The present study focused on changes in the C-reactive protein (CRP) and adrenomedullin (ADM) levels in the liver and gill tissues of Capoeta umbla as biomarkers of environmental pollution and ecosystem health in inland waters of Tunceli (Turkey). The CRP levels in liver and gills were not significantly changed in March and September at every site (p>0.05) except for site 3 in gill tissues (p<0.05). The results of statistical analysis indicate that significant differences in CRP levels were found in liver and gills among sites (p<0.05), but no changes in the gills at March (p>0.05). In March, ADM levels in gills and liver were statistically changed among sites (p<0.05), while no statistical changes were determined in September (p>0.05). The results of this study indicated that CRP levels in the tissues of the C. umbla could be utilized as a significant bioindicator for disease pathogenesis in fish infections.

Aksu, Onder; Yildirim, Nuran Cikcikoglu; Danabas, Durali; Yildirim, Numan
In this study, we determined the effects of the textile dyes Remazol Brillant Blue R (RBBR) and Congo Red (CR) on the enzymatic activities of Glutathione S-Transferase (GST), cytochrome P450 (CYP1A1) and Lactate dehydrogenase (LDH), in hepatopancreas of Astacus leptodactylus. The crayfishes were exposed to 0.5, 1.0, and 2.0 mg/l of RBBR or CR, for 24 and 48 h. The recorded GST activity clearly increased after 24 or 48 h exposure to CR, compared to a control group (p<0.05), but the changes of GST activity depending on time and dose were not statistically significant in the RRBR group (p<0.05). The activity of CYP1A1 generally decreased, but LDH activity increased in the groups exposed to different doses of CR and RBBR, when compared to their control groups. Detoxification enzymes (as GST, and CYP1A1) and metabolic enzymes (as LDH) can be proven to make useful markers for further evaluating the physiological effects of CR and RBBR on crayfish.

Yonten, Vahap; Alp, Hevidar; Yildirim, Numan; Yildirim, Nuran Cikcikoglu; Ogedey, Aysenur
This study aims to explore the optimum conditions for P. eryngii var. ferulae in adsorption of sulfamethazine (SM) from synthetic solutions via reduction of chemical oxygen demand (COD). The optimum conditions were optimized using the response surface methodology (RSM) developed by the application of the quadratic model associated with the central composite design. For this aim, RSM was employed to determine the effects of some parameters on this adsorption process by fungal biomass as an effective and available adsorbent. The investigated parameters were initial concentration of sulfamethazine (70–235 mg L−1), solution pH (3–7), adsorbent dosage (0.3–1.5 g), and contact time (5–25 min). The significant factors on each experimental design response were identified from the analysis of variance. The results of RSM analyzes revealed that optimum conditions of initial SM concentration, pH, adsorbent dosage, and contact time for maximum COD removal (82%) were achieved as 400 mg L−1, 11, 1.46 g, and 15.4 min, respectively. The results showed that dead biomass of P. eryngii var. ferulae were an appropriate adsorbent for the removal of COD in the SM medium from synthetic solutions.

This study investigates preparation of biosorbent Pleurotus eryngii immobilized on Amberlite XAD-4 and the optimal conditions for removal of Remazol Brilliant Blue R (RBBR) reactive dye from synthetic aqueous solutions. The process was optimized using the response surface methodology (RSM) developed by the application of the quadratic model associated with the central composite design. For this purpose, RSM was employed to determine the effects of operational parameters on this material as effective and available adsorbent. The investigated variables were dye initial concentration (10-60 mg L-1), solution pH (2-9), adsorbent dosage (0.1-0.5 g), and temperature (20-45 degrees C). The significant factors on each experimental design response were identified from the analysis of variance (ANOVA). The RSM indicated that optimum conditions of initial dye concentration, pH, adsorbent dosage, and temperature for maximum RBBR removal (98%) were achieved as 36.3 mg L-1, 2.0, 0.304 g, and 38.7 degrees C, respectively. The results showed that this biosorbent was an appropriate adsorbent for the removal of RBBR from aqueous solutions.

