<p><span>The article presents the results of investigation of the impact of stress on oxidative intensity of lipid per oxidation. It was proved that intramuscular injection of 50% solution of tetrachloromethane at a dose of 0.25 mL per 100 g of rat body causes the activation of free radical lipid oxidation with excessive accumulation of intermediate and final products of lipid peroxidation. Our results indicate that the development of oxidative stress leads to the significant acceleration of the formation and accumulation of lipid hydroperoxides and malondialdehyde (MDA) in plasma of rats. We registered the highest level of lipid hydroperoxides in rat blood plasma under oxidative stress on the second day of the experiment; it was 0.843 un/mL, whereas this index was 0.245 un/mL in the control group.

Introduction: Diazinon (DZN) administration produces lipid peroxidation as an indicator of oxidative stress in the brain. Some medicinal plants such as Dorema glabrum has antioxidant properties, so can be used as an antioxidant that may protect neurons from oxidative stress. The aim of present study was to investigate the effect of D. glabrum against DZN-induced oxidative stress in hippocampus. Methods: Twenty-four adult male Wistar rats were used in this study. The rats randomly were divided into four groups including a control group, and two groups received different doses of D. glabrum (40 and 80 mg/kg) as pre-treatment for 21 days with DZN (100 mg/Kg) that was injected intraperitoneally (ip) in last day of D. glabrum usage, and one group received only DZN. Thiobarbituric acid reactive substances (TBARS), which are the indicators of lipid peroxidation, and the activities of antioxidant enzymes (glutathione peroxidase, superoxide dismutase and catalase) were determined in the ratsʼ hippocampus. Results: Administration of DZN significantly increased TBARS levels and superoxide dismutase activity and decreased glutathione peroxidase activity but there were no significant changes in catalase activity in the hippocampus. Combined D. glabrum and DZN treatment, caused a significant increase in glutathione peroxidase, a significant decrease of TBARS and a significant decrease in superoxide dismutase and again no significant changes in catalase activity in the rats’ hippocampus when compared to the rats treated with DZN. Conclusion: Our study demonstrated that D. glabrum had an amelioratory effect on oxidative stress induced by DZN.

Abstract Background Specific metabolic changes during physiological pregnancy are characterized by hyperlipidemia and increased oxidative stress. However, these specific changes raise the question of their pro-atherogenic potential during pregnancy and their influence on the risk of developing cardiovascular disease (CVD) in women later in life, as well as complications during pregnancy. The aim of this study was to investigate the changes in lipid indexes and parameters of lipid peroxidation in non-complicated pregnancy in order to estimate their course of change and potential relationship during non-complicated pregnancy. Methods The study included 43 healthy pregnant women and 38 non-pregnant healthy women, in appropriate ages, as the control group. Lipid parameters and oxidative stress parameters were monitored in a longitudinal study in the first, second and third trimesters, and before delivery during non-complicated pregnancy. Results Results have shown that lipid indexes rise during pregnancy. The values were significantly increased when compared to the first trimester in all lipid indices and in comparison with the control group. Thyobarbituric acid reactive substances (TBARS) and lipid hydroperoxides (LOOH) were not changed significantly during physiological pregnancy, but LOOH showed a significantly higher value in the first trimester compared with the control group. Prooxidative-antioxidative balance (PAB) significantly increases as pregnancy progresses. Conclusions We observed the changes in lipids, lipid indexes and parameters that indicate oxidative modification of lipids in physiological pregnancy that may lead to an atherogenic, prooxidant state.

