[Biochemical findings in osteoporosis. II. The importance of zinc].
The authors examined 33 cases of senile, 18 cases of postmenopausal and 9 cases of medicamentous osteoporosis and assessed serum and red cell zinc content. The mean blood levels of zinc were highest in the group of medicamentous osteoporosis. In all three groups the zinc level was reduced more frequently in serum than in red cells.
