Background/Aim. Although chlorpromazine (CPZ) is an antipsychotic drug widely used in clinical practice for a long time, its mechanism of action has not been entirely defined. An extremely difficult managing of patients acutely poisoned with CPZ is additional reason for detailed studying its toxicity mechanisms. In this clinical study, we investigated whether the oxidative stress (OS) mediates CPZ toxic effects in the exposed patients. Methods. The patients were organized into 3 groups: the T-group - hospitalized patients receiving therapeutic doses of 75-150 mg CPZ/day; the overdosed group, divided into two subgroups: the group M and the group S - mildly (CPZ serum concentration: 0.21 ? 0.05 mg/L) and severely (CPZ serum concentration: 2.66 ? 0.25 mg/L) poisoned patients, respectively, and the group C (control group of healthy volunteers). Oxidative stress parameters [total antioxidative status (TAS) and malondialdehyde (MDA) in plasma)] and superoxide dismutase (SOD) activity in erythrocytes were measured spectrophotometrically, and CPZ concentrations in serum were monitored chromatographically. One set of measurements was performed in the group C and T, whereas two sets of measurements (after 24 hours and 48 hours) were done in the poisoned patients, groups M and S. Results. A decrease of TAS and increase of SOD activity were obtained in both subgroups of the poisoned patients, compared to the controls and the group receiving therapeutic doses of CPZ. A significant increase of MDA was achieved in severely poisoned patients, compared to all other groups. Conclusion. Changed oxidative stress parameters in patients poisoned with chlorpromazine indicate involvement of oxidative stress in the toxicity mechanism(s) of chlorpromazine.

This study aimed to investigate the role of oxidative stress parameters (ROMs, OXY, SHp), the Oxidative Stress index (OSi), and High Mobility Group Box-1 protein (HMGB-1) in canine leishmaniosis (CanL). For this study, thirty dogs, naturally infected with Leishmania spp. (Leishmania Group, LEISH) and ten healthy adult dogs (control group, CTR) were included. The diagnosis of CanL was performed by a cytological examination of lymph nodes, real time polymerase chain reaction on biological tissues (lymph nodes and whole blood), and an immunofluorescence antibody test (IFAT) for the detection of anti-Leishmania antibodies associated with clinical signs such as dermatitis, lymphadenopathy, onychogryphosis, weight loss, cachexia, lameness, conjunctivitis, epistaxis, and hepatosplenomegaly. The HMGB-1 and oxidative stress parameters of the LEISH Group were compared with the values recorded in the CTR group (Mann Whitney Test, p < 0.05). Spearman rank correlation was applied to evaluate the correlation between the HMGB-1, oxidative stress biomarkers, hematological and biochemical parameters in the LEISH Group. Results showed statistically significant higher values of SHp in the LEISH Group. Specific correlation between the ROMs and the number of red blood cells, and between HGMB-1 and SHp were recorded. These preliminary data may suggest the potential role of oxidative stress in the pathogenesis of CanL. Further studies are undoubtedly required to evaluate the direct correlation between inflammation parameters with the different stages of CanL. Similarly, further research should investigate the role of ROMs in the onset of anemia.

Abstract Nicotine is a potential inducer of oxidative stress, through which it can damage numerous biological molecules. The aim of our study was to investigate the prooxidative effects of nicotine and protective (additive or synergistic) effects of quercetin and vitamin C in the blood of experimental animals, to determine whether the combination of these antioxidants might be beneficial for clinical purposes. Wistar albino rats were receiving intraperitoneal nicotine injection (0.75 mg kg-1 per day) or saline (control group) or nicotine plus quercetin (40 mg kg-1 per day) and vitamin C (100 mg kg-1 per day) for three consecutive days. On day 4, we determined their blood lipid profile, liver enzymes, oxidative stress parameters, and antioxidative system parameters. Compared to untreated control, nicotine significantly increased total cholesterol, LDLcholesterol, triglycerides, liver enzymes (alanine transaminase, aspartate transaminase, and lactate dehydrogenase) and oxidative stress parameters (superoxide anion, hydrogen peroxide, and lipid peroxide) and decreased HDL-cholesterol, glutathione, and superoxide dismutase/catalase activity. Quercetin + vitamin C reversed these values significantly compared to the nicotine alone group. Our results confirm that nicotine has significant prooxidative effects that may disrupt the redox balance and show that the quercetin + vitamin C combination supports antioxidant defence mechanisms with strong haematoprotective activity against nicotine-induced toxicity. In practical terms, this means that a diet rich in vitamin C and quercetin could prevent nicotine-induced toxicity and could also be useful in the supportive care of people exposed to nicotine.

