[Superoxide dismutase activity in selected morphotic components of human peripheral blood]

The peripheral blood of 32 healthy men, aged 20-50 years, constituted material for isolating 4 cell fractions: erythrocytes, lymphocytes, granulocytes, and platelets. The adrenaline method was used to determine SOD enzymatic activity. The results of these estimations for isolated blood cells would indicate their following classification by the progressive activity values: platelets less than granulocytes less than erythrocytes less than lymphocytes. The SOD activity differences for the examined blood cells were statistically significant. Furthermore, it was found that there was a marked correlation (greater than 0.8 probability) between the SOD activity of lymphocytes and platelets, and a correlation with slightly lower probability (greater than 0.7) for erythrocytes and platelets.
