The present study was conducted to evaluate the effects of various levels of dietary curcumin on growth performance, haematological values, immunity and protection against Aeromonas salmonicida subsp. achromogenes infection in rainbow trout, Oncorhynchus mykiss. Fish were fed with diets containing different levels of curcumin; 0% (C), %1 (E1), %2 (E2) and %4 (E3), as treatment groups.

Effect of Tunceli garlic on some immunological parameters in Cyprinus carpio exposed to chlorpyrifos.

In this study, the effect of Tunceli garlic (Allium tuncelianium) on hemoglobin (Hb) level, oxidative radical production of neutrophils (Nitoblue tetrazolium assay-NBT activity) and total immunoglobulin (TI) content in carp (Cyprinus carpio) exposed to chlorpyrifos (CPF)  was investigated. The 96 hour LC50 value of CPF on C. carpio was calculated to as 0.

Chlorpyrifos-induced biochemical changes in Cyprinus carpio: Ameliorative effect of curcumin.

The aim of this study was to determine protective effects of curcumin on some haematological values and oxidant/antioxidant status in Cyprinus carpio exposed to chlorpyrifos. The fish were exposed to two sublethal concentrations of chlorpyrifos (0.040 and 0.

Effects of dietary propolis on the number and size of pleopadal egg, oxidative stress and antioxidant status of freshwater crayfish (Astacus leptodactylus Eschscholtz).

Four different crayfish diets; control, E1, E2 and E3, respectively containing 0, 1, 2 and 4% propolis, were tested to determine the effects of dietary propolis on the number and size of pleopadal egg, and malondialdehyde (MDA) level, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities in the freshwater crayfish (Astacus leptodactylus). The crayfish were kept at 9.6±5.

Effect of dietary n-3 polyunsaturated fatty acids on antioxidant defense and sperm quality in rainbow trout (Oncorhynchus mykiss) under regular stripping conditions.

This study examined the effect of dietary n-3 polyunsaturated fatty acids (PUFA) on malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and reduced glutathione (GSH) levels; semen and liver fatty acid compositions; and spermatological values (semen volume and pH, sperm density, percentage and duration of sperm motility) in rainbow trout (Oncorhynchus mykiss) under regular stripping conditions. For this purpose, one control and two experimental diets were prepared as isonitrogenous and isocaloric. The control diet did not contain n-3 PUFA.

Trichlorfon-induced haematological and biochemical changes in Cyprinus carpio: ameliorative effect of propolis.

Trichlorfon is among the most commonly used products to treat fish parasites in aquaculture. We investigated the effectiveness of propolis in alleviating the toxicity of trichlorfon on haematological and oxidant/antioxidant parameters in carp Cyprinus carpio. Fish were exposed to sublethal concentrations (11 and 22 mg l-1) of trichlorfon, and propolis (10 mg kg-1 of fish weight) was simultaneously administered.

Analysis of grayanatoxin in Rhododendron honey and effect on antioxidant parameters in rats.

Ethnopharmacological Relevance: Rhododendron honey, locally known as "mad honey", contains gryanotoksin (GTX) and thus induces toxic effects when consumed in large amounts. But, it is still popularly used for treating medical conditions such as high blood pressure or gastro-intestinal disorders. The aim of this study was to evaluate the effect of GTX on antioxidant parameters measured from rats fed with Rhododendron honey.

Malathion-induced changes in the haematological profile, the immune response, and the oxidative/antioxidant status of Cyprinus carpio carpio: protective role of propolis.

The present study investigated the potential ameliorative effects of propolis against malathion toxicity in the blood and various tissues of carp. The fish were exposed to sublethal concentrations of malathion (0.5 and 1 mg/L) for 10 days, and propolis (10 mg/kg of fish weight) was simultaneously administered.

Protective effect of lycopene on oxidative stress and antioxidant status in Cyprinus carpio during cypermethrin exposure.

The aim of this study was to investigate the ameliorative properties of lycopene against the toxic effects of cypermethrin (CYP) by examining oxidative damage markers such as lipid peroxidation and the antioxidant defense system components in carp (Cyprinus carpio). The fish were divided into seven groups of 10 fish each and received the following treatments: group 1, no treatment; group 2, orally administered corn oil; group 3, oral lycopene (10 mg/kg body weight); group 4, exposure to 0.202 μg/L CYP; group 5, exposure to 0.
