  • Title: Cypermethrin induced changes in nitrogen metabolism of fish, Tilapia mossambica.
    Author: Reddy AT, Yellamma K.
    Journal: Biochem Int; 1991 Mar; 23(4):649-54. PubMed ID: 1872879.
    Abstract:
    At sublethal concentrations, cypermethrin caused a decrease in total proteins and an increase in free amino acids, protease, alanine aminotransferase and aspartate aminotransferase in liver, brain and gill tissues of Tilapia mossambica. Nitrogen metabolic profiles like ammonia, urea and glutamine were also elevated in all the tissues as a consequence of cypermethrin toxicity. Glutamate dehydrogenase, AMP deaminase and adenosine deaminase activity was also increased in the present study.
