AB  - The alkaline comet assay, or single cell gel electrophoresis, is one of the most popular methods for assessing DNA damage in human population. One of the open issues concerning this assay is the identification of those factors that can explain the large inter-individual and inter-laboratory variation. International collaborative initiatives such as the hCOMET project - a COST Action launched in 2016 - represent a valuable tool to meet this challenge. The aims of hCOMET were to establish reference values for the level of DNA damage in humans, to investigate the effect of host factors, lifestyle and exposure to genotoxic agents, and to compare different sources of assay variability. A database of 19,320 subjects was generated, pooling data from 105 studies run by 44 laboratories in 26 countries between 1999 and 2019. A mixed random effect log-linear model, in parallel with a classic meta-analysis, was applied to take into account the extensive heterogeneity of data, due to descriptor, specimen and protocol variability. As a result of this analysis interquartile intervals of DNA strand breaks (which includes alkali-labile sites) were reported for tail intensity, tail length, and tail moment (comet assay descriptors). A small variation by age was reported in some datasets, suggesting higher DNA damage in oldest age-classes, while no effect could be shown for sex or smoking habit, although the lack of data on heavy smokers has still to be considered. Finally, highly significant differences in DNA damage were found for most exposures investigated in specific studies. In conclusion, these data, which confirm that DNA damage measured by the comet assay is an excellent biomarker of exposure in several conditions, may contribute to improving the quality of study design and to the standardization of results of the comet assay in human populations.

AB  - Alzheimer’s disease (AD) is a neurodegenerative disease that affects millions of individuals worldwide and can occur relatively early or later in life. It is well known that genetic components, such as the amyloid precursor protein gene on chromosome 21, are fundamental in early-onset AD (EOAD). To date, however, only the apolipoprotein E4 (ApoE4) gene has been proved to be a genetic risk factor for late-onset AD (LOAD). In recent years, despite the hypothesis that many additional unidentified genes are likely to play a role in AD development, it is surprising that additional gene polymorphisms associated with LOAD have failed to come to light. In this review, we examine the role of X chromosome epigenetics and, based upon GWAS studies, the PCDHX11 gene. Furthermore, we explore other genetic risk factors of AD that involve X-chromosome epigenetics.

AB  - To remedy carotid artery stenosis and prevent stroke surgical intervention is commonly used, and the gold standard being carotid endarterectomy (CEA). During CEA cerebrovascular hemoglobin oxygen saturation decreases and when this decrease reaches critical levels it leads to cerebral hypoxia that causes neuronal damage. One of the proposed mechanism that affects changes during CEA and contribute to acute brain ischemia (ABI) is oxidative stress. The increased production of reactive oxygen species and reactive nitrogen species during ABI may cause an unregulated inflammatory response and further lead to structural and functional injury of neurons. Antioxidant activity are involved in the protection against neuronal damage after cerebral ischemia. We hypothesized that neuronal injury and poor outcomes in patients undergoing CEA may be results of oxidative stress that disturbed function of antioxidant enzymes and contributed to the DNA damage in lymphocytes.

AB  - Phenolic groups of steroidal or nonsteroidal estrogens can redox cycle, leading to oxidative stress, where creation of reactive oxygen species are recognized as the main mechanism of their DNA damage properties. Dry olive (Olea europaea L.) leaf extract is known to contain bioactive and antioxidative components and to have an ability to modulate the effects of various oxidants in cells. The main goal of this study was to investigate antigenotoxic potential of a standardized dry olive leaf extract on DNA damage induced by 17β-estradiol and diethylstilbestrol in human whole blood cells in vitro, using comet assay. Our results indicated that both hormones showed a genotoxic effect at a concentration of 100 μM (P  lt  0.05, n = 6). Dry olive leaf extract was efficient in reducing number of cells with estrogen-induced DNA damage at tested concentrations (0.125, 0.5 and 1 mg/mL) (P  lt  0.05, n = 6) and under two experimental protocols, pre-treatment and post-treatment, exhibiting antigenotoxic properties. Analysis of antioxidant properties of the extract revealed moderate ABTS radical scavenging properties and reducing power. Overall, our results suggested that the protective potential of dry olive leaf extract could arise from the synergistic effect of its scavenging activity and enhancement of the cells' antioxidant capacity.

