Biomarkers of monocrotophos in a freshwater fish Channa punctatus (Bloch).
Activity of a few biomarkers have been investigated on freshwater fish Channa punctatus treated with monocrotophos for acute exposure to 18.56 ppm at 96 hr and subacute exposure viz. 0.46 ppm, 0.96 ppm and 1.86 ppm for 30 days. Biomarkers such as total protein, lipid peroxidation and acetylcholinesterase have been measured in different tissues of fish viz. gills, liver, brain and muscles. The p...
متن کاملHepatic Cytochrome P450 as Biomarkers of Cypermethrin Toxicity in Freshwater Teleost, Channa punctatus (Bloch)
In this study, Channa punctatus was treated with sub-lethal concentration of cypermethrin (6.6 μg/L) for 5, 10 and 15 days and its effect on total CYP 450 and the activity of hepatic CYP450 isoforms measured. Total CYP450 content and CYP1A mediated EROD activity was significantly induced (p<0.05) in all three treated groups compared to control whereas only 15 days treated group showed significa...
متن کاملEvaluation of Genotoxicity Induced by Medicinal Plant Jatropha gossypifolia in Freshwater Fish Channa punctatus (Bloch)
The genotoxic and mutagenic potential of medicinal plant Jatropha gossypifolia, was investigated in fresh water fish Channa punctatus in the present study using micronucleus assay and comet assay. Fishes were exposed at 20% and 40% of the 24 h-LC50 value of plant extract containing Apigenin (76.48 mg L ) and crude latex (22.33 mg L). Both the test chemicals induced significant (P<0.05) genotoxi...
متن کاملDevicyprin induced gonadal impairment in a freshwater food fish, Channa punctatus (Bloch).
Synthetic pyrethroids are the recent major class of broad spectrum, photostable, organic insecticides used in agricultural, domestic and veterinary applications and now account for more than 30% of global insecticide use. Cypermethrin is metabolized and eliminated significantly more slowly by fish than by mammals or birds, which may explain this compound's high toxicity in fish compared to othe...
متن کاملEffect of Chromium trioxide on Liver biochemistry of freshwater fish, Channa punctatus (Bloch)
The present study was aimed to investigate the impact of Chromium trioxide on biochemical parameters of freshwater fish, Channa punctatus exposed to sub lethal concentration for 7, 15, 30 and 60 days. Aspartate transaminase (AST), Alanine transaminase (ALT), Orthophosphoric Monoester Phospho-hydrolase (OMP) and Orthophosphoric acid Monoester Phospho-hydrolase (OAMP) activities have been analyse...
