Toxicological studies of methanol on superoxide dismutase (SOD) activity of freshwater fish Cirrhinus mrigala
Author(s): Desai TH and Bhilave MP
Abstract: Superoxide dismutase is an enzyme that alternately catalyzes the dismutation of the superoxide (O
2−) radical into two less damaging species: either molecular oxygen (O
2) or hydrogen peroxide (H
2O
2).
Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. The present study was designed to evaluate the effect of Methanol on the Superoxide dismutase (SOD) activity on freshwater fish,
Cirrhinus mrigala. Alteration in fish anti-oxidant enzyme i.e., SOD concentration was measured in tissues exposed to lethal and sublethal concentration of Methanol for 4(acute) and 30(chronic) days. LC
50 was measured and was observed to be 12.50 ml/l. Superoxide dismutase (SOD) activity tend to increase in different tissues of exposed fish in order of Liver > Muscle > Gill > Brain at both the lethal and sublethal concentrations of Methanol. The increased SOD activity in
Cirrhinus mrigala reflects a toxicant induced damages in fishes.
