AB  - TiO2 prolatenanospheroids (PNSs) may be photosensitizers (PSs), which act by catalyzation of hydroxyl radical (∙OH) formation upon light illumination. ∙OH might, in turn, contribute to killing of cancer cells. On the other hand, there is great concern about toxicity in the dark of TiO2 nanoparticles in general. In this work, we have investigated the biocompatibility of TiO2 PNSs of the anatase crystal form (length between 100 and 300 nm and width 50 nm) in the dark with immune cells and light-induced cytotoxicity on several cancer cell lines. The effects of the treatment of different cell lines with several concentrations of TiO2 PNSs suspensions showed the specifics of cells’ viability and the intracellular localization. The results of in vitro studies obtained by cytotoxicity assays adjusted to individual cell lines’ metabolism point towards the biocompatibility of TiO2 PNSs at low and moderate concentrations in the dark, which neither kill the cells, nor induce activation of the immune system cells. Laser scanning confocal microscopy revealed that PNSs are taken up by cells, and insight into the intracellular distribution was obtained in this study.

AB  - Introduction The oxidative stress contributes to all three phases of carcinogenesis and represents a concomitant condition in renal cell carcinoma (RCC). RCC is the most common type of neoplasm of the kidney, and despite numerous studies the set of predictive and prognostic markers of survival are still unknown. The aim of our study was to examine the relation between antioxidant (AO) status and overall survival (OS) in RCC patients.  Material and methods Our study included 95 patients with RCC, who underwent radical nephrectomy. We analysed the prognostic role of antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase, glutathione reductase, glutathione, and malondialde-hyde) and other clinicopathological factors (size, grade, stage, and histological subtype) on the OS of RCC patients.  Results The 5-year OS was 54.6%. The survival analysis related to AO parameters showed no significant difference in survival of RCC patients. The concentration of malondialdehyde, an indicator of lipid peroxidation, also had no significant effect on the survival rate of RCC pa-tients. Univariate and multivariate analysis confirmed the significance of clinicopathological parameters (size, p < 0.001; Fuhrman grade, p = 0.001, and stage, p < 0.001) for patients’ survival.  Conclusions In our cohort of patients, different antioxidant parameters were not found to be predictors for OS of patients with RCC, who underwent radical nephrectomy.

AB  - This study aimed to investigate the effects of chronic restraint stress (CRS) on the protein levels of dopamine-β-hydroxylase (DBH), noradrenaline transporter (NET), vesicular monoamine transporter 2 (VMAT2) and brain-derived neurotrophic factor (BDNF), as well as the concentration of noradrenaline (NA) in the rat hippocampus. The investigated parameters were quantified by Western blot analyses and ELISA kits. We found that CRS increased the protein levels of DBH by 30 %, VMAT2 by 11 %, BDNF by 11 % and the concentration of NA by 104 %, but decreased the protein levels of NET by 16 % in the hippocampus of chronically stressed rats. The molecular mechanisms by which CRS increased the hippocampal NA level are an important adaptive phenomenon of the noradrenergic system in the stress condition. © 2020 Charles University.

AB  - The effects of twelve weeks of supplementation with fullerene C60 olive/coconut oil solution on a broad spectrum of parameters in rats were examined. The tissue bioaccumulation of C60 was shown to be tissue-specific, with the liver, heart, and adrenal glands being the organs of the greatest, and the kidney, brain, and spleen being the organs of the smallest accumulation. C60 did not change aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase serum activities level, nor the damage of liver cells DNA. There were no effects of fullerene on prooxidant-antioxidant balance in the liver, kidney, spleen, heart, and brain, nor any visible harmful effects on the liver, heart, aorta, spleen, kidney, and small intestine histology. Fullerene changed the gut microbiota structure towards the bacteria that ameliorate lipid homeostasis, causing a serum triglycerides concentration decrease. However, C60 significantly increased the insulin resistance, serum ascorbate oxidation, and brain malondialdehyde and advanced oxidation protein products level. The deteriorative effects of C60 on the brain and serum could be attributed to the specific physicochemical composition of these tissues, potentiating the C60 aggregation or biotransformation as the key element of its pro-oxidative action.

