Hepatic 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 کاملBiomarkers 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 کاملTransmission electron microscopic study of gills of freshwater fish Channa punctatus (Bloch) exposed to the toxicity of cypermethrin
In the present study, an attempt has been made to examine the toxic effect of cypermethrin, a synthetic pyrethroid exposed to freshwater fish Channa punctatus. The fishes were exposed to sublethal concentration of 0.08 mg/L for 15, 30 and 45 days. The gills of the fish plays vital role in respiration and are an important organ with specific functions which are highly sensitive to many factors. ...
متن کاملtoxicological effects and molecular changes due to mercury toxicity in freshwater snakehead (channa punctatus bloch, 1973)
the objectives of this work was to examine the toxicological effect and molecular changes caused by a heavy metal pollutant mercuric chloride (hgcl2), in fresh water snakehead channa punctatus, locally known as taki fish in bangladesh. when fishes were exposed to hgcl2, it induced death of the fishes in a concentration-dependent manner. 1 mm, the highest concentration tested in this study, was ...
متن کاملChanges in the hematology of the freshwater fish, Channa punctatus (Bloch) exposed to the toxicity of deltamethrin
The freshwater fishes are an important source of animal protein to human population. They are adversely affected by aquatic pollutants such as pesticides used in agriculture, which are easily washed off into the water bodies. The effect may be direct when the pesticide is absorbed into the body through the skin, gill, intestine, wound, etc. It may be indirect when the pesticide alters the quali...