AB  - The health benefits of natural products have long been recognized. Consumption of dietary compounds such as supplements, provides an alternative source of natural products to those obtained from the diet. There is a growing concern regarding to possible side effects of using different food supplements simultaneously, since their possible interactions are less known. For the first time, we have tested genotoxic and antigenotoxic effects of Biochaga, in the cooperation to Dihydroquercetin. No genotoxic effect on whole blood cells was observed within individual treatment of Biochaga (250 μg/mL, 500 μg/mL and 1000 μg/mL) and Dihidroqercetin (100 μg/mL, 250 μg/mL and 500 μg/mL), nor in cooperation. Afterwards, antigenotoxic potency of both supplements (compounds) against oxidative hydrogen peroxide (H2 O2 ) induced DNA damage to whole blood cells (WBC) was assessed, using the comet assay. Biochaga and Dihydroquercetin displayed a strong potential to attenuate H2 O2-induced damage on DNA in cells at all tested concentrations, with a statistical significance (p<0.05), whereas Biochaga at the dose of 500 μg/mL in the cooperation with Dihydroquercetin 500 μg/mL was most prominent. Biochaga in cooperation with Dihydroquercetin is able to protect genomic material from oxidative damage induced by hydrogen peroxide in vitro.

AB  - The binding of thyroid hormones to specific nuclear receptors in target cells induces synthesis of enzymes associated with redox processes, leading to the formation of reactive oxygen species (ROS), which can cause damage of DNA molecule. Quercetin has already been shown to have protective effect against DNA damage, with its most pronounced feature being scavenging of free radicals. The aim of this study was to evaluate antigenotoxic potential of quercetin against thyroxine-induced DNA damage in human whole blood cells by using the comet assay. For that purpose, cells were exposed to 50 μM thyroxine and separately pre-treated or post treated with 500 μM of quercetin. Results showed that DNA damage was significantly reduced in cells pre-treated with this scavenger of free radicals. Obtained results indicate the ability of thyroxine to be a mediator of DNA damage and that quercetin displayed protective effect against thyroxine-induced genotoxicity.

AB  - Hypertension is one of the primary risk factors for heart disease and stroke, the leading causes of death worldwide. Numerous factors have been implicated in the pathophysiology of hypertension: endothelial dysfunction, arterial remodeling and vascular inflammation. Common to all these processes is increased bioavailability of reactive oxygen species in the vessels, heart, brain and kidneys. Oxidative stress and increased reactive oxygen species levels damage all macromolecules, with DNA being particularly susceptible to oxidative damage. The aim of this study was to determine whether there is a difference in the level of DNA damage between normotensive and hypertensive rats using the alkaline comet assay. Blood samples and cells suspension from liver and kidney from three male spontaneously hypertensive rats were obtained. Three normotensive male Wistar rats were used as a control. Increased level of DNA damage was detected in blood and both of the studied tissues of hypertensive rats compared to the control, where significant difference was present in the liver and kidney cell suspensions. These results indicate that untreated hypertension in rats leads to an increased DNA damage in all of the studied samples, detected by comet assay.

AB  - Objective. Prooxidants and antioxidants affect the oxidative balance at the intracellular level. Oxidative stress is a consequence of the overproduction of prooxidants and is caused by disturbances in the balance of oxidative reduction processes. Non-enzymatic low molecular weight antioxidants can be introduced into the body through food. Cordyceps sinensis (C. sinensis) is a medicinal fungus used in traditional Chinese medicine, with rich content of vitamins, various polysaccharides, and many nucleosides. The aim of this study is to evaluate the antioxidant capacity of the dietary supplement C. sinensis. Methods. The capacity of the hydroxyl radical scavenger activity, the total antioxidant activity of FRAP (Ferric Reducing Antioxidant Power) and the DPPH (2,2-diphenyl-1- picrylhydrazyl) scavenger activity were measured. Results. C. sinensis at the tested concentrations of 0.0078–2.00 mg/mL had a pronounced ability to remove hydroxyl radicals with IC50 of 0.5 mg/mL, while at concentrations (0.0078–10.00 mg / mL) it showed a moderate reducing ability. C sinensis showed no ability to remove DPPH radicals. Conclusion. C. sinensis effectively removes hydroxyl radicals, for which the body does not have adequate antioxidant protection, so we can include it in the group of free radical scavengers.

