Abstract Lake Van fish (Alburnus tarichi Guldenstadt 1814) is the only fish that can adapt to the extreme conditions (pH 9.8 salinity 0.2% and alkalinity 151.2 meq/L) of Lake Van. In this study, it was aimed to determine the cytotoxic and genotoxic effects of chlorpyrifos (CPF) on Lake Van fish primary gill cell culture. Gill epithelium from Lake Van fish was isolated enzymatically and grown in primary culture on Leibovitz’s L-15 medium. After different doses (0.01, 0.1, 1, and 10 μM) of CPF were applied to the gill cells, the total oxidant status (TOS), total antioxidant status (TAS), malondialdehyde (MDA), and DNA damage levels (8-hydroxyguanine (8-OHdG)) were examined at the end of 24 and 48 h. It was determined that the TOS, MDA, and 8-OHdG levels increased in the cells exposed to high doses (1 and 10 μM) of CPF and the TAS was decreased (P < 0.05). It was revealed from this study that CPF administered at a dose higher than 1 μM can cause oxidative stress and DNA damage in the primary gill cell culture of Lake Van fish. In addition, the findings showed that Lake Van fish primary gill cell culture was useful in determining the effects of toxic substances likely to be the contaminants of a lake.

This study was based on the determination of post-thaw semen quality, oxidant–antioxidant status and DNA-damage status of frozen Mesopotamian catfish semen. To this end, the sperm was frozen in diluent containing different inositol concentrations (5, 10, 20 and 40 mg). Increasing levels of inositol linearly increased the spermatozoa motility rate and duration significantly (p < 0.05). High doses of inositol increased antioxidants and decreased oxidants. In addition, lower intracellular DNA damage and percentage of apoptotic spermatozoa occurred in high doses of inositol (p < 0.05).Abstract: In this study, the effects of supplemented inositol on sperm extenders were examined on the spermatozoa motility rate and duration, total antioxidant and oxidant status, apoptotic spermatozoa and DNA damage, during the sperm post-thaw process of Mesopotamian Catfish (Silurus triostegus, H. 1843). The semen was frozen in diluents containing different inositol concentrations (5, 10, 20 and 40 mg). Increasing levels of inositol linearly improved the spermatozoa motility rate and duration significantly (p < 0.05). MDA and TOS were linearly decreased, however, TAS and GSH linearly increased (p < 0.05). The increasing inositol levels resulted in a linear and quadratic decrease in DNA damage in the comet assay, 8-hydroxydeoxyguanosine and the determined percentage of apoptotic spermatozoa (p < 0.05). These results suggest that there are many positive effects of the use of supplemental inositol on enhancing sperm cryopreservation efficiency in Silurus triostegus.

Abstract. Background: The pathophysiological basis of chronic kidney disease and its complications, including cardiovascular disease, are associated with chronic inflammation and oxidative stress. We investigated the effects of active vitamin D (calcitriol) and synthetic vitamin D analog (paricalcitol) on oxidative stress in hemodialysis patients. Methods: This cross-sectional study was composed of 83 patients with a minimum hemodialysis vintage of one year. Patients with a history of any infection, malignancy, and chronic inflammatory disease were excluded. Oxidative markers (total oxidant and antioxidant status) and inflammation markers (C-reactive protein and interleukin-6) were analyzed. Results: A total of 47% (39/83) patients were using active or analog vitamin D. Total antioxidant status was significantly higher in patients with using active or analog vitamin D than those who did not use (p = 0.006). Whereas, total oxidant status and oxidative stress index were significantly higher in patients with not using vitamin D when compared with the patients who were using vitamin D preparation (p = 0.005 and p = 0.004, respectively). On the other hand, total antioxidant status, total oxidant status, and oxidative stress index were similar between patients who used active vitamin D or vitamin D analog (p = 0.6; p = 0.4 and p = 0.7, respectively). Conclusion: The use of active or selective vitamin D analog in these patients decreases total oxidant status and increases total antioxidant status. Also, paricalcitol is as effective as calcitriol in decreasing total oxidant status and increasing total antioxidant status in patients with chronic kidney disease.

The aim of the present study was to evaluate the relationship between the oxidative status and the severity and type of anemia in dogs. A total of 70 dogs of various breeds, ages and of both sexes were enrolled in the study. Fifty dogs with anemia were classified according to the severity of anemia as mildly (n=18), moderately (n=18) or severely (n=14) anemic on the basis of the hematocrit (HCT) value. Anemia in the same dogs was also classified according to the type as regenerative (n=26) or non-regenerative (n=24) on the basis of the absolute reticulocyte count. Twenty dogs were used as healthy control. Total oxidant status (TOS), total antioxidant capacity (TAC) and malondialdehyde (MDA) values in plasma as well as superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) activities in erythrocyte hemolysate were measured to evaluate the oxidative status. The plasma TOS value was increased in all anemic dogs, irrespective of the severity of anemia, whereas a significant increase in the TAC value and a significant decrease in erythrocyte GSH-Px activity were observed in mild and moderate anemia. Plasma TOS and TAC values were higher in dogs with both types of anemia when compared to the healthy group. A significant increase in plasma MDA concentration and a significant decrease in GSH-Px activity were observed in the non-regenerative anemia group. There were moderate negative correlations between HCT and TOS values in the mild anemia group and between HCT and erythrocyte GSH-Px activity in the regenerative anemia group. In conclusion, oxidative stress develops in dogs with anemia, and it is largely independent of the severity and type of anemia. These results suggest that further studies with different etiologies may also be useful for evaluating the efficacy of antioxidants administered at different doses and in different combinations to treat anemia in dogs.