This study was aimed at screening the total antioxidant status (TAS) of genus Ricotta L. and some Grammosciadium L. from Turkey in order to find new potential sources of natural antioxidants. The TAS level of a total of 12 plant extracts from non-edible plant materials was examined. According to the results, hexanic extract of R. sinuata plant exhibited the lowest antioxidant status (2.41 mmol Trolox equivalent/l). The highest TAS level was determined in ethanolic extract of the G. daucoides (4.36 mmol Trolox equivalent/l). As a result, due to its antioxidative properties, ethanolic extract of G. daucoides can be utilized as a natural source of antioxidants.

The effects of dietary antioxidants (vitamine E, vitamine C, Astaxhantin, beta carotene) on arginase activity and nitric oxide levels of hepatopancreas and muscle of freshwater crayfish (Actacus leptodactylus) were investigated during moulting. 150 mg kg(-1) vitamine E (VE), 200 mg kg(-1) vitamine C (VC), 200 mg kg(-1) Astaxhantin and 200 mg kg(-1) beta carotene were added to experimental diets. A. leptodactylus with these diets were fed with 2% of their total weight daily, in a day during 75 days. Arginase activity was increased in muscle of crayfish fed the diets VC, VE, astaxanthin and beta karoten but in hepatopancreas arginase activity was increased with beta carotene when compared to control. NO levels in muscle were decreased when compared to control but this decrease was not statically significant. NO levels in hepatopancreas of crayfish fed the diets VC and astaxanthin were higher than control groups. Our results demonstrated that dietary antioxidants affect the arginase activity and nitric oxide level of freshwater crayfish (Astacus leptodactylus, Esch. 1823) during moulting.

Immunological biomarkers reflect the effects of exposure to environmental contaminants. In this study, the suitability and sensitivity of cytokine responses, interleukin 1 beta (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) in gill tissues of Capoeta umbla (Heckel, 1843), collected from different regions, as early warning indices of environmental pollution and ecosystem health was evaluated. Fish and water samples were taken from ten stations in March and September 2011 and 2012. Tumor necrosis factor-alpha, IL-1 beta and IL-6 levels were determined in samples of the gill tissues by using an ELISA kit. Significant variations of TNF-alpha, IL-1 beta and IL-6 levels observed between stations and seasons. The results of this study show that seasonal variations of cytokine responses in gills of Capoeta umbla are sensitive to the contaminants present in Uzuncayir Dam Lake (Tunceli, Turkey) water and are valuable biomarkers for environmental pollution and ecosystem health.

The discharge of textile effluents into the environment without appropriate treatment poses a serious threat for the aquatic organisms. The present study was undertaken to investigate biochemical response of crayfish Astacus leptodactylus exposed to textile wastewater (TW) treated by indigenous white rot fungus Coriolus versicolor. Glutathione S-transferase (GST), cytochrome P450 1A1 (CYP1A1), and acetylcholinesterase (AchE) levels in hepatopancreas and abdomen tissues of crayfish exposed to untreated, treated, and diluted rates (1/10) in both TW during 24 and 96 h were tested. Physiochemical parameters (electrical conductivity (EC), chemical oxygen demand (COD), pH, and total dissolved solid (TDS)) of TW were determined before and after treatment. Physiochemical parameters of TW decreased after treatment. The GST activity and AchE were generally increased, but CYP1A1 activity was decreased in hepatopancreas tissue of crayfish exposed to different kinds of untreated TW. After treatment by indigenous white rot fungus (C. versicolor), GST and CYP1A1 activities were returned to control values, while AchE activities were increasing further. In this study, only GST and CYP1A1 activities of A. leptodactylus confirmed the efficiency of TW treatment with C. versicolor.