AB  - The health benefits of natural products have long been recognized. Consumption of dietary compounds such as supplements provides an alternative source of natural products to those obtained from the diet. There is a growing concern regarding the possible side effects of using different food supplements simultaneously, since their possible interactions are less known. For the first time, we have tested genotoxic and antigenotoxic effects of Biochaga, in combination with dihydroquercetin. No genotoxic effect on whole blood cells was observed within individual treatment of Biochaga (250 μg/mL, 500 μg/mL and 1000 μg/mL) and dihydroquercetin (100 μg/mL, 250 μg/mL and 500 μg/mL), nor in combination. Afterwards, antigenotoxic potency of both supplements against hydrogen peroxide- (H2O2-) induced DNA damage to whole blood cells (WBC) was assessed, using the comet assay. Biochaga and dihydroquercetin displayed a strong potential to attenuate H2O2-induced damage on DNA in cells at all tested concentrations, with a statistical significance (p < 0:05), whereas Biochaga at the dose of 500 μg/mL in combination with dihydroquercetin 500 μg/mL was most prominent. Biochaga in combination with dihydroquercetin is able to protect genomic material from oxidative damage induced by hydrogen peroxide in vitro.

AB  - Immune Assist (IA) is produced from extract of six species of medical mushrooms: Agaricus blazei - Cordyceps sinensis - Grifola frondosa - Ganoderma lucidum - Coriolus versicolor - Lentinula edodes. The genoprotective potential of IA was evaluated for the first time. Significant antigenotoxic effects were detected in human peripheral blood cells against H2O2 induced DNA damage, in the pretreatment and in the posttreatment. The most efficient concentration of IA in pretreatment was 500 μg/mL, while in posttreatment it was the concentration of 250 μg/mL. Kinetics of attenuation of H2O2 induced DNA damage in posttreatment with the optimal concentration of IA showed significant decrease in the number of damaged cells at all time periods (15–60 min), reaching the greatest reduction after 15 and 45 min. Remarkable ·OH scavenging properties and moderate reducing power, together with the modest DPPH scavenging activity, could be responsible for the great attenuation of DNA damage after 15 min of exposure to IA, while reduction of DNA damage after 45 min could be the result in additional stimulation of the cell’s repair machinery. Our results suggest that IA displayed antigenotoxic and antioxidant properties. A broader investigation of its profile in biological systems is needed.

AB  - Harmful effects of elevated levels of catecholamines are mediated by various mechanisms, including gene transcription and formation of oxidation products. The aim of this study was to see whether the molecular mechanisms underlying the damaging action of adrenaline on DNA are mediated by reactive oxygen species (ROS). To do that, we exposed human whole blood cells to 10 mu mol L-1 adrenaline or 50 mu mol L-1 H2O2 (used as positive control) that were separately pre-treated or post-treated with 500 mu mol L-1 of quercetin, a scavenger of free radicals. Quercetin significantly reduced DNA damage in both pre- and post-treatment protocols, which suggests that adrenaline mainly acts via the production of ROS. This mechanism is also supported by gradual lowering of adrenaline and H2O2-induced DNA damage 15, 30, 45, and 60 min after treatment. Our results clearly show that DNA repair mechanisms are rather effective against ROS-mediated DNA damage induced by adrenaline.

AB  - Manuka honey has been widely researched regarding its biological properties, in particular its antimicrobial and antioxidant capacities. We tested the genotoxic and genoprotective properties of Manuka honey, ranging from 25-1000 mu g/mL, by performing an in vitro comet assay after exposure to human whole blood. No genotoxic effect on whole blood cells was observed within the tested concentration range (p = 0.154). Then, the antigenotoxic potency of Manuka honey against oxidative DNA damage to whole blood cells was assessed. Prior to Manuka honey treatment a modest decrease of H2O2-induced DNA damage was detected in cells, with no statistical significance (p = 0.087). Post-treatment, Manuka honey displayed a stronger potential to attenuate damaged cells at all tested concentrations, with a statistical significant difference (p  lt  0.001), where concentrations of 25 and 100 mu g/mL were most efficient. Manuka honey exhibited a marked potential to protect DNA of whole blood cells from oxidative damage induced by hydrogen peroxide in vitro.

