title: [Changes in 6 trace elements during development of normal fetus vertebrae].
abstract: Six elements: calcium, iron, zinc, copper, manganese and magnesium were detected in the central epiphyses of first lumber vertebrae in 60 normal aborted fetus, aging from 9 to 32 weeks, by method of AAS. Iron, copper, manganese and zinc reached to their high levels during 9-20 weeks, which were related to the formation of cartilage vertebrae. Calcium and magnesium, showed a significant relationship, and then gradually got to their high value after 16 weeks after ossification and remained at a constant level during later period. The data indicated that different elements should be given in different stage of fetus development.