AB  - This study examined the effects of lithium on gene expression and activity of the antioxidant enzymes copper zinc superoxide dismutase (SOD1), manganese superoxide dismutase (SOD2), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR) in the hippocampus of chronically stressed rats. In addition, we examined the effects of lithium on anxiety behaviors, hippocampal concentrations of dopamine (DA) and malondialdehyde (MDA), protein levels of brain-derived neurotrophic factor (BDNF), tyrosine hydroxylase (TH), dopamine transporter (DAT), and catechol-O-methyltransferase (COMT), as well as activity of monoamine oxidase (MAO) in chronically stressed rats. The investigated parameters were quantified by real-time RT-PCR, Western blot analyses, and assays of enzyme activities. We found that lithium did not change gene expression of SOD1, CAT, GPx, and GR but decreased gene expression of SOD2 in chronically stressed rats. A very important result in this study was that lithium treatment decreased the enzyme activities of SOD1 and SOD2 but increased the enzyme activities of GPx and GR in stress condition, which indicates the control of redox balance. The reduced concentration of MDA confirms this. In addition, we found that lithium treatment decreased high protein levels of BDNF and DAT in chronically stressed rats to the level found in unstressed animals. Also, lithium treatment increased the expression of TH but decreased the enzyme activity of MAO B, which contributed to the increase of hippocampal concentration of DA in chronically stressed rats to the level of unstressed animals. Finally, lithium treatment in animals exposed to chronic stress increased the time spent in open arms. Lithium-induced modulation of hippocampal antioxidant status and attenuation of oxidative stress stabilized behavior in animals with high anxiety index. In addition, reduced oxidative stress was followed by the changes of both turnover of DA and levels of BDNF protein in chronically stressed rats treated with lithium. These findings may be important in preclinical research of the effects of lithium on oxidative stress level in pathological conditions.

AB  - We previously found that compared to patients with benign uterine diseases (polyps, myomas), patients with premalignant (hyperplasia simplex and complex) and malignant (adenocarcinoma) lesions had enhanced lipid peroxidation and altered uterine antioxidant enzyme (AOE) activities. To further elucidate the mechanism of the observed changes, we examined protein and mRNA levels of copper-zinc superoxide dismutase (CuZnSOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), and transcription factor Nrf2. We also examined correlations of AOE expression with AOE activity, lipid hydroperoxides (LOOH) level, and level of Nrf2. Our results showed decreased CuZnSOD, CAT, and Nrf2 levels, and increased GPx and GR levels in hyperplasias, while in patients with adenocarcinoma, the level of CAT was decreased and GR was increased, compared to benign groups. Similar changes in mRNA levels were also detected, indicating predominantly translational control of the AOE expression. The positive correlation of enzyme expression/activity was recorded for CuZnSOD, GPx, and GR, but only among groups with benign diseases. Only GR and GPx expressions were positively correlated with LOOH. Nrf2 protein was positively correlated with mRNA levels of CuZnSOD and GR. Observed results indicate involvement of diverse redox mechanisms in etiopathogenesis of different gynecological diseases, and may improve redox-based approaches in current clinical practice.