AB  - This study is aimed at analysing biochemical and genetic endpoints of toxic effects after administration of adrenaline. For this purpose, the study was carried out on Wistar rats and three doses of adrenaline were used: 0.75 mg/kg, 1.5 mg/kg, and 3 mg/kg body weight. To achieve these aims, we investigated the effects of adrenaline on catalase (CAT), Cu, Zn-superoxide dismutase (SOD), malondialdehyde (MDA), nitrite (NO2-), carbonyl groups (PCC), and nitrotyrosine (3-NT). Total activity of lactate dehydrogenase (LDH), its relative distribution (LDH1-LDH5) activity, level of acute phase proteins (APPs), and genotoxic effect were also evaluated. The obtained results revealed that all doses of adrenaline induced a significant rise in CAT activity, MDA level, PCC, NO2-, and 3-NT and a significant decrease in SOD activity compared to control. Adrenaline exerted an increase in total activity of LDH, LDH1, and LDH2 isoenzymes. Further study showed that adrenaline significantly decreased serum albumin level and albumin-globulin ratio, while the level of APPs (alpha(1) -acid glycoprotein and haptoglobulin) is increased. The micronucleus test revealed a genotoxic effect of adrenaline at higher concentrations (1.5 mg/kg and 3 mg/kg body weight) compared to untreated rats. It can be concluded that adrenaline exerts oxidative and nitrative stress in rats, increased damage to lipids and proteins, and damage of cardiomyocytes and cytogenetic damage. Obtained results may contribute to better understanding of the toxicity of adrenaline with aims to preventing its harmful effects.

AB  - Aim. Oxidative stress is a consequence of the increased production of free radicals that is caused by the disturbance in the balance of oxidation-reduction activity. Salvianolic acid B is a polyphenol compound, derived from the plant Salvia miltiorrhiza Bunge, which showed significant antioxidant properties. The aim of this study is the investigation of genotoxic potential of salvianolic acid B and evaluation of its antigenotoxic activity against the DNA damage induced by hydrogen peroxide in peripheral blood leukocytes in vitro, using the alkaline Comet assay. Materials and Methods. The evaluation of the ability of various concentrations of salvianolic acid B (12.5μM, 25μM and 50 μM) to reduce the number of cells with DNA damage caused by hydrogen peroxide as an oxidant was performed under two experimental protocols: pretreatment and cotreatment, in order to determine antigenotoxicity on preventive and intervention levels. Results. Results indicate that the salvianolic acid B did not exhibit a genotoxic effect after 30 minutes of incubation, in the tested concentrations. In the pretreatment, a concentration of 50 μM showed a significant decrease of the hydrogen peroxide induced DNA damage. Salvianolic acid B was more effective in reducing DNA damage in cotreatment, where concentrations of 25 μM and 50 μM demonstrated a significant abrogation of DNA damage. Protective effect of salvianolic acid B was dependent on the concentration. Conclusions. The results showed that salvianolic acid B has pronounced antigenotoxic effect on the intervention level, which makes it a potential agent in treatment of diseases in which oxidative DNA damage plays an important role.

AB  - The CaNa(2)EDTA chelation therapy is often practiced with antioxidant supplementation. Dry olive leaf extract (DOLE) is natural product with antioxidant and DNA protective properties. The effects of DOLE on the levels of DNA damage were investigated ex vivo in peripheral blood lymphocytes (PBLs) of 19 workers occupationally exposed to lead (Pb), before and after CaNa(2)EDTA chelation therapy. POLE demonstrated pronounced radical scavenging activity in concentrations >= 1 mg/mL, and showed no genotoxicity per se, in concentrations 0.125-1 mg/mL. The level of DNA damage in PBLs of workers before chelation therapy was elevated (24.21 +/- 14.26) compared to controls (6.0 +/- 3.37). The incubation of PBLs before chelation therapy with selected concentration of DOLE lead to a severe increase of DNA damage (64.03 +/- 20.96), exhibiting prooxidant rather than antioxidant effect. After the five-day CaNa2EDTA chelation regimen, DNA damage in PBLs of workers decreased (8.26 +/- 4.62) significantly compared to baseline. Treatment of PBLs with DOLE after chelation, again produced high level of damage (41.82 +/- 23.17) and the acute prooxidant effects of DOLE remained, but, DNA damage was less severe than before chelation. The DOLE exhibits prooxidant effect in presence of Pb in lymphocytes of exposed workers, and its effect is less pronounced following the removal of Pb after standard chelation therapy.