Our aim was to evaluate effect of etanercept on oxidative stress parameters in rats with experimental peritonitis and investigate the availability of etanercept usage in the treatment of peritonitis in the future. Twenty-eight rats were divided into four groups as control (group 1), peritonitis (group 2), peritonitis + cefazolin sodium (group 3), and peritonitis + cefazolin sodium + etanercept (group 4). Peritoneal tissue and blood samples were taken from all of the rats for histopathological and biochemical examination. The oxidative stress parameters were examined in blood and tissue samples. It was observed that rats with peritonitis benefit from cefazolin sodium treatment. Evaluating the effectiveness of etanercept was our main objective for this study. In this perspective, we compared group 3 and group 4 and found statistically significant decreases in oxidative parameters and statistically significant increases in antioxidants in serum and tissue samples in group 4. It is observed that there was a significant contribution of etanercept on biochemical and also histopathological results. As a result, the TNF-αinhibitor, etanercept, in addition to antibiotics given in the early treatment of peritonitis results in more significant improvement of histopathological and oxidative parameters as compared to antibiotics alone.

Purpose: To determine the hepatoprotective potential of ethanol extracts of desi and kabuli cultivars of Cicer arietinum L. (chick peas). Methods: Hepatotoxicity was induced in rats using oral administration of carbon tetrachloride (CCl4). The rats were then orally administered different doses of the ethanol extracts of desi and kabuli cultivars of Cicer arietinum L. for 21 days. Oxidative stress parameters and hepatoprotective profiles were determined in serum samples using standard procedures. The effect of the treatments on liver histology was also determined. Results: Administration of extracts of desi and kabuli cultivars of Cicer arietinum L. to CCl4 treated rats at a dose of 300 mg/kg resulted in a significant (p ≤ 0.05) decrease in oxidative stress parameters, whereas catalase activity significantly increased (p ≤ 0.05); on the other hand, ALT and AST levels were decreased significantly (p ≤ 0.05), when compared to the control group. Conclusion: High doses of Cicer arietinum L (desi and kabuli cultivars) seem to have hepatoprotective and antioxidant effects on CCl4-induced toxicity in rats. This finding underscores the therapeutic importance of Cicer arietinum L. as a plant with hepatoprotective properties. Keywords: Cicer arietinum, Phenolics, Hepatotoxicity, Chick peas, Catalase

Hormone D and its analogues display immunomodulatory activities providing a beneficial effect in immunoinflammatory diseases. The aim of this study was to assess the effect of alfacalcidol treatment on superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activity and glutathione (GSH) and malondialdehyde (MDA) levels in patients with active RA. Sixteen patients with active RA and twenty controls were enrolled in the study. Blood samples were taken before and after 12 weeks of alfacalcidol therapy (2 ?g/day). Oxidative stress parameters were determined spectrophotometrically and by flow cytometry assessment. Disease activity was assessed using DAS28 score. The results revealed that alfacalcidol treatment, significantly (p = 0.04) reduced SOD activity and CAT activity (p = 0.001) in RA patients. The activity of GPx was significantly lower in RA patients before treatment, compared to controls (p = 0.04). After therapy, GPx activity was restored to control levels, and GSH levels were significantly reduced (p = 0.01). MDA levels in patients at the beginning of the study protocol, remained significantly elevated compared to controls (p = 0.01). Alfacalcidol treatment decreased MDA levels in patients (p = 0.19). Furthermore, 12-weeks alfacalcidol therapy, changed the response of RA patients? PBMC to stimulation preventing the O2 - production and mitochondrial membrane depolarisation. After alfacalcidol treatment, significant clinical improvement was observed.

Background: There has been considerable interest in the potential health benefits of borage. Little information is available regarding the safety of this plant. The purpose of this study was to evaluate the impact of borage on the mouse heart. Methods: Different amounts of borage extract were injected in mice. The mice were randomly divided into 4 groups including group1 (Control group without injection), group2, 3 and 4 that received 12.5 mg/kg, 25 mg/kg and 50 mg/kg respectively for 28 days. Oxidative stress parameters (lipid peroxidation, total glutathione groups assay and cupric assay) and biochemical (Creatine kinase activity and total cholesterol) and hematology parameters were evaluated. Furthermore, histopathology study was carried out on heart tissues. Results: We found that there was no significant difference in oxidative stress parameters and biochemical parameters between the control group and the groups that received different amounts of borage extract. There were also no changes in histopathology study. In blood parameters, the level of erythrocytes, hematocrit and hemoglobin decreased to 50mg/kg, whereas the level of MCH and MCV decreased in high doses. Conclusion: This article suggested that borage did not cause significant damage to the heart tissue in mice model. In hematology factors, significant changes were observed in erythrocytes and related parameters. Therefore, hematotoxicity of consumption this plant should be considered at high doses.

