superoxide dismutase from trichuris ovis--inhibition by benzimidazoles and pyrimidine derivatives.three superoxide dismutase isoenzymes of different cellular location were detected in an homogenate of trichuris ovis. each of these molecular forms was purified by differential centrifugation and precipitation with ammonium sulphate, followed by chromatography on deae-cellulose and sephadex g-75 columns. the activity levels of the two molecular forms detected in the mitochondrial (one cyanide sensitive cu-zn-sod and the other cyanide insensitive mn-sod) were higher than that of the superoxide d ...19921343792
