Plasma metabolites, ions and thyroid hormones levels, and hepatic enzymes׳ activity in Caspian roach (Rutilus rutilus caspicus) exposed to waterborne manganese

The response of thyroid hormones, biochemical and enzymological biomarkers to pyrene exposure in common carp (Cyprinus carpio)

“…Although the ionoregulatory parameters have been extensively studied in the toxicity assessment of heavy metals (Beaumont et al, 2000;Hoseini et al, 2014;Katuli et al, 2014a;Sathya et al, 2012), pharmaceuticals (Saravanan et al, 2011), alkylphenols (Sayed et al, 2011;Carrera et al, 2007) and pesticides (Suvetha et al, 2010;Katuli et al, 2014b), these biomarkers have been less used in the toxicology of PAHs. Our study demonstrated that the plasma electrolytes (sodium, potassium and calcium) are less suitable endpoints for the study of pyrene exposure as at all of the concentrations examined, pyrene did not significantly alter plasma ion level.…”

“…Plasma levels of T 3 and T 4 were measured based on competitive ELISA using anti-T 3 and anti-T 4 monoclonal antibodies, respectively, and PISHTAZ TEB commercial ELISA kits (Hoseini et al, 2014). All procedures were performed according to the manufacturers' instructions.…”

“…All procedures were performed according to the manufacturers' instructions. Plasma potassium and sodium concentrations were determined using a flame photometer (Hoseini et al, 2014).…”

Toxicological effects of clofibric acid and diclofenac on plasma thyroid hormones of an Indian major carp, Cirrhinus mrigala during short and long-term exposures

“…Significant increase in T 3 and T 4 levels has been observed in Caspian roach (Rutilus rutilus caspicus) exposed to waterborne manganese (Hoseini et al, 2014) and in zebrafish exposed to butachlor (Chang et al, 2013). Maclatchy and Eales (1990) suggest that an increase in T 4 level could be a consequence of the decreased GH levels.…”

Effects of manganese on fat snook Centropomus parallelus (Carangaria: Centropomidae) exposed to different temperatures

“…Numerous studies have shown that the effects of manganese on fish include impaired functions of the gill epithelium, such as hydromineral imbalance (Gonzalez et al, 1990) and histopathology of the gills (Dalzell, Macfarlane, 1999;Hedayati et al, 2015;Dolci et al, 2017). Impacts on hematology (Agrawal, Srivastava, 1980;Wepener et al, 1992), immunomodulation (Cossarini-Dunier et al, 1988;Hernroth et al, 2004), and hormonal interference (Hoseini et al, 2004) can also occur. Other damages on the metabolic system were also observed, such as impacts on carbohydrate metabolism (Nath, Kumar, 1987;Barnhoorn et al, 1999;Partridge, Lymbery, 2009) and alterations to the antioxidant system (Falfushynska et al, 2011;Vieira et al, 2012;Dolci et al, 2013;Gabriel et al, 2013).…”