Our results showed decreased CuZnSOD, CAT, and Nrf2 levels, and increased GPx and GR levels in hyperplasias, while in patients with adenocarcinoma, the level of CAT was decreased and GR was increased, compared to benign groups. Similar changes in mRNA levels were also detected, indicating predominantly translational control of the AOE expression. The positive correlation of enzyme expression/activity was recorded for CuZnSOD, GPx, and GR, but only among groups with benign diseases. Only GR and GPx expressions were positively correlated with LOOH. Nrf2 protein was positively correlated with mRNA levels of CuZnSOD and GR. Observed results indicate involvement of diverse redox mechanisms in etiopathogenesis of different gynecological diseases, and may improve redox-based approaches in current clinical practice.",

AB  - Introduction/Objective We determined the impact of antioxidant supplementation by GE132® on sports performance, oxidative stress markers, and muscle enzymes activities in professional female basketball players. Methods Repetitive strength, explosive power, anaerobic endurance, and agility performance were measured before/after the 45-day supplementation period. The FORT (Free Oxygen Radicals Test) and FORD analysis (Free Oxygen Radical Defense) were assessed before/after basketball specific exercise bout, at the beginning/end of observational period. The grade of muscle damage was evaluated by aspartate aminotransferase (AST), creatine kinase (CK) and lactate dehydrogenase (LDH). Results After supplementation period, significant difference was not recorded regarding the basic motor skills tests. Basketball specific exercise bout induced significant increase in FORT (p < 0.05) only at the beginning of supplementation period. Both FORT and FORD significantly decreased over the observational period (p < 0.001, p < 0.01, respectively). CK and LDH were remarkably lower at the end of observational period (p < 0.05), compared to the baseline. Conclusion Exogenous supplementation with protective nutraceuticals such as those found in GE132®, could reduce acute/chronic oxidative stress and muscle damage, but had no effect on sport performance in basketball players. © 2019, Serbia Medical Society.

AB  - The effects of chronic restraint stress (CRS, 2 h during 14 days) on gene expression of tyrosine hydroxylase (TH), catechol-O-methyltransferase (COMT), and glutathione peroxidase (GPx) were studied in the rat hippocampus. Changes in the dopamine (DA) concentration and activities of monoamine oxidases (MAO A and MAO B) and GPx in this cerebral structure of chronically stressed rats were also examined. The investigated parameters were quantified using real-time RT-PCR, Western blot analyses, and assay of enzymatic activity. We found that CRS decreased the TH protein level and DA concentration, which probably confirms the statement that de novo synthesis of DA is suppressed under stress conditions. The increased activities of MAO B, as well as the increased level of COMT protein, are believed to be related to intensified DA catabolism conditions. Also, a decreased activity of GPx in the hippocampus of chronically stressed animals was found. The increased enzymatic activity of MAO B negatively correlated with the reduced activity of GPx under the above-mentioned stress conditions. These events in the hippocampus of chronically stressed animals could synergistically cause oxidative damage to the mitochondria. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

AB  - We examined the effects of daily exercise on the gene expression of catecholamine biosynthetic enzymes (tyrosine hydroxylase (TH), dopamine-β-hydroxylase (DBH), and phenyl
ethanolamine N-methyltransferase (PNMT)), vesicular monoamine transporter 2 (VMAT 2),
antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx)), concentrations of catecholamines (noradrenaline (NA) and adrenaline (A))
and malondialdehyde (MDA), activities of monoamine oxidase (MAO), and antioxidant
enzymes in the spleen of chronically psychosocially stressed rats. Exposure of chronically
stressed rats to exercise increased the levels of PNMT protein by 19%, VMAT 2 mRNA by
100%, NA by 160%, and A by 140%; decreased/unchanged MAO enzyme activity; returned
concentrations of MDA to control level; and increased CAT and GPx mRNA levels (50%
and 150%, respectively). Exercise induced the accumulation of the catecholamines and a
decrease of stress-induced oxidative stress in the spleen, which may significantly affect the
immune-neuroendocrine interactions in stress conditions. Also, exercise induced the catecholaminergic system and antioxidant defense to become more ready to a novel stressor,
which indicates that exercise may induce potentially positive physiological adaptations.
Our combined model of chronic social isolation and long-term daily treadmill running in
rats may be a good animal model in the research of therapeutic role of exercise in human
disease caused by chronic stress.

