“…The inhibition of oxidative damage was reportedly closely related to the improvement in the non-enzymatic and enzymatic antioxidant capacities in fish [88]. To our knowledge, GSH is one of the most important non-enzymatic antioxidants [89]. Our results clearly showed that the GSH content in the intestine of young grass carp increased with Trp levels up to certain values, suggesting that Trp could improve the non-enzymatic capacity in fish.…”

“…Furthermore, peracetic acid appears to be more efficient than sodium hypochlorite for disinfecting wastewater (Baldry et al 1995). It may also be responsible for lower variations of antioxidant immunity in the carp than those caused by sodium hypochlorite (Elia et al 2006), leading to the assumption that peracetic acid would inflict lower oxidative stress than sodium hypochlorite. Therefore, it appears beneficial for both human beings and the environment to replace sodium hypochlorite by peracetic acid to treat wastewater and drinking water.…”

Study of the combined effects of a peracetic acid-based disinfectant and surfactants contained in hospital effluents on Daphnia magna

Hospital effluents cause environmental problems since they are 5-15 more toxic than urban effluents and they are not subjected to any pre-treatment before being discharged into urban sewage networks. The hypothesis used to explain this toxicity is the presence of disinfectants and detergents. This study is aimed at highlighting the ecotoxicity of a peracetic acid-based disinfectant to Daphnia magna, as well as the combined effects of this disinfectant in binary mixtures with three types of detergent. The detergents used here are: cetyltrimethylammonium bromide (CTAB, cationic), sodium dodecylsulfate (SDS, anionic) and Triton X-100 (TX, non-ionic). The toxicity of the mixtures is studied as a function of five predefined ratios. At the end of the study, we conclude that peracetic acid seems to be slightly toxic to Daphnia magna. Indeed, the efficient concentration inhibiting the mobility of 50% of the population of Daphnia at 24 h (EC50) is 116.6 mg/l. Globally, additive effects are observed for all the binary peracetic acid-detergent mixtures. However, for the peracetic acid-TX mixture, its effects have antagonistic tendencies whereas the peracetic acid-CTAB mixture has slight synergic tendencies. The mixture containing peracetic acid and SDS is slightly antagonistic for ratios containing more than 50% peracetic acid.

“…GR as an important enzyme of glutathione antioxidant enzyme system may synergically function with NADPH and plays an important role in removing endogenous free radicals, maintaining normal metabolism of free radicals and cell membrane integrity, and improving antioxidant capacity of the body (Elia et al 2006). Somatostatin could maintain the level of non-protein thiol group in small intestine mucosa through GR, thereby preventing the occurrence of lipid peroxidation and subsequently protecting cells and intestinal mucosa from damages due to external stimuli (Wang 1984).…”

: Effects of heat stress on somatostatin and some related immune factors in the small intestine of Wenchang chicks. Czech J. Anim. Sci., 62,[446][447][448][449][450][451][452][453][454][455] To investigate the effects of heat stress (HS) on developmental changes in immune functions of chick intestinal mucosa, one-day-old broiler chicks were randomly assigned into control check (CK) and heat-stressed (HS) groups and raised under indoor temperature. The chicks in HS group were subjected to HS at 40 ± 0.5°C from 12:00 to14:00 h every day. Intestinal mucosa samples were collected weekly during 6 weeks, and the effects of HS on somatostatin and its related immune factors were examined using immunohistochemical, physiological, and biochemical methods. The results showed that HS obviously increased the amount and integral optical density of somatostatin positive cells, somatostatin content, as well as IFN-γ and IL-2 levels in the small intestine, and these increases reached statistical significance in some intestinal segments (P < 0.05). In addition, IgG, IgA, and IgM levels fluctuated in different intestinal segments and their levels in jejunum, duodenum, and ileum in 6-week-old chicks were significantly lower in HS group than in CK group (P < 0.05). The contents of immune-related enzymes also fluctuated, but the activities of acid phosphatase, lysozyme, and glutathione reductase in duodenum and jejunum were lower in 6-week-old chicks in HS group than in CK group, some reaching statistical significance (P < 0.05). Growth hormone (GH) and HSP70 contents in multiple intestinal segments in 6-week-old chicks were significantly higher in HS group than in CK group (P < 0.05). The results indicate that (1) HS could increase the expression and secretion of somatostatin and affect the normal development of immunoglobulins, cytokines, and immune-related enzymes in the small intestine, and thereby impact the chicks' intestine immune function; (2) GH and HSP70 in the small intestine were involved in self-protection mechanisms against HS-induced intestinal injury and somatostatin regulation might be one of the important components.
