It is aimed to investigate the activity response of the antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase of G. pulex exposed to lead. The G. pulex was exposed synthetic solutions containing 10, 30, 50 µg/L lead for 96 h. Superoxide dismutase, catalase, glutathione peroxidase activities were determined by using ELISA kit. The differences in superoxide dismutase activities were statistically insignificant (P>0.05). Catalase decreased in all treatment groups after lead exposure (P<0.05). The glutathione peroxidase activities were decreased depending on lead exposure (P>0.05). Our findings suggest that lead can induce oxidative stress by generating reactive oxygen species and inhibiting sulfhydryl dependent antioxidant enzymes activities. In conclusion, alterations in antioxidant enzymes may potentially be used as sensitive biomarkers for risk assessment of lead in the environment and may contribute to the establishment of discharge regulations.

Naringenin, a flavonoid increases resistance against oxidative stress. The present study aims to investigate the effect of lead on lipid peroxidasyonu and some antioxidants in heart, lung, brain, spleen, muscle and the effect of naringenin on these parameters. Naringenin was administered by orogastric gavage (50 mg/kg, dissolved in corn oil) and lead acetate was given as daily 500 parts per million in drinking water for 4 weeks. In the rats exposed to lead, MDA levels in the brain, lungs, spleen and muscle tissues significantly increased (P<0.001), in the heart tended to increase but not significantly (P>0.05). Lead caused a statistically significant decrease in GSH-Px activity of the brain, spleen and muscle tissues, in CAT activity of the heart, lung and muscle tissues, in GSH concentration of the lungs and muscle tissues (P<0.05). The administration of alone naringenin caused a statistically significant decrease in MDA levels in the heart and muscle, but a significant increase in the lung (P<0.05). Although increased MDA levels in the heart, lungs, brain, muscle and spleen tissues were significantly decreased by use of the naringenin together with lead (P<0.05), increased MDA levels in the lungs and spleen tissues could not be recovered to the normal level. Generally the decreased GSH-Px and CAT activities in these tissues due to lead were significanly increased by naringenin supplementation (P<0.05). In addition, the reduced GSH levels in lung and muscle, the inceased GSH levels in heart with effect of lead were returned to the normal by naringenin. Lead particularly causes to an increase in lipid peroxidation by consuming antioxidants of cells. Naringenin was able to prevent as tissue-specific (brain, muscle) the oxidative stress caused by lead.

This experiment was conducted to determine the protective effects of flunixin meglumine and propolis on feed intake, antioxidant status and histological parameters in kidney and liver tissues in rats exposed to excessive copper. In this study individually housed thirty-six male Sprague-Dawley rats were used. Animals were randomly divided into six groups; control, copper sulphate (500 mg/kg BW/day, gavage), flunixin meglumine (2.2 mg/kg BW/day, ip), propolis (100 mg/kg BW/day, gavage), copper sulphate+flunixin meglumine (500 mg/kg BW/day of copper sulphate by gavage and 2.2 mg/kg BW/day of flunixin meglumine, ip) and copper sulphate+propolis (500 mg/kg BW/day of copper sulphate and 100 mg/kg BW/day of propolis by gavage). The study demonstrated that body weight change in the copper sulphate+propolis group significantly ameliorated in comparison with copper group (P<0.01). Propolis and flunixin meglumine administration significantly decreased MDA levels in the kidney and liver tissues, and serum TNF-α levels (P<0.001). Propolis supplementation to rats who were also treated with copper significantly increased the superoxide dismutase, catalase and reduced glutathione activities (P<0.001). Flunixin meglumine and propolis treatments decreased the copper-induced degenerative and necrotic changes with the apoptotic cells in the liver and kidney tissues. In conclusion, propolis appeared to ameliorate the adverse effects on feed intake, liver and kidney tissues seeing in the copper treatment and, apparently caused by the copper toxicity, by scavenging the free radicals and increasing activity of antioxidants.

Dört aktivasyon solusyonu hazırlanmıştır: a) NaCl (52 mM)-AS1, b) NaCl (103 mM), CaCl2 (63 mM), Glikoz (4 mM), Tris (10 mM)-AS2, c) NaHCO3 (119 mM)-AS3, d) NaCl (45 mM), KCl (5 mM), Tris (30 mM)-AS4. Sperm farklı aktivasyon solusyonlarıyla 1:100 sulandırma oranıyla aktive edilmiştir. S. coruhensis türünde en yüksek motilite oranı ve süresi pH 8’den elde edilirken O. mykiss türünde en yüksek motilite oranı ve süresi AS2 solusyonu pH 9’da elde edilmiştir. Veriler, iki tür için AS2’de ph 6-8 aralığında non-progresif motilite olduğunu göstermiştir. Sonuç olarak, sperm motilitesi ve süresi düşük pH değerlerinden olumsuz etkilemesine rağmen, Çoruh alabalığı S. coruhensis ve gökkuşağı alabalığının O. mykiss spermi geniş pH aralıklarında motil olabilir.
