“…These results are in agreement not only with ours, but also with those of Rendón-von Osten et al (9), who found a significant inhibition of GST activity in mosquito fish (G. yucatana) gills after 24 h exposure to 0.06 mg L -1 of carbofuran. GST inhibition has also been reported in gills of mosquito fish exposed to carbofuran and liver of Ancistrus multispinis exposed to deltamethrin (38). The observed decrease of GST activity may have occurred because liver and gills are two of the first organs in the contact with pesticides.…”

This study investigated the influence of the pesticide methomyl on different enzymatic activities in carp. The fish were exposed to a sub-lethal concentration (0.34 mg L -1 ) of methomyl for 15 days. On days 4 and 15, catalase (CAT) and glutathione-S-transferase (GST) activities were measured in the liver and gills. Acetylcholinesterase (AChE) activity in brain and muscle was also determined. Liver catalase activity slightly increased in exposed fish when compared to controls, but it was statistically significant only at the beginning of the experiment. No changes in CAT activity in the gills of exposed and control animals were observed (mean values were in the range 10.7-11.7 nmol min -1 per mg of protein). Liver GST activity was slightly inhibited in the exposed animals at the beginning of the study; however, it was significantly inhibited in the gills. Brain AChE activity was diminished throughout the experiment and significantly decreased after 96 h of exposure compared to controls (0.041 vs. 0.075 nmol min -1 per mg of protein; p<0.001). Our findings suggest that CAT, GST, and AChE are reliable biomarkers of effect after exposure to methomyl.

“…Also, it was reported that in hypoxia, red blood cells (RBCs) produces ROS that diffuse to endothelial cells of adjoining blood vessels (Brill et al, 2012). In turn, pesticide including neem oil inducing hypoxia and tissue anoxia (Pimpão et al, 2007;Mondal et al, 2007). However, unlike the non-nucleated mammalian red blood cells, fish erythrocytes possess very large nuclei, which may occupy about 29% of the cell volume (Wilhelm-Filho et al, 1992).…”

This study was designed to determine the effects of acute toxicity of NeemAzal T/S on Nile tilapia (Oreochromis niloticus) and to investigate the antioxidant effect of Lupine seeds on the gills and erythrocytes(EC) oxidative stress induced by NeemAzal T/S in Nile tilapia .Two doses of NeemAzal; 1/10 LC50:16 PPM (NA1) and 1/5 LC50:32 PPM (NA2) and three periods of 10, 20 and 30 days were used. Oxidative stress parameter, total peroxide (TP) and antioxidant enzyme activities, catalase (CAT) and superoxide dismutase (SOD) as well as glycemia were measured. NA2 markedly decreased CAT and SOD activities in gills and erythrocytes at most periods, but NA1 had less effect. In turn, both doses significantly enhanced TP levels in gills and EC. Moreover, hyperglycemia was detected 30 days after control (NA) exposure. LS significantly curtailed or abolished the adverse effect of NA exposure on oxidative and antioxidant parameters in gills and EC. This may be attributed to the hypoglycemic effect of LS as well as its antioxidant efficiency. In conclusion, Lupine seed exerts a potent antioxidant activity against oxidative damages induced by NeemAzal T/S in Nil tilapia fish.Int J Appl Sci Biotechnol, Vol 3(2): 170-178 DOI: http://dx.doi.org/10.3126/ijasbt.v3i2.12284

“…Nevertheless, some effort should be made to try to surpass these difficulties since these parameters can be a useful tool for evaluation of the effects of pesticides in the cellular components of blood and even in the immune system. Therefore, the analysis of hematological and biochemical parameters in fish can contribute to the assessment of the animal's health and also the habitat conditions (Pimpão et al, 2007). Table 1 provides an overview of some hematological and blood chemistry results in catfish (Rhamdia quelen) exposed to toxic chemicals.…”