The aim of this work was to determine the seasonal changes in the activities of selected biomarkers in Capoeta umbla (Heckel, 1843) caught from Uzuncayir Dam Lake (Tunceli, Turkey) and to evaluate the effects of environmental factors on these activities. Fish were sampled on seasonal basis, and superoxide dismutase, catalase, glutathione peroxidase activities and levels of glutathione and malondialdehyde in gills were determined. Significant variations of oxidative stress biomarkers were observed between seasons and sites. The results of this study show that seasonal variations of oxidative stress responses and lipid peroxidation in gills of C. umbla are sensitive to the contaminants present in water of Uzuncayir Dam Lake and selected parameters are in valuable biomarkers for monitoring of water systems, since they give an early warning signal of effects of xenobiotics on aquatic organisms at molecular levels which help to prevent their effects at organismal level.

Total antioxidant status and antifungal activities of three endemic plants from the Munzur Valley in Tunceli, Turkey; Bellevalia gracilis Feinbrun, Muscari aucheri (Boiss.) Baker ve Tulipa armena Boiss. var. lycica (Baker) Marais were evaluated for the first time. Aqueous, hexanic, methanolic and ethanolic extracts were obtained from leaves and bulbs of B. gracilis, M. aucheri ve T. armena var. lycica. Total antioxidant status was determined by using TAS assay kit (Rel assay diagnostics). Antifungal assays were performed according to amended agar method against white rot fungus Coriolus versicolor. Among the plants tested, the leaves of B. gracilis exhibited highest total antioxidant status among all samples evaluated in this study. According to the results, M. aucheri plant exhibited the lowest antioxidant status. The results of this study showed that the aqueous leaf extract of T. armena var. lycica at a concentration 2.5% (w/v) suppressed significantly the radial growth of C. versicolor by 68.00%. It can be concluded that the plant species assayed possess antifungal and antioxidant properties.

Concentrations of metals were determined in the gills, liver, kidney, heart and muscle in Capoeta umbla caught from six stations from the Munzur River system. Metal concentrations in the tissues tended to vary significantly among stations (p < 0.05). Liver (Cu, 10.10 +/- A 0.23-23.03 +/- A 9.37 ppm; Zn, 14.67 +/- A 3.01-21.82 +/- A 2.39 ppm; Cd, 18.04 +/- A 4.56-52.69 +/- A 10.65 ppb and Fe, 28.87 +/- A 6.78-115.11 +/- A 34.87 ppm) and kidney (Cu, 1.80 +/- A 0.25-3.70 +/- A 0.62 ppm; Zn, 20.81 +/- A 0.37-29.36 +/- A 0.70 ppm; Cd, 132.06 +/- A 5.29-639.51 +/- A 20.14 ppb and Fe, 24.40 +/- A 1.98-59.39 +/- A 1.97 ppm) tissues showed higher metal concentrations than other tissues. It seems that metal contamination in the river is too high for the health of fish and the people who eat them. The geographical locations of catch, season, nature of diet, and the size of fish used for analyses might lead to different metal concentration in the same fish species.

Antioxidants are our first line of defense against free radical damage, and are critical for maintaining health. The need for antioxidants becomes even more critical with increased exposure to free radicals. In the past few years there has been an increasing interest in determining relevant dietary sources of antioxidant phenolics. Mushrooms have been not only used as food materials with their unique flavor and texture, but also recognized as an important source of biologically active compound of medicinal value. In our study, to determine the antioxidant properties of the methanolic extracts of Pleurotus eryngii strains collected from different region of Tunceli, radical scavenging activity, total phenolic contents, reducing power, metal chelating activity and total antioxidant status (TAS) were analyzed. The analysis of phenolic compounds was performed by HPLC. In particular, the methanolic extract of P. eryngii collected from city center revealed the highest DPPH radical scavenging activity and reducing power, while the highest total phenolics and total antioxidant status was determined in P. eryngii collected from Pulumur. P. eryngii collected from Ovacik showed the highest chelating effects. Concentration of phenolic compounds found in three wild edible mushrooms. Kaempferol and catechin were not determined in musrooms species. The highest rutin levels were determined in ovacik. Resveratrol was determined only in Pulumur. The studied wild mushrooms might be beneficial to protect human body against oxidative damage.

