Toxicity of PCB 1232 on mitochondria of fish Arius caelatus (Valenciennes)

Mitochondrial proteins and phospholipids were estimated and SDH, Na(+)-K(+)-ATPase and Mg(2+)-ATPase activities were analysed in the gill, liver and heart tissues of PCB 1232 (sublethal doses) treated fish A. caelatus. Protein and phospholipids were found to be decreased significantly and SDH, Na(+)...

Description
Summary:	Mitochondrial proteins and phospholipids were estimated and SDH, Na(+)-K(+)-ATPase and Mg(2+)-ATPase activities were analysed in the gill, liver and heart tissues of PCB 1232 (sublethal doses) treated fish A. caelatus. Protein and phospholipids were found to be decreased significantly and SDH, Na(+)-K(+)-ATPase, Mg(2+)-ATPase and other enzyme systems displayed an inverse relationship with PCB dosage. Statistical analysis was carried out to indicate the relationship between sublethal doses of varying concentration and the activities of the enzyme systems involved in energy metabolism. The studies indicated impairment in mitochondrial functions.
