| Abstract: | The reference ranges of the trace elements Al, As, Be, B, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, Li, Rb, Se, Sr, and Zn were determined
by inductively coupled plasma-mass spectrometry (ICP-MS) in sera of a group of free-ranging plains viscachas of the pampa
grasslands of Argentina. The values were compared with those of a small group of captive plains viscachas of the Zurich Zoo
with diabetes and bilateral cataracts. In addition, a method for digestion of whole-blood samples is described for the trace
element determination. Significant differences in the concentration of trace elements in the two groups of animals are discussed.
No correlation was found between the levels of selenium and of other trace elements compared to the formation of cataracts. |
