- Abstract
Presently, aquatic pollution by ammonium compounds, due to their large scale production and the indiscriminate usage for the agriculture and aquaculture forms, has earned an important place among the environmental pollutants. Industrial effluents, bio degradation of waste products and food remains also contribute for the formation of considerable quantity of ammonia in the environment. Ammonia is toxic to living animals and produces several biochemical and physiological changes at cellular level when present in higher concentration. In view of these some of the important physiological and biochemical events occurring under ammonia in the fish animal were taken for the study. Fish Cyprinus carpio is taken for the present study. Animal weighting 120±10 g and 17±2 cm length are exposed to 4 ppm of ammonia solution for 7days. In order to understand the effect of chronic ammonia stress on the detoxification aspect of the brain tissue, activity levels of arginase, Glutathione peraxidase (GPx), Glutathione s-Transferase(GST),Glutamine Synthetase(GSH), Glutamate dehydrogenase (GDH),Xanthine Oxidase (XOD),Catalase (CAT), Superoxide dismutase(SOD) enzyme levels were estimated in the brain tissue of the animal, increased activity levels in Arginase, GPx, GST,GSH, GDH , XOD, CAT and SOD enzyme levels was observed on prolonged ammonia exposure.
