[Determination and analysis of some serum trace elements of active pulmonary tuberculosis]

The concentration of serum Zn, Ca, Cu, Mg in 72 cases of active pulmonary tuberculosis group (including 60 cases with treatment and 12 without treatment) and in 43 cases of healthy group were determined. The results showed that the tuberculosis patients have a decrease of Ca and increase of Cu. There is a reduction of Zn after treatment. There are notable differences of the serum Ca, Cu and Zn content between the tuberculosis and the healthy group, while the difference of Mg is not remarkable. The above results could be used to reveal the regularity of serum element change in tuberculosis and to seek a new clue to the occurrence and treatment of this disease.
