Effects of Cypermethrin on the Superoxide Dismutase Activity of Macrobrachium nipponense
Abstract:
To determine the effects of dietary selenium (Se) supplementary on muscle superoxide dismutase (SOD) activity, oriental river prawn, Macrobrachium nipponense were exposed to three commonly used pesticides - cypermethrin. For each concentration of each pesticide, the shrimps were grouped into control diet group, inorganic Se group and organic Se group. For each concentration of each pesticide, the order of total SOD activities were organic Se diet group > inorganic Se diet group > control diet group. With the increasing concentrations of pesticides, the total SOD activities increased first and then decreased dramatically. This study indicated that Se supplementary in diet could enhance the resistance of shrimps against low concentrations of ambient contaminants.
