“…This condition is associated with increasing GSH-px activity and decreasing the TBARS concentration in fish tissue (Table 3). A positive relationship between the Se content of the diets and GSH-px activity was also reported by Bell et al (1987) in Salmo salar, Lin and Shiau (2005) in Epinephelusma labaricus, and Zhou et al (2009) in Carassius auratus gibelio. Increasing the Se level of the diets led to higher deposition of Se in the liver.…”

“…An increase in the fat content of the diet may lead to a higher level of non-enzymatic antioxidants, thereby increase the Se requirement. Moreover, most previous experiments in dietary Se requirements for rainbow trout and Atlantic salmon were conducted using mineral Se (Hilton et al, 1980;Bell et al, 1986Bell et al, , 1987Talas et al, 2008). This has been reported to have lower bioavailability and trophic transfer properties compared with organic Se (selenomethionine) (Lorentzen et al, 1994;Wang and Lovell, 1997;Fan et al, 2002).…”

“…As glutathione peroxidase (GPX), a selenium-containing enzyme, contributes to the decomposition of hydrogen peroxide [32], selenium can be regarded as a micronutrient that indirectly protects the cells of an organism from serious damages caused by the presence of hydrogen peroxide [32]. Therefore, dietary supplementation with a combination of vitamin E and selenium may protect cell membranes against lipid oxidation [33,34] and exert synergistic effect in hydroperoxide detoxification [33].…”

“…Samples were weighed, homogenized and saponified as described by Bieri (1969), but using a single-step hexane extraction (Bell et al, 1987). Recovery of α-tocopherol using this method was reported as 100.5% ± 1.3.…”

Increased activities of hepatic antioxidant defence enzymes in juvenile gilthead sea bream (Sparus aurata L.) fed dietary oxidised oil: attenuation by dietary vitamin E

Previously, we had shown that altering the highly unsaturated fatty acid(HUFA)/vitamin E ratios in sea bream (Sparus aurata) livers significantly affected their peroxidation status, with fish fed the diet rich in HUFA and low in vitamin E showing significantly higher values of lipid peroxidation products, without, however, significant effects on liver antioxidant defence enzyme activities. The aim of the present trial was to further characterise the biochemical indicators of peroxidative stress in juvenile sea bream. A high pro-oxidative stress was induced by feeding diets containing around 7% of the dry weight as n-3HUFA. The potential peroxidative stress was increased by oxidising the oil, increasing the peroxide value of the oil some 10-fold. These oils were fed without or with supplemental vitamin E (α-tocopherol acetate at 200 mg.kg -1 dry diet) giving four diets in total. Fish were sampled after 30 and 60 days of feeding the experimental diets. None of the diets had any serious deleterious effects on growth and mortality of the fish during the trial. Similarly, there were few significant effects due to dietary oxidised oil or supplementary vitamin E on liver lipid and fatty acid profiles of livers and, in particular, the proportions of HUFA were not decreased by dietary oxidised oil. The vitamin E content of the liver reflected the vitamin E contents of the diets but was also affected by dietary oxidised oil being reduced by oxidised oil in fish fed diets without supplemental vitamin E but, unexpectedly, increased by oxidised oil in fish fed diets supplemented with vitamin E. Liver TBARS levels were significantly lower in fish fed diets supplemented with vitamin E whereas dietary oxidised oil had no major effects on lipid peroxidation products. Catalase and superoxide dismutase activities were both increased in fish fed dietary oxidised oil and reduced by supplementary vitamin E after 30 days feeding.In contrast glutathione peroxidase was less affected by the diets, and the activities of glutathione-S-transferase and glutathione reductase were only reduced by dietary vitamin E after 60 days of feeding. However, all the enzyme activities were significantly affected by the duration of feeding, but the number of interactions between the three factors (time, oil and vitamin E) showed that the relationships were complicated. In conclusion, the present study showed that feeding diets containing oxidized oil significantly affected the activities of liver antioxidant defence enzymes and that dietary vitamin E partially abrogated these effects.Growth and survival of the fish were relatively unaffected suggesting that the responses in sea bream offered effective protection. However, the duration of feeding the diets of high pro-oxidative stress was observed to have a hitherto unknown effect, possibly the result of an adaptive process, but which requires further investigation.
