STUDIES ON THE INORGANIC CHEMICAL COMPOSITION IN SKELETONS OF PLATEAU ZOKER AND PLATEAU PIKA II.ESSENTIAL TRACE ELEMENTS

The contents and distributions of 12 trace elements were analyzed in the whole length bone, cranium, backbone and legbone of plateau zoker (Myospalax baileyi) and plateau pika (Ochotona curzoniae) .The twelve trace elements are Cu, Zn,Fe,Mn,Co,Ni,Mo,Cr,F,Se,Ti and Ge.The results were as follows: The difference of the contents of only Cu in the skeleton of two kinds animals was not significant, the difference of another 11 trace elements were remarkable( P 0 05 or P 0 01),the contents of Zn,Fe,Mn,Co,Ni,Mo,F and Se of the plateau zokers were higher than the plateau pikas; Cr,Ti and Ge of the plateau pikas were higher than plateau zokers. The distribution of trace elements was not average in the cranium,backbone and leg bone,the trace elements were the richest in the cranium.
