Effect of some pesticides on in-vitro lipid and protein synthesis by the liver of the freshwater teleost, Channa punctatus (Bl.).
In vitro incorporation of (14)C-glucose/acetate into lipids and (14)C-leucine into proteins by the liver of Channa punctatus, exposed to safe application rate (SAR) and sublethal (SL) concentrations of malathion and carbaryl for 30 days (mid-February to mid-March) during the preparatory phase of the reproductive cycle, declined more in the fish exposed to SL concentrations than to SAR concentrations of the pesticides. The decline in incorporation was more marked in the malathion-exposed fish, than in those exposed to was more marked in the malathion-exposed fish, than in those exposed to carbaryl. Hence, malathion is considered more toxic than carbaryl in inhibiting the de-novo synthesis of lipids and proteins by the liver.
