| Abstract | ||
| The effects of four pesticides on the activity of six enzymes were examined in vitro in different tissues of the cat fish, Ictalurus punctarus. The ATPase activity in brain and muscle was decreased by endosulfan, ʎ- cyhalothrim, and triphenyltin acetate. Thiodicarb did not show specific affinity to ATPase. The acetyl choline esterase (AChE) activity in brain was inhibited by thiodicarb, whereas endosulfan and, ʎ- cyhalothrim caused much less inhibition. Tri phenyl tin acetate did not show any interaction with acetylcholinesterase (AChE), acid phosphatase (AcP), alkaline phosphatase (AlP), glutamate-oxaloacetate transaminase (GOT), and glutamate-pyruvate transaminase (GPT). The hepatic ACP in kidney was inhibited by endosulfan, thiodicarb, and ʎ- cyhalothrim. In the liver, however, the ACP activity was generally enhanced. The AlP activity was increased by endosulfan and thiodicarb in the kidney. In the liver, the AlP activity was decreased with eadosulfan and thiodicarb. The GOP was inhibited in the kidney and liver by endosulfan and thiodicarb. The CPT activity was increased by two pesticides in the liver and muscle. ʎ- cyhalothrim did not show any interaction with AIP, GOT and CPT. | ||
