106 burned patients were divided into two groups: group L consisted of 57 patients with burns larger than 30% TBSA, and group S consisted of 49 patients with burns smaller than 30% TBSA. The contents of Zn, Cu, Fe, Ca, Mg in serum, urine and blister fluid were determined on 1, 2, 3, 7, 14, 21, 28 days after burn injury. The results indicated that all of the elements in serum were decreased except serum Fe on first day, and the levels were much lower in group L than in group S. The contents of Zn, Cu, Fe in urine were increased significantly and Ca, Mg in urine decreased. The contents of Zn, Fe, Ca in blister fluid were similar to normal values of serum, and Cu, Mg in blister fluid were less than that of serum. The studies indicated that the decrease in contents of Zn, Cu, Fe, Ca, Mg after burn injury was propably related to loss of these elements from urine and wound.