Eighty adult male hamsters were used in this study, 20 of them were divided equally into a noninfected, nontreated control group and chronic lead exposed groups, which were given lead acetate intraperitoneally, dissolved in distilled water, 2 mg/kg/day for seven weeks. Then, two experiments were carried out on the remaining animals. Each experiment included 30 animals and was divided equally into three groups. Experiment A was carried out on the following groups: Schistosoma mansoni infected group, S. mansoni infected and chronic lead exposed group and S. mansoni infected, chronic lead exposed and ‘Antox’ treated group. Experiment B was done following the same design except that infection was carried out using Schistosoma haematobium cercaria. Chronic lead exposure of Schistosoma infected groups showed significant reductions in worm burden, tissue egg load and ova excretion in stool, liver and intestine. Compared with the control group, there were insignificant increases in serum and hepatic glutathione and malondialdehyde levels and a significant increase in hepatic 8-oxodeoxy guanosine phosphate (8-Ox-Dg) levels in Schistosomainfected groups. However, there was a significant increase in hepatic and blood lead levels, oxidative stress parameters and in the hepatic 8-Ox-Dg level in Schistosoma infected and chronic lead exposed groups as compared with their corresponding Schistosoma only infected groups. This study revealed a significant reduction in oxidative stress parameters as well as in blood and hepatic lead levels and in hepatic 8-Ox-Dg levels after giving Antox to the Schistosoma infected and chronic lead exposed groups. However, Antox increased insignificantly all the parasitological parameters studied in the Schistosoma infected and chronic lead exposed groups.

Abstract Objective: The aim of this study was to evaluate the effects of hydraulic calcium silicate endodontic cements, MTA Angelus, MTA Fillapex, and Theracal LC, on erythrocyte and liver oxidative stress parameters of rats. Methods: Right upper incisor of each rat was extracted and polyethylene tubes containing the dental cements, or left empty for the control group, were inserted into the extraction socket. Blood and liver samples of each animal were obtained after 7, 30, or 60 days. Thiobarbituric acid reactive substances (TBARS) levels and catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activities were determined by spectrophotometry. Results: Erythrocyte and liver TBARS levels, and CAT and SOD enzymatic activities were significantly increased in dental cement applied groups compared with controls on day 7. The highest erythrocyte and liver TBARS concentrations were observed in the MTA Angelus group on day 7 of exposure. On day 30, erythrocyte CAT activity remained markedly high, but the other parameters returned to almost normal levels. On day 60, all parameters were similar between the control and the experimental groups. Conclusions: This is the first study to show that TBARS levels and antioxidant enzyme activities are transiently increased as a result of dental cement application.

ABSTRACT BACKGROUND: Ostomy is a surgical procedure that creates a stoma that aims to construct a new path for the output of feces or urine. The relationship of oxidative stress (OxS) markers in patients with ostomy is still poorly described. OBJECTIVE: The present study was aimed at investigating the changes in oxidative stress parameters in peripheral blood collected from ostomy patients when compared with a healthy control group. METHODS: It was evaluated 29 ostomy patients and 30 healthy control patients. The oxidative stress parameters evaluated were: lipid peroxidation [lipid hydroperoxide (LPO), 8-isoprostane (8-ISO) and 4-hydroxynonenal (4-HNE)], protein oxidation and nitration [carbonyl and 3-nitrotyrosine (3-NT)] and DNA oxidation [8-hydroxy-2’-deoxyguanosine (8-OHDG)] in serum from ostomy patients compared to health controls. RESULTS: The data showed an increase of LPO, 8-ISO, 4-HNE, 3-NT and 8-OHDG in serum collected from ostomy patients when compared to healthy controls. CONCLUSION: The findings support the hypothesis that ostomy triggers the oxidative stress observed in the blood collected from these patients.

The risk for cardiovascular diseases and type 2 diabetes mellitus significantly increases in the patient population with metabolic syndrome (MeS). The present study aimed to investigate the association between the epicardial adipose tissue thickness (EATT) and the oxidative stress parameters in MeS patients. The study included 181 patients as a patient group of 92 consecutive patients with MeS and a control group of 89 consecutive patients with similar age and gender. EATT was evaluated by transthoracic echocardiography. Serum levels of total oxidant status (TOS), total antioxidative capacity (TAS), paraoxonase-1 (PON-1), and arylesterase activities were measured. EATT was higher in the MeS group compared to the control group (6.0 ± 2.0 mm and4.0 ± 1.0 mm, resp.;P<0.001). The level of TOS was higher in the MeS group compared to the control group (P<0.001). Additionally, the TAS level was higher in the MeS group compared to the control group (P<0.001). Furthermore, the serum levels of PON-1 and arylesterase were lower in the MeS group compared to the control group (P<0.001). EAT may cause an increased risk of cardiovascular diseases by leading to increased oxidative stress in patients with MeS.