AB  - Screens of antioxidant activity (AA) of various natural products have been a focus of the research community worldwide. This work aimed to differentiate selected samples of Merlot wines originated from Montenegro, with regard to phenolic profile and antioxidant capacity studied by survival rate, total sulfhydryl groups and activities of glutathione peroxidase (GPx), glutathione reductase and catalase in H2O2–stressed Saccharomyces cerevisiae cells. In this study, DPPH assay was also performed. Higher total phenolic content leads to an enhanced AA under both conditions. The same trend was observed for catechin and gallic acid, the most abundant phenolics in the examined wine samples. Finally, the findings of an Artificial Neural Network (ANN) model were in a good agreement (r2 = 0.978) with the experimental data. All tested samples exhibited a protective effect in H2O2–stressed yeast cells. Pre-treatment with examined wines increased survival in H2O2–stressed cells and shifted antioxidative defense towards GPx–mediated defense. Finally, sensitivity analysis of obtained ANN model highlights the complexity of the impact that variations in the concentrations of specific phenolic components have on the antioxidant defense system.

AB  - This study examined the effects of chronic restraint stress (CRS) on gene expression of tyrosine hydroxylase (TH), dopamine-beta-hydroxylase (DBH), dopamine transporter (DAT), noradrenaline transporter (NET), vesicular monoamine transporter 2 (VMAT2), catechol-O-methyltransferase (COMT) and antioxidant enzymes such as superoxide dismutase (SOD1 and SOD2), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR), as well as concentrations of dopamine (DA) and noradrenaline (NA), activities of monoamine oxidase (MAO A and MAOB) and activities of antioxidant enzymes (SOD1, SOD2, CAT, GPx and GR) in the rat prefrontal cortex (PFC). We found that CRS decreases gene expression of TH and DBH and concentrations of DA, which probably confirms the decrease of de novo synthesis of catecholamine. CRS increased protein levels of NET and VMAT2, which was followed by increased NA concentration. The increased activity of MAO A and MAO B, as well as increased protein levels of COMT probably indicate increased catecholamine degradation, which was followed by increased activity of SOD1, SOD2 and CAT, as well as decreased activity of GPx under stress conditions. Our findings confirm the increased prefrontal noradrenergic turnover in animals exposed to CRS. The molecular mechanisms by which CRS changes catecholaminergic turnover and the antioxidant defense system in the PFC may be very important for research on numerous psychiatric diseases caused by chronic stress.

AB  - Purpose: Indications of kidney cancer outcome in lower-income countries are based on an incidence/mortality ratio due to lack of survival information. This study was conducted to provide outcome data in Serbian patients with renal cell carcinoma (RCC) and to identify prognostic factors that could affect their overall survival (OS). Methods: This retrospective study included 185 patients who underwent nephrectomy. We assessed certain clinicopathological data including age, gender, tumor size, grade, stage and histological subtypes for their possible impact on OS. Results: The 5-year OS was 63.2%. Significant association was found between OS and age (log-rank 12.455, p=0.006), tumor size (log-rank 26.425, p=0.000), grade (log-rank 13.249, p=0.000) and stage (log-rank 43.235, p=0.000). Univariate analysis indicated size (p=0.000), grade (p=0.001) and stage (p=0.000) as prognostic factors for OS. In multivariate analysis, grade (p=0.014) and stage (p=0.000) remained significant predictors of OS. Conclusion: Tumor grade and stage were identified as independent prognostic factors of OS survival in Serbian patients with RCC.