AB  - The ability of Agaricus blazei mushroom in its dried and powdered mycelial form was evaluated for its antigenotoxic properties for the first time. Antigenotoxic effects in human peripheral blood cells against H2O2-induced DNA damage were examined in pretreatment and posttreatment protocol by comet assay. The results showed better antigenotoxic properties of Agaricus blazei on the interventional level, respectively, after treatment. Agaricus blazei in concentration of 250 mu g/mL after treatment was most efficient in regard to its action against DNA damage. The evaluation of repair kinetics showed decrease in H2O2 induced DNA damage 15min after the application of A. blazei, reaching the maximum potency after 30 min. Analysis of antioxidant properties of Agaricus blazei revealed strong center dot OH scavenging properties and moderate reducing power, while its DPPH scavenging ability was weak. In regard to our findings, we can conclude that our preliminary results demonstrated antigenotoxic properties of Agaricus blazei and its strong center dot OH scavenging ability. Mechanisms underlying its properties should be further evaluated in in vivo studies.

AB  - Ascorbic acid (AA) is a standard antioxidant and its radical scavenging properties also appear to be responsible for its antigenotoxic properties. Nanoparticle-mediated delivery of antioxidant compounds is intended to increase their bioavailability while maintaining their effectiveness.  Colloids consisting of the 45-Å TiO2 nanoparticles (NPs) with anatase crystal structure were prepared by acidic hydrolysis of TiCl4. The synthesized TiO2 NPs were characterized using transmission electron microscopy and X-ray diffraction analysis. The charge transfer (CT) complex formation between surface Ti atoms and AA is indicated by immediate appearance of red color.  The aim of this study was to compare, for the first time, the antioxidant and antigenotoxic effects of AA attached to the surface of TiO2 NPs with free AA in a wide concentration range. For evaluation of antigenotoxic properties whole blood cells were first treated with 50 μM H2O2 to induce DNA damage, and then exposed to 3 different concentrations of free AA (1.3×10-2, 2.6×10-2, and 3.9×10-2 M) and the same concentrations of AA attached to TiO2 NPs (0.05, 0.1, and 0.15 M) for 30 min at 37 0C. The level of DNA damage was evaluated by comet assay method. For evaluation of antioxidant properties, total antioxidant capacity (TAC), total antioxidative status (TAS) and prooxidative-antioxidative balance (PAB) were determined in human serum pool during 2 and 24 h incubation at 37 °C, without and with terc-buthyl-hydroperoxide (TBH) as exogenously added oxidant. As expected, the results of DNA damage showed that the increase of AA concentration leads to a reduction of DNA damage. The similar concentration dependence was observed for surface-modified TiO2 NPs with AA. So, no significant differences between the antigenotoxic properties of free AA and AA attached to the TiO2 NPs were noticed, but only the highest concentrations showed significant effect in both experimental treatments. Regarding short-term oxidative balance in biological material (serum), during 2h, by measuring the TAC we have showed that the complex NP and AA, so as ascorbic acid showed a significant increase in TAC capacity, compared to native serum. This increase of antioxidative capacity couldn’t be abrogated even with a powerful oxidant, terc-buthylhydroperoxide presence (TBH). After 24h hour incubation the TAC level in both samples decreased towards the baseline level. About the TOS, which measures all oxidative components in plasma such as hydrogen-peroxide and lipid hydroperoxide, the complex of NP and AA versus AA alone showed inconsistent results. Prooxidative-antioxidative balance (PAB) measuring equilibrium between oxidants and antioxidants remains low, almost imponderable after 2h and after 24h serum incubation with the two substances. To summarize, we suggest that surface-modified TiO2 NPs with AA and/or similar compounds can be used to improve their bioavailability while maintaining its beneficial activities.

