of plasma total antioxidant capacity (TAC) compared to the healthy individuals (n=29). Furthermore, methadone revealed more severe oxidant action compared to buprenorphine. Based on relevant studies, the tested substitutes mitigate the detrimental effects of heroin on patient redox status; still it appears that they need to be boosted. Therefore, concomitant antioxidant administration could potentially enhance their beneficial action, and most probably, buprenorphine that did not induce oxidative stress in such a severe mode as methadone, on the regulation of blood redox status.

Abstract Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25 - 30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (AIP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examines for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function.

Background: Oxidative stress may play an important role in the pathogenesis of pulmonary tuberculosis (PTB). To our knowledge there is paucity of data on the status of oxidative stress biomarkers among PTB patients in Gombe, North-eastern Nigeria. Our study was designed to evaluate the oxidative stress biomarkers in pulmonary tuberculosis patients in Gombe, North-eastern Nigeria. Aims and Objectives: To determine the serum levels of oxidative stress biomarkers among patients with pulmonary tuberculosis in Gombe metropolis, North-eastern Nigeria and to assess the correlation between the oxidative stress biomarkers in pulmonary tuberculosis patients. Materials and Methods: A cross sectional comparative study was conducted in a tertiary health care facility with 40 pulmonary tuberculosis (PTB) patients on anti-TB drugs treatment (ATT), 40 newly diagnosed PTB patients not yet on anti-TB drugs treatment (ATT-naïve) and 40 age- and sex-marched apparently healthy subjects (controls). Serum total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA), nitric oxide (NO) and oxidative stress index (OSI) determined using standard techniques. Data was analysed using INSTAT® (Graph Pad Software Inc., La Jolla, CA, USA). Results: Serum levels of TOS, OSI, MDA and NO were significantly (p ˂ 0.001) increased in PTB patients (ATT and ATT-naïve) when compared with healthy individuals. Serum TAS and body mass index (BMI) were significantly (p ˂ 0.001) decreased in PTB patients when compared with healthy individuals. Serum TOS significantly correlated with serum OSI, MDA and NO in ATT-naïve PTB patients. Conclusion: This study observed an increased oxidative stress biomarkers and decreased total antioxidant status in newly diagnosed pulmonary tuberculosis patients and those on treatment. Our findings suggest that antioxidants supplementation and improved nutrition in the management of pulmonary tuberculosis patients may go a long way in preventing the oxidative onslaught and further complications in PTB patients.
