Dalela RC, Bhatnagar MC, Tyagi AK, Verma SR: Adenosine triphosphatase activity in few tissues of a fresh water teleost, Channa gachua following in vivo exposure to endosulfan. Toxicology. 1978 Dec;11(4):361-8. Fresh water teleost fish, Channa gachua, were chronically exposed to various sublethal concentrations of endosulfan (0.00534, 0.00355, 0.00213 and 0.00174 mg/1) at 25 +/- 4 degrees C for 30 and 60 days respectively. The study shows enzyme inhibitions, greatest in oligomycin-insensitive Mg2+ ATPase in brain, gill and liver tissues, with pronounced effects at highest endosulfan concentration for 60 days exposure. However, in kidney the highest inhibition was of oligomycin-sensitive (mitochondrial) Mg2+ ATPase. The study indicates that endosulfan interferes with energy metabolism in vivo. The marked sensitivity of mitochondrial Mg2+ ATPase to endosulfan is suggestive of the potential for endosulfan to interfere markedly with various energy requiring processes in the fish body. |