AB  - This study examined the effects of chronic restraint stress (CRS: 2 hours x 14 days) on gene expression of three antioxidant enzymes, copper, zinc superoxide dismutase (SOD 1), manganese superoxide dismutase (SOD 2) and catalase (CAT) in the rat hippocampus. Also, we examined changes in the activities of SOD 1, SOD 2 and CAT in the hippocampus of chronically stressed rats. Investigated parameters were quantified by using real-time RT-PCR, Western blot analysis and assay of enzymatic activity. We found that CRS did not change mRNA and protein levels of SOD 1 and CAT, but increased mRNA and protein levels of SOD 2. However, CRS treatment increased the enzyme activities of SOD 1, SOD 2 and CAT. Our findings indicate that the increased activity of antioxidant enzymes (SOD 1, SOD 2 and CAT) in the hippocampus may be an important adaptive phenomenon of the antioxidant defense system in chronically stressed rats.

AB  - Celiac disease (CD) is an autoimmune disorder provoked by the wheat gluten and related proteins from other grains. The only treatment for the patients is a lifelong gluten free diet (GFD). Oxidative stress has been implicated in the pathogenesis of CD. The aim of this study was to examine the modulation of the biochemical response to oxidative stress in children affected by CD. The study involved peripheral blood samples and small intestinal biopsies from 69 children diagnosed with CD. According to the histological findings, patients were divided into following groups: Marsh 0: normal mucosa with no signs of inflammation (n=31); Marsh 1: mucosa was characterized by intraepithelial lymphocytosis (n=5); Marsh 2: intraepithelial lymphocytosis was accompanied by crypt hyperplasia (n=4); Marsh 3a: mucosa showed partial villous atrophy (n=20); Marsh 3b: subtotal villous atrophy was present (n=9). For the statistical purposes groups Marsh 1 and Marsh 2 were treated as one (Marsh 1+2, n=9). The activities and protein levels of copper, zinc superoxide dismutase (CuZnSOD) and manganese SOD (MnSOD), as well as the concentrations of lipid hydroperoxides (LOOH) were determined in intestinal biopsies, while in the peripheral blood, MnSOD activity was not measured, due to the methodological obstacles. CuZnSOD activity in the blood varied significantly between the analyzed groups. Marsh 3a and Marsh 3b had increased CuZnSOD activity comparing to the Marsh 0 (P < 0.05). LOOH concentration also varied significantly. LOOH level was higher in the blood of Marsh 3a (P < 0.001) and Marsh 3b (P < 0.05), than in Marsh 0. In the biopsy samples, MnSOD activity and LOOH concentration showed significant differences between the groups, while no significant difference was found for CuZnSOD activity. In comparison to Marsh 0, MnSOD activity was significantly elevated in Marsh 3a (P < 0.01). Significant increase in LOOH concentration was found in Marsh 3a (P < 0.001) and Marsh 3b (P < 0.01), comparing to Marsh 0. In addition, Marsh 3a group had higher LOOH concentration than Marsh 1+2. Relative MnSOD and CuZnSOD protein level in the peripheral blood and intestinal mucosa did not vary significantly between the analyzed groups. Positive correlations were found between the severity of mucosal lesion and CuZnSOD activity (P < 0.001), as well as LOOH concentration (P < 0.001) in the peripheral blood. Similar correlations were found also in intestinal mucosa: MnSOD: P < 0.05; CuZnSOD: P < 0.05; LOOH: P < 0.001. Our results show that oxidant/antioxidant balance is disturbed in CD patients with mucosal lesions. An increase in SOD activity as a consequence of oxidant pressure is not enough to maintain the normal level of free radicals, which leads to enhanced lipid peroxidation. These processes persist even in some patients on a long-term GFD.

AB  - Chronic stress induces over-activation and dysfunction of stress-activated systems, resulting in further brain damage and depressive-like behavior. Depression is a potentially life-threatening disorder that affects people and, therefore, it is one of the most important public health problems. This study examined the effects of chronic restraint stress (CRS: 2 hours × 14 days) on the anxiety-like and depression-like behaviors in rats, as well as on the possible changes in the concentrations of dopamine (DA) and noradrenaline (NA) in the prefrontal cortex and hippocampus. We observed a decrease in the number of entries into open arms and time spent in open arms during the elevated plus-maze test (anxiety-like behavior), as well as the increased immobility during the forced swimming test (depression-like behavior). In addition, we found that CRS increases concentration of NA and decreases concentration of DA in the prefrontal cortex and hippocampus. Also, we recorded a significant correlation between the animal behavior and levels of neurotransmitters in the prefrontal cortex and hippocampus in stress conditions provoked by CRS. The results presented here suggest that there is a relationship between the animal behavior and levels of neurotransmitters in the prefrontal cortex and hippocampus in stress conditions provoked by CRS, which may be important in the research of numerous psychiatric diseases caused by chronic stress. © RAD Conference Proceedings.

