Özet
In this study, an enzymatic zinc determination method was applied to pleural fluid, the basis of which was the regaining of the activity of apo carbonic anhydrase by the zinc present in the sample. The method was used for pleural fluid zinc determination in order to show the application to body fluids other than serum. For this purpose, pleural fluids were obtained from 20 patients and zinc concentrations were determined. Carbonic anhydrase was purified by affinity chromatography from bovine erythrocytes. The zinc present in its structure was removed by dialysis against dipicolinic acid, resulting in apoenzyme obtained at a ratio of 100%. The activity of the enzyme was determined by the esterase action on p-nitrophenyl acetate. For comparison, the same samples were analyzed in atomic absorption. The results obtained were evaluated statistically. (\( > \)0.05 t-test, \( < \)0.001 Zn2+ (AA)-Zn2+ (apoCA), \( < \)0.005 Zn2+ (apoCA)-Total protein).