The Impact

The aim of the research was to assess the effectiveness of Antral regarding the impact on the intensity of lipid peroxidation, antioxidant system factors in NASH patients against the background of obesity and comorbidity with COPD. Material and methods of research: 76 NASH patients with class I obesity of and COPD 2-3 D were examined: 23 patients (group 1 – control group) received basic NASH therapy (Esentsiale forte N (Sanofi Avensis/Gutterman and Cie GmbH) 300 mg, 2 caps., 3 times per day) for 30 days and COPD therapy (Symbicort Turbuhaler (budesonide 160 mg/d + formoterol fumarate 4,5 mg/s) (AstraZeneca AB, Sweden) inhaled 2 times per day for 30 days, Berodual (ipratropium/fenoterol (250/500 mg/ml) (Institute de Angele Italy/Boehringer Ingelheim International GmbH) nebulizer inhalation 2 times per day, azithromycin (Azithro Sandoz, Ukraine Sandoz) 500 mg, 1 time per day for 10 days). The second group (basic group, B1) consisted of 25 NASH patients with class I obesity and COPD 2-3 D, in addition to the same basic COPD therapy, they received Antral (Farmak, Ukraine) 200 mg, 3 times per day for 60 days as a hepatoprotection. The third group (basic group, B2) included 28 NASH patients with class I obesity and COPD 2-3 D, except the same basic COPD treatment, they received Antral (Farmak, Ukraine) 200 mg, 3 times per day as a hepatoprotection, and Phytostatin (Polyconazole) (OmniFarma LLC, Ukraine) 20 mg after dinner for 30 days. Research results. In NASH patients against the background of obesity and COPD, a significant intensity of oxidative stress has been established with an increase in the blood of intermediate and final products of lipid peroxidation content (in 1.7–2.2 times, p < 0.05) against the background of a significant deficit in the restored glutathione in the blood (in 1.6 times, p < 0.05), which was accompanied by a compensatory voltage of catalase activity (increases in 1.7 times, p < 0.05). Conclusion. The combined prescription of Antral for 30 days led to a significant correction of oxidative-antioxidant homeostasis in NASH patients against the background of obesity and COPD with a probable decrease of malonic aldehyde, isolated double bonds, conjugated dienes (p < 0.05), a probable increase the reduced glutathione content in red blood cells (p < 0.05).

Acrylamide is a hazardous substance inducing oxidative stress. Based on some evidence on the antioxidant properties of fenugreek, Trigonella foenum-graecum, this study was conducted to investigate the protective effect of fenugreek seed oil against acrylamide toxicity. Thirty-two male Wistar rats were randomly assigned into four groups. The control group was given normal saline. The second group was administered acrylamide (20 mg/kg bw orally). The third and fourth groups were administered acrylamide (20 mg/kg bw) and supplemented with 2.5% and 5% fenugreek seed oil in their diets, respectively. Acrylamide intoxication significantly increased serum levels of LDH, AST, ALT, APL, γ-GT, cholesterol, uric acid, urea, creatinine, 8-oxo-2′-deoxyguanosine, interleukin 1 beta, interleukin 6, and tumor necrosis factor α. Moreover, it increased hepatic, renal, and brain lipid peroxidation, while it impaired the activities and concentrations of the antioxidant biomarkers. Fenugreek oil supplementation normalized the altered serum parameters, prevented lipid peroxidation, and enhanced the antioxidant biomarker concentrations and activities in the hepatic, renal, and brain tissues of acrylamide-intoxicated rats in a dose-dependent manner. Thus, these results indicate that Trigonella foenum-graecum oil has a protective effect against acrylamide-induced toxicity through its free radical scavenging and potent antioxidant activities.

Resistance of erythrocytes from Brown trout (Salmo trutta m. trutta L.) affected by ulcerative dermal necrosis syndrome In the present work we evaluated the effect of ulcerative dermal necrosis (UDN) syndrome on resistance of erythrocytes to haemolytic agents and lipid peroxidation level in the blood from brown trout (Salmo trutta m. trutta L.). Results showed that lipid peroxidation increased in erythrocytes, as evidenced by high thiobarbituric acid reactive substance (TBARS) levels. Compared to control group, the resistance of erythrocytes to haemolytic agents was significantly lower in UDN-positive fish. Besides, UDN increased the percent of hemolysated erythrocytes subjected to the hydrochloric acid, urea and hydrogen peroxide. Results showed that UDN led to an oxidative stress in erythrocytes able to induce enhanced lipid peroxidation level, as suggested by TBARS level and decrease of erythrocytes resistance to haemolytic agents.

Oxidative stress and neuroinflammation are involved in the pathogenesis and progression of glaucoma. Our aim was to evaluate the impact of selected single-nucleotide polymorphisms in inflammation and oxidative stress genes on the risk of glaucoma, the patients’ clinical characteristics and the glaucoma phenotype. In total, 307 patients with primary open-angle glaucoma or ocular hypertension were enrolled. The control group included 339 healthy Slovenian blood donors. DNA was isolated from peripheral blood. Genotyping was performed for SOD2 rs4880, CAT rs1001179, GPX1 rs1050450, GSTP1 rs1695, GSTM1 gene deletion, GSTT1 gene deletion, IL1B rs1143623, IL1B rs16944, IL6 rs1800795 and TNF rs1800629. We found a nominally significant association of GSTM1 gene deletion with decreased risk of ocular hypertension and a protective role of IL1B rs16944 and IL6 rs1800629 in the risk of glaucoma. The CT and TT genotypes of GPX1 rs1050450 were significantly associated with advanced disease, lower intraocular pressure and a larger vertical cup–disc ratio. In conclusion, genetic variability in IL1B and IL6 may be associated with glaucoma risk, while GPX and TNF may be associated with the glaucoma phenotype. In the future, improved knowledge of these pathways has the potential for new strategies and personalised treatment of glaucoma.