For evaluation of antigenotoxic properties whole blood cells were first treated with 50 μM H2O2 to induce DNA damage, and then exposed to 3 different concentrations of free AA (1.3×10-2, 2.6×10-2, and 3.9×10-2 M) and the same concentrations of AA attached to TiO2 NPs (0.05, 0.1, and 0.15 M) for 30 min at 37 0C. The level of DNA damage was evaluated by comet assay method. For evaluation of antioxidant properties, total antioxidant capacity (TAC), total antioxidative status (TAS) and prooxidative-antioxidative balance (PAB) were determined in human serum pool during 2 and 24 h incubation at 37 °C, without and with terc-buthyl-hydroperoxide (TBH) as exogenously added oxidant. As expected, the results of DNA damage showed that the increase of AA concentration leads to a reduction of DNA damage. The similar concentration dependence was observed for surface-modified TiO2 NPs with AA. So, no significant differences between the antigenotoxic properties of free AA and AA attached to the TiO2 NPs were noticed, but only the highest concentrations showed significant effect in both experimental treatments. Regarding short-term oxidative balance in biological material (serum), during 2h, by measuring the TAC we have showed that the complex NP and AA, so as ascorbic acid showed a significant increase in TAC capacity, compared to native serum. This increase of antioxidative capacity couldn’t be abrogated even with a powerful oxidant, terc-buthylhydroperoxide presence (TBH). After 24h hour incubation the TAC level in both samples decreased towards the baseline level. About the TOS, which measures all oxidative components in plasma such as hydrogen-peroxide and lipid hydroperoxide, the complex of NP and AA versus AA alone showed inconsistent results. Prooxidative-antioxidative balance (PAB) measuring equilibrium between oxidants and antioxidants remains low, almost imponderable after 2h and after 24h serum incubation with the two substances. To summarize, we suggest that surface-modified TiO2 NPs with AA and/or similar compounds can be used to improve their bioavailability while maintaining its beneficial activities.",

AB  - The CaNa2EDTA chelation is a standard therapy for lead (Pb) intoxication in occupationally exposed workers. Application of antioxidant nutrients through exogenous supplementation is often practiced with the chelation therapy, although their synergistic effect in reduction of Pb-induced oxidative damage has not been investigated conclusively. Dry olive Leaf extract (DOLE) is polyphenol rich natural antioxidant. The effects of DOLE on the levels of DNA damage were investigated ex vivo in peripheral blood lymphocytes (PBLs) of 19 male workers occupationally exposed to Pb, before and after application of five day CaNa2EDTA chelation therapy. Comet assay was used to assess levels of DNA damage. While the level of DNA damage in PBLs of workers before chelation were moderately increased (24.21±14.26) compared to controls (6.0±3.37), the incubation of the same samples with 1mg/mL DOLE for 30 min at 370C lead to a severe increase in DNA damage levels (64.03±20.96). After the exposure of workers to a five day CaNa2EDTA chelation regimen, the experiment was repeated. Following chelation, the level of DNA damage in PBLs of workers was decreased (8.26±4.62) significantly compared to the baseline value and was then similar to the control level. When the PBLs after chelation were treated with 1mg/mL DOLE for 30 min, high level of damage was obtained (41.82±23.17). The antigenotoxic effects of five day CaNa2EDTA chelation were demonstrated in PBLs of Pb exposed workers. On the contrary, the applications of DOLE lead to an increase of oxidative DNA damage after 30 min incubation, exhibiting prooxidant rather than antioxidant effect. After CaNa2EDTA treatment, the acute prooxidant effects of DOLE remained following the incubation, but, the oxidative DNA damage was less severe compared to the same experiment with DOLE before the chelation, probably as a result of partial removal of Pb from cells by chelation therapy. Prooxidant nature of DOLE could be a result of Pb-mediated hydroxyl radical formation, where heavy metals serve as catalysts for the reactions which oxidize DOLE and reduce oxygen. Removal of Pb by complexation with CaNa2EDTA seems to significantly depress these oxidative events. However, this mechanism remains to be explored on molecular level. It could be concluded that the DOLE exhibits prooxidant effects in presence of Pb in lymphocytes of exposed workers, and its effect is less pronounced following the removal of Pb after standard chelation therapy.

AB  - The essential oils of genus Seseli are known for their beneficial biological activities and could present novel targets in the development of safe and effective preparations of plant products. The objective was to test the essential oils of different parts of Seseli rigidum from two natural habitats for potential genotoxic and antigenotoxic activities against H2O2-induced DNA damage in human whole blood cells in vitro, by the comet assay. The essential oil analysis showed a high falcarinol content in oil from the root, while oils of the fruit and aerial parts contained a-pinene as the main compound. Genotoxicity was not detected at any of the concentrations of the essential oils from the three parts of the plant from localities I and II. Although the antioxidant activity (established by the FRAP and DPPH tests) of the investigated oils was low, all oils demonstrated a strong antigenotoxic effect against H2O2-induced damage post-treatment, when the oils were applied after the oxidant. Based on the lack of pretreatment activity and the post-treatment reduction in DNA damage, the antigenotoxic effect of S. rigidum essential oils was probably based on the stimulation of DNA repair mechanisms. Environmental conditions did not affect the antigenotoxic properties of the oils. In conclusion, our results revealed the antigenotoxic properties of S. rigidum essential oils and appropriate and safe doses with beneficial effects under the described conditions.

