Effect of a Synthetic Pyrethyroid, Cypermethrin, on Aminotransferases and Glutamate Dehydrogenase Activities in Gill, Liver and Muscles of a Freshwater Fish, Cyprinus carpio
نویسنده
چکیده
Freshwater fish, Cyprinus carpio were exposed to acute dose of cypermethrin at 7.5 μg/L for 1, 3, 5, 7 and 9 days and sub-lethal concentrations (1.5 μg/L) for 1,7, 14, 21 and 28 days to determine the change in enzyme activity in three functionally different tissues viz., gill, liver and muscle. Cypermethrin induced alterations that are both time dependent and tissue-specific, with glutamate dehydrogenase (GDH), aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) enzymes showing a significant elevation in all tissues after both lethal and sub-lethal exposure. The activities of ASAT, ALAT and GDH increased in all the tissues as exposure time increased.
