HEXAVALENT CHROMIUM INDUCED ALTERATIONS IN THE NUCLEIC ACIDS AND PROTEIN METABOLISM IN THE LIVER OF THE FINGERLINGS OF FRESHWATER SILUROID, MYSTUS (M.) VITTATUS (BL.)Abstract
Fingerlings of Mystus (M.) vittatus (Bl.) a freshwater siluroid when subjected to a sublethal concentration of 2.4 mg/l hexavalent chromium for 20 days elicited significantly decreased RNA and protein in the liver. However, 10 days of exposure under the same stress produced no significantly alteration neither in the protein content nor in the nucleic acids (DNA, RNA) content of the liver. Results are discussed in relation to pollutional stress of hexavalent chromium.
