Abstract:
Objective To explore the relationship between trace elements proportion in food and health. Methods 45 mice aged 12 month were randomly divided into 3 groups: control group(n=16) and two experimental groups(n=15).The mice in the experimental groups were given Zn, Li, Fe, Se, Mn, Cu, Co in different proportion by food for 60 days, then all mice were sacrificed, thymus weight, spleen weight, thymus coefficient, spleen coefficient, bone indexes were determined. Results Supplementation of the trace elements in food increased the content of Ca2+ in the bone of the aged mice and proportion variety of trace elements might induce the changes of thymus weight, spleen weight, spleen coefficient and bone indexes. Conclusion The reasonable proportion of trace elements in food could increase the content of bone Ca2+ in aged mice.
