title: Patterns of enzyme activities in the gills of the catfish Heteropneustes fossilis (Bloch) exposed to the anionactive detergent Na-alkyl-benzenesulphonate (LAS).
abstract: The effect of sodium-alkyl-benzenesulphonate (LAS) on the activity of the respiratory enzymes of the gills of Heteropneustes fossilis (Bloch) was investigated. After 48 h exposure, the main injury to gills was the progressive separation of the lamellae from their vascular components. The enzymes of the aerobic part of the metabolism showed a decrease in activity, whereas the activity of lactate dehydrogenase was strongly increased, thus indicating that LAS has a high potential to interfere with aerobic mechanisms; however, the mode of action of it has yet to be clearly defined.