Cisplatin (CP) is one of the most effective cancer chemotherapeutic agent used against various solid tumors. This study was designed to investigate the antioxidant effects of Grape Seed Extract (GSE) on CP induced oxidative damage in rabbit kidney. The material of study was consist of 18 male New Zealand rabbit. Animals were divided into 3 groups. The first group was administered a single intraperitoneal (i.p.) close of 0.9% saline. The second group of rabbits was treated with CP (a single i.p. dose of 5 mg kg(-1) body weight); The third group of rabbits was treated with GSE by gavage at the dose of 250 mg kg(-1) body weight for 6 consecutive days before and 6 consecutive days after a single i.p. CP injection. As a result of CP administration, kidney function tests; urea, BUN (Blood Urea Nitrogen) and creatinine levels were increased (p<0.001). It was observed that CP increase malondialdehide (MDA) levels, the most important indicator of oxidative damage and decreased the activity of catalasc (CAT). Administration of CP did not caused statically a change in glutathione (GSH) levels and glutathione peroxidase (GSH-P-x) activity (p>0.05). GSE treatment has high levels of MDA to compared to normal levels (p<0.001) but not an increase in CAT (p<0.05). In CP treatment group, severe acute tubular necrosis was seen. It was determined that in CP+GSE group mild degenerative changes were received instead of acute tubular necrosis. GSE has been found to be partially protective effect against CP induced biochemical and histopathological changes in rabbit kidney.

Biological compounds with antioxidant properties may contribute to the protection of cells and tissues against deleterious effects of reactive oxygen species (ROS) and other free radicals induced by cisplatin. This study was performed to investigate the possible protective role of antioxidant treatment with grape seed extract (GSE) on cisplatin-induced testes oxidant injury using biochemical approaches. The degree of protection produced by GSE was evaluated by determining the level of malondialdehyde (MDA) and glutathione (GSH), the activity of catalase (CAT), glutathione peroxidase (GSH-Px), were estimated from testes of rabbits. Male New Zealand white rabbits were divided into 3 groups (n=6): 1-Control group(1 ml saline. i.p) 2-Cisplatin group (a single dose of cisplatin (5 mg/kg, i.p) 3-A single dose of cisplatin (5 mg/kg, i.p) + GSE (250 mg/kg/day, i.p) for 6 days. MDA level were significantly higher when compared to Control (p < 0.05). In Cisplatin+grapes groups MDA levels were found significantly lower than cisplatin group (p < 0.05). GSH levels were decreased with cisplatin compared to control but in case of cisplatin+ GSE it increased (p < 0.05). In treated rabbits, the activity of CAT and GSH-Px was decreased in cisplatin and cisplatin+ GSE groups compared to control (p < 0.001). These results indicate that the antioxidant GSE might have a protective effect against cisplatin-induced testiculer damage and oxidative stress in rabbit.

In this study, the ability to decolorize two chemically different synthetic dyes (methylene blue and crystal violet) by Pleurotus eryngii strains collected from geographically different regions of Turkey was evaluated on agar plates in static liquid cultures. For all strains, growth and decolorization halos were determined on malt extract agar plates containing 0.4 and 0.6 g/L of crystal violet (CV) or methylene blue (MB). Each P. eryngii strain showed certain decolorization capacities and was able to decolorize both MB and CV under static liquid culture conditions, but not to the same extent. The presence of the dyes in static liquid culture reduced the biomass production of all strains in comparison with control culture growing in the medium without dyes. In solid medium, a positive correlation was found between growth halo and decolorization halo.
