“…7,8) In our previous study, isolation stress resulted in a reduced AA content of lymphocytes, markedly and moderately in the olive oil-fed and soybean oil-fed mice respectively. 4) In addition, isolation stress led to decreased IFN-production in concanavalin A-stimulated lymphocytes from olive oil-fed but not soybean oil-fed mice, and caused reduced IL-6 production in these lymphocytes from olive oil-and soybean oil-fed mice. 4) In contrast, in the present study, in the olive oil-fed mice, isolation stress enhanced rather than suppressed infection-induced IFN-production in the liver as compared with group-housed counterparts (Table 4).…”

“…3) In our previous study, 2 weeks of social isolation stress reduced mitogen-stimulated lymphocyte proliferative responses and altered cytokine production by lymphocytes. 4) These isolation stress-induced modulations were more profound in olive oil-fed mice than soybean oil-or fish oil-fed mice. It has been reported that psychological stress can modulate the fatty acid composition of total lipids in liver, lymphocytes, and serum.…”

“…It has been reported that psychological stress can modulate the fatty acid composition of total lipids in liver, lymphocytes, and serum. [4][5][6] Our previous study showed that isolation stress reduced the arachidonic acid (AA) content of lymphocytes markedly, moderately, and not at all in olive oil-, soybean oil-, and fish oil-fed mice respectively. 4) AA is precursor of prostaglandins, leukotrienes, and related compounds, which have important roles in inflammation and in the regulation of immunity.…”

“…Glutathione peroxidise (GSH-Px) functions to remove ROS and protect from the damage caused by oxidative stress (Halliwell and Gutteridge 1999). Many markers, hsp70, metallothionein-Aisoform and ubiquitin, had been used to evaluate the perturbations in cell function resulting from increased heat stress and inflammatory stress respectively in mammals (Maiorino et al, 1991;Arai et al, 1999;Aufricht et al, 2005;Bremner and Beattie 1990;Oarada et al, 2007), which are nonspecific immune response related genes.…”

To investigate the effects of green tea waste on growth and health of grass carp (Ctenopharyngodon idellus), Green tea waste (GTW) and green tea (GT) were added in the basal diet (BD) of fish by replacing wheat at an inclusion level of 5% to form three diets. 60 grass carp (43.8±2.8 g) were divided into three groups (each group having two replicates) and fed for 66 days. After which growth and health of fish were determined. The results showed that final weight of fish and feed efficiency ratio in GTW group were between BD and GT groups and they were not different compared with BD or with GT groups. Expression of muscle myf5 and myf6 in GTW were between BD and GT group, being significantly lower than BD group. Serum TP, ALB, GLO, HDL, LDL and T-AOC in GTW group were significantly higher than BD group. Expression of hsp 70 and ubiquitin in hepatopancreas of fish in GTW group were significantly higher than BD group. The results suggest that GTW supplementation has positive impact on health of fish without affecting the growth of fish.

To study the substitution of fish oil by vegetable oils in fish diets, juveniles Senegalese sole (Solea senegalensis) were fed diets (56 % crude protein, 12 % crude lipid) containing either linseed (100LO) or soybean (100SO) oils in comparison with a 100 % fish oil-based diet (100FO) for 90 days. Samples of muscle, liver, and intestine were collected for biochemical analysis and for glucocorticoid receptor-related genes, including GR1 and GR2, and the associated heat shock proteins HSP70, HSP90AA, and HSP90AB. Besides, basal levels of plasma cortisol were also determined. After the feeding period, a stress test, consisting on 5 min of net chasing, was applied to a selected population of each dietary group. Total replacement of fish oil by vegetable oils did not induced changes in fish growth and performance, but affected fatty acid profile of muscle, liver, and intestine, reflecting those tissues the characteristic fatty acids of each type of dietary oil. A tendency to conserve the ARA/EPA ratio could be observed in the different tissues, despite of the level of these fatty acids in diet. Chasing stress induced an increase of muscle GR1 and a reduction in intestinal GR2 relative expressions at any of the experimental diets assayed. In liver, chasing stress induced an increase in both GR1 and GR2 gene expression in fish fed fish oil diets. Similarly, chasing stress induced an increase of muscle HSP70 and decrease of HSP90AB in liver at any of the experimental diet assayed. Besides, vegetable oils decreased the expression of HSP70 in intestine, being the relative expression of liver HSP90AA increased by the inclusion of linseed oil in the diet, at any of the experimental conditions assayed.
