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 کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولDNA damage and oxidative stress modulatory effects of glyphosate-based herbicide in freshwater fish, Channa punctatus.
The present study was undertaken to evaluate the genotoxic and oxidative stress modulatory effects of commercial formulation of glyphosate-based herbicide (Roundup(®)) in freshwater fish Channa punctatus. Three sublethal test concentrations of the herbicide viz., SL-I (1/10th of LC50=∼3.25mgL(-1)), SL-II (1/8th of LC50=∼4.07mgL(-1)) and SL-III (1/5th of LC50=∼6.51mgL(-1)) were calculated using ...
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 ...