AB  - Context Cordyceps sinensis (C sinensis) is a well-known, traditional, Chinese medicinal mushroom, valued for its beneficial properties for human health. C sinensis has been reported to have immunomodulatory, anticancer, antiaging, antioxidant and anti-inflammatory activity. Despite potential medicinal benefits, no previously published reports are available about the genotoxicity or antigenotoxicity of C sinensis, as detected by comet assay. Objective The objective of the study was to evaluate both the genotoxic and antigenotoxic potential of an extract of C sinensis (CS extract) in human peripheral blood cells. Design The research team designed a pilot study. Setting The study was conducted at the Center for Biological Research, University of Belgrade, in Belgrade, Serbia. Participants Participants were 6 healthy individuals (2 males and 4 females), between the ages of 20 and 45 y, recruited on a voluntary basis, who provided heparinized, peripheral blood samples. Intervention Four concentrations of the CS extract125 mu g/mL, 250 mu g/mL, 500 mu g/mL, and 1000 mu g/mL-were used in the treatment of tested blood cells from the blood samples. Three independent procedures were performed: (1) a genotoxicity assessment, (2) an antigenotoxicity assessment for pretreatment of human cells with the CS extract prior to their exposure to hydrogen peroxide (H2O2) (ie, an evaluation of the benefits of the CS extract as a preventive agent); and (3) posttreatment of human cells with the CS extract after their exposure to H2O2 (ie, an evaluation of the benefits of the CS extract as an interventional agent). Outcome Measures Cells were graded by eye inspection into 5 classes, depending on the extent of DNA damage, representing: (1) class A-undamaged cells with no tail ( lt 5% damaged DNA); (2) class B-low-level damage (5%-20%); (3) class C-medium-level damage (20%-40%); (4) class D-high-level damage (40%-95%), and (5) class E-total destruction (>95%). Results The CS extract proved to be nongenotoxic because no induced DNA damage was detected at all tested concentrations. For the antigenotoxicity assessment of the pretreatment with the CS extract, only the 1000-mu g/mL concentration showed a significant decrease in the number of cells exhibiting H2O2-induced DNA damage. For the posttreatment, the CS extract exhibited antigenotoxic potential by attenuating H2O2-induced DNA damage at all concentrations tested. The evaluation of repair kinetics showed a decrease in DNA-damaged cells 15 min after the application of the CS extract, reaching a maximum potency after 45 min. Conclusions The results indicated that C sinensis can be used as a postapplicative agent that counteracts the effect of oxidative stress. The resulting reduction in DNA damage might be related to its scavenging properties and stimulation of DNA repair.

AB  - The effects of co-administration of dry olive leaf extract (DOLE) with standard methotrexate (MTX) therapy on the parameters of cell damage and inflammation in patients with early and long-term rheumatoid arthritis (RA) were evaluated at baseline, 3 and 6weeks. Patients were assigned to groups: the early phase RA group on MTX monotherapy (E MTX), and the two RA groups that received co-treatment with DOLE and MTX: early (E MTX+DOLE) and long-term phase patients (L-t MTX+ DOLE). Baseline values indicated increased parameters of cell damage and disruption of redox balance in all groups. After three weeks the E MTX+DOLE group maintained high catalase activity, exhibited decrease of lipid peroxidation and protein damage indicatorsthiols and nitrites, while levels of DNA damage and pro-inflammatory interleukin-6 were significantly reduced. In E MTX group catalase activity remained unaltered while significant lipid peroxidation and DNA damage reductions were seen only after six weeks. L-t MTX+DOLE group showed only modest alterations of cell damage parameters during six weeks. Combined administration of DOLE with MTX contributes to faster reduction of cell damage, restores oxidative balance and improves interleukin-6 suppression during high disease activity in early phase RA, but not in long term patients.