AB  - The study deals with manganese superoxide dismutase, copper, zinc superoxide dismutase, and catalase activities in brain cortex of Wistar rats exposed to acute stress (immobilization or cold for 2 h), chronic stress (long-term isolation or long-term forced swimming for 21 days), or to combined chronic/acute stress. We observed that i) single episodes of acute stress by immobilization increased activity of both superoxide dismutases; ii) both types of chronic stresses significantly elevated activities of all examined enzymes; iii) chronic social isolation was a much stronger stressor than physical stress by swimming; iv) in animals pre-exposed to chronic isolation, additional stress by immobilization or cold significantly decreased previously elevated activities of all enzymes, while after chronic swimming, acute immobilization lowered only catalase activity. The obtained results indicate that stress conditions most probably altered the cell redox equilibrium, thus influencing the antioxidant response in brain cortex. Further investigation of neuronal prooxidant/antioxidant cellular conditions is needed to improve the prevention and treatment of various stress induced diseases.

AB  - Endometrial tissue is under a strong influence of sex hormones. These hormones are considered as developmental factors of endometrial hyperplasia and endometrial cancer. We examined the influence of gonadotropins (follicle-stimulating and luteinizing hormone) and sex hormones (estradiol, progesterone) on oxidant/antioxidant parameters in blood and endometrial tissue of women with complex endometrial hyperplasia. In blood, superoxide dismutase activity was significantly higher in luteal phase and postmenopause compared to the follicular phase. A significant phase-related difference of glutathione peroxidase and glutathione reductase activity was recorded in the endometrium. Both enzymes had lower activity in luteal phase and postmenopause compared to the follicular phase. The linear regression analysis of individual hormonal variables against antioxidant parameters showed negative correlation between glutathione peroxidase activity and gonadotropin concentrations in the endometrium. The regression of hyperplastic to normal endometrium is the purpose of conservative treatment based on administration of progestogens or gonadotropin-releasing hormone analogues. Our findings indicate that gonadotropins influence the antioxidant enzymes activity in women with complex endometrial hyperplasia, which may affect disease development. Further studies are needed to clarify the molecular basis of hormone action on antioxidant system that may potentially initiate a development of treatments based onredox-dependentmechanism.

Further studies are needed to clarify the molecular basis of hormone action on antioxidant system that may potentially initiate a development of treatments based onredox-dependentmechanism.",

AB  - Renal cell carcinoma is the most common and the most lethal type of kidney cancer with the highest incidence in developed countries. At the moment of diagnosis, many patients already have developed metastases. Tobacco smoking, obesity, hypertension and occupational exposure are established risk factors. Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) are antioxidant enzymes (AOE) that have a key role in protecting from reactive oxygen species (ROS) produced in pathological processes. We examined the antioxidant capacity of tumour tissue in patients with clear cell type of renal cell carcinoma. The results showed a significant decrease of AOE activities in the tumour tissue compared to the normal kidney tissue, indicating that the tumour tissue is under permanent oxidative stress. Renal cell carcinoma is highly resistant to radiation therapy, which is also associated with free radical production. Since the tumour tissue has impaired AO capacity, the findings of this study may contribute to the improvement of the potential therapeutic treatments.

