Description
Summary:This study was undertaken to screen for some biomarkers of toxicity in the liver of Nile tilapia fish during subacute Diazinon toxicity (0.28 mgL-1 for 25 days) by using Targeted metabolomics analyses and quantitatively measure 17 amino acids, and also to monitor antioxidant status of liver (glutathione, peroxidase, catalase, superoxide dismutase and malondialdehyde). There were significant increases in branched chain amino acids valine, leucine and isoleucine (p>0.01, p>0.05and p>0.01) respectively. There was a significant increase in phenylalanine (an aromatic amino acid) P>0.05, a significant increase in lipid peroxidation (malondialdehyde P>0.001), and significant decreases in the activity of antioxidant enzymes (SOD, CAT, GSH-px) with p values (P>0.01, P>0.01, and P> 0.001) respectively. Histopathological examination showed diffuse hepatocellular necrosis with multifocal granuloma and massive hepatocellular vacuolation with congested sinusoids. It can be concluded that subacute toxicity of DZN in Nile tilapia is involved in proliferation and growth of tumor cells and negatively affects the antioxidant status of the liver.
