The present study was conducted to evaluate the growth, immunity, haematology, antioxidant components and resistances to Aeromonas hydrophila infection in the common carp, Cyprinus carpio fed quercetin (QUR) enriched diet. A number of 360 fish (30.5 ± 1.5 g) were distributed into 12 tanks (30 fish/tank) in three replicates and fed experimental diets containing 0% (control), 0.1% (1 g/kg diet), 0.5% (5 g/kg diet) and 1% (10 g/kg diet) QUR for 60 days. Based on the results, the survival and growth performance (weight gain [%], specific growth rate and feed conversion ratio) improved in response to dietary QUR (p < 0.01). The analysis of fish body composition indicated higher content of protein in 0.5% and 1% QUR-supplemented fish compared to others (p < 0.01). The plasma (complement activity, IgM content, lysozyme activity, bactericidal activity, total protein, total albumin) and mucus (IgM content, lysozyme activity) immune components significantly increased almost all in the supplemented fish compared to those in the control group; however, the highest values were observed in group of 1% QUR (p < 0.01). The mucosal protease and alkaline phosphatase increased only in fish fed 1% QUR (p < 0.01). The expression of the immune-related genes (C3, Lyz and IgM) significantly increased in response to 0.5 and 1% QUR compared to control (p < 0.01). The expression of the inflammatory genes, tumour necrosis factorα (TNFα) and interleukin-8 (IL-8) significantly declined in fish fed 1% QUR compared to supplemented fish. The activity of liver antioxidant enzymes [superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT)] was also increased by QUR supplementation. The highest liver antioxidant enzyme activity was found in group of 1% QUR (p < 0.01). The QUR supplementation also affected haematology of the fish. In this regard, the values of RBC, Hct and WBC significantly elevated in response to dietary QUR (p < 0.01). The MCHC and MCH indices significantly increased in fish fed 0.5 and 1% QUR compared to other diets (p < 0.01). As an indicator of oxidative stress, the levels of malondialdehyde (MDA) showed no significant differences between the experimental groups (p > 0.01). The fish supplemented with 0.5 and 1% QUR significantly showed higher survival rate after challenge with A. hydrophila compared to other experimental groups (p < 0.01). In conclusion, QUR at optimal

Dialysis water is vital because of various harmful contaminants for patients. The aim of this study was to assess the efficiency of hemodialysis instruments in the removal of microbial and chemical pollutant in educational hospitals affiliated to Ahvaz Jundishapur University of medical sciences, Iran during 2018–2019. This cross-sectional descriptive research studied the microbial and chemical water quality of hemodialysis instruments in Razi, Sina, and Golestan hospitals in Ahwaz, Iran. 72 samples of microbial parameters and 24 samples of chemical parameters were collected from water used in hemodialysis instruments, including microbial characteristics (the total coliform, fecal coliform and heterotrophic bacteria counts) and chemical characteristics (pH, turbidity, PO4, Cl, Mg, So4, Ca, NO2, and EC) at Razi, Imam, and Golestan educational hospitals on all weekdays during 2018-2019. In this study, experiments were done according to the current standard methods, EPA from hemodialysis instruments. Finally, using SPSS18 software and descriptive statistics, the relationship between results at the removal of toxic, microbial, and chemical pollutants in different months and hospitals was investigated. this study showed that the average concentration of chemical characteristics during the warm season at Razi, Imam, and Golestan educational hospitals for pH, Turbidity, PO4, Cl, Mg, So4, Ca, NO2, and EC were (6.867, 6.4475, 6.53); (2.985, 3.035, 1.226); (0.075, 0.245, 0.195); (38.5, 21.965, 144.87); (1.552, 1.657, 39.445); (8.6, 4.5, 21.5), (2.09, 3.187, 78.975); (0.0082, 0.038, 0.155), and (125.25, 70.35, 78.35), respectively during 2018. Also, during 2019, results showed that the average levels of amounts for pH, Turbidity, PO4, Cl, Mg, So4, Ca, NO2, and EC in Razi, Imam, and Golestan educational hospitals were (7.077, 7.252, 6.435), (1.725, 0.595, 4.16), (0.0775, 0.0597, 0.0297), (52.33, 138.81, 20.92), (23.52, 18.227, 8.767), (35, 27.25, 4.05), (14.58, 28.152, 9.25), (0.0067, 0.0045, 0.0032), and (210.52, 121.62, 29.16), respectively. According to the results, hemodialysis instruments in Razi and Imam have a 90% efficiency in removing heterotrophic bacteria counts (HPC). Based on these findings, educational hospital hemodialysis equipment effluent in Ahvaz, Iran was mitted to Iran environmental standards for use in hemodialysis machines. The result showed that the removal percentage level of microbial and chemical pollutants by the hemodialysis process is comparatively suitable. It should be mentioned that in the proper operation and reconstruction, hemodialysis systems can have an increased rate of removal of microbial and chemical pollutants.