AB  - Apoptosis is an active energy-consuming mechanism of cell death, which may contribute to heart failure in patients with dilated cardiomyopathy. Dilated cardiomyopathy is a common clinical outcome of many prolonged cardiac insults, and therefore is considered as the most prevalent form of cardiomyopathy. Loss of heart mass is highly correlated with the heart failure and mortality, thus the purpose of this study was to define the apoptotic index in patients with dilated cardiomyopathy. Apoptosis was detected by the TUNEL method in 30 patients. Biopsies were obtained from the left ventricle, and at least three specimens were taken. TUNEL-positive cardiomyocytes were found in 26 of 30 cases (86.7 %) and the mean apoptotic index for the entire specimen series was 5.41 +/- 1.70 %. The analysis showed that patients with dilated cardiomyopathy had significantly higher apoptotic index (P LT 0.001) than healthy subjects. One subject (man, 41 years old) had a markedly elevated apoptotic index of 52.2 %. In the remaining subjects, the percentage of cardiomyocyte death ranged from 0 % to 15.5 %. The high percentage of apoptosis found in our study may be in accordance with the clinically manifested cardiac failure in patients with dilated cardiomyopathy since in most patients we recorded the left ventricular ejection fraction values below 30 %.

AB  - Cancer of the reproductive tract is an important cause of morbidity and mortality among women worldwide. In this study we evaluated the influence of diagnostic categories, age and reproductive factors on antioxidant enzymes and lipid hydroperoxides in the blood of gynaecological patients diagnosed with endometrial polyp, myoma, hyperplasia simplex, hyperplasia complex and endometrial adenocarcinoma. Multivariate regression analysis was used to assess the association of diagnosis, age, parity, abortions and abnormal uterine bleeding with the examined parameters. Diagnosis provided the best predictive model for superoxide dismutase, catalase and glutathione peroxidase activities, and also for the lipid hydroperoxide level. Abortions fitted the best predictive model for superoxide dismutase activity. A significant correlation was also found between the predictor variables themselves. This study showed that reproductive and other factors may be associated, at least partially, with antioxidant capacity and ability to defend against the oxidative damage in gynaecological patients with various diagnoses.

AB  - Uterine leiomyomas are benign soft-tissues tumors that arise from uterine smooth muscle tissue. Etiopathogenesis of leiomyomas is not well understood. We aimed to examine whether antioxidant enzyme activities and lipid hydroperoxides level in patients with leiomyoma are influenced by changes in sex hormones and gonadotropins (estradiol (E2), progesterone, FSH, and LH) during menstrual cycle and in postmenopause. The material consisted of blood and uterine tissue specimens. Hormone concentrations were determined and assays for superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase activities and lipid hydroperoxides concentration were performed. In blood of examined women, a significant difference in catalase, glutathione peroxidase and glutathione reductase activity was recorded among the phases. There was also a positive correlation between the estradiol/progesterone concentration and the catalase activity. Progesterone negatively correlated with lipid hydroperoxides level. In myoma tissue, we recorded a phase-related difference in lipid hydroperoxides level and activities of superoxide dismutase, glutathione peroxidase activities, and glutathione reductase. Negative correlation was observed between FSH and glutathione peroxidase. The results suggest that antioxidant status in patients with uterine leiomyoma is influenced by the changes in sex hormones during the menstrual cycle and in postmenopause, indicating a role of the observed relationship in the leiomyoma etiology.