Urinary concentrations of 16 different exposure biomarkers to metals were determined at the beginning and at the end of a working shift on a group of workers in the metal carpentry industry. Five different oxidative stress biomarkers were also measured, such as the oxidation products of RNA and DNA metabolized and excreted in the urine. The results of workers exposed to metals were compared to those of a control group. The metal concentrations found in these workers were well below the occupational exposure limit values and exceeded the mean concentrations of the same metals in the urine of the control group by a factor of four at maximum. Barium (Ba), mercury (Hg), lead (Pb) and strontium (Sr) were correlated with the RNA oxidative stress biomarker, 8-oxo-7, 8-dihydroguanosine (8-oxoGuo), which was found able to discriminate exposed workers from controls with a high level of specificity and sensitivity. The power of this early diagnostic technique was assessed by means of the ROC curve. Ba, rubidium (Rb), Sr, tellurium (Te), and vanadium (V) were correlated with the level of the protein oxidation biomarker 3-Nitrotyrosine (3-NO2Tyr), and Ba, beryllium (Be), copper (Cu), and Rb with 5-methylcytidine (5-MeCyt), an epigenetic marker of RNA damage. These effect biomarkers can help in identifying those workers that can be defined as “occupationally exposed” even at low exposure levels, and they can provide information about the impact that such doses have on their health.

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

Inflammatory Autoimmune Disease

Rheumatoid arthritis (RA) is a highly debilitating chronic inflammatory autoimmune disease most prevalent in women. The true etiology of this disease is complex, multifactorial, and is yet to be completely elucidated. However, oxidative stress and lipid peroxidation are associated with the development and pathogenesis of RA. In this case, oxidative damage biomarkers have been found to be significantly higher in RA patients, associated with the oxidation of biomolecules and the stimulation of inflammatory responses. Lipid peroxidation is one of the major consequences of oxidative stress, with the formation of deleterious lipid hydroperoxides and electrophilic reactive lipid species. Additionally, changes in the lipoprotein profile seem to be common in RA, contributing to cardiovascular diseases and a chronic inflammatory environment. Nevertheless, changes in the lipid profile at a molecular level in RA are still poorly understood. Therefore, the goal of this review was to gather all the information regarding lipid alterations in RA analyzed by mass spectrometry. Studies on the variation of lipid profile in RA using lipidomics showed that fatty acid and phospholipid metabolisms, especially in phosphatidylcholine and phosphatidylethanolamine, are affected in this disease. These promising results could lead to the discovery of new diagnostic lipid biomarkers for early diagnosis of RA and targets for personalized medicine.

Abstract Background Fluoride may induce oxidative stress and apoptosis. It may also lead to neurobehavioural defects including neuromuscular damage. The present study aimed to explore the effects of sub lethal concentrations of sodium fluoride (NaF) on the lifespan and climbing ability of Drosophila melanogaster. In total, 0.6 mg/L and 0.8 mg/L of NaF were selected as sublethal concentrations of NaF for the study. Lifespan was measured and climbing activity assay was performed. Results The study showed significant decrease in lifespan of flies treated with fluoride. With increasing age, significant reduction in climbing activity was observed in flies treated with sodium fluoride as compared to normal (control) flies. Flies treated with tulsi (Ocimum sanctum) and NaF showed increase in lifespan and climbing activity as compared to those treated with NaF only. Lipid peroxidation assay showed significant increase in malondialdehyde (MDA) values in the flies treated with NaF as compared to control. The MDA values decreased significantly in flies treated with tulsi mixed with NaF. Conclusions The results indicate that exposure to sub lethal concentration of NaF may cause oxidative stress and affect the lifespan and climbing activity of D. melanogaster. Tulsi extract may help in reducing the impact of oxidative stress and toxicity caused by NaF.
