Ten milligram of pure gold foil was given by mouth for 16 days. Routine blood chemistry was done before and after gold therapy and repeated after 3 weeks of cessation of therapy. All the blood values were well within normal range and variations, except the enzymes-creatine phosphokinase and lactate dehydrogenase, which decreased substantially on gold foil ingestion indicating possible inhibition of these blood enzymatic activity by gold.