AB  - Purpose Previously, we examined manganese superoxide dismutase (MnSOD), copper-zinc superoxide dismutase (CuZnSOD), and catalase (CAT) activities in rat brain irradiated with 2 or 3 Gy of gamma-rays. The results indicated that lower MnSOD activity and inducibility found in hippocampus might explain higher radiosensitivity of this brain region. Thus, in this study, we wanted to determine changes of MnSOD, CuZnSOD, and CAT activities after dose of 5 Gy and to find out if differences in MnSOD activity are caused by changes in its expression. Heads of 4-day-old female rats were irradiated with gamma-rays, using Co-60. Animals were sacrificed 1/24 h after exposure. Hippocampus and cortex tissues were prepared for enzyme activity measurements and Western blot analysis. One hour after exposure, gamma-rays significantly decreased MnSOD activity in both examined brain regions. Twenty-four hours later, MnSOD recovery showed dose and regional dependence. It was weaker at higher doses and in hippocampal region. MnSOD expression changed in the similar manner as MnSOD activity only at lower doses of gamma-rays. In both examined brain regions, gamma radiation significantly decreased CuZnSOD activity and did not change activity of CAT. Our results confirmed that MnSOD plays an important role in different regional radiosensitivity but also showed that depending on dose, radiation affects MnSOD level by utterly different mechanisms. Postradiation changes of CuZnSOD and CAT are not regionally specific and therefore, cannot account for the different radiosensitivity of the hippocampus and cortex.

AB  - Endometrial hyperplasia complex is gynecological disorder characterized by morphological irregularities of glands shape and size. Antioxidant enzymes (AOE), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR), have an essential role in preventing oxidative damage in cell caused by reactive oxygen species (ROS). In this study, we examined the AO status in hyperplastic tissue of patients in menstrual cycle (follicular and luteal phase) and in postmenopause, as well as the relationship between sex hormones and AO parameters. The phase-related activity of GPx and GR in examined patients was significantly different than in healthy women. A significant negative correlation between FSH/LH level and GPx activiy was observed. Endometrial hyperplasias are considered as precancerous lesions and are treated either conservatively or surgicaly, and also by radiation therapy. Since the effects of these therapies are associated with AO and hormonal changes, our results may contribute to the prediction of potential therapeutic efficacy and to selection of the most effective treatment for hyperplasia complex.

AB  - Cancer of the reproductive tract is an important source of morbidity and mortality among women worldwide. Factors affecting endometrial cancer and endometrial hyperplasia are known to be similar. Endometrial hyperplasia is abnormal proliferation of the glands and the stroma resulting in architectural and cytological modifications. Due to hormonal changes, this condition is most common among women who are nearing the menopause or have reached the menopause. Antioxidant system has a role in preventing cancer initiation and promotion. Since the carcinogenesis occurs in several stages, it is likely that the antioxidant defense depends on the type of cell and tissue. The objective of this study was to investigate whether antioxidant enzymes activities and lipid hydroperoxides concentration in patients with endometrial hyperplasia are influenced by the changes in sex hormones level (estradiol, progesterone, FSH, and LH) during the menstrual cycle and in postmenopause. The material we used consisted of blood and endometrial tissue specimens of women diagnosed with endometrial hyperplasia simplex. Patients were divided in groups depending on the phase of the menstrual cycle: follicular phase, luteal phase and postmenopause. The activities of antioxidant enzymes and the lipid hydroperoxides level were compared among the phases to test the differences and a linear regression model was used to evaluate the associations between hormone levels and antioxidant/oxidant variables. In the blood of examined patients, we observed a phase-related changes of LOOH concentrations. Significant negative correlation between FSH concentration and GR activity (r= -0.42, p<0.05) and significant positive correlation between LH and LOOH concentrations (r= 0.038, p<0.05) was found. In hyperplasia simplex tissue we recorded significant phase-related changes of LOOH level as well as of AO enzyme activities. SOD and CAT had similar activity pattern, which was higher in luteal phase and in postmenopause, compared to follicular phase (p<0.05). GPx and GR activities did not show any statistical difference. Also, negative correlation between progesterone and GR activity (r=-0.036, p<0.05) was observed. Hormonal influence on AO system is of importance in gynecological diseases etiology since they may promote cell proliferation but are also used in conservative therapy, especially for hyperplasia simplex. However, the role of ROS production as a risk factor for endometrial hyperplasia still needs to be clarified as well as the role of AO status in response to gonadotropins and sex steroids.
