DICHLORVOS'S HISTOCHEMICAL IMPACT ON PROTEIN AND CARBOHYDRATE IN HEPATOPANCREAS OF CYPRINUS CARPIO
*Kalyani Nandkishor
With a view to examine the effect of dichlorvos on hepatopancreas, we conducted a pilot experiment on a fish named Cyprinus carpio taking two concentrations of dichlorvos, viz. 2.5 ppm and 4.5 ppm for two different periods, ten and twenty days, respectively. Histochemical analysis carried out using periodic acid schiff’s reaction and mercury bromophenol blue after Animal Tissue Techniques by Gretchen L. Humason, showed decrement in general carbohydrate content and increment in protein content in response to the pesticide treatment. Decrease in carbohydrate content might be attributed primarily to metabolic stress while increment in protein content might show recuperation against the pesticide.