Background and Objective. Oxidative stress is believed to play a role in the development of preeclampsia (PE). It is known that an increased cystatin C level is also associated with PE. The aim of this study was to investigate the relationship between oxidative stress parameters and cystatin C levels in patients with severe PE. Material and Methods. Forty-four patients with severe PE and 40 healthy pregnant women were recruited for the study. All study subjects were divided into 2 groups: group 1 (n=44) consisted of patients with severe PE, and group 2 (n=40) included healthy pregnant subjects. Blood samples were obtained from all subjects in order to measure the cystatin C level, total antioxidant status, and total oxidant status. The oxidative stress index was calculated. Results. The group 1 had significantly higher cystatin C, total oxidant status, oxidative stress index levels and lower total antioxidant status level as compared with the group 2 (P=0.001, P<0.001, P<0.001, P=0.036, respectively). The serum cystatin C level was significantly correlated with the oxidative stress index (r=0.609, P<0.001). Conclusions. The present study demonstrated that both oxidative stress and cystatin C levels were increased in patients with PE, and the increased cystatin C levels seem to be a consequence of oxidative stress.

Oxidant Status

Gastroesophageal reflux disease (GERD) is a global health problem in which the prevalence is increasing over periods. This disease is a significant cause of disorders in the upper gastrointestinal tract with very complex pathogenesis. Oxidative stress (OS) due to gastric acid reflux plays a role in the inflammatory response of the esophageal epithelium. Several OS markers have been widely studied and are thought to affect the severity degree of the esophageal mucosa. However, there has been no research on total oxidant status (TOS), total antioxidant status (TAS), and OS index (OSI) in the adult with GERD; hence the aim of this review was to determine the association between TOS, serum TAS, and OSI with the GERD degree. A literature review was conducted by searching articles related to the TOS, TAS, OSI, and its correlation with GERD degree on an online database, particularly Pubmed and Google scholar. We conclude that TAS and OSI might influence the severity of GERD; however, further clinical study is needed to prove this theory.

Aim: The aim of this study was to assess the antioxidant properties of ethanolic and aqueous extracts of Punica granatum (Pomegranate) seed in testosterone induced benign prostate hyperplastic albino Wistar rats. Study design: This study is an interventional study. Place and Duration of Study: The experimental aspect of this study was conducted at the animal house, Department of Pharmacology, University of Port Harcourt between April and September, 2019. Methodology: Seventy (70) adult albino male wistar rats were used for this study. They were divided into 12 groups of 5 rats each and fed with commercial rat diet and clean drinking water. Aqueous and ethanolic extracts of Punica granatum seed were prepared using the maceration method. Benign Prostate Hyperplasia was induced in rats after they submitted to bilateral orchiectomy by daily injections of testosterone propionate (TP) (4 mg/kg b.wt.sc). Rats were treated with 500 or 1500 mg/kg b.wt. of aqueous or ethanoI extracts of Punica granatum seed, dutasteride or in combination. Administration of extracts was done by gavage. Plasma total oxidant status (TOS), total antioxidant status (TAS), superoxide dismutase (SOD) activity, were analyzed using sandwich ELISA Kits by Shanghai Korain Biotech Co., Ltd, China, while oxidative stress indices (OSI) were calculated. Statistical analysis was done using SPSS version 22.0 of Windows Stat Pac and p values less than 0.05 were considered statistically significant. Results: The results showed that the mean TOS, TAS, SOD and OSI for the rats in the normal control group were 1.66±0.2U/ml, 2.71±0.25U/ml, 41.8±2.9pg/ml and 0.62±0.10 respectively. After BPH induction (group 2), the values were 3.25±0.5U/ml,1.17±0.14U/ml, 23.38±2.09 pg/ml and 2.81±0.60pg/ml respectively. There were significant decreases for TOS and OSI, and significant increases for TAS and SOD when the rats where treated with lower and higher doses of both aqueous and ethanolic extracts of Punica granatum and Dutasteride. Conclusion: In conclusion, both doses of Punica granatum seed for ethanolic and aqueous extracts individually and in combination and with dutasteride markedly reduced total oxidant status, oxidative stress indices and improved the activities of antioxidant parameters like superoxide dismutase and total antioxidant status.
