 note = {Stage-specific and age-dependent profiles of zinc, copper, manganese, and
Selenium in testis were examined in Wistar rats by both inductively coupled
argon plasma-mass spectrometry (ICP-MS) with a microdissection technique and
in situ elemental imaging of micro-PIXE analysis. The young adult animals
(10 weeks old) contained higher levels of zinc and manganese in the
seminiferous tubules at stages VII-VIII than stages XI through VI and IX-X
and the levels were higher than those of the immature and old animals.
Copper and selenium levels at stages VII-VIII of the young adult animals
were also higher than those of the immature and old animals.    In stages
VII and VIII, zinc was higher in the central area of the seminiferous
epithelium, where spermatozoa were localized, demonstrating a cell-specific
property.},
