Both trace elements and thyroid hormones play essential roles in the human body. However, the previous results about the interaction between these two factors are often controversially given. In order to make clear the influence of thyroid hormones on the homeostasis of trace elements, we studied the variation of Fe, Cu, and Zn in erythrocyte and serum from(More)

As the active center of many enzymes, trace elements play essential roles in brain function. In this work, the relative contents and distributions of elements (Cl, Br, Fe, Cu, and Zn) in two important brain regions, the cerebral cortex and(More)
